-- Method and computer program for prediction of compreesive strength and optimal combination of cement-fly ash-limestone powder concrete

摘要

The present invention relates to a computer program for developing a hydration model, predicting compressive strength, and optimizing blending of cement-fly ash-limestone micropowder ternary concrete, and more specifically, to a method for predicting compressive strength and optimizing blending, and a computer program based on the method. More specifically, the ternary concrete is prepared by maintaining advantages of conventional binary concrete while compensating disadvantages of the same such that the ternary concrete has great potential. However, even though various studies are conducted on the ternary concrete, there are few studies carried out on properties of macro materials of the concrete and a microstructural relationship thereof. In particular, there is insufficient research conducted on a hydration reaction and expression of compressive strength of the ternary concrete such that there is a need to conduct more research on the related field. Meanwhile, since the compressive strength of concrete is influenced by various factors such as designed blending, it is not easy to mathematically model the compression strength of concrete, and the same applies to the ternary concrete. In consideration of improved properties of the ternary concrete compared with the conventional binary concrete, there is a growing need for a mathematical model and a program for predicting the compressive strength. Therefore, according to the above needs and requirements, the present invention proposes a hydration reaction model of the ternary concrete and an expression model of the concrete compressive strength based on the same. In addition, the present invention provides a program of automatically calculating the concrete compressive strength when the concrete blending or growing condition is inputted without any material experiment. Thus, it is possible to derive an optimum blending ratio of cement-fly ash-limestone micropowder ternary concrete by using the program.
