Use of Rice Straw Ash as Pozzolanic Material in Cement Mortar

Abstract: Abstract-In this paper an experimental study was made on the effects of using Rice Straw Ash (RSA) as a partial replacement of cement in mortar. Control specimens with ordinary Portland cement (OPC) was made and in other specimens cement were replaced with 5%, 10% and 15% of RSA by weight of cement. Locally available rice straw was burnt to ash in uncontrolled manner in the earthen oven used by the rural people for cooking purpose, which were used in this study. The setting times and compressive strength of th… Show more

“…In India, rice straw is the leading agro-residue produced [6]. The RSA (ash produced when the rice straw is burnt) can be reused as a pozzolanic supplementary material in cement due to its high silica (SiO 2 ) content [7, 8, 9, 10, 11, 12].…”

“…Few researchers in the past have observed the effects of RSA on the primary and mechanical properties of cement paste, mortar and concrete [8, 9, 10, 17, 18]. But the effect of RSA on the durability properties of concrete has not been addressed in the past.…”

“…Many authors have proposed various additives that have pozzolanic properties. Thus, the authors of [11,12] present data on the effect of ash from burning rice straw and maize, but these works do not explain the hydraulic activity of the resulting additive.…”

“…Cheap and green materials obtained from industrial waste and agricultural by-products can be used to gain success in reducing CO 2 and cost production in cement manufacturing [5]. Therefore, the development of the use of natural pozzolan from industrial waste and agricultural by-products to reduce material cost of construction is now more attractive in the world [6]. Some types of earth minerals and plant substances can be found in many places in the world as cheap sources of pozzolanic materials to produce cheap construction materials, but their utilization is still partially accomplished [7].…”
