ARTIFICIAL AGGREGATE AND CEMENT CURING BODY
PROBLEM TO BE SOLVED: To provide an artificial aggregate which suppresses neutralization of a cement curing body and enhances strength development.SOLUTION: There is provided an aggregate which consists of 2CaO AlOSiOof 20-35 pts.mass and 12CaO 7AlOof 1-10 pts.mass based on 100 pts.mass of 2CaO SiOand preferably is one or more kind of burned article selected from industrial waste, general waste, contaminant and construction generated soil. There is provided a cement curing body containing the artificial aggregate, preferably containing fine aggregate and/or coarse aggregate with volume substitution rate of the artificial aggregate of 50 vol.% or more based on all fine aggregate and/or all coarse aggregate.SELECTED DRAWING: Figure 1
【課題】セメント質硬化体の中性化を抑制し、また強度発現性を向上させる人工骨材の提供。【解決手段】２ＣａＯ・ＳｉＯ２１００質量部に対し、２ＣａＯ・Ａｌ２Ｏ３・ＳｉＯ２を２０〜３５質量部、および１２ＣａＯ・７Ａｌ２Ｏ３を１〜１０質量部含む焼成物からなる骨材であり、好ましくは、産業廃棄物、一般廃棄物、汚染物、および建設発生土から選ばれる１種以上の焼成物である骨材。また、セメント質硬化体は前記人工骨材を含み、好ましくは、全細骨材および／または全粗骨材に対する、前記人工骨材の体積置換率が５０体積％以上である細骨材および／または粗骨材を含む、セメント質硬化体。【選択図】図１
