摘要: This research is to study the effect of particle size fly ash on packing and pozzolanic reaction mortar when 20% used replace Portland cement type I. Both effects can be determined by using insoluble material which have almost same Normally, compressive strength contributed from hydration reaction, effect, reaction. For mixed with material, due effect. Thus, difference in between mortar. The results show that activity index depends median curing ages samples. At early ages, higher than 3 90 days, ashes 2.7 160 μm constant about 22% standard (STD). differences are 3%, 20%, 27%, respectively, at 3, 28, days.
