摘要

PURPOSE:To provide a hydraulic composition giving mortar or concrete having a large initial strength and a large long-term strength by employing blast furnace glassy slag fine powder having a specific particle distribution. CONSTITUTION:A hydraulic composition comprises 20-80wt.% of blast furnace glassy fine powder comprising =90wt.% of particles passing through a sieve having a size of 10mum, 50-80wt.% of the particles passing through a sieve having a size of 5mum and 10-20wt.% of the particles passing through a sieve having a size of 1mum as shown in the oblique line region of the figure, 80-20wt.% of a cement and, if necessary, gypsum in an amount of =15 pts.wt. per 100 pts.wt. of the composition. The composition is mixed with water in a water/binder weight ratio of 0.3-0.5, when used as a binder. When the composition is used for the curing of the mortar or concrete, the mortar or concrete is aged under a saturated steam condition of 40-80 deg.C for 2-24hr in order to improve the compression strength of the mortar or concrete.
