Stimulus of agro-industrial waste to make eco-concrete-A review

摘要

Large amount of waste materials (fly ash, pond ash, rise husk ash (RHA), paper mill slag etc) are produced from various industries; create environmental problem along with depositional hazards. Utilizing rise husk ash as alternative material for construction will lead to gainful solution. RHA is a by-product material obtained from the combustion of rice husk which consists of non-crystalline silicon dioxide with high specific surface area. It is one of the pozzolanic materials that can be added to the cement for the better production of durable concrete and the reduction of the environmental impact of the cement industry. This paper provides an overview of the work carried out on the use of the RHA as partial replacement of cement in concrete. Criticalreview of investigations on mechanical properties, durability of the concrete are presented.
