Innovative Strategies for Eco Friendly Thermal Insulation Integrating Rice Straw and High Volume Fly Ash in Foamed Concrete

One of the most important challenges of future buildings is the reduction of energy consumptions in all their life phases, from construction to demolition. As a tropical country, India faces the serious issue of temperature rise and fall in most of the parts, which demands the need for thermal insulation in existing buildings. Insulation is a key component of sustainable building design. The present research work focuses on the development of a thermal insulation wall panel made from high volume fly ash foam concrete with the inclusion of rice straw. Utilization of straws in building materials can not only save the raw materials, reduce the cost, use scrap material and protect the environment but also can be of great significance to achieve sustainable development. The rice straw was collected from the nearby village locality and it was allowed to dry under the sun for 15 days in order to get rid of its moisture and serve to be easy for chopping. These dried rice straws were then chopped into tiny pieces of 10 mm long pieces and treated with NaOH. NaOH removes extractives, waxes, oil and amorphous constituents such as hemicellulose and lignin from fiber surfaces and thus increases the overall roughness of the surface. Strength and insulation properties are studied by conducting thermal, strength and durability study it was found that 1 is the optimum percentage of rice straw that can be added. In the second trial, foam concrete with 20 ,30 ,40 and 50 foam volume was used. Also, 50 by weight of cement was replaced with class F fly ash by completely eliminating sand. In the third trial, in addition to the 50 fly ash replacement a further replacement of 15 of cement with silica fume is done which results in an increase in strength, but a slight increase in thermal conductivity. Considering the increase in the number of ingredients foam concrete mix with cement to fly ash ratio 1 1, foam volume of 20 to 25 and rice straw content range from 0.5 to 1.5 by weight of cement was found to be optimum in terms of strength and functional property.
