摘要： Cement dispersing agents for self-compacting concrete of high flowability, comprising a water-soluble N-vinyl copolymer, prepared by copolymerizing (a) an N-vinyl-lactame or -amide with (b) a polyethylene glycol ester of maleic acid containing 6 to 240 moles of oxyethylene groups per molecule and (c) at least one monomer selected from among unsaturated dicarboxylic acids and (d) methallylsulfonic acid. When an aqueous solution of this copolymer is used as an admixture to freshly prepared concrete of even extremely low water-to-cement ratio, a high fluidity, a low decrease in flowability with the progression of time and a lack of segregation over time is attained.

摘要： A low-density, high-strength concrete composition that is both self-compacting and lightweight, with a low weight-fraction of aggregate to total dry raw materials, and a highly-homogenous distribution of a non-absorptive and closed-cell lightweight aggregate such as glass microspheres or copolymer polymer beads or a combination thereof, and the steps of providing the composition or components. Lightweight concretes formed therefrom have low density, high strength-to-weight ratios, and high R-value. The concrete has strength similar to that ordinarily found in structural lightweight concrete but at an oven-dried density as low as 40 lbs./cu.ft. The concrete, at the density ordinarily found in structural lightweight concrete, has a higher strength and, at the strength ordinarily found in structural lightweight concrete, a lower density. Such strength-to-density ratios range approximately from above 30 cu.ft/sq.in. to above 110 cu.ft/sq.in., with a 28-day compressive strength ranging from about 3400 to 8000 psi.

摘要： A composition, in the form of a concrete, cement paste, mortar or intermediate thereof, comprising one or more cementitious binder materials present in an amount ranging from 0.5% to 75% by weight of the composition, attapulgite present in an amount ranging from 0.01% to 1.00% by weight of the composition, and optionally water. Although subject to many uses, in some embodiments, the composition is suitable for applications in need or desire of self-consolidating concretes (SCCs), precast concrete, shotcrete, and the like. Although makeable by multiple methods, in some embodiments, the composition is made by mixing the component ingredients. In some embodiments, the composition has one or more properties chosen from superior aggregate suspension, eliminated segregation, improved workability, improved flowability, improved pumpability—or improved overall performance—of concretes.
