Embodiment 1

[0018] In this embodiment 1, 35 parts of coal gangue, 15 parts of regenerated fine aggregate of construction waste, 10 parts of cement, and 8 parts of lime powder are put into a crushing and mixing crusher for crushing. 3 parts, 4 parts of activator, 3 parts of rubber powder, 2 parts of pigment, mixed with appropriate amount of water at the same time for mixing and stirring. It should be noted that wheel milling is required after stirring, which can ensure that the raw materials are fully mixed, and the mixture after wheel milling is sent to the aging warehouse for aging. After the aging is completed, the mixture is sent to a vacuum extruder to be extruded and then cut into codes. Then the cut body is dried and roasted to be processed into the required gangue bricks.

Embodiment 2-5

[0020] The preparation method of present embodiment 2-5 is identical with embodiment 1, and concrete component and content are as shown in table 1 below:

[0021] Table 1

[0022]

[0023] In embodiment 1-5, the bamboo fiber length can be any value between 5-15nm. The activator is a mixture of sodium sulfate and calcium sulfate, and the mass ratio of sodium sulfate and calcium sulfate is between 4-6:1. This activator can effectively accelerate the disintegration speed of coal gangue and significantly improve the reactivity of coal gangue. Reduce the sintering temperature of gangue bricks and save energy. The particle size of rubber powder is 0.3-2mm. The pigments are inorganic oxide pigments such as cobalt blue or iron red. Construction waste recycled fine aggregate is obtained by crushing and screening construction waste aggregate. Using construction waste recycled fine aggregate instead of traditional sand can effectively reuse construction waste and effectively save r...

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...
