preparation example Construction

[0033] The preparation method of described high-performance water-retaining lawn brick, comprises the following steps:

[0034] S1: mixing cement, construction waste particles, ground barley stalks and filling materials with water to obtain base material a;

[0035] S2: Microporous plastics, sulfuric acid with a mass concentration of 45-60%, and mesh-like starch are dispersed under ultrasonic waves for 3-5 hours to obtain microporous plastics deposited with mesh-like starch; After the microporous plastic of porous starch is melted at high temperature, stir while introducing carbon dioxide gas, then add the base material a obtained in step S1 and mix and stir for 5-8 minutes to obtain base material b;

[0036] S3: Add additive A, additive B, and additive C to the base material b prepared in step S2 for mixing, and the mixed and stirred material is molded by vibration and pressure, demolded, and the brick body is obtained;

[0037] S4: Paint the brick body prepared in step S2 w...

Abstract

The invention discloses a high-performance water retaining lawn tile which comprises, by weight, 15-35 parts of cement, 20-30 parts of construction waste, 10-15 parts of crushed highland barley straws, 1-2 parts of cellular plastics, 10-30 parts of sulfuric acid with the concentration of 45-60%, 0.3-0.5 part of mesh starch, 4-6 parts of pigments, 1-1.25 parts of additives A, 3-6 parts of additivesB and 3.5-7.5 parts of additives C. According to the tile, the construction waste particles, the crushed highland barley straws and the cellular plastics serves as main raw materials, the cement, themesh starch and the like serves as cementing agents to prepare the high-performance water retaining lawn tile, the tile can be used for sponge city construction, city drainage and flood prevention pressure is relieved, soil humidity is kept, survival conditions of ground vegetation and soil microorganisms of a city are improved, resource pressure is relieved to some extent, and resource utilization rate is increased.

Description

【Technical field】 [0001] The invention belongs to the technical field of building material preparation, and in particular relates to a high-performance water-retaining lawn brick. 【Background technique】 [0002] With the rapid development of urbanization and urban construction, my country is facing a series of serious ecological problems such as urban rain and flood, urban waterlogging, smog pollution, water system pollution, water resource shortage, groundwater depletion, and loss of aquatic habitats. In addition, the scale of urban housing and infrastructure construction is expanding day by day, and the amount of new construction, expansion and demolition continues to increase, resulting in a large amount of construction waste, which not only wastes a lot of resources, but also seriously affects people's living environment. According to the data, the construction waste produced by the demolition of old buildings in the whole country reaches 800 million tons every year, and...
