Abstract: An ultra high-strength hydraulic cement composition contains a binder, fine aggregates, coarse aggregates, an antifoaming agent, water and a specified admixture and has a unit amount of the binder in the range of 480-1800 kg/m3. Water and the binder are contained at a ratio of 10-25% and the admixture is contained in the amount of 0.2-3.5 weight parts per 100 weight parts of the binder. The binder may be cement or a mixture of cement and a microscopic powder admixture. The admixture is one or more selected from reaction mixtures obtained by specified two processes and partially or completely neutralized substances obtained from such a reaction mixture through these two processes and also a specified third process. The specified two processes include initiating a radical copolymerization process of a radical polymerizable monomer mixture containing maleic anhydride and a monomer of a specified kind in a non-aqueous system in the presence of a non-aqueous radical initiator and stopping the radical copolymerization reaction in its midst while the inversion rate of polymerization is at a specified level by adding water to the reaction system to thereby obtain a reaction mixture. The specified third process is for partially or completely neutralizing the reaction mixture.

Abstract: Cementitious compositions and methods for making the compositions wherein the compositions include high volume of mineral admixtures such as fly ash and blast-furnace slag in combination with rice hull ash. In one embodiment, the cementitious composition is a blend of hydraulic cement, rice hull ash and a mineral addition selected from fly ash and blast-furnace slag. The cementitious compositions can advantageously have high early and 28-day compressive strength and a very low permeability rating.

Abstract: A method of producing green concrete, and particularly to green concrete with Portland cement (C), natural basaltic volcanic ash pozzolan (VA), and microsilica (MS). The green concrete described herein is a high-performance green concrete composition that partially substitutes Portland Cement (C) and can further include fine aggregates (FA) and coarse aggregates (CA), water (W), and a super plasticizer (SP). The green concrete described herein can be cured at ambient temperature and can have a better compressive strength and durability properties, and high shrinkage resistance as compared to conventional concrete and, as such, can be used for high performance applications.
