Problems solved by technology

The lightweight aggregates in the existing lightweight prefabricated partition wall components lightweight aggregate foam concrete are all fired ceramsite, fired ceramsite is made of natural clay, shale and other raw materials into balls, then roasted at high temperature and expanded. Man-made lightweight aggregates have low strength. Because these raw materials consume natural resources and damage the ecological environment, and high-temperature roasting consumes high energy and pollutes, they do not conform to the principle of sustainable development

preparation example Construction

[0040] The present invention also provides a preparation method of the solid waste non-fired ceramsite described in the above technical scheme, which includes the following steps:

[0041] The first mixing of steel slag powder, slag powder, cement and density regulator to obtain a solid mixture;

[0042] Perform a second mixing of the activator and part of the water to obtain the activator solution; the amount of the part of the water is 2 / 9 to 3 / 9 of the mass of the total water;

[0043] Performing a third mixing of the solid mixture and the activator solution to obtain the material to be granulated;

[0044] The remaining water is sprayed into the material to be granulated for granulation to obtain solid waste non-burning ceramsite.

[0045] In the present invention, steel slag powder, slag powder, cement and density regulator are first mixed to obtain a solid mixture. The present invention has no special requirements for the first mixing, as long as the mixing is uniform. In the em...

Abstract

The invention belongs to the technical field of building materials, and particularly relates to a solid waste unfired ceramsite, a preparation method thereof, foam concrete and a light partition board. The solid waste unfired ceramsite provided by the invention is prepared from the following preparation raw materials in percentage by mass: 50 to 55 percent of steel slag powder, 10 to 15 percent ofore slag powder, 5 to 10 percent of cement, 1 to 5 percent of an excitant, 3 to 5 percent of a density regulator and 20 to 30 percent of water. The stacking density of the solid waste unfired ceramsite provided by the invention is 600-700kg/m<3>, the cylinder compressive strength is 8-12MPa, and the water absorption rate is 6-8%. The baking-free ceramsite foam concrete prepared from the solid waste baking-free ceramsite has relatively low density and a heat conductivity coefficient, and also has excellent compression resistance and stability.

Description

Technical field [0001] The invention belongs to the technical field of building materials, and specifically relates to a solid waste non-fired ceramsite and a preparation method thereof, a foam concrete and a lightweight partition wall board. Background technique [0002] Since the 1980s, lightweight aggregate concrete has been rapidly developed in civil residential buildings. Since the 1990s, the production and application of lightweight aggregate concrete has been increasing, especially its application in frame buildings. It has successfully replaced sintering Clay bricks have become the most promising new wall material. [0003] In recent years, the requirements for building energy efficiency have become higher and higher. Wall material innovation is the general trend. New wall materials are the main development direction of my country’s long-term wall material innovation. Among the new wall materials, lightweight aggregate foam concrete Excellent construction performance, and i...
