Problems solved by technology

[0004] One is that the late strength shrinkage phenomenon of cement is more serious; mainly hexagonal CAH 10 and C 2 AH 8 (needle, flaky crystal) to cubic C 3 AH 6 The transformation is mainly caused by the fast hydration time of aluminate cement, and some substances in the cement slurry caused by the initial setting period have not been fully hydrated; in addition, the magnitude of the later strength shrinkage of the cement is also closely related to the temperature;
[0005] The second is the phenomenon of fracture and frost in the later use of inorganic artificial stone
[0006] Third, during the manufacturing process of cement-based artificial stone, after thickness setting and polishing, the unpolished surface is prone to release of alkali metal ions after contact with water in the later stage, such as Ca(OH) 2 etc., causing the edge part to fall off, affecting the performance and quality of the product
But it also has disadvantages. Due to the large particles of pumice, it is not suitable to mix more
In addition, the pumice itself cannot play a load-bearing role. When the cement shrinks later, the large-volume pores inside the pumice will generate greater stress, causing the artificial stone to crack. Compared with natural stone and other The compressive strength of cement-based artificial stone will decrease

Description

technical field [0001] The invention belongs to the technical field of artificial stone preparation, and relates to an inorganic artificial stone containing high-performance ceramsite and superabsorbent resin and a preparation method thereof. Background technique [0002] my country is the world's largest stone production, sales and export country, with an annual output value of more than 100 billion yuan. In the early stage of stone production, blocks were mainly mined by mining and then processed into natural stone. On the one hand, due to the low mining efficiency, the highest yield rate was only 30%, which made precious natural resources waste. What's more, All kinds of wastes are buried in gullies, which is easy to cause natural disasters such as landslides. On the other hand, with the over-exploitation of natural mineral resources, the price of natural stone continues to rise, which also hinders the development of stone in the application market. [0003] With the ris...
