Experimental Study on Slag-Based Composite Admixture

Abstract:

Admixture is a new material used for high-performance concrete. It is mainly used to improve the construction property and service performance and the durability of the concrete. At present, admixture is mainly made of a single component such as the slag, fly ash, silica fume, or mixed with a small amount of plaster. Different admixtures have different effects on the concrete and they have both advantages and disadvantages separately. Based on the principle of “Strength Synergistic Effect” of the composite materials, if the different kinds of admixtures are mixed into the concrete with suitable proportion, the advantages can be developed and the disadvantages will be avoided. In this study, the wide sources of admixtures such as slag, fly ash and limestone are used in the composite tests to develop a new kind of composite admixture which uses the slag as main raw material and has better performance.
