Autoclaved aerated concrete masonry block and production method thereof

Abstract

The invention relates to an autoclaved aerated concrete masonry block production method, in particular to an autoclaved aerated concrete masonry block and a production method thereof. The autoclaved aerated concrete masonry block production method includes the steps of (1) pouring slurry into a die box; (2) fixing at least one core rod on the die box via a positioning device and enabling part of each core rod to be immersed in the slurry; (3) placing the die box processed in the step (2) in a drying room, standing still and foaming till the slurry is formed into a blank body; (4) separating the core rods from the die box; and (5) overturning, cutting and steaming the formed blank body obtained in the step (3). The invention aims at providing an autoclaved aerated concrete masonry block die and the autoclaved aerated concrete masonry block production method, and the autoclaved aerated concrete masonry block production method has the advantages that heating is even, the masonry block is lightened, and consumed raw materials are reduced.

Description

technical field [0001] The invention relates to a production process of an autoclaved aerated concrete block, in particular to a porous autoclaved aerated concrete block and a production method thereof. Background technique [0002] At present, large-scale urban infrastructure construction, housing construction, and project construction to improve people's livelihood are being carried out in many areas of our country. However, the scarcity of land resources makes the buildings built higher and higher, and the load-bearing capacity of the land has almost reached the limit. In many places, safety accidents such as foundation sinking and building tilting have occurred. How to develop lighter and safer building materials is a key issue. major issues for the future. [0003] With the development of science and technology, various lightweight building materials have also appeared one after another. At present, autoclaved aerated concrete blocks are widely used in China. Its adva...

AI Technical Summary

Problems solved by technology

At present, autoclaved aerated concrete blocks are widely used in China. Its advantages are simple process, low production cost, light weight (average density is 600~700KG / m3), and low construction cost. The process consumes a lot of heat energy. Due to the large size of the brick body, it is easy to appear the phenomenon that the outside is cooked and the inside is not steamed through, and the product is easy to deform, which brings a great hidden danger to the building safety; during the storage and transportation of the brick body , most manufacturers use manual loading and unloading, because the overall weight of the brick body is heavy, and the labor force is too large, which increases the cost of product storage and transportation; in addition, the raw materials for the production of autoclaved aerated concrete blocks are mainly fly ash, cement, Quicklime, river sand and foaming additives, etc., but the prices of these raw materials are increasing year by year, especially the most used fly ash. With the wide application of fly ash, it has changed from waste to treasure at the beginning. The price of the region has even exceeded 100. How to minimize the use of raw materials and reduce the production cost without affecting the product quality will be the subject of future research.
