Low Cost Housing Innovations in Construction (PDF)

Research Paper (postgraduate) from the year 2022 in the subject Engineering - Civil Engineering, grade: A, , language: English, abstract: Housing plays a crucial role in providing individuals and households with a dwelling, and it encompasses the housing industry, infrastructure, and housing market. Low-cost housing options are essential for individuals with limited financial resources, and housing assistance programs are commonly offered by governmental and non-profit organizations to support those unable to afford market-rate housing. Various types of affordable housing exist, including apartments, townhomes, and single-family homes, often designed for specific groups such as the elderly or individuals with disabilities. Natural materials like bamboo, earth, straw, fiber cement composites, lime mortar, surki mortar, mud, and grass are explored for low-cost housing construction. India, a significant bamboo producer, has 136 species of bamboo, making it a readily available material. Earth has been used as a building material for centuries, and compressed earth blocks and non-erodible mud plaster can address its limitations. Straw, a residual material from agriculture, particularly rice straw, with its high silica content, shows durability potential. Researchers have also shown interest in utilizing natural fibers from various plant sources as alternatives to conventional construction materials. Man-made materials like volcanic ash, aerocon panels, ferrocement, hollow blocks, rice husk panels, and reinforced concrete have been developed and utilized in construction. Precast construction materials, such as precast concrete panels, beams, and columns, offer advantages like rapid manufacturing, quality control, durability, and longevity. The study focuses on investigating a system of precast brick panels with partially precast reinforced concrete connections. The panels are cast using timber molds and affixed onto precast joints, reducing materials and costs compared to conventional reinforced concrete slabs. Overall, the study explores the utilization of natural and man-made materials for affordable housing construction, considering their availability, durability, and cost-effectiveness.
