Analysis of the Influence of Long Curing Age on the Compressive Strength of Plastic Concrete

Plastic concrete is a composite material between the normal concrete and clay, with its characteristics of long curing age and slowed growth of strength. hi this paper, the mathematical models of relationship between compressive strength (curing age of 540 days) and curing age (28 and 90 days) are established on the basis of multitudinous of tests. Comparing the value obtained by calculating model with experimental value, we find that they have well consistency. The establishment of these models provide the basis for making plastic concrete standard procedures and carrying out numerical analysis, and they also offer reference for engineering application of plastic concrete.
