Embodiment 1

[0035] A kind of permeable concrete containing river silt powder is made according to the following steps:

[0036] (1) Take the river silt and first filter it to remove impurities, then dry it in the sun, and finally carbonize it at 300° C. for 30 minutes to obtain the river silt powder;

[0037] (2) weigh out the required river channel silt powder, cement, sand, stone, granular carbon, sodium lignin sulfonate and polycarboxylate water reducing agent for making concrete by weight distribution ratio;

[0038] Its weight distribution ratio is:

[0039]

[0040] (3) Wet the mixer, tools and other contact equipment with water, then pour cement, river sludge powder, granular carbon, sodium lignosulfonate and polycarboxylate water reducer into the mixer and stir evenly, then add an appropriate amount of water, After stirring for 3-5 minutes, add stones to the blender and continue stirring until uniform.

Abstract

The invention discloses water-permeable concrete which contains river sludge powder. The water-permeable concrete comprises the following raw materials in parts by weight: 15-20 parts of the river sludge powder, 20-28 parts of cement, 15-22 parts of water, 115-126 parts of gravels, 3-10 parts of gelatinizing agents, 1-6 parts of additives and 5-10 parts of granular carbon, wherein the river sludge powder is obtained by filtering, drying and carbonizing river sludge. The invention also discloses a water-permeable concrete brick made by adopting the water-permeable concrete containing the river sludge powder of the claim 1. The recyclable concrete material provided by the invention is prepared by matching a material formed by drying the river sludge at high temperature with the granular carbon and has the advantages of recyclability, water permeability, high strength, low cost, simple preparation process, very good development prospect and the like.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to permeable concrete and concrete bricks containing river silt powder. Background technique [0002] In the existing concrete, there are generally disadvantages such as low concrete tensile strength, large amount of cement input, non-renewable, and impermeable. This also adds a lot of trouble to the construction field. In today's society that advocates energy conservation and environmental protection, efficient use of resources and environmental protection of materials have increasingly become the theme of the times. The construction industry has always been closely related to people's lives, and the utilization rate of resources in the construction field also directly affects people's quality of life. [0003] At present, under the trend of rapid development of the construction industry, the investment in concrete is also increasing in the field of construction, and most of the...
