Title:
SOIL PAVEMENT MATERIAL
Document Type and Number:
Japanese Patent JP2018109323
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a soil pavement material having quick-hardening properties, excellent frost damage resistance, excellent weed-proofing properties, and a small amount of hexavalent chromium elution, thereby solving such problems occurring when conventional cement-based solidifiers (hardening agents), magnesia-based solidifiers, and calcium aluminate-based slag are used, that hardening requires a long period of time and hardening does not occur at a low temperature resulting in frost damage, that there is a large amount of contraction resulting in cracking, and that a weed-proof effect is low resulting in a large amount of hexavalent chromium elution.SOLUTION: The present invention provides (1) a soil pavement material comprising alumina cement, a latent hydraulic material, and soil, (2) a soil pavement material described in (1) further comprising a calcium component, and (3) a soil pavement material described in (1) or (2) further comprising an alkaline metal component.SELECTED DRAWING: None
