Problems solved by technology

[0003] In order to turn waste into treasure and turn harm into profit, fly ash has been studied and utilized in many fields. Fly ash has been widely used in construction, building materials, water conservancy, etc., especially with fly ash as the main material. The manufacture and production of unburned bricks, but currently unburned bricks made of fly ash as the main raw material have disadvantages such as poor freeze-thaw resistance, easy cracking, and brick weight.

Embodiment 1

[0016] Take 40kg of fly ash, 20kg of yellow sand, 25kg of ceramic powder, 15kg of cement, 0.1kg of rock sand crystal, 0.3kg of early strength agent, and 18kg of water, and add them to the mixer in sequence, and stir evenly; put the mixture in the brick press , pressed and formed into adobe; put the adobe under natural conditions for 1 hour until the adobe has a certain hardness, then send it into the autoclaved reaction kettle, place the adobe in a steam curing box for steam curing at 130°C for 4 hours; move the adobe to In the stacking shed, spray water evenly once a day for the first 2 days after stacking, and the finished product will be ready after 15 days. After inspection, the compressive strength of a single block is 12.5Mpa, and the flexural strength is 2.6Mpa.

Embodiment 2

[0018] Take 35kg of fly ash, 25kg of yellow sand, 20kg of ceramic powder, 20kg of cement, 0.2kg of rock sand crystal, 0.3kg of early strength agent, and 17kg of water, and add them to the mixer in sequence, and stir evenly; put the mixture in the brick press , pressed into adobe; put the adobe under natural conditions for 1 hour until the adobe has a certain hardness, then send it into the autoclave reaction kettle, place the adobe in a steam curing box for steam curing at 150°C for 3 hours; move the adobe to In the stacking shed, spray water evenly once a day for the first 2 days after stacking, and the finished product will be ready after 18 days. After inspection, the compressive strength of a single block is 12.3Mpa, and the flexural strength is 2.8Mpa.

Embodiment 3

[0020] Take 45kg of fly ash, 20kg of yellow sand, 20kg of ceramic powder, 15kg of cement, 0.2kg of rock sand crystal, 0.2kg of early strength agent, and 20kg of water, and add them to the mixer in sequence, and stir evenly; put the mixture in the brick press , pressed into adobe; put the adobe under natural conditions for 1.5 hours until the adobe has a certain hardness, then send it into the autoclaved reaction kettle, place the adobe in a steam curing box for steam curing at 160°C for 4 hours; move the adobe to In the stacking shed, spray water evenly once a day for the first 2 days after stacking, and the finished product will be ready after 20 days. After inspection, the compressive strength of a single block is 12.4Mpa, and the flexural strength is 2.9Mpa.

Abstract

The invention belongs to the technical field of building materials and in particular relates to a high ceramic powder content baking-free brick. The high ceramic powder content baking-free brick is characterized by being prepared from the following raw materials in parts by weight: 10 to 25 parts of ceramic powder, 30 to 50 parts of coal ash, 15 to 25 parts of yellow ground, 10 to 20 parts of cement, 0.1 to 0.3 part of rocky sand crystal, 0.1 to 0.3 part of early strength agent and 10 to 25 parts of water. The high ceramic powder content baking-free brick provided by the invention has the beneficial effects that the baking-free brick is prepared by taking the ceramic powder and coal ash as main raw materials, excellent chemical properties including wear resistance, decay resistance and stability of the ceramic powder are utilized, so that the inner structure of the baking-free brick is optimized, and the mechanical strength and stability of the baking-free brick are promoted. The baking-free brick is abundant in raw material, environment-friendly and free of pollution. The production process is simple, the investment is less, the cost is low, the benefit is good and the market competitiveness is strong.

Description

technical field [0001] The invention belongs to the technical field of building materials, and in particular relates to an unfired brick with high content of ceramic powder. Background technique [0002] Fly ash is the fine ash collected from the flue gas after coal combustion. Fly ash is the main solid waste discharged from coal-fired power plants. As the main solid waste discharged from coal-fired power plants, fly ash is also one of the largest industrial wastes in my country. With the development of the power industry, the discharge of fly ash from coal-fired power plants is increasing at a rate of 200 million tons per year. Increase. [0003] In order to turn waste into treasure and turn harm into profit, fly ash has been studied and utilized in many fields. Fly ash has been widely used in construction, building materials, water conservancy, etc., especially with fly ash as the main material. The manufacture and production of non-burning bricks, but currently the non-b...
