Mud block is a construction material made primarily from soil. Types of earth block include compressed earth block (CEB), compressed stabilized earth block (CSEB), and stabilized mud block (SMB). Stabilized mud block is a building material made primarily from damp soil compressed at high pressure to form blocks. If the blocks are stabilized a chemical binder such as Portland cement they are called stabilized mud block (SMB). Creating SMBs differs from rammed earth in that the latter uses a larger formwork in to which earth is poured and manually tamped down, creating larger forms such as a whole wall or more at one time rather than building blocks. SMB uses a mechanical press to form blocks out of an appropriate mix of fairly dry inorganic subsoil, binders and fibers. The compression strength of properly made SMB can meet or exceed that of typical cement or adobe brick. Soil as a building material is available in most areas of world. In developing countries like India, earth construction is economically the most efficient means for house construction with least demand of resources
