According to the abstract released by the Intellectual Property India: "The present invention relates to a concrete composition and method in the field of construction materials, wherein a binder system (100) is formulated by combining Ordinary Portland Cement (OPC) (101) with Rice Husk Ash (RHA) (102) at 10-20 wt.% and Silica Fume (SF) (103) at 5-15 wt.% of cement. A plurality of fine (104) and coarse aggregates (105) along with water (106) are added to form a homogeneous mixture. The binder system is pre-dry mixed in a blending unit, ensuring uniform distribution before incorporating aggregates and water, and the mixture is cast and mechanically compacted to expel entrapped air. The invention further contemplates controlled combustion for RHA production and methods for curing in high humidity, thereby enhancing hydration and resulting in improved concrete performance."
