The Low-Shrinkage, Crack-Free Mix (per cubic yard)

High Range Water Reducer: Eucon 37 - 74 oz

· Heavy Duty Concrete Pad

· Construct a heavy duty reinforced concrete pad.

· Construct heavy duty floor by placing a heavy-duty bonded topping on a bases lab which has had a rough slab finish left 50 mm 2 inches below final grade. Concrete in the base slab must be thoroughly hardened but not more than 30 hours old. The temperature of the fresh concrete topping must not vary more than 5 degrees C 10 degrees F plus or minus from the temperature of the base slab. The ambient temperature of the space adjacent to the concrete placement and of the base slab must be between 10 and 30 degrees C50- and 90-degrees F.

· The contractor shall provide the following:

· Preparation Slab

· Keep the base slab continuously damp until topping is placed. Thoroughly clean the surface of the base slab with an air-water jet immediately before placing the topping. Thoroughly scrub a thin coat of neat cement grout of about the consistency of thick cream into the existing surface immediately ahead of the overlay placing. At the time the neat cement grout is placed, the existing concrete surface must be damp but no free water present.

Deposit the overlay concrete before the grout coat has had time to stiffen.

CONCRETE PAD HARDENER

· Treat the concrete pad with a hardener applied after the concrete has been cured and then air dried for 14 days. Apply three coats, each the day after the preceding coat was applied. For the first application, dissolve 0.5 kg one pound of the silicofluoride in 4 liters one gallon of water. For subsequent applications, the solution must be 1.0 kg two pounds of silicofluoride to each 4 liters gallon of water. Mop the floor with clear water shortly after the preceding application has dried to remove encrusted salts. Apply proprietary hardeners in accordance with the manufacturer's instructions. Ventilate the area during application. Take precautions when applying silicofluoride due to the toxicity of the salts. Immediately remove any compound that contacts glass or aluminum with clear water.

EXTERIOR SLAB AND RELATED ITEMS TESTING AND INSPECTION FOR CQC

· Perform the inspection and tests described below and, based upon the results of these inspections and tests, take the action required. Submit certified copies of laboratory test reports, including mill tests and all other test data, for Portland cement, blended cement, pozzolan, ground granulated blast furnace slag, silica fume, aggregate, admixtures, and curing compound proposed for use on this project.

· When, in the opinion of the Contracting Officer, the concreting operation is out of control, cease concrete placement and correct the operation.

· The laboratory performing the tests must be onsite and conform with

ASTM C1077. Materials may be subjected to check testing by the

Government from samples obtained at the manufacturer, at transfer points, or at the project site.

· The Government will inspect the laboratory, equipment, and test procedures prior to start concreting operations and at least once for conformance with ASTM C1077.

· Grading and Corrective Action.

· Fine Aggregate.

· Concrete Mixture.

· Air Content Testing

Perform air content tests when test specimens are fabricated. In addition, make at least two tests for air content on randomly selected batches of each separate concrete mixture produced during each 8-hour period of concrete production. Perform additional tests when excessive variation in workability is reported by the placing foreman or Government inspector.

Conduct tests in accordance with ASTM C231/C231M for normal weight concrete and ASTM C173/C173M for lightweight concrete. [Plot test results on control charts. Submit the control charts weekly and make them readily available to the Government. Keep copies of the current control charts in the field by testing crews and results plotted as tests are made. When a single test result reaches either the upper or lower action limit, perform a second test immediately. Average the results of the two tests and use this average as the air content of the batch to plot on both the air content and the control chart for range, and for determining need for any remedial action. Plot the result of each test, or average as noted in the previous sentence, on a separate control chart for each mixture on which an

"Average line" is set at the midpoint of the specified air content range from paragraph AIR ENTRAINMENT. Set an upper warning limit and a lower warning limit line 1.0 percentage point above and below the average line, respectively. Set an upper action limit and a lower action limit line 1.5 percentage points above and below the average line, respectively. Plot the range between each two consecutive tests on a secondary control chart for range where an upper warning limit is set at 2.0 percentage points and an upper action limit is set at 3.0 percentage points. Samples for air content may be taken at the mixer, however, the Contractor is responsible for delivering the concrete to the placement site at the stipulated air content. If the materials or transportation methods cause air content loss between the mixer and the placement, take correlation samples at the placement site as required by the Contracting Officer/COR, and the control the air content at the mixer as directed.

· Air Content Corrective Action

Whenever points on the control chart for percent air reach either warning limit, immediately make an adjustment in the amount of air-entraining admixture batched. As soon as practical after each adjustment, make another test to verify the result of the adjustment. Whenever a point on the secondary control chart for range reaches the warning limit, recalibrate the admixture dispenser to ensure that it is operating accurately and with good reproducibility. Whenever a point on either control chart reaches an action limit line, the air content is considered out of control and the concreting operation immediately halted until the air content is under control. Make additional air content tests when concreting is restarted.

