Abstract

The invention relates to a method for producing a lightweight artificial culture stone product by adopting high-humidity sludge, and aims to provide the method capable of achieving effective digestion of the high-humidity sludge and environmental protection. The lightweight artificial culture stone product produced with the method has the characteristics of high structural strength, good weather resistance and excellent overall performance. According to the technical scheme, the method for producing the lightweight artificial culture stone product by adopting the high-humidity sludge comprises steps as follows: 1), preparation of raw materials including high-humidity sludge, washed-out sand sludge, special cement, waste foam particles or waste plastic particles, lightweight aggregate, a sludge modifier and an appropriate amount of water; 2), slurry preparation; 3), molding; 4), surface treatment; accordingly, the lightweight artificial culture stone product is obtained.

Description

technical field [0001] The invention relates to a method for producing artificial cultural stone products, in particular to a method for producing lightweight artificial cultural stone products by using high-humidity sludge. Background technique [0002] At present, the two most widely used decorative materials on the market are stone and ceramics, both of which occupy a very important market share. However, the market for ceramic decoration materials is shrinking year by year, while the market for stone is increasing year by year, and the growth rate of cultural stone reaches 50% every year. Cultural stones include natural cultural stones and artificial cultural stones. Natural stone resources are non-renewable. Therefore, with the increase in demand and the increasing shortage of resources, natural cultural stones can no longer meet the regular needs of customers. The load-bearing problem of medium and high-rise decoration (this is also an important reason why natural st...
