AGENT FOR IMPROVING WORKABILITY OF CEMENT COMPOSITION AND WATER-REDUCING ADMIXTURE FOR CEMENT CONTAINING THE SAME

摘要

PPROBLEM TO BE SOLVED: To establish a method excellent in its simplicity and cost for improving a remarkable deterioration of workability of concrete, which is derived from a variation of quality of the used aggregate such as its particle diameter, particle size distribution, etc. PSOLUTION: The agent for improving workability essentially contains a polyalkyleneoxide derivative and/or a hydrocarbon derivative.
