Following steps to be followed before pouring Ready Mix\nConcrete(RCC)<\/strong><\/h3>\n\n\n\n

1) Transit trucks shall comply with the relevant code, with\nan agitating speed between 2 and 3 RPM and mixing speeds in the range of 10-20\nRPM.<\/p>\n\n\n\n

2) Before unloading of any truck at the site, the RMC supplier shall supply a certificate\/batch sheet (a computerized sheet) along with moisture correction for the concrete, mentioning proportions of all the ingredients, w\/c ratio, dosage of plasticizer and relevant admixtures etc. (please refer Specification for Supply of RMC). <\/p>\n\n\n\n

3) The maximum water cement ratio, as specified in the\napproved mix design shall not be exceeded.<\/p>\n\n\n\n

4) The information provided by RMC supplier shall be cross\nchecked at site, and in all cases slump shall be taken prior to concreting. The\naccuracy of the measuring equipment shall be within + 2 percent of the quantity\nof cement and mineral admixtures being measured and within + 3 percent of the\nquantity of aggregate, chemical admixture and water being measured.<\/p>\n\n\n\n

5) Concrete which needs to be pumped shall have workability\nbetween 120 to 150 mm or as specified when the transit mixer arrives. Any\nconcrete shall be designed for a minimum three hours retention\/open time. The\nworkability of the concrete shall be controlled on a continuous basis during\nproduction and any corrective action necessary shall be taken. No additional\nwater, other than the amount required to produce the specified grade of\nconcrete as per mix design, shall be added to the truck mixer drum before\ndischarge unless specifically requested and signed for by representative.\nRedosing or split dosing shall be allowed subject to the written permission of\ntrained technicians and Engineers . In any case, the total dose should not\nexceed the maximum dose of admixture declared by Supplier or recommended by\nAdmixture supplier.<\/p>\n\n\n\n

6) It shall be ensured that the retardation time achieved by\nthe use of admixtures does not exceed the time required for transit and actual\nplacement of concrete. This shall be achieved by checking the time of dispatch\nof transit mixer mentioned on challan. Any Concrete is being designed with the\nhelp of water reducing agents and retarders for a stipulated retention time. So\nthe concrete must be consumed within the same time as considered in design. Our\nall concrete mixes must be designed for 3 hours retention time, so concrete\nmust be consumed with in 3 Hours from the time of batching. If the workability\nof concrete is higher than desired workability and segregation & bleeding\nis observed, we should allow some time to elapse before discharge till\nworkability drops to the range of 120 to 150 mm. If workability is less, then\nredosing or split dosing shall be allowed but in any case, the total dose\nshould not exceed the maximum dose of admixture declared by Supplier of\nconcrete or recommended by Admixture supplier. We must avoid over dosing which\nmay cause delay in setting of concrete<\/p>\n\n\n\n

7) Temperature<\/g> of concrete at the time of pumping shall be less than 40 degree or as mutually agreed between engineer and Supplier of Concrete. <\/p>\n\n\n\n

8) The cohesiveness and mixing of the concrete should be\nchecked, there should be no lumps, bleeding or segregation in the concrete.<\/p>\n\n\n\n

9) During every day\u2019s concrete unit weight of concrete as specified in IS: 1199 shall be checked and compared with theoretical density of concrete (sum of weight of all ingredients). If any significant deviation is observed, it indicates corrective measures are required in Concrete Mix Design. Supplier of concrete shall be immediately informed as this variation may impact yield of concrete or desired properties of the concrete <\/p>\n\n\n\n

10) Concrete carrying pipes shall not be allowed to rest on top reinforcement which is likely to bend. Leakage of slurry from concrete pipeline should be checked and rectified. <\/p>\n\n\n\n

12) At high altitudes wind breakers shall be provided while\nconcreting.<\/p>\n","protected":false},"excerpt":{"rendered":"
