Abstract: A concrete comprises in relative parts by weight: 100 of Portland cement; 0.25 to 9 of a defoamer; 0.001 to 6 of a surfactant; 0 to 230 of coarse gravel and/or fine gravel and/or shear enhancers; 0 to 85 of sand; 0 to 60 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size less than 15 micrometers; 0 to 80 of a particulate pozzolanic or non-pozzolanic material or a mixture thereof having a mean particle size between 15 to 88 micrometers; 0.3 to 18 of a water-reducing superplasticizer; 0 to 14 of polyethylene fibers; and 5 to 40 of water. An air mixing process using a tightly sealed mixing tool is used to thoroughly mix the constituents of the concrete before adding the water for curing. By adjusting relative parts in the composition, concretes of high and ultrahigh performance can be achieved efficiently.

Abstract: A new class of ultra-high performance concrete with very high strength and very high tensile ductility (High Strength High Ductility Concrete) is provided that represents the culmination of two high performance cement-based composite systems, namely those of very high strength, and those of very high tensile ductility into a single composite system. The integration of high strength and ductility has been attained via the adoption of micromechanical analysis and design of fiber reinforced brittle matrix composites. In doing so, the new High Strength High Ductility Concrete material dramatically increases the energy absorption capabilities of structural systems employing this material, making it a very good candidate material where hurricanes, earthquake, impact and blast loads are a concern.

Abstract: A concrete product is produced by providing red dune sand having a particle size of 45 microns or less and mixing the red dune sand with hydraulic cement in a ratio of about 30% of the cement being replaced by the red dune sand. The cement and red dune sand are then mixed with fine and course aggregate, water and a superplasticizer and cast after pouring into a mold cavity. Then within 24 hours of casting, the cast article is steam cured for 12 hours under atmospheric pressure, demolded and placed in an auto clave at 100% humidity. The temperature in the auto clave is raised to 180° C. within one to two hours and maintained at that temperature for 4 to 5 hours. The temperature also increases the pressure to about 10 bars. The pressure is released to reach atmospheric pressure within 20-30 minutes and the temperature reduced gradually, so that the article can be removed.

Abstract: Therefore, the problem to be solved by the present invention is to provide highly general purpose ultra high strength fiber-reinforced mortar or concrete that shows a higher fluidity (workability) at the fresh state, a higher bending strength with a less content of metal fiber by enhancing both the absolute value of the compressive strength of mortar -matrix excluding metal fiber and the ratio of the bending strength relative to the compressive strength simultaneously at the hardened state, and acceptability of fine aggregate being used in ordinary ready-mixed concrete. An ultra high strength fiber-reinforced cement composition is characterized in that it contains cement, silica fume, coal gasification fly ash, gypsum and metal fiber and that the mass ratio of silica fume : coal gasification fly ash is 95 through 50 portions: 5 through 50 portions. Ultra high strength fiber-reinforced mortar or concrete contains such a cement composition and fine aggregate. An ultra high strength cement additives is characterized in that it contains silica fume, coal gasification fly ash and gypsum as principal ingredients and the mass ratio of silica fume: coal gasification fly ash is 95 through 50 portions: 5 through 50 portions.
