High-freezing-resistance archaistic black brick and preparation process thereof

Abstract

The invention discloses a high-freezing-resistance archaistic black brick and a preparation method thereof, wherein the archaistic black brick comprises clay and an air entraining agent, and the preparation method of the archaistic black brick comprises the following steps: clay pretreatment, mixing, molding, drying, roasting and red brick reduction. The raw materials comprise locally available clay, the air entraining agent, a reducing agent and the like. Sources are stabilized, the raw materials are controllable in quality, an automatic feeding and automatic stirring and mixing process can be adopted in the green brick manufacturing process, mechanical operation and automatic control are adopted in the raw material preparation process, the pore diameter system of the final green brick can be accurately controlled, the requirements for manual operation and master experience are reduced, the production efficiency is improved, and the product uniformity is improved.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a highly frost-resistant antique green brick and a preparation method thereof. Background technique [0002] With the gradual improvement of China's international status, China's unique and long-standing traditional culture has attracted attention both at home and abroad, and the ancient architecture market has therefore received more and more attention. At present, many places in China are developing ancient building protection, restoration and development projects. Taking 2015 as an example, the national ancient building market size is about 61.6 billion yuan, of which the ancient building restoration and protection market size is about 36.5 billion yuan, and the antique building scale is about 25.1 billion yuan. At present, the profit of ancient building restoration is about 8%, which is higher than that of new construction. 3% to 5% for construction is high, and the market ...

AI Technical Summary

Problems solved by technology

[0005] In North China represented by Beijing and Shanxi, there are a large number of ancient traditional buildings, and there are also a large number of new traditional buildings. However, North China is mostly in cold and severe cold areas, and has high frost resistance requirements for antique building materials. Even if antique bricks The strength, water absorption, wear resistance, and pressure and shock resistance all meet the requirements. If the antifreeze index does not meet the standard, repeated freezing and thawing in cold or severe cold areas will cause microcracks and peeling of the bricks, which will eventually lead to bricks. Decreased strength will seriously affect the quality of the wall, and the durability is poor, so frequent replacement is required, which consumes manpower and material resources and is not conducive to sustainable development
