Determination of soil shear strength is essential for engineering construction. Using rice husk ash (RHA) with cement in the a potential ground improvement technique that can reduce environmental problems and construction budget. In present study, ten combinations soil-RHA-cement were investigated to understand effects RHA on parameters soil. The admixtures prepared by taking 5%, 10%, 15% RHA, ...

This paper discusses the results of Cd, Pb and Ni immobilization using cement. Soil contamination levels were in the range 500 mg/kg to 5,000 rug/kg. and cement ratios were in the range 3% to 18%. The process was highly effective in minimizing the leaching of tested heavy metals. The measured leaching reduction results were as follows: 76% to more than 96% for Pb; 30% to more than 99% for Cd; a...

Soil improvement is commonly carried out in construction work with the aim of increasing bearing capacity / strength soil so that it can carry load will stand on it. The method often used stabilization addition materials. In this study, was Portland Cement. This research begins sampling and laboratory testing to determine physical mechanical properties soil, followed by making samples for Uncon...

The influence of peat soil environment (PSE) on the mechanical properties cement-soil in area around Dianchi Lake and Erhai Yunnan Province has attracted much attention. This study explores change law UCS PSE, provides guidance for development sustained usage foundation. paper discusses preparation samples by adding humic acid (HA) cement to cohesive with low organic matter content (blending me...
