---------------------------------------------------------------------***--------------------------------------------------------------------GGBS is a waste produced in blast furnace by quenching Abstract: The indiscriminate infrastructural growth is molten iron blast furnace slag immediately in water or leading to rapid environmental degradation. Sand, cement, stream to produce a glassy product that is then dried and coarse aggregate for manufacturing of bricks and used for large construction activities are energy intensive as well as grounded into product. It is a waste that is produced in blast causing environmental pollution during their entire life cycle. furnace and its disposal is a very big problem in recent days In order to quantify the energy and savings potential by because in these days lot of land is getting waste due to applying best available technologies like Stabilized mud blocks disposal. When we use this as a binder in concrete for engineering applications. Even though the strength of SMB construction we can produce high performance concrete and is less compared to cement blocks, we can use the SMB by cement. So we are trying to use this waste in production of stabilizing it by using cement, lime. But in this project we are stabilized mud blocks and so we can reduce the pollution trying stabilize the blocks by using waste materials like GGBS and Alccofines. In this study we are utilizing the behavior of causing by it into atmosphere. Stabilized Mud Block with alccofines and GGBS by conducting Alccofine 1203 is a slag based supplementary cementitious various tests like the compressive, water absorption and materials having ultra-fineness, low calcium silicate product weathering test. We can use the stabilized mud blocks for non with optimized particle size distribution. Due to ultrastructural elements as it meets the strength requirements as fineness it penetrates into tight joints, fissures and pore per IS codes. And these blocks are purely eco friendly as it is made up of waste materials. spaces which impart greater water tightness. Key Words: Stabilized mud blocks, compression strength, GGBS, Alccofines, Eco Friendly Materials. 2. MATERIALS USED
1. INTRODUCTION Earth as mud bricks has been used in the construction of shelters for thousands of years. Approximately 30% of the world’s population still lives in earthen structures. Compressed soil masonry blocks formed using moist soil compacted mechanically to improve physical characteristics have aimed popularity recently. Benefits of earth in this manner include improved strength and durability as compared to adobe while maintaining significantly low embodied energy levels than alternative materials. However problems arise from the materials low tensile strength, brittle behavior and deterioration in the presence of water. Stabilization by a hydraulic binder such as cement or lime or a combination of the two can significantly improve water resistance and strength to some extent. Also waste materials can be used as a stabilizer in the stabilized mud blocks. We have used materials like GGBS and alccofines as a stabilizer in this project. Theoretical models were also developed on composite soil blocks with these stabilizers subjected to shear.
