Abstract

     

This research investigated the unconfined compressive strength and indirect tensile strength of crushed rock-cement waste improved with Portland cement type I (PC) and hydraulic cement (HC). Binder contents of 1, 3, and 5% by weight of dry soil were used. Unconfined compressive strength (UCS) and indirect tensile strength (ITS) of samples at a curing time of 7 days were evaluated. The test results showed that the UCS and ITS of crushed rock-cement waste improved with PC and HC increasing with binder content. The UCS and ITS of crushed rock-cement waste improved with PC were higher than those of samples with HC. The optimum cement content was 3% for PC and HC, which gave UCS samples that met strength requirements.
