Abstract

The invention discloses a high-rupture-strength baking-free brick. The high-rupture-strength baking-free brick is prepared from the raw materials including ordinary Portland cement 42.5, gravels, medium sand, nano calcium carbonate, mineral powder, nano silicon dioxide, nano aluminum oxide, coal cash, talcum powder, ferric chloride, magnesium chloride, magnesium oxide, modified carbon fiber, asbestos fiber, plant straw, sepiolite, polystyrene emulsion, polyvinyl acetate emulsion, polyphenyl emulsion, bentyl benzene emulsion, water reducer, accelerator, thickener, polyvinyl alcohol, dispersant, diffusant, water, silane coupling agent KH-570 and modified additives. The invention also discloses a preparation method of the high-rupture-strength baking-free brick. The prepared high-rupture-strength baking-free brick is excellent in rupture strength.

Description

technical field [0001] The invention relates to the technical field of unburned bricks, in particular to an unburned brick with excellent flexural strength and a preparation method thereof. Background technique [0002] Unburned brick is a new type of wall material manufactured by using fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, etc. as the main raw materials without high-temperature calcination. The traditional unburned brick has low flexural strength, and it is easy to break during transportation and unloading, which affects the use efficiency of unburned bricks. Therefore, it is urgent to design an unburned brick with excellent flexural strength to solve the problem of existing technology. in the question. Contents of the invention [0003] In order to solve the technical problems existing in the background technology, the present invention proposes an unburned brick with excellent flexural strength and a preparation method ...
