摘要： An acid-resisting material obtained as a result of solidification of a mixture comprising the following components: an aqueous solution of a water-soluble silicate of an alkali metal selected from the group containing sodium and potassium, an inert filler, a hardening initiator and an organic additive taken in a quantity of 0.2-5.0 percent by weight of all components, selected from the group containing furfurol, furfurol-acetone monomer, furfuryl alcohol and the mixtures thereof. The said acid-resisting material features high resistivity to acid permeation which is independent of the duration of the exposure, as well as high resistance to water.

摘要： The rate of hardening of a portland cement mix is accelerated by the addition of a low molecular weight, water-soluble hydroxylated adduct formed by reacting melamine and an aldehyde. The adduct is employed in an amount within the range of from about 0.01% to about 1.00%, preferably from about 0.2% to about 0.8% by weight of cement. The water content of the cement mix for a given consistency tends to be lowered by the incorporation of the adduct, providing an additional advantage from the practice of the invention. The adduct may be employed as a concentrated solution in water and may be used in combination with known set accelerating agents and with set retarding agents where reduction in water content is desired without appreciable change in the rate of set of the cement mix.
摘要翻译：通过加入通过使三聚氰胺和醛反应形成的低分子量水溶性羟基化加合物来加速波特兰水泥混合物的硬化速率。加合物的使用量为水泥重量的约0.01％至约1.00％，优选约0.2％至约0.8％。给定稠度的水泥混合物的含水量倾向于通过加入加合物而降低，从本发明的实践提供了额外的优点。加合物可以用作水中的浓缩溶液，并且可以与已知的固化促进剂和用于减少水含量的凝固阻滞剂结合使用，而水泥混合物的组合速率没有明显变化。

摘要： Water-soluble salts of amines and formic acid are added to Portland cement compositions (e.g. concrete) to accelerate the setting time thereof. The additives exhibit a particular effectiveness for offsetting the set-retardation effect of waterreducing, set-retarding agents, (e.g. lignosulfonates) employed in Portland cement compositions.
