Title:
METHOD FOR PRODUCTION OF THREE-DIMENSIONAL GRC PANEL
Document Type and Number:
Japanese Patent JP3759597
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To efficiently mass-produce a three-dimensional platy GRC panel having projections or recesses in its surface and inner face by surely preventing the bounce of aggregate on a molded face when spraying a mortar to a molding mold.
SOLUTION: The production method for the three-dimensional GRC (glass reinforced concrete) platy panel having projections or recesses in its surface and inner face comprises spraying, together with glass fibers, the mortar being a mixture of cement, aggregate and water in the inner face of a three-dimensionally moldable mold from the nozzles under the air pressure of 1-3 kgf/cm2, and hardening. In this case, it is preferable to use the lightweight aggregate having the weight per liter of 0.03-0.6 kg and a particle size of ≤3 mm, and also is preferable to use the mortar containing the aggregate in an amount of 8-15 wt% based on the cement.
