Title:
CEMENT HARDENED BODY AND ITS PRODUCTION PROCESS
Document Type and Number:
Japanese Patent JP3683826
Kind Code:
B
Abstract:
PROBLEM TO BE SOLVED: To provide a cement hardened body which can be produced by a production process that involves mixing, as a substitute for cement, a large amount of incineration ash into cement, in a cement mix for forming a cement formed body, and also to provide the production process of the cement hardened body.
SOLUTION: The production process involves mixing a cement mix containing cement (C) and incineration ash (F), then forming the mixed cement mix into a cement formed body and hardening the cement formed body, wherein, in the cement mix, the ratio (F/(F+C)) of the content of the incineration ash (F) to the total content of the cement (C) and the incineration ash (F) is ≥10 mass %, also, the cement mix contains a fibrous reinforcing material in a 2-10 vol.% ratio of the fibrous reinforcing material to the mixture (F+C) of the incineration ash (F) and the cement (C), and further, in the cement mix, water- powder ratio (S) meets the relational expression 0≤(S-S0)≤5% (S0 is an optimum water content).
