Problems solved by technology

[0005] However, in the existing technology, acidic soil and the addition of weakly acidic substances are used to neutralize the dissolved alkali to reduce the alkalinity value in the pores. Although the alkalinity of the pores of porous concrete can be reduced to a certain extent, its dosage has no effect on the strength. The reduction effect is obvious, FeSO 4 The amount of acidic substances should not be too much
The pH value of the pore water environment of ecological concrete treated with wax sealing is only reduced by 0.5-1, and the overall process is complicated and the cost is high, and the industrialization prospect is not optimistic

Abstract

The invention provides steel slag vegetation concrete, which is prepared from the following components in parts by weight: 75 to 83 parts of steel slag aggregate, 15 to 24.5 parts of composite steel slag powder and 0.5 to 2 parts of strengthening agent. A preparation method comprises the steps of uniformly stirring and mixing the steel slag aggregate and the composite steel slag powder as well as the strengthening agent proportionally, and adding water to produce the steel slag vegetation concrete. The steel slag vegetation concrete prepared by utilizing steel slag is high in strength, large in porosity and an acid-base environment can meet the requirement of growth of plants.

Description

technical field [0001] The invention belongs to the field of ecological concrete, and mainly relates to a steel slag planting concrete and a preparation method thereof. Background technique [0002] Under the concept of actively advocating green life, energy saving and environmental protection, our country is not only focusing on the structural performance of concrete in the past, but also gradually developing towards the direction of functional concrete such as environmental friendliness and resource conservation. Plant-growing concrete, which originated in Japan, not only has the function of concrete, but also has the function of environmental regulation, and realizes the needs of ecologicalization. Vegetative concrete is used on both sides of the city's roads, highway slope protection and central isolation belt, waterside slope protection, roof parking lot and other parts, which can increase the water permeability and air permeability of the surface of the concrete materi...
