SIX STANDARD 6_INCH COMPRESSION CYLINDERS, 3 TO BE TESTED IN 7 DAYS AND 3 AT 28 DAYS, SHALL BE MADE WITH THE PROPORTIONING AND MATERIALS PROPOSED TO BE USED FOR EACH OF THE PRINCIPAL MIXES REQUIRED FOR THE WORK. THE SLUMP SHALL NOT BE LESS THAN THE GREATEST SLUMP EXPECTED TO BE USED IN THE STRUCTURE FOR EACH OF THE MIXES. THE TESTS MADE ON THE AGGREGATES, AS REQUIRED ABOVE, MAY BE MADE A PART OF THESE TESTS, IF SUITABLY REFERENCED ON THE REPORTS, WHICH SHALL BE ISSUED FOR 7 AND 28 DAY TESTS. THESE TESTS SHALL BE REPEATED, IF NECESSARY, BECAUSE OF CHANGE IN MATERIAL OR UNSATISFACTORY RESULTS. THE ADVANCE TESTING MAY BE WAIVED AT THE REQUEST OF THE CONTRACTOR AND WITH THE ENGINEER'S APPROVAL IF THE CONCRETE IS BEING PRODUCED BY AN ESTABLISHED READY_MIX PLANT WITH SUITABLE RECORDS OF MIXES AND TESTING AND IF THE PLANT CERTIFIES THAT IT WILL CONTINUE TO USE THE SAME MATERIALS INVOLVED IN THE RECORDED TESTING. DURING THE PROGRESS OF THE WORK, AND FOR EACH DIFFERENT MIX OF CONCRETE, A SET OF FOUR STANDARD 4 OR 6 INCH CONCRETE CYLINDERS SHALL BE MADE AND TESTED FOR EACH AND EVERY DAY'S OPERATION (OR 8_HOUR SHIFT) WHERE MORE THAN 5 CUBIC YARDS OF CONCRETE ARE PLACED. MAKE AN ADDITIONAL SET OF THREE CYLINDERS FOR EACH ADDITIONAL 50 CUBIC YARDS OF CONCRETE WHERE MORE THAN 50 CUBIC YARDS ARE PLACED IN ONE DAY FOR 8_HOUR SHIFT). THE CONTRACTOR SHALL BE RESPONSIBLE FOR SEEING THAT THESE CYLINDERS ARE MADE; CAST THE CYLINDERS IF TESTING LABORATORY PERSONNEL ARE NOT AVAILABLE. THE CYLINDERS OF EACH SET SHALL BE MOLDED FROM THE SAME SAMPLE OF CONCRETE AND TESTED, ONE AT 7 DAYS AND TWO AT 28 DAYS, AND ONE CYLINDER AT RESERVE. IF HIGH_EARLY STRENGTH CEMENT IS USED, THEN THE TESTS SHALL BE MADE AT 3 AND 7 DAYS INSTEAD OF AT 7 AND 28 DAY. ALSO, FROM EACH SAMPLE OF CONCRETE USED FOR TEST CYLINDERS, MAKE ONE SLUMP TEST IN ACCORDANCE WITH ASTM C143, ONE TEMPERATURE OF CONCRETE TEST IN ACCORDANCE WITH ASTM C1064, AND MAKE ONE ENTRAINED AIR CONTENT TEST IN ACCORDANCE WITH ASTM C231.

DO NOT USE ALUMINUM PIPES TO CONVEY CONCRETE. CONCRETE SHALL NOT BE DROPPED OVER 4 FEET THROUGH

SPACE. IT SHALL NOT BE DEPOSITED IN

LARGE QUANTITIES AT ONE PLACE AND BE PERMITTED TO RUN OR TO BE WORKED ANY CONSIDERABLE DISTANCE, BUT SHALL BE DEPOSITED IN ITS FINAL POSITION

AS NEARLY AS PRACTICABLE.

THE COARSE AGGREGATE SHALL BE WORKED BACK FROM THE FORMS WITH A SUITABLE TOOL SO AS TO BRING A FULL SURFACE OF MORTAR AGAINST THE FORM, WITHOUT THE FORMATION OF EXCESSIVE SURFACE VOIDS. ALL CONCRETE SHALL BE CONSOLIDATED BY MECHANICAL VIBRATION AUGMENTED AS NECESSARY BY SPADING, RODDING, OR FORKING SO THAT THE CONCRETE IS THOROUGHLY WORKED AROUND THE REINFORCEMENT, AROUND EMBEDDED ITEMS, AND INTO CORNERS OF FORMS, ELIMINATING ALL AIR OR STONE POCKETS WHICH MAY CAUSE HONEYCOMBING, PITTING, OR PLANES OF WEAKNESS. MECHANICAL VIBRATORS SHALL HAVE A MINIMUM FREQUENCY OF 7,000 REVOLUTIONS PER MINUTE AND SHALL BE OPERATED BY COMPETENT WORKMEN.
