Problems solved by technology

[0002] At present, the existing defects of concrete hollow block bricks used for construction are: 1. Due to the use of concrete materials, even hollow bricks are not light in weight, and the bearing capacity of the foundation is required to be high; 2. The purpose of hollow bricks is to reduce weight , which makes the thickness of the brick wall thinner, and there is no reinforcement, so the brick has low toughness, low strength, and is easy to break
[0003] In rural areas, the tendons of grain and oil crops such as rape stalks and rice straw are treated as waste, and most of the treatment methods are incineration. This situation not only does not make rational use of resources, but also causes serious environmental pollution.

Abstract

Rape stalk, rice straw and other straw of crop and common concrete material are produced into light concrete hollow block. The production process includes crushing crop straw in crusher; mixing the crushed straw and common concrete material via stirring; pressing the mixture in a brick making machine; and drying in the air. The present invention aims at reducing the weight of the concrete block, raising the toughness and strength of the block and reducing the environmental pollution caused by waste crop straw.

Description

Technical field: [0001] The invention relates to a method for manufacturing concrete block bricks, in particular to a method for manufacturing lightweight concrete hollow block bricks. Background technique: [0002] At present, the existing defects of concrete hollow block bricks used for construction are: 1. Due to the use of concrete materials, even hollow bricks are not light in weight, and the requirements for the bearing capacity of the foundation are relatively high; 2. The purpose of hollow bricks is to reduce weight , which makes the thickness of the brick wall thinner, and there is no reinforcement, so the brick has low toughness, low strength and is easy to break. [0003] In rural areas, tendons of grain and oil crops such as rape stalks and rice straw are treated as waste, and most of the treatment methods are incineration. This situation not only does not make rational use of resources, but also causes serious environmental pollution. Invention content: [00...
