DEVELOPMENT OF LIGHT WEIGHT CONCRETE BLOCKS USING WASTE POP AND GYPSUM BOARD
Buildings built of concrete reinforced have become more common over the past several decades due to the abundance of building materials, their low cost, and convenience of construction. Better design standards throughout the years have resulted in the production of more earthquake-resistant design constructions. The self-weight of reinforced structures is rather high. The live load that a reinforced concrete structure can take is relatively low in relation to the structure's dead weight. Replace heavy concrete with light concrete as a practical way to reduce the structure's dead mass and increase its load bearing capability. The main objective of the study was to compare the structural performance of grade M20 and M30 lightweight concrete to that of regular conventional concrete. Pop gypsum board was employed as a volumetric alternative for coarse material for producing light weight concrete examples for the inquiry. Casting of the light-weight concrete takes place in line with the requirements. A 150x150x150mm cube made from the best mix of light weight concrete was built in order to measure the compressive strength. From the investigation, it is evident that Plaster of Paris gypsum board replaced at 40% and 60% replacement levels offers the requisite strength to produce light-weight concrete blocks.
