ACCELERATED CONCRETE STRENGTH STUDY

The results of the testing of concrete cylinders using three methods of accelerated curing i.e. boiling, constant temperature, and autogenous, indicate the all three methods can be used to predict the 28 day strength of concrete cylinders. The constant temperature and autogenous cure are the most practical methods for field application. The prediction equations to relate accelerated test specimens to standard must be developed for each materials source and for each class of concrete. Equations that included the concept of degree-hour maturity in their derivation appeared to offer some advantages over the least square regression analysis.
