Title:
POLYMER/ASPHALT-MODIFIED CEMENT MORTAR COMPOSITION
Document Type and Number:
Japanese Patent JP3263741
Kind Code:
B2
Abstract:
PURPOSE: To improve physical properties by mixing respectively by specified weight ratios an aggregate and polymer dispersion of specified weight ratio, and nonionic asphalt emulsion with a hydraulic cement.
CONSTITUTION: Aggregate of ≤25mm particle size is compounded by 340-420 pts.wt to 100 pts.wt. of hydraulic cement such as Portland cement, and then polymer dispersion (A) such as styrene-butadiene rubber, by 10-60 pts.wt. of solid content to the hydraulic cement, and nonionic asphalt emulsifier containing nonionic surfactant such as polyoxythylene alkylphenol ether by 5-60 pts.wt. of solid content are mixed with the mixing ration ((A)/(B)) satisfying 15/55 to 90/10. Thus, a polymer/asphalt-modified cement mortar compsn. having excellent physical properties after hardening can be obtd. Further if necessary, fiber reinforcing material such as glass fiber may be compounded.
