Embodiment 1

[0028] Prepare polymer steel slag cement concrete as follows:

[0029] Heat 60 parts by weight of water to 60-90°C, then slowly add 38 parts by weight of polyphenylene sulfide resin powder and stir properly, and finally add 2 parts by weight of polyoxyethylene sorbitan laurate as an emulsifier, Shake for about 30 minutes under the action of a homogenizer to prepare a polyphenylene sulfide emulsion.

[0030] Afterwards, the concrete mix ratio design is carried out according to Table 1.

Abstract

The invention discloses a preparation method of a polymer steel slag cement concrete. The method comprises preparing polyphenylene sulfide emulsion; in a liquid-after-solid sequence, uniformly mixing,by weight part, 5-30 parts of cement, 10-40 parts of steel slag, 14-26 parts of sand, 10-30 parts of gravel, water reducer 0-0.3% as heavy as the steel slag, defoamer 0-3% as heavy as polyphenylene sulfide, 10-25 parts of the polyphenylene sulfide emulsion and 15-25 parts of water inside a mixing container to prepare the polymer steel slag cement concrete. The prepared polymer steel slag cement concrete reduces the content of alkali and chlorine ions, increases the rupture strength, the compressive strength and the bending-pressing ratio, significantly enhances strength as well as tenacity, achieves high wearing resistance and is good in durability when applied to road and bridge pavement.

Description

technical field [0001] The invention belongs to the field of road and bridge engineering, specifically a polymer steel slag cement concrete and its preparation method, which can significantly improve the durability of concrete pavement or bridge deck under the condition that other main road performance technical indicators of the material are not reduced. wear performance. Background technique [0002] In some special areas of roads, such as routes with small radius curves, bus stops, or tunnel pavements, long longitudinal slopes and other roads that are prone to wrapping and shifting, the pavement surface is subjected to repeated actions of lateral force and shear stress, and often occurs The lateral permanent deformation of the pavement surface, specifically manifested as waves, wrapping and pushing, will lead to a decrease in safety and wear resistance, resulting in traffic accidents, casualties and economic losses, especially on long steep slopes and small radius sharp t...
