Abstract

Building the buildings and other engineering structures on weak or soft soil is very risky because such soil is prone to different settlements due to its low shear resistance and high compreessibility. Improving some soil properties such as bearing capacity and shear resistance characteristics can be done by one of the methods of improvement, which is stabilization. In this article, the effect of cement on soil properties in the southeast region of Semnan was investigated. The main objective of this research is to investigate the effect of cement on the compressive strength of sandy clay with silty soil. The tests used in this research included compaction and unconfined compressive strength. Laboratory samples were prepared by static compaction method. The samples were made in 95% of the maximum dry unit mass in order to achieve the best density and with different percentages of cement (2, 4, 6, 8, 10). With increasing the cement from 2% to 8%, the unconfined compressive strength of the cement soil increases and adding more cement causes the unconfined compressive strength to decrease. With increasing the amount of cement from 2% to 8%, the elasticity coefficient increased with a low slope, but with the increase of cement up to 10%, the trend of changes was strongly increasing. Adding cement increases the maximum dry unit weight. By adding cement to the soil, its resistance increases; This increase in strength is a function of the percentage of cement used and the curing time. The results obtained from the soil elasticity coefficient indicate an increase in the brittleness of the soil mixed with cement, which increases with the increase in the percentage of cement used or the curing time. Adding cement changes the fracture of the samples from soft to brittle.
