Building brick and manufacturing method thereof

Abstract

The invention discloses a building brick and a manufacturing method thereof and belongs to the technical field of building materials. The building brick is prepared from the following components in parts by weight: 40-60 parts of expanded perlite, 25-35 parts of ceramic clay, 12-18 parts of quartz sand, 5-15 parts of cement, 5-15 parts of talcum powder, 4-8 parts of quick lime and 10-20 parts of water. The manufacturing method of the building brick comprises the following steps: (1) mixing and stirring the expanded perlite, the quartz sand, the cement, the talcum powder, the quick lime and thewater in parts by weight so as to obtain a slurry mixture A; (2) mixing and stirring the ceramic clay, the cement, the talcum powder, the quick lime and the water in parts by weight so as to obtain amixture B; (3) pouring the mixture A in a gap between an outer-layer baffle plate and a middle-layer baffle plate, pouring the mixture B in a gap between the middle-layer baffle plate and an inner-layer baffle plate, pulling out the middle-layer baffle plate, and further sufficiently pressing by using a pressing plate; 4) drying a building brick, molded by using a mold, on the clean ground in theair. The building brick made by using the manufacturing method is good in heat-preservation and thermal-insulation effect and good in fireproof function.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a bricklaying method and a manufacturing method thereof. Background technique [0002] Nowadays, with the rapid development of science and technology, the population has increased rapidly, and the real estate industry has obtained unprecedented development opportunities. Some housing and office buildings need to be built. Now because of the continuous increase in floor height, the requirements for building bricks are also getting higher and higher. . [0003] The compressive strength of today's building brickwork is generally around 20-25 MPa. For buildings with less than 20 floors, the compressive strength of this kind of building brickwork is within the safe range. If it exceeds 25 floors and above For buildings, the compressive strength of building bricks is required to be at least 30 MPa. Therefore, the existing building bricks cannot meet the architectural design...

Problems solved by technology

[0003] The compressive strength of today's building brickwork is generally around 20-25 MPa. For buildings with less than 20 floors, the compressive strength of this kind of building brickwork is within the safe range. If it exceeds 25 floors and above For buildings, the compressive strength of building bricks is required to be at least 30 MPa. Therefore, the existing building bricks cannot meet the architectural design requirements of high-rise buildings. If the existing ordinary building bricks are used forcibly, it will inevitably affect the safety of the building
