New frost resistant vegetation concrete using gangue as crude aggregate

Abstract

The invention discloses a new frost resistant vegetation concrete using gangue as crude aggregate to replace part of stones, and the new frost resistant vegetation concrete can be used in northern region road, river and reservoir slope protection and mountain repair and other projects, and belongs to the field of building engineering materials. Under the condition of no affect on the strength and porosity, optimum added quantity of the gangue for replacing the stones can be determined, corresponding measures are taken to enable the northern region requirements on concrete frost resistance to be met, optimum ratio and optimum admixture mixing amount and the like can be determined. The new frost resistant vegetation concrete can effectively solve the disadvantages of traditional slope protection and the difficult problems of slope protection of north cold regions in winter in China, can achieve the purpose of plant growth and greening, at the same time, can make full use of waste gangue to solve the problem of occupation of land resources and pollution of the environment due to large-amount accumulation of the waste gangue, can reduce the use of the stones, reduce the cost and protect the resources, and has more broad application prospects in the background of vigorously promoting energy conservation and environmental protection in China.

Description

(1) Technical field [0001] The invention relates to concrete used for road, river, reservoir slope protection and mountain restoration, and belongs to the field of construction engineering materials. (2) Background technology [0002] Today's roads, rivers, reservoir slopes and damaged mountain restoration are increasingly emphasizing greenness and ecology. Traditional slope protection materials have been difficult to meet the requirements. The main problems are as follows: ① Although concrete slope protection and stone slope protection materials have high strength and durability However, its surface texture is brittle and hard, the surface is rough, and the color is dark at the same time, and the visual effect lacks vitality. The space constructed by it gives people a rough, hard, cold, and dark feeling, and green vegetation cannot grow on it; ②The perforated slope protection materials are relatively simple to make and have a certain greening effect, but the greening area i...

Problems solved by technology

[0002] Today's roads, rivers, reservoir slopes, and damaged mountain restoration are increasingly emphasizing green and ecology. Traditional slope protection materials have been difficult to meet the requirements. The main problems are as follows: ① Although concrete slope protection and stone slope protection materials have high strength and durability However, its surface texture is brittle and hard, the surface is rough, and the color is dark at the same time, and the visual effect lacks vitality. The space constructed by it gives people a rough, hard, cold and dark feeling, and green vegetation cannot grow on it; ②The hole-type slope protection material is relatively simple to make and has a certain greening effect, but the greening area is small, and the diameter of the hole is large, and the soil in the hole has disadvantages such as poor washing resistance and easy loss.

③The greening effect of simple vegetation slope protection technology is good, and the vegetation substrate has a certain strength, but it is easy to lose, collapse and lose its protection ability after long-term immersion and erosion in rainwater

④ Vegetation concrete technology has been developed in my country, but its anti-freeze performance is poor, and it is basically not suitable for cold regions

[0004] The disadvantage of current engineering slope protection technology is the lack of ecological effects, but it only plays a role in supporting and reinforcing the slope, while the ecological effect of vegetation slope protection is remarkable, but the anti-scouring and anti-immersion capabilities are poor, so the current academic and engineering circles When considering vegetation slope protection, it is not only to unilaterally achieve slope greening or slope reinforcement, but to organically combine engineering protection and vegetation protection
