PROPERLY COPING WITH THE LOW WATER-CEMENT RATIOS REQUIRED BY ACI 35OR-83

The article discusses the writing of the ACI Committee 350's code that when adopted, will make a 0.45 water-cement (w/c) ratio mandtory when designing concrete sanitary engineering structures. The reasons for the maximum cement content of 0.45 are discussed. Concrete with a w/c ratio of 0.45 will have a 28-day compression strength of 4,200 to 52,00 psi (29 to 35.9 MPa), i.e, its strength in tension will be in the range of 444 to 512 psi (3060 to 3,530 kPa). Experience has shown that this is what it takes for a successfully designed water-retention structure.
