Document Type and Number:
Japanese Patent JP2587306
Kind Code:
B2
Abstract:
PURPOSE:To enable curing in an autoclave, to improve strength, workability and durability and to reduce weight by mixing a hydraulic material with specified modified vegetable fibers and water and carrying out hardening. CONSTITUTION:Vegetable fibers are immersed in an aq. soln. contg. inorg. compds. (e.g. BaCl2 and ammonium hydrogenphosphate) each forming a water insoluble inorg. compd. and the fibers are taken out and dried to obtain modified vegetable fibers with 10-200 pts.wt. water insoluble inorg. compds. fixed in the insides and on the surfaces of 100 pts.wt. oven-dry vegetable fibers. A hydraulic material is mixed with 0.5-30wt.% of the modified vegetable fibers, water is added and aggregate, a filler, an air entraining agent and a water-reducing agent are further added as required. They are kneaded, molded into a desired shape and hardened.
