A Study on properties of Concrete with Admixture as A Part of Cement or Fine Aggregate Part 1 Influence of admixture on compressive strength and drying shrinkage

摘要

About compressive strength, in the FA series, I seriesresulted in a decrease in strength as the substitution rateincreased, In the case of O series, in contrast to I series, thesubstitution rate increased and the strength tended toincrease. In the BS series, both I series and O series showedan increasing tendency with increasing substitution rate.About drying shrinkage, focusing on the FA series, theshrinkage rate was suppressed more than N at allsubstitution rates for both I series and O series. In addition,it was confirmed that the drying shrinkage tends to increaseif the substitution rate increases in I series. Focusing on theBS series, different from the FA series, it was confirmed thatthe shrinkage strain was suppressed as the substitution rateincreased for both I series and O series.
