[0036] The preparation method of described novel concrete environment-friendly brick comprises the following steps:

[0037] S1: Preparation of hollow bricks

[0038] Mix cement, shale ore, fly ash, tailings sand, and slag, and stir evenly at a speed of 200-400r / min to make hollow bricks;

[0039] S2: Preparation of cement foam material

[0040] S21: Stir cement, glyoxal and water evenly at a speed of 100-300r / min to prepare a slurry;

[0041] S22: Calcium carbonate, calcium silicate, limestone, magnesium borate, wheat straw powder, AR glass fiber, carboxymethyl cellulose, water reducer, foaming agent, foam regulator, catalyst, crosslinking agent and foam stabilizer The agent is stirred for 2-3 hours at a speed of 60-100r / min to obtain a foam liquid;

[0042] S23: Add the foam liquid prepared in step S22 to the slurry prepared in step S21, and stir evenly at a rotating speed of 150-200r / min to obtain a cement foam material;

[0043] S3: Preparation of insulation bricks

Description

【Technical field】 [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a novel concrete environmental protection brick. 【Background technique】 [0002] With the popularization of building energy saving and the continuous improvement of people's demand for the comfort of living environment, thermal insulation materials have been paid more and more attention by people. Existing thermal insulation composite bricks or blocks mainly include multiple forms such as inlaying thermal insulation materials, setting thermal insulation interlayers, thermal insulation holes, and trenches. As one of the thermal insulation materials for houses, non-fired foamed bricks at room temperature are more and more popular because of their thermal insulation, sound insulation, fire prevention, and strength superior to traditional thermal insulation materials. However, the foamed bricks in the existing market have disadvantages such as poo...
