Engineering Characteristics of Rubber-modified and Styrene Acrylic-modified Cemented Soil
Abstract
Currently, the methods of improving soil properties are various and have been widely used. The purpose of this project was to investigate the properties of soil improved with rubber-modified Cemented Soil and styrene-acrylic modified Cemented composite. In this study, Quarry by-product as unstandardized materials under the requirements stipulated by Department of Highways were tested to improve soil properties by using the ratio of the mixture as follows: 2 % cement to soil weight; 50% water and rubber to 50 % soil weight; 50% water and styrene-acrylic to soil weight. Then, this study conducted two tests for comparison, namely: Compaction Protor Test , Unconfined Compression test and Capillary rise test. Curing period of the samples was 7 days. The testing results showed that Maximum Dry Density of styrene-acrylic modified cemented Soil were higher than those of rubber-modified cemented Soil. Unconfined Compressive Strength of styrene-acrylic modified cemented Soil was higher than rubber-modified cemented Soil. Capillary rise test of styrene-acrylic modified cemented Soil was higher than rubber-modified cemented Soil
