Concrete Strength Estimation Using the Maturity Method

Article Preview

Abstract:

Two methods are used to estimate the concrete strength based upon the maturity concept. The conclusion is that the apparent activation energy E value is key factor in the equivalent age method, larger value of E indicated that the age conversion factor versus temperature function is more nonlinear, and an increase in temperature results in a disproportionate increase in the age conversion factor. It is also shown that there is a unique relationship between maturity and relative strength (ratio of strength to limiting strength), and the relative strength method method-can be used in the prediction for the concrete strength.
