preparation example Construction

[0042] A method for preparing a prefabricated building stone slab prepared from industrial solid waste, comprising the following steps:

[0043]Step 1. Preparation of formula raw materials: solid waste raw materials and mineral raw materials are dried, crushed and screened separately; the drying process uses a gas dryer, and the dried raw materials have a moisture content of 1 to 10%; the crushing process uses a jaw crusher for coarse Crushed to 30±1mm, finely crushed by hammer crusher to 5±0.5mm, pulverized by Raymond machine or vertical mill to less than 100 mesh, to obtain materials with a certain particle size distribution; the screening process is to combine solid waste raw materials and Mineral raw materials are screened into materials with a certain particle size distribution, among which solid waste raw materials are screened into 8-20 mesh as aggregate, accounting for 5-40% of the mass, ore raw materials are screened into 20-1000 mesh as filler, and the mass is Accoun...

Abstract

The invention relates to a method for preparing a stoneware batten for a fabricated building by utilizing industrial solid waste. The stoneware batten is formed by mixing solid powder and water according to the weight ratio of 1: (0.1-0.25), and comprises the following components in percentage by weight: 75%-95% of solid waste raw materials; 3%-15% of raw mineral materials; and 2%-10% of chemical raw materials. The method comprises the following steps: preparing formula raw materials; mixing and stirring; homogenizing and aging; performing vacuum pugging; performing extrusion molding; drying the green body; sintering at high temperature; and processing. The technical problems that a traditional wall material is large in volume weight, poor in waterproof effect and poor in energy-saving and heat-preserving effect are well solved.

Description

technical field [0001] The invention belongs to the technical field of application of green building materials, and in particular relates to a preparation method of using industrial solid waste to prepare stoneware slats for prefabricated buildings. Background technique [0002] The prefabricated building is a building product that combines various parts of the building into a whole. The building parts are produced and processed by the workshop, and assembled on the construction site to realize the simultaneous construction of the decoration project and the main project. Components based on standard production can be digitally and intelligently controlled on-site construction, which facilitates quality control, reduces formwork engineering and manual workload, improves construction efficiency and reduces costs. [0003] Since 2015 in my country, the development of prefabricated buildings and building industrialization has been highly valued by governments at all levels, and ...
