PLACING METHOD OF HIGH STRENGTH CONCRETE HAVING FREEZING DAMAGE RESISTANCE

摘要

PROBLEM TO BE SOLVED: To provide a placing method of concrete capable of sufficiently improving freezing damage resistance of the concrete, without impairing strength of the concrete, when using high strength concrete of using fly-ash cement in a cold district.SOLUTION: A placing method of concrete executes a process of transporting and carrying in a fresh concrete material 1 including a cement material of including fly-ash, an aggregate and water to a concrete placing site S2 from a concrete manufacturing site S1, a process of providing placing fresh concrete 3 by adding and kneading a mousse-like foam mass 2 including a fine foam to the fresh concrete material 1 in carried-in concrete placing site S2 and a process of placing the placing fresh concrete 3 in a placing spot SP1 in the concrete placing site S2.SELECTED DRAWING: Figure 1
