Title:
水和硬化体
Document Type and Number:
Japanese Patent JP4088434
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a hydration cured body which does not give rise to the collapse by delayed expansion and the lack of early age strength development even if the coal ash produced from coal combustion plants of a pressurized fluidized bed type and a pulverized coal combustion type is used in a large amount. SOLUTION: This hydration cured body is formed by kneading the coal ash produced from the coal combustion plant of the pressurized fluidized bed type and fine powder of blast furnace slag with water. In such a case, fly ash is preferably added further to the coal ash and the fine powder of the blast furnace slag and the mixture is kneaded with the water and a curing hardener. The fly ash produced from the coal combustion plant of the pulverized coat combustion type is more preferable and steel making slag is added thereto for a more preferable result.
