摘要： A hydraulic cement is formed from a Class C fly ash, an alkali metal activator, and citric acid. Mortar and concrete compositions can be prepared with this hydraulic cement. The cement is particularly useful in producing mortar and concrete compositions that achieve high strengths in a short time, in particular, a mortar having a strength of at least 2500 psi in 24 hours, when cured at room temperature.

摘要： A blended hydraulic cement composition, curable at low temperatures, including temperatures below the freezing point of water, is composed of portland cement, slag, pozzolans including metakaolin, and admixtures including potassium carbonate and water reducing compositions. The cement is particularly useful in producing concrete compositions which achieve high strength in a brief period of time, and continue curing at ambient temperatures, and temperatures below the freezing point of water.

摘要： An early high-strength mineral polymer composition is formed of a polysialatesiloxo material obtained by adding a reactant mixture consisting of alumino-silicate oxide (Si.sub.2 O.sub.5,Al.sub.2 O.sub.2) with the aluminum cation in a four-fold coordination, strong alkalis such as sodium hydroxide and/or potassium hydroxide, water, and a sodium/potassium polysilicate solution; and from 15 to 26 parts, by weight, based upon the reactive mixture of the polysialatesiloxo polymer of ground blast furnace slag. Sufficient hardening for demolding is obtained in about 1 hour with this composition.

摘要： A cement with rapid strength gain having normal setting and volume change characteristics and its method of manufacture are disclosed. The cement has substantially all particles over 20 microns removed which advantageously results in higher early strength than normal portland cements. This is important in the prestress and precast concrete industry, and early high-strength cement is desirable for other uses such as patching or resurfacing highways and airport runways or in operations where early form removal is desired. The use of chlorides or other accelerators is unnecessary to obtain early high strengths; although, these and plasticizers can be used if desired.
摘要翻译： 公开了具有正常设定和体积变化特性的快速强度增益的水泥及其制造方法。 水泥基本上除去了大约20微米以上的所有颗粒，这有利地导致比普通硅酸盐水泥更高的早期强度。 这在预应力和预制混凝土工业中是重要的，早期高强度水泥对于其他用途（如修补或重铺公路和机场跑道）或需要早期拆除的作业是理想的。 使用氯化物或其他促进剂不需要获得早期的高强度; 尽管如果需要，可以使用这些和增塑剂。
