Abstract

The invention discloses a grinding waste perforated brick. The grinding waste perforated brick comprises, by weight, 10-25 parts of grinding wastes, 5-10 parts of basalt, 35-50 parts of furnace slag, 2-6 parts of manganese dioxide, 1-2 parts of borax, 2-4 parts of perlite, 10-20 parts of river sands, 1-5 parts of wood chips and 80-100 parts of water. The perforated brick has the advantages of scientific production technology, convenience in manufacturing, realization of waste utilization, low production cost, compactness, high strength, high hardness, good binding property, good wear resistance, no desertification, no cracks caused by rapid change of the temperature, no porcelain formation, no fragmentation, strong water absorption property, small shrinkage, wear, pressure, acid-alkali and ageing resisting functions and long service life.

Description

technical field

[0001] The invention belongs to the field of building material production, in particular to a porous brick made of grinding waste. Background technique

[0002] With the development of social economy, the construction industry has developed rapidly. Due to its small size, heavy weight, energy consumption, and environmental pollution, the clay solid brick is now prohibited and restricted by the state. The production and use of solid clay bricks is not allowed, Now the country is starting to promote the innovation of wall materials and the promotion of energy-saving buildings, and actively calls for the development and promotion of new building materials and products. With the introduction of preferential policies, other substitutes are now being used to burn bricks everywhere. However, the mainstream porous bricks currently on the market have considered strength, water absorption, wear resistance, pressure resistance and shock resistance, and are costly and ca...

Examples

Embodiment 1

[0039] A grinding waste porous brick described in this embodiment is composed of the following raw materials in parts by weight: 15 parts of grinding waste, 7 parts of basalt, 42 parts of slag, 4 parts of manganese dioxide, 2 parts of borax, and 3 parts of perlite , 16 parts of river sand, 3 parts of sawdust, and 90 parts of water.

[0040] The specific preparation steps of the above-mentioned grinding waste porous brick are as follows:
