Title:
HYDRAULIC SYSTEM, PRODUCTION THEREOF, CURING METHOD, CURING CHAMBER AND PAINT
Document Type and Number:
Japanese Patent JPH03265555
Kind Code:
A
Abstract:

PURPOSE: To improve strength and water absorption resistance and to inhibit efflorescence by molding an unhardened hydraulic system contg. a lime-contg. aq. soln. and a specified reactive agent, curing and hardening the molded body.

CONSTITUTION: An unhardened waste hydraulic system such as cement sludge or waste fresh mortar is added to an unhardened hydraulic system contg. a lime-contg. aq. soln. such as an aq. Ca(OH)2 soln. or an efflorescent component leaching soln. based on the Ca(OH)2 soln. and a reactive agent reacting with an efflorescent component such as silica or stearic acid. Aggregate is further added as required and they are molded with a mold 1 to obtain a molded body 2. Hermetically sealing lids 4 are then fitted to both ends of the mold 1 with packing in-between, air is blown from a pressure pipe 5 with a valve 6 fixed in one of the lids 4 and the molded body 2 with the hollow part 7 kept under high pressure is cured.
