MANUFACTURE OF CONCRETE PRODUCT

Japanese Patent JP3171549

B2

PROBLEM TO BE SOLVED: To provide a simple method for manufacturing concrete product which can be recycled by fixing a decorative material in an arbitrary design to the surface, forming uniform and smooth joint, and facilitating the releasing operation of joint forming material.
SOLUTION: The method for manufacturing the concrete product comprises the steps of disposing a decorative material on net-like support in a concrete form in which the support is disposed at a distance from the bottom in parallel with the bottom in the form, heating to melt joint forming thermoplastic material formed by using polymer blended material containing polymer organic material and low-molecular-weight material as main ingredients so that the content ratio of the organic material is smaller than that of the low-molecular- weight material and the organic material has a three-dimensional continuous net-like skeleton structure, casting it in the form, then curing the thermoplastic material, then placing concrete in the form, curing it until the placed concrete is cured to develop the desired strength, removing it from the form after the concrete is cured, and releasing the thermoplastic material adhered to the surface.
