    Abstract: Bonded aggregate compositions such as concrete, concrete repair products, high temperature refractories, high temperature insulation and fire resistant insulation are made from an aqueous solution of phosphoric acid and a separate, storable dry mixture of suitable aggregate, monocalcium phosphate, and calcium in the form of calcium aluminate cement or calcium oxide. The proportion of wet to dry constituents is variable so as to select the working time and strength of the aggregate composition, typically on the order of ten to fifteen minutes. The mixture of the preferred dry constituents, and the binder to be mixed with the aggregate to yield the preferred dry mixture, are also disclosed. The binder system is particularly advantageous in that the same set of binder constituents can readily be employed with a variety of aggregates, reducing the cost of providing a variety of aggregate compositions due to the ready availability of the raw materials and obviating the need to stock different binders for different aggregate compositions. Cost is additionally reduced through the use of less purified, and therefore less expensive constituents.

    Abstract: This study reports in vitro and in vivo properties of fluorapatite (FA)-forming calcium phosphate cements (CPCs). Experimental cements contained from (0 to 3.1) mass % of F, corresponding to presence of FA at levels of approximately (0 to 87) mass %. The crystallinity of the apatitic cement product increased greatly with the FA content. When implanted subcutaneously in rats, the in vivo resorption rate decreased significantly with increasing FA content. The cement with the highest FA content was not resorbed in soft tissue, making it biocompatible and bioinert CPC. These bioinert CPCs are candidates for use in useful applications where slow or no resorption of the implant is required to achieve the desired clinical outcome.

    Abstract translation: 本研究报道了磷灰石磷酸钙水泥（CPCs）的体外和体内性质。 实验水泥含有（0〜3.1）质量％的F，对应于存在大约（0〜87）质量％的FA。 磷灰石水泥产品的结晶度随FA含量大幅度增加。 当大鼠皮下植入时，体内吸收率随着FA含量的增加而显着降低。 FA含量最高的水泥在软组织中不被吸收，使其生物相容性和生物相容性。 这些生物素CPCs是用于需要植入物缓慢或不吸收以达到期望的临床结果的有用应用的候选者。

    Abstract translation: 粘结的骨料组合物如混凝土，混凝土修补产品，高温耐火材料，高温绝缘和耐火绝缘是由磷酸水溶液和适当的聚集体，磷酸一钙和钙的单独的，可储存的干混合物形成的 的铝酸钙水泥或氧化钙。 湿干组分的比例是可变的，以便选择聚集体组合物的工作时间和强度，通常为十至十五分钟。 还公开了优选的干组分的混合物和与聚集体混合以产生优选的干混合物的粘合剂。 粘合剂体系是特别有利的，因为相同组的粘合剂组分可以容易地与各种聚集体一起使用，由于原料的可用性而减少了提供各种聚集体组合物的成本，并且避免了对不同的聚集体的需求 用于不同聚集体组合物的粘合剂。 通过使用较少纯化，因此使用成本较低的成分，还可以降低成本。