· Slump Testing

In addition to slump tests which are made when test specimens are fabricated during concrete placement/discharge, make at least four slumps tests on randomly selected batches in accordance with ASTM C143/C143M for each separate concrete mixture produced during each 8-hour or less period of concrete production each day. Also, make additional tests when excessive variation in workability is reported by the placing foreman or

Government inspector. Plot test results on control charts. Submit the control charts and make them readily available to the Government. Keep copies of the current control charts in the field by testing crews and results plotted as tests are made. When a single slump test reaches or goes beyond either the upper or lower action limit, immediately perform a second test. Average the results of the two tests and use this average as the slump of the batch to plot on both the control charts for slump and the chart for range, and for determining need for any remedial action. Set limits on separate control charts for slump for each type of mixture. Set the upper warning limit at 12.5 mm 1/2 inch below the maximum allowable slump specified in paragraph SLUMP in PART 1 for each type of concrete and, set an upper action limit line and lower action limit line at the maximum and minimum allowable slumps, respectively, as specified in the same paragraph. Plot the range between each consecutive slump test for each type of mixture on a single control chart for range on which an upper action limit is set at 50 mm 2 inches. Take samples for slump at the mixer. However, the Contractor is responsible for delivering the concrete to the placement site at the stipulated slump. If the materials or transportation methods cause slump loss between the mixer and the placement, take correlation samples at the placement site as required by the Contracting Officer, and the slump at the mixer controlled as directed.

· Slump Corrective Action

Whenever points on the control charts for slump reach the upper warning limit, make an adjustment immediately in the batch weights of water and fine aggregate. The adjustments are to be made so that the total water content does not exceed that amount allowed by the maximum w/c ratio specified, based on aggregates which are in a saturated surface dry condition. When a single slump reaches the upper or lower action limit, deliver no further concrete to the placing site until proper adjustments have been made. Immediately after each adjustment, make another test to verify the correctness of the adjustment. Whenever two consecutives individual slump tests, made during a period when there was no adjustment of batch weights, produce a point on the control chart for range at or above the upper action limit, halt the concreting operation immediately, and take appropriate steps to bring the slump under control. Make additional slump tests as directed.

· Temperature

Measure the temperature of the concrete when compressive strength specimens are fabricated in accordance with ASTM C1064/C1064M. Report the temperature along with the compressive strength data.

Strength Specimens

Perform on at least one set of test specimens, for compressive strength as appropriate, on each different concrete mixture placed during the day for each 380 cubic meters 500 cubic yards or portion thereof of that concrete mixture placed each day. Perform on additional sets of test specimens, as directed by the Contracting Officer when the mixture proportions are.

changed or when low strengths have been detected. Develop a truly random

(Not haphazard) sampling plan for approval by the Contracting Officer prior to the start of construction. Show in the plan that sampling is done in a completely random and unbiased manner.

· A set of test specimens for concrete with a 28-day specified strength in accordance with paragraph STRENGTH REQUIREMENTS in PART 2 consists of five specimens, two to be tested at 7 days, two at 28 days, and one cylinder held in reserve.[ A set of test specimens for concrete with a

[56-day] [90-day] strength in accordance with the same paragraph consists of eight specimens, two tested at 7 days, two at 28 days, two at [56] [90] days, and two held in reserve.

· A strength test is the average of the strengths of at least two 150 mm by 300 mm 6 inch by 12-inch cylinders or at least three 100 mm by 200 mm

4 inches by 8-inch cylinders made for the same sample of concrete.

· Mold and cure test specimens in accordance with ASTM C31/C31M, and test in accordance with ASTM C39/C39M for test cylinders. Immediately report results of all strength tests to the Contracting Officer.

· Maintain quality control charts for individual strength "tests", ("test" as defined in paragraph STRENGTH REQUIREMENTS) moving average of last 3 "tests" for strength, and moving average for range for the last 3 "tests" for each mixture. Provide charts similar to those found in ACI 214R.

Inspection Before Placing

Inspect foundations, construction joints, forms, and embedded items in sufficient time prior to each concrete placement in order to certify too the

Contracting Officer/COR that they are ready to receive concrete. Report the results of each inspection in writing.

Placing

The placing foreman must supervise placing operations, determine that the correct quality of concrete or grout is placed in each location as specified and as directed by the Contracting Officer/COR, and be responsible for measuring and recording concrete temperatures and ambient temperatures hourly during placing operations, weather conditions, time of placement, volume placed, and method of placement. The placing foreman must not permit batching and placing to begin until it has been verified that an adequate number of vibrators in working order and with competent operators are available. Do not continue placing if any pile of concrete is inadequately consolidated. If any batch of concrete fails to meet the temperature requirements, take immediate steps to improve temperature controls.

· Mixer Uniformity

Stationary Mixers

Prior to the start of concrete placing and once every 6 months when concrete is being placed, or once for every 60,000 cubic meters 75,000 cubic yards of concrete placed whichever results in the shortest time interval, determine uniformity of concrete mixing in accordance with

ASTM C94/C94M.

· Truck Mixers

Prior to the start of concrete placing and at least once every 6 months when concrete is being placed, determine uniformity of concrete mixing in accordance with ASTM C94/C94M. Select the truck mixers randomly for testing. When satisfactory performance is found in one truck mixer, the performance of mixers of substantially the same design and condition of the blades may be regarded as satisfactory.

· Mixer Uniformity Corrective Action

When a mixer fails to meet mixer uniformity requirements, either increase the mixing time, change the batching sequence, reduce the batch size, or adjust the mixer until compliance is achieved.

· Reports

Report all results of tests or inspections conducted, informally as they are completed and in writing daily. Prepare a weekly report for the updating of control charts covering the entire period from the start of the construction season through the current week. During periods of cold-weather protection, prepare daily reports of pertinent temperatures.
