A NEW METHOD FOR IMPROVING HIGH PERFORMANCE CONCRETE MIX PROPORTION

Abstract

High Performance Concrete has been used more and more broadly for engineering transportation structures in Vietnam such as bridges, tunnels, highways. This paper proposes a new method for improving high performance concrete mix proportion, which involves with the use of Visual Interactive Analysis Method (VIAM) together with a technique of spatial parameter survey. An integrated mathematical model was developed in order to optimize six criteria, which are the chlorine ion diffusion coefficient, per cubic meter cost, the amount of cement, fly ash, slag, chemical admixture. This model needs to satisfy with ten functional constraints and seven design variables. Finaly, twelve Pareto solutions have been found for the particular case determined by the experts in terms of criteria during the process of proportioning high - performance concrete mix.
