Abstract

Compressive strength tests of concrete specimens were made using different components of steel slag. The pH values of concrete specimens in water was determined after certain curing. Relationship between compressive strength and hydration reaction in various components of steel slag was analyzed. Experimental results show that the optimal steel slag-mixing ratio is 20%. The compressive strength of concrete decreases as the steel slag-mixing ratio is over 30%. The pH values of concrete differs significantly with the steel slag mixed and carbonization time of concrete specimens mainly because steel slag contains a reasonable amount of the low-Fe-Al phase.

Key words： concrete; pH value; steel slag; strength
