PURPOSE:To inhibit the bleeding of a material for a cement milk construction method without deteriorating the suitability to injection and development of strength by blending cement with potentially hydraulic powder of a specified particle size, alkali metal carbonate and sodium aluminate in a specified ratio. CONSTITUTION:This material for a cement milk construction method is composed of 10-90 pts.wt. cement, 90-10 pts.wt. potentially hydraulic powder of <=15mum particle size, 0.5-10 pts.wt. alkali metal carbonate and 0.5-10 pts.wt. sodium aluminate. The potentially hydraulic powder may be water granulated blast furnace slag, a rapidly cooled compsn. similar to the slag or fly ash. |
