Thermal conductivity of unfired earth bricks reinforced by agricultural wastes with cement and gypsum

摘要: Abstract Energy-efficiency of sustainable constructions and buildings are evaluated based upon the heating cooling demands, but also according to primary-energy demand, CO2 savings potential, ecological properties building materials. To meet increasingly rigorous requirements, demand for natural materials is growing rapidly. The research objective here presented study stabilize soils with straw fibres produce a composite, sustainable, non-toxic locally sourced material. material appropriateness was determined by establishing thermal conductivity selection unfired earth bricks that were identified as potential new an essential characteristic achieve required insulation level market success product. consist soil, cement, gypsum fibres. Straw applied fibre reinforcement bricks. Two types used: wheat barley straw. results indicated all investigated variants decreased increasing content while higher cement contents. They show reinforced exhibited highest values. addition positively improves both, static properties.
