Title:
HIGH STRENGTH POROUS CONCRETE STRUCTURE AND ITS PREPARATION
Document Type and Number:
Japanese Patent JP3469786
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a high strength porous concrete structure which can be suitably used for water-permeable pavements, water drainage pavements, sound insulating plates, soundproofing walls, acoustical sound absorbing blocks, blocks for cultivation of plants, blocks for river bed, matrixes for purification of water, matrixes for adsorption of gas, decorative plates for construction, fish-breeding grounds, blocks for fish-breeding grounds and blocks for proliferation of algae and a method for preparing it.
SOLUTION: A high strength porous concrete structure 1 wherein a form is formed by bringing the surface side of a porous concrete structure 6 prepd. by using rough aggregates 10 into contact with a thermoplastic material 8 and by pouring a mortar or a concrete contg. no rough aggregate into this form, a number of bulky parts 2 forming rough aggregate shapes on its surface are integrally constituted of a common concrete structure and gaps 3 formed among these bulky parts 2 are extended to the back face side of the bulky parts 2, is prepd.
