WATER-CURABLE TYPE CALCIUM PHOSPHATE CEMENT COMPOSITION

摘要

PURPOSE:To realize the proper consistency and the superior operation performance in kneading by providing a specific cement composition and a curing liquid containing at least water-soluble polysaccharides. CONSTITUTION:A cement composition is prepared from the mixed powder consisting of alpha-type tertiary calcium phosphate and secondary calcium phosphate dihydrate and having a Ca/P molar ratio of 1.200-1.498 as main component, and the curing liquid for this composition is allowed to contain at least water-soluble polysaccharides. Accordingly, the proper consistency and the superior operation performance can be obtained in kneading. Further, even at a narrow place or a place having a complicate shape, charging can be carried out surely and compactly, and fluidity and wetting performance can be improved.
