HYDRAULIC POWDERY COMPOSITION AND CURED PRODUCT THEREOF, AND METHOD FOR FORMING CURED PRODUCT
PROBLEM TO BE SOLVED: To provide a hydraulic powdery composition that can give a cured product having lightweight and excellent designability without need of a calcination process in the production and to provide a cured product of the composition.SOLUTION: The hydraulic powdery composition contains a magnesia-based binding material and a needle-like calcium metasilicate. The magnesia-based binding material uses magnesium oxide as a main raw material and preferably, further contains magnesium chloride and magnesium sulfate. The needle-like calcium silicate is preferably wollastonite. The cured product produced by adding water to the hydraulic powdery composition has surface glossiness and matte-toned luster and therefore is suitable for applications of a plastered wall, a tile and the like.SELECTED DRAWING: None
【課題】製造に焼成工程を必要とせず、軽量で意匠性に優れた硬化物を与えることができる水硬化型粉状組成物及びその硬化物を提供する。【解決手段】マグネシア系結合材と、針状メタケイ酸カルシウムとを含有することを特徴とする水硬化型粉状組成物。マグネシア系結合材は、酸化マグネシウムを主原料とし、さらに塩化マグネシウムと硫酸マグネシウムを含むことが好ましい。また、針状ケイ酸カルシウムは、ワラストナイトであることが好ましい。当該水硬化型粉状組成物に加水して得られる硬化物は、表面光沢性や、いぶし的艶を有するため、塗壁やタイル等の用途に適する。【選択図】なし
