Abstract:
In order to reveal the objective laws governing the strength properties of cement stabilization of crushed aggregate(CSCA), a laboratory study was undertaken to research the influence factors of unconfined compressive strength(UCS)of CSCA by using vibrating compacted specimen and static compacted specimen. The results show the UCS values of vibrating compacted specimen after 28 d of curing is 2.54 times of the one of static compacted specimen, which shows that the compacted specimen type has a strong influence on the specimen structure. It was also found that the UCS values increase with cement contents’ adding when cement mass ratio is less than 5%, the UCS values of CSCA of dense framework type can get up to 10% of the CSCA of suspended dense type. The compactness of specimen raises 1%, the ultimate UCS values of CSCA increase about 10%, the UCS values increase with the increasing of curing time and the UCS values after 28 d of curing that can get up to 75% of the ultimate UCS values. 10 tabs, 3 figs, 12 refs.
