Colored bamboo fiber coal gangue brick

Abstract

The invention relates to a colored bamboo fiber coal gangue brick. The colored bamboo fiber coal gangue brick comprises the following components in parts by weight: 30-40 parts of coal gangue, 13-18 parts of a construction waste regenerated fine aggregate, 10-15 parts of cement, 5-11 parts of lime powder, 2-5 parts of bamboo fibers, 2-9 parts of an activator, 2-5 parts of rubber powder and 0.1-5 parts of pigments. By making full use of waste rubber powder, industrial wastes and construction waste, resources and lands can be effectively saved, waste materials are consumed, and the colored bamboo fiber coal gangue brick has good economical benefit and sustained development is facilitated. By adding the bamboo fibers, the strength and density of the coal gangue brick can be obviously improved; by adding the waste rubber powder, the coal gangue brick has good waterproofness and insulating property; by adding an inorganic oxide into the coal gangue brick as the pigment of the coal gangue brick, the coal gangue brick is firmly colored and has very high practical value.

Description

technical field [0001] The invention relates to a coal gangue brick, in particular to a colored bamboo fiber gangue brick, which belongs to the technical field of building materials. Background technique [0002] With the development of the country's economy, the amount of bricks used in construction is increasing. Coal gangue bricks are a new type of wall material to replace clay bricks. The production cost of coal gangue bricks is lower than that of ordinary clay bricks. The main component of coal gangue bricks is coal gangue, which is the waste generated during the production and processing of coal. It is one of the industrial wastes with the largest stock in my country. A large amount of coal gangue has accumulated in many areas of our country, occupying land and causing serious environmental pollution. Using coal gangue to make bricks can not only save energy, but also protect the land and the environment. [0003] Although coal gangue brick is a kind of building mat...
