Studies on soil stabilized hollow blocks using c & d waste
The production of conventional building materials frequently results in resource depletion, environmental problems, and health problems, due to Production of building materials using fossil fuels which causes global environmental problem like global warming. With the potential to have a considerable impact on both society and the environment, the building and construction sector is a key participant in sustainable development. Stabilized mud blocks show to be an energy efficient, affordable, and ecologically friendly building material with the growing concern of awareness regarding sustainable building materials and environmental issue. Currently, stabilized mud block technology is being used in India to build more than 25,000 houses. The usage of stabilized soil-based construction materials, such soil stabilized Hollow blocks, can have several benefits over conventional building materials, including increased strength and durability, less negative environmental effects, and reduced costs. When old buildings are demolished, solid trash is usually categorized as either industrial waste or construction and demolition (C&D) waste. Massive volumes of waste are generated in India alone, and virtually little of it is recycled. This C&D waste can be used instead of soil or quarry sand to adjust the qualities of stabilized soil. This study investigates the utilization of combined C&D waste and a stabilizing agent in soil sampling. The studies involve soil stabilized Hollow blocks using combined C&D waste to check the strength of the hollow blocks for different replacements and its water absorption. The materials required for the research were procured from locally available demolished buildings. Cylindrical samples were cast for various compositions using mortar to test 30–34 different ratios of mixed building and demolition waste with 9% cement content.
