Title:
CEMENT COMPOSITION FOR EMBEDMENT TYPE FRAME AND EMBEDMENT TYPE FRAME USING THE SAME
Document Type and Number:
Japanese Patent JP3358690
Kind Code:
B2
Abstract:
PURPOSE: To obtain an embedment type frame for concrete placement having high bending strength, low shrinkage on drying and excellent durability by using a specific cement compsn.
CONSTITUTION: This cement compsn. contains (A) b) 3 to 30 pts.wt. gypsum, c) 0.5 to 5 pts.wt. shrinkage decreasing agent and d) ≤5 pts.wt. high-performance water-reducing agent consisting essentially of any of a polyalkyl allyl sulfonate system, melamine formalin resin sulfonate system, arom. amino sulfonate system and polycarboxylate system in a) 100 pts.wt. cement and (B) contg. broad end metallic fibers having the fiber length of 1 to 60mm, a fiber width of 0.1 to 5mm and the broad parts at both ends of the fiber width of 1.5 to 10 times the fiber width at 0.5 to 5 pts.vol. in total 100 pts.vol. of the cement compsn. and aggregate. (C) The embedment type frame is produced by kneading the cement compsn. and ≤40 pts.wt. water and 100 to 500 pts.wt. aggregate for general concrete per 100 pts.wt. cement.
