Embodiment Construction

[0015] A construction waste unburned brick or building block described in the embodiment of the present invention is made of the following raw materials: 30-57 kg of construction waste crushed material, 25-50 kg of coal gangue particles, 8-15 kg of cement, pulverized coal Ash 3-18 kg, strong silicon sealing and curing agent 0.01-0.025 kg and water 8-12 kg. The construction waste crushed material is the solid that has been screened, removed metal objects and crushed to a particle size below 1.5 mm, modified with a modifier at a mass ratio of 100:11, and then stacked and purified for 1-3 days For construction waste, the improving agent is made of the following raw materials in parts by weight: 15 parts of ferrous sulfate, 15 parts of magnesium sulfate, 70 parts of quicklime and 0.1 part of potassium permanganate. The cement is Portland cement, sulphoaluminate cement, glass fiber reinforced cement (GRC), self-stressing iron-aluminate cement or white cement, colored cement or magn...

Abstract

The invention relates to a building garbage baking-free brick or building block and a preparation method thereof. The building garbage baking-free brick or building block is prepared from the following raw materials in part by weight: 30 to 57 parts of building garbage broken materials, 25 to 50 parts of coal gangue particles, 8 to 15 parts of cement, 3 to 18 parts of fly ash, 0.01 to 0.025 part of hydroxy silicon sealing curing agent and 8 to 12 parts of water. The building garbage baking-free brick or building block has the advantages that solid waste resources such as building garbage, waste bricks and tiles and waste porcelain are screened, subjected to impurity removal and crushed, so that the building garbage is changed into building materials and prepared into hollow building blocks, wall plates, paving bricks, paving stones and the like of different specifications. The product has the characteristics of high strength, no pollution, freezing and thawing resistance, low cost and the like; and meanwhile, a large amount of building garbage can be consumed, energy consumption is low, efficiency is high, industrial production is realized, and contribution is made to clean cities.

Description

technical field [0001] The invention relates to the field of building decoration materials, in particular to a construction waste unburned brick or block and a preparation method thereof. Background technique [0002] In recent years, with the continuous development of the national economy, there has been an upsurge of urban renovation across the country, with "big demolition" and "big construction" everywhere, and the amount of construction waste is increasing rapidly. The disposal of construction waste has become a major problem in urban construction. Rapid digestion and comprehensive utilization of construction waste has become a top priority. [0003] At present, for construction waste, most cities in my country adopt the method of paddock landfill, which not only occupies a large amount of land, but also consumes manpower and material resources, and at the same time hides the hidden danger of secondary pollution. Therefore, to realize the reduction of construction was...
