Title: Production of cement having low separability and production of concrete having low separability
Inventor: CHIBA HIROHIDE
IPC: C04B28/04
Filed: 1992-08-19
Abstract: PURPOSE:To reduce an amount of a separation-reducing agent used in obtaining a compaction-free concrete. CONSTITUTION:In a method for producing concrete by kneading cement, aggregate, water reducing agent and water, cement having low separability obtained by mixing a cement clinker with a separation-reducing agent and crushing the mixture is used as the cement. Thereby, the separation-reducing agent can more effectively be dispersed into the cement and sufficient separation reducing effect can be obtained in a small amount of the separation reducing agent used. Since an amount of the separation reducing agent used is reduced, catching of air in kneading is reduced and a defoaming agent is made unnecessary. The producing method is free from problems of lowering of strength due to air entrainment. Since the producing method need not the addition of many kinds of admixtures and additives, blending and concrete kneading operation are reduced and the production is made inexpensive. Poor execution, oscillation in forming, noise pollution and shortage of man power are solved by making compaction unnecessary.
