Conventional materials are considered to be major contributors to Green House Gas (GHG) emissions. New cost-effective technologies for housing are, therefore, a need of the hour. To make mass housing cost-effective in the shortest possible time, each of the housing components has to be optimized for cost and production time. The disposal of fly ash is posing a great threat to its disposal problem. There is a dire necessity for alternate materials replacing conventional costly materials with cost-effective and environmentally friendly materials making them energy efficient.

The technology and advantages of construction of cost-effective and energy-efficient construction using the developed Carbon Neutral Soil-Cement Fly Ash (SCF) blocks. Construction methods adopted were Arch foundation, Rat-Trap bond using SCF blocks for masonry, precast SCF block Lintel elements, and partially precast SCF Slab Panels for flooring/roofing. Overall Cost to the extent of 42% can be saved using this cost-effective construction technology over the conventional method. The energy of the building can be drastically brought down. 36.39 GJ (4.2T of CO2) for conventional construction to 9.51 GJ (1.33T of CO2) for cost-effective construction. Energy to the extent of 74% can be saved using this technology.
