Abstract: Due to quick urbanization, there is an immense interest for good quality building units. There is a degradation of environment due to generation of large amount of waste from different industries. Using this waste in constructive applications is a suitable alternative. Stabilized Mud Block (SMB) is an economical, energy efficient and eco friendly option for ordinary building block like Concrete block and burnt clay brick. Bagasse ash from Sugar factory, quarry dust and regionally available soil are used in the production of SMB. Sand content of the soil is increased by using quarry dust which alters the soil to make it suitable for block production.8% of cement by weight of soil is fixed as stabilizer by studying the literatures. Diverse mixes of stabilizers are used by substituting every percentage of cement by bagasse ash and replacing soil with ash. Tests on blocks such as density, compressive strength, water absorption, efflorescence, dimensionality, durability test and prism tests are conducted to access their fundamental properties and performance. The outcomes demonstrated that compressive strength and block density is diminished with each percentage substitution of cement by bagasse ash. Water absorption values are well within permissible limits. A stabilizer mix 4% cement+ 4%Baggase ash has fulfilled the necessities of Class 30 evaluation of SMB as given in IS: 1725-1982. Bagasse ash can be utilized as a supplementary stabilizer with cement in the production of SMB. Use of industrial waste and bagasse ash in SMB have numerous advantages like cost reduction and viable management of waste by reducing environmental impacts
