Abstract

PURPOSE:To obtain cement composition which is capable of forming a hydrated hardening body having high strength and free from deterioration due to the impurities and moisture by blending organic carboxylic acid with a specified inorganic component incorporating CaO and P2O5 or SiO2 and Na2O. CONSTITUTION:Organic/inorganic composite cement composition is obtained by incorporating an inorganic component described hereunder and an organic component which consists of organic carboxylic acid of <=100% for weight of the inorganic component. This inorganic component consists of powder of calcined substance at high temp. or melt of composite oxide contg. at least one member selected from CaO and P2O5 or SiO2 and Na2O. The inorganic incorporates at least one member selected from among alpha-Ca3(PO4)2, Ca5P2Si2O16, CaNaPO4 and Ca5Na2P4O16. These may be utilized as a state of a single substance, a mixture and a solid solution. Further, even when the compd. of Al, Pe, Mg and Na, etc., is incorporated in the inorganic component as the impurities, alpha-Ca3(PO4)2 contained in the inorganic component is not changed into beta-Ca3(PO4)2 and is made extremely stable in the limit wherein the amount of the compd. is 5wt.% or below of the whole body.
