Problems solved by technology

[0002] In the past, civil buildings in our country have always been dominated by brick-concrete structures. The brick-concrete structure uses a huge amount of bricks, which consumes a lot of soil for farming and the process of firing clay bricks consumes a lot of energy, which has a negative impact on the environment.
In addition, solid clay bricks have poor thermal insulation performance, which greatly increases the annual heating energy consumption

Embodiment 1

[0016] A kind of anti-seismic light aggregate concrete described in this embodiment, the raw materials include by weight: 120 parts of cement, 2 parts of rubber silk treated with interface agent, 30 parts of river mud, 4 parts of superfine silica powder, 150 parts of sand, 0.5 parts of thickener, 250 parts of water.

[0017] Its preparation method comprises the following steps:

[0018] (1) After mixing the rubber thread treated with the interface agent and the superfine silica powder, heat it to 140°C, take it out, cool it and roll it into powder;

[0019] (2) Put the mixture of step (1), one-third of the water and the thickener into the mixing tank and stir for 15 minutes;

[0020] (3) Put cement, river mud, sand and the remaining water into the mixing tank and mix for 18 minutes;

[0021] (4) Transport the uniformly mixed lightweight concrete to the site or precast workshop for pouring.

[0024] Its preparation method comprises the following steps:

[0025] (1) After mixing the rubber thread treated with the interface agent and the superfine silica powder, heat it to 150°C, take it out, cool it and roll it into powder;

[0026] (2) Put the mixture of step (1), one-third of the water and the thickener into the mixing tank and stir for 10 minutes;

[0027] (3) Put the cement, river mud, sand and the remaining water into the mixing tank and mix for 20 minutes;

[0028] (4) Transport the uniformly mixed lightweight concrete to the site or precast workshop for pouring.

Embodiment 3

[0030] An anti-seismic lightweight aggregate concrete, raw materials include: 150 parts of cement, 1 part of rubber silk treated with an interface agent, 40 parts of river mud, 2 parts of superfine silicon dioxide powder, 200 parts of sand, thickening 0.3 parts of agent, 300 parts of water.

[0031] Its preparation method comprises the following steps:

[0032] (1) After mixing the rubber thread treated with the interface agent and the superfine silica powder, heat it to 135°C, take it out, cool it and roll it into powder;

[0033] (2) Put the mixture of step (1), one-third of the water and the thickener into the mixing tank and stir for 20 minutes;

[0034] (3) Put the cement, river mud, sand and the remaining water into the mixing tank and mix for 15 minutes;

[0035] (4) Transport the uniformly mixed lightweight concrete to the site or precast workshop for pouring.

Abstract

The invention discloses shock-resistant type light aggregate concrete. The shock-resistant type light aggregate concrete comprises, by weight, 100-150 parts of cement, 1-3 parts of rubber threads treated by interface agents, 20-40 parts of river mud, 2-5 parts of silicon dioxide ultrafine powder, 100-200 parts of sand, 0.3-0.8 part of thickening agents and 200-300 parts of water. The shock-resistant type light aggregate concrete has the advantages that raw materials for the shock-resistant type light aggregate concrete are carefully selected, and methods for preparing the shock-resistant typelight aggregate concrete are scientific; silicon dioxide is hollowed out after the rubber threads and the silicon dioxide ultrafine powder are mixed with one another and are heated, the rubber threadsare partially stored in silicon dioxide particles and partially wrap the silicon dioxide particles, accordingly, shock energy transfer can be effectively blocked and reduced in a layered manner, heatcan be preserved, and the shock-resistant type light aggregate concrete is high in bearing capacity and low in cost and is structurally light.

Description

technical field [0001] The invention belongs to the field of concrete building materials, and in particular relates to an anti-seismic light aggregate concrete. Background technique [0002] In the past, civil buildings in my country have always been dominated by brick-concrete structures. The brick-concrete structure uses a huge amount of bricks, uses up a lot of soil for farming, and the process of firing clay bricks consumes a lot of energy, which has a negative impact on the environment. In addition, solid clay bricks have poor thermal insulation performance, which greatly increases the annual heating energy consumption. With the continuous development and progress of society, the development direction of building modernization is low cost, heat preservation, earthquake resistance, and long service life. The frequently used lightweight concrete has its application fields in construction projects expanding due to its good characteristics, and can be used as Retaining wal...
