  2. Global Recycling RICE HUSK ASH • Rice Husk Ash (RHA) used as partial replacement for Ordinary Portland Cement (OPC) in concrete. • Compressive Strength test was carried out on hardened 150mm concrete cubes after at 1, 3, 7, 28, 45 & 56 days curing in water • The compressive strength of the hardened concrete also decreased with increasing OPC replacement with RHA. www.ricehuskash.org

  3. Global Recycling INTRODUCTION • Rice husk is an agricultural waste product which is produced in about millions of tons. Approximately, for 100 Kg of rice, 20 Kg of rice husk are obtained. Rice husks contain organic substances and 20% of inorganic material. • Physical characteristics and chemical composition of mineral admixtures can be fulfilled by burning Rice husk into rice ash. • Combustion of rice husk at controlled temperature produces RHA that has amorphous silica content and large surface area. www.ricehuskash.org

  5. Global Recycling Value of Rice Husk Ash (RHA) Rice Husk Ash (RHA) is a good pozzolan proved by numerous researchers. During mass concrete, as compared to OPC concrete, RHA is very effective in reducing the temperature of mass concrete. The use of Rice Husk Ash as partial replacement for Ordinary Portland Cement in concrete. Compressive strength of the concrete at different level of replacement of RHA with OPC is determined. www.ricehuskash.org
