Title:
CEMENT HARDENED BODY, METHOD FOR MANUFACTURING THE SAME, AND CEMENT COMPOSITION
Document Type and Number:
Japanese Patent JP2013014447
Kind Code:
A
Abstract:
To provide a cement hardened body capable of exhibiting high strength being hardly varied in local strength caused by degradation of fluidity of a cement composition whose water/binder ratio is 0.2 or less, and to provide a method for manufacturing the cement hardened body.
The cement hardened body is obtained by the steps, wherein the cement composition whose water/binder ratio is 0.2 or less on the basis of mass containing cement, aggregate, silica fume, and water is mixed to be put in a form, steam-curing step is processed at a temperature range of 70-100°C, then, heat-curing step is processed at 100-400°C.
