STUDY OF STABILISED SOIL BRICKS AND ITS COMPRESSIVE STRENGTH

This paper presents the comparative study of stabilized soil bricks and the influence of stabilizer on compressive strength of soil bricks. For the study, locally available brown colour soil is used for production of bricks of size 230x110x75mm. This paper discusses the results of test performed on soil like atterberg limit test, grain size analysis, hydrometer test, specific gravity test, compaction test. This brownish coloured soil contains less than 10% of clay, therefore 5% clay is mixed before using stabilizer. In this study ordinary Portland cement, Portland pozzolana cement and silica fume are used as stabilizer at 5%, 8% and 10% by weight of soil. The bricks of stabilized soil are manufactured by hydraulic press at constant pressure of 30KN. This soil has (79%) sand fraction and (20.9%) silt & clay. The dry compressive strength of bricks are determined for 7days & 28 days.
