To overcome the higher consumption of cement we have to use eco friendly materials or the green building materials. One of the green building material is stabilized mud block. Here we are conducting the experiment to check on the compressive strength using stabilizers like cement and lime with varied proportion, and to study the effect of water repellent admixture in reduction of water absorption of stabilized mud block.
Initially the procurement of materials is done. Then suitable basic tests were carried out for the materials such as soil, m-sand, cement and lime. The SEB is prepared for different proportions of cement and lime. The prepared blocks are then cured upto 28 days and then tested for compressive strength (7 days, 14 days and 28 days). Water absorption test is carried out by applying a coat of siloxane which is water repellent admixture. Results are then evaluated.

1.INTRODUCTION Earth is the most abundant building material available for various construction work. Local availability of earth makes its use advantageous and hence making mud block as one of the most energy efficient, cost effective and very reliable building material in general. It’s very much important to enhance the properties of traditional unbaked mud blocks. Looking towards this, the alteration was made to them by stabilizing the earth with stabilizers. It’s known that constructions with mud brick technology has been widely used in regions soil containing high silt and clay contents. Therefore this study aims to investigate the enhancing the properties of mud bricks after its stabilization with cement and lime which are the stabilizing agents. In this experiment the compressive strength and water absorption of stabilized mud block is investigated.
