Mix proportion is process for mixing of cement, sand, coarse aggregate and water mainly in which it is required to keep balance of mixing ratio. The mix has been conducted for trial mix, control mix and blended mixes which are given below. Trial Mix.

Therefore, the corrected proportion of the volume of coarse aggregate for the water-cement ratio of 0.44. = 0.60+0.044. =0.644. For Pumpable Concrete, these values may be reduced by up to 10 percent (As per clause 5.5.2 of IS 10262:2019). Here, a 5 percent reduction is considered. Therefore, volume of coarse aggregate.

Apr 24, 2022Water/cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained, the strength of concrete at a given age depends on the w/c ratio. The lower the w/c ratio, the higher the concrete strength. All materials used for a design including the water quality should be to a high standard.
