Experimental Study on Stabilized Mud Blocks using Foundry Sand

India is one of the developing countries, mainly based on the production of good quality construction materials. Taking into consideration of good quality materials and all such reducible, reusable, and recyclable [3R] materials we can utilise as alternative materials. The natural resources what we are using in construction are in exhaust stage, so we have to adopt alternative material. It must be low cost and eco-friendly, good quality, low transportation cost. Cement industry cause environmental impact like ozone depletion, acid rain, global warming is a main problem we are facing. More than 60% of the pollution causing by vast producing by construction and industrial waste. We can adopt burnt brick replacing by stabilized mud block [SMB] by using locally available soil and it won’t need fuel for burning block so it won’t emit carbon dioxide so it is an eco-friendly masonry building material. Replacing river sand by green sand or Foundry sand as an alternative, avoiding the usage of cement by rice husk ash [RHA] we can completely replace. Because the production of one ton cement emits one ton carbon dioxide if we avoid the cement usage we will be able to reduce the impact on environment. Rice husk ash all so we get in Hassan so the low transportation cost it’s a cost effective material.
