High strength anti-crack cement board for municipal road and preparation method thereof

Abstract

The invention relates to the field of municipal roads, and discloses a high strength anti-crack cement board for the municipal road. The high strength anti-crack cement board is prepared from the following raw materials in parts by weight: 50-80 parts of rubbles, 25-35 parts of fine sand, 20-30 parts of portland cement, 6-12 parts of aluminate cement, 5-10 parts of superfine ore powder, 5-10 partsof glazed micro bead, 1-2 parts of methylsilicone oil, 4-8 parts of phenolic resin, 2-5 parts of asbestos fiber, 0.2-0.5 part of anhydrous sodium sulfate, 0.2-0.5 part of sodium hydrogen sulfate, 0.3-0.6 part of polycarboxylate water reducer, 2-4 parts of ethylene glycol distearate, 10-15 parts of an additive and 20-30 parts of water. The invention further discloses a preparation method of the high strength anti-crack cement board for the municipal road. The prepared cement board has the high strength, can bear the strong external force effect, is not prone to being pressed to be broken, andhas the longer service life.

Description

technical field [0001] The invention relates to the field of municipal roads, in particular to a high-strength anti-cracking cement board for municipal roads and a preparation method thereof. Background technique [0002] Cement board is a kind of building slab produced by processing cement as the main raw material. It is a building product that can be cut, drilled and carved freely between gypsum board and stone. It is superior to gypsum board and wood board. Fireproof, waterproof, anti-corrosion, insect-proof, sound-proof, and the price is far lower than stone, so it has become a widely used building material in the construction industry. There are prefabricated and cast-in-place cement boards. [0003] Cement boards are often used when laying municipal roads. The roads paved with cement boards are generally for pedestrians to walk on. Therefore, the strength of the cement boards used is relatively low. In actual use, vehicles often drive on the roads. Vehicle rolling is ...

AI Technical Summary

Problems solved by technology

[0003] Cement boards are often used when laying municipal roads. The roads paved with cement boards are generally for pedestrians to walk on. Therefore, the strength of the cement boards used is relatively low. In actual use, vehicles often drive on the roads. The rolling of the vehicle is easy to break, resulting in a lower service life of the cement board, more troublesome maintenance, and a waste of financial expenditure
