摘要： An additive for concrete, mortar or grout comprises at least one admixture material in a compacted unit of selected amount, the unit having strength sufficient to maintain structural integrity during handling and storage, but having sufficient solubility or friability upon mechanical agitation within a wet mixing environment of a cementitious composition mixture to dissolve or fragment for uniform dispersal throughout the cementitious composition mixture. A process for preparing a cementitious mixture includes providing ingredients i) at least one cementitious composition, ii) at least one admixture material and iii) a liquid; wherein the admixture material comprises at least one compacted unit having strength sufficient to maintain structural integrity during handling and storage, but having sufficient solubility or friability upon mechanical agitation within a wet mixing environment of the cementitious mixture to dissolve or fragment for uniform dispersal throughout said cementitious mixture; combining ingredients i), ii) and iii) and mixing in any order to dissolve or fragment the compacted unit to substantially disperse the admixture material throughout the other ingredients.

摘要： Compositions and methods relating to cementitious compositions are provided. The use of a glucoheptonate in the alpha form to prolong the workability of cementitious compositions is provided. The alpha form of glucoheptonate (found to have properties superior to the beta form when used to retard the hydration of cementitious compositions) can be used in combination with a plasticizing resin, e.g. a naphthalenesulfonate/formaldehyde condensate resin, to prolong the workability of a cementitious composition, without unacceptably delaying green strength development. Also provided are mixtures of a glucoheptonate in the alpha form and a naphthalenesulfonate/formaldehyde condensate resin plasticizer.
摘要翻译：提供了与水泥组合物相关的组合物和方法。提供了使用α形式的葡庚糖酸酯来延长水泥组合物的可加工性。葡萄糖酸钠的α形式（发现具有优于β形式的性质，当用于阻止水泥质组合物的水化时）可与增塑树脂（例如，萘磺酸盐/甲醛缩合物树脂，以延长水泥组合物的可加工性，而不会不可接受地延缓生坯强度的发展。还提供了α形式的葡庚糖酸盐和萘磺酸盐/甲醛缩合物树脂增塑剂的混合物。
