Abstract: In order to compare the influence of three kinds of mineral admixtures (zeolite, nano-silica (NA) and rice husk ash (RHA)) on the setting and hardening process of styrene-butadiene copolymer/cement composite cementitious material, the three kinds of mineral admixtures was used as set conditioning material respectively. The influence of the mineral admixtures on the composite cementitious material was compared from setting time, early strength, hydration process, hydration products and so forth. The results showed that all the three kinds of mineral admixtures could promote the setting and hardening of the composite cementitious material. The setting time was shortened greatly and the early strength development was improved. But the set conditioning performance of the three kinds of mineral admixtures was different from each other. Moreover, there were some differences in setting conditioning mechanism: Zeolite had a great promoting effect on the formation of AFt, it not only promoted the hydration reaction of C3A, but also reacted with Ca(OH)2 to generate AFt and CSH gel; NA and RHA had a strong promoting effect on the hydration of C3S, it also reacted with Ca(OH)2 to generate CSH gel.
