Hollow fiber concrete sandwich stalk compression brick building block

Abstract

The invention provides a hollow fiber concrete sandwich stalk compression brick building block belonging to novel wall constructional material. The hollow fiber concrete building block is prepared from cement, fly ash, sand, crushed stone, water and polypropylene fiber according to the weight ratio of 1:0.6:2.4:2.8:0.57:0.0032; and the stalk compression brick is prepared from lime mortar, water and wheat stalk according to the weight ratio of 2:1:1:4, the pressure is the minimum pressure by which the pressure head can be completely pressed in a pressure bucket, and the building block is suitable to be applied to buildings in villages and small towns. The manufacturing process comprises that: two parts are manufactured independently to obtain a semi-finished product; and the stalk compression brick is filled in the concrete hollow building block to form the finished product. Tests prove that the building block has the advantages of high strength of wall, thermal insulation, heat preservation, sound insulation, and the like; moreover, a large amount of excessive stalk can be consumed, which also meets the requirement of the government on the development of circular economy, so that the hollow fiber concrete sandwich stalk compression brick building block is suitable to be popularized in rural areas.

Description

(1) Technical field [0001] The invention belongs to a new type of wall material. (2) Background technology [0002] my country is a large agricultural country, and produces a large amount of agricultural surplus-straw every year. Such as wheat straw, rice straw, corn, sorghum and cotton stalks. According to the latest statistics, there are 700 million tons of crop straw in the country every year, ranking first in the world. However, the utilization rate of these straws is still relatively low in our country. A large amount of straws are burned in the field, which not only causes serious air pollution, destroys the ecological environment, but also wastes valuable renewable resources. Hollow fiber concrete sandwich straw compressed brick block has the advantages of concrete hollow block and traditional pure straw block, and at the same time, it makes up for the shortcomings of the two, such as the insulation of hollow bricks and the strength of the wall. The building block is not o...
