JP2001058173A - Method for concrete solidification of paper refuse, waste plastic (containing vinyl chloride resin), fiber refuse, side-drain sludge and sewage sludge - Google Patents

Abstract

PROBLEM TO BE SOLVED: To reutilize paper refuse, fiber refuse, waste plastic (containing vinyl chloride resin), side-drain sludge, sewage sludge and the like as a civil engineering material and a building material by solidifying them by concrete. SOLUTION: Paper refuse, fiber refuse, waste plastic, side-drain sludge and sewage sludge are mixed with cement and a binder to be granulated. Incineration ash is mixed with sludge and paper refuse to be granulated. In order to increase the strength of granulated matter, ceramic refuse is crushed to be utilized in place of sand. Coal ash (cliker ash) is also used in the same way. Incineration ash, coal ash, sewage sludge, sludge, glass ceramic refuse and sedimented residue are granulated to be utilized as gravel or a road bed material. In order to obtain soundproof and sound-insulating effect, zeolite and pumice are mixed and, for the purpose of cleaning water and adsorbing gas in air and adjusting humidity, zeolite, diatomaceous clay and coal ash are mixed. A product is obtained by kneading, molding and drying.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a generalized waste plastic containing paper waste, fiber waste, gutter sludge, sewage sludge, and PVC discharged as general waste and industrial waste, solidified into concrete, landfill material, pavement, and the like. It is commercialized and reused as civil engineering materials such as blocks, gutters, U-shaped grooves, and rice fields.

[0002]

2. Description of the Related Art Conventionally, a method of solidifying concrete is reused by waste plastic.
Highway noise insulation plates, U-shaped grooves, lids, etc. are only commercialized and used, and their use is also limited. They are not generally used, and various types of gutter sludge and sewage sludge are used. Although there are prototypes, there are problems with the safety and strength of harmful substances, and at present the product has not been developed.

[0003]

[0008] Therefore, the destination of use of the manufactured product is limited, and it is a fact that it is difficult to sell and use the product.

[(Strength according to Japanese Industrial Standards)] has not been resolved,
The same applies to safety. The present invention has been made to solve those problems.

[0004]

A method for solving the problems will now be described. (A) A cement and a binder are mixed with paper waste, fiber waste, waste plastic, gutter sludge and sewage sludge and granulated. Sludge and paper waste are mixed with incinerated ash (pal green) and granulated. (B) In order to increase the strength, the same applies to coal ash (clinker ash), which is used as a substitute for sand by crushing ceramic waste into granules. (C) Incineration ash, coal ash, sewage sludge, sludge It can also be used to granulate glass porcelain waste and sediment and use it as gravel or as roadbed material. (D) Mix zeolite and pumice for soundproofing and silencing effects,
Mixing zeolite, diatomaceous earth, and coal ash is effective in purifying water quality, adsorbing gas in the air, and adjusting humidity. (E) Determine the mixing ratio sequence according to the purpose of use. (F) The commercialized concrete products have been confirmed to meet the Japanese Industrial Standards as strength and fireproofing materials. (G) Kneading and molding by any of the methods (a) to (c)
It can be commercialized by drying. (H) Therefore, the present invention can reuse paper waste, fiber waste, waste plastic, and sludge as stable building materials and civil engineering materials.

[0005]

Next, the operation of the present invention will be described.
By granulating waste plastics, sludge, etc., the granules serve as quarries and gravel, and clinker ash and pal green serve as substitutes for sand, increasing the strength. Also, zeolite, diatomaceous earth, coal ash (clinker (Assue) Since it is made into a product using the properties of pal green, there is no elution of harmful substances, and stable building materials and civil engineering materials can be produced.

[0006]

[Effect of the Invention] Therefore, the strength is increased by granulating waste, and stable, safe building materials and civil materials are made by using zeolite, diatomaceous earth, coal ash (clinker ash), and par green. Can be.
