725.41 Mortar
Furnish mortar that is packaged and ready for use with the addition of water at the construction site. Ensure that each bag is stamped to show the latest date on which it may be used. Use mortar that consists of a cementitious system made up of:
(a) Natural aggregate, 3/8” maximum size, that meets the requirements specified in ASTM C 33 except for grading. Accomplish grading by blending sieve sizes to obtain the optimum density.
(b) Metallic aggregate free from nonferrous material, soluble alkaline compounds, and visible rust.
(c) Water reducers, workability agents, air-entraining agents, and catalysts.
Blend the materials to minimize bleeding, increase workability, resist exposure to freeze-thaw cycles and deicing salts, and prevent shrinkage within and at the perimeter of the patch, keyway, or other area to be filled.
Ensure that the minimum compressive strength of the mortar, as tested by ASTM C 109 for a 3” slump, is:
24-hour...........................................................................................35MPa (5000 psi) 7-day...............................................................................................60 MPa (8500 psi) 28-day.............................................................................................70 MPa (10,000 psi)
Ensure that the durability of the products when tested at 300 cycles, ASTM C 666, procedure A is:
Submerged in: DF (%)
Water 98
5% CaCl2 solution 95
5% NaCL solution 85
Ensure that the scaling resistance has a rating of 3, Moderate Scaling, after 50 cycles when tested in accordance with ASTM C 672.
Provide certification from the manufacturer that the product is compatible for work that is 1” or more in depth and more than 1” in width; and where the mixing, placing, and curing temperatures may range from 5O C to 30O C (40O F to 85O F).
Submit products proposed for use to the CO for approval, and accompany them with the manufacturer’s submittals substantiating all requirements in this section, including (1) graphs or charts showing the time, temperature, humidity, and curing requirements to achieve mortar strengths equal to the adjacent concrete; and (2) complete recommendations for storage, mixing, application, and curing procedures.
As specified as mortar on the contract plans, the following products meet the above requirements.
1. EMACO T425 or T430, manufactured by Chemrex.
2. RAPID SET DOT REPAIR MIX manufactured by CTS Cement Manufacturing Co.
3. SURE-GRIP HIGH PERFORMANCE GROUT (when extended with pea gravel) manufactured by Dayton Superior .
