Title:
PRODUCTION OF HYDRAULIC COMPOSITION USING GENERATED SOIL AND ADMIXTURE CONTAINING THE SAME
Document Type and Number:
Japanese Patent JP3172932
Kind Code:
B2
Abstract:
PURPOSE: To obtain a hydraulic composition which can sustain a suitable fluidity for hours with desired strength secured and cracking reduced by admixing a hydraulically solidifying agent, water and a masking agent to generated soil, further adding a dispersing agent thereto as they are stirred.
CONSTITUTION: After a hydraulically solidifying agent, water and a preadmixture having masking effect are added to generated soil, a post- admixture functioning as a dispersant is added and stirring is effected again to give this hydraulic composition. The hydraulically solidifying agent is, for example, portland cement, mixed cement, slab powder, gypsum mix, quick lime, slaked lime or particular fired dolomite. The pre-admixture for masking effect is, for example, an oxycarboxylic acid or a phosphonic acid derivative. The dispersing agent is, for example, an AE water-reducing agent, a high- performance water-reducing agent or a fluidizing agent.
