preparation example Construction

[0028] A permeable cement concrete mixed with rubber disclosed in the embodiment of the present invention comprises the following components in parts by weight: 1100-1400 parts of aggregate; 160-480 parts of waste rubber particles; 360-500 parts of cement; 90 parts of water -125 parts; 10-20 parts of latex; 15-30 parts of silica fume; 5-15 parts of basalt fiber; 3-4 parts of water reducing agent. Its preparation method is as figure 1 As shown, it mainly includes the following steps:

[0029] (1) Put the rubber particles in a metal container, add a silane coupling agent with a mass fraction of 1.5% of the rubber particles, add water to dissolve fully, stir fully to ensure that the rubber particles are in full contact with the silane coupling agent solution, and place in a dry place Wait until the surface of the rubber particles is completely dry in the environment.

[0030] (2) Prepare the above-mentioned required materials, mix the aggregate and rubber particles evenly, pour...

Embodiment 1

[0067] Example 1: permeable concrete mixed with rubber, including aggregate, waste rubber particles, cement, water, latex, silica fume, basalt fiber and high-efficiency water reducer. Each material is calculated in parts by weight, and the content of each component is shown in Table 4. The waste rubber particles are treated with KH560 silane coupling agent with a mass fraction of 1%-1.5%.

Embodiment 2

[0068] Embodiment 2: permeable concrete mixed with rubber, the difference from embodiment 1 is that the content of aggregate is reduced.

Abstract

The invention discloses rubber-doped water-permeable cement concrete and a preparation method thereof. The concrete comprises the following components in parts by weight: 160-480 parts of waste rubbergranules, 360-500 parts of cement, 90-125 parts of water, 10-20 parts of latex, 15-30 parts of silicon ash, 5-15 parts of a basalt fiber and 3-4 parts of a water reduction agent, wherein basalt is adopted as aggregate and has a particle size of 5-10mm; the waste rubber granules have a particle size of 1-3mm; a silane coupling agent is adopted for modification treatment. The rubber-doped water-permeable cement concrete disclosed by the invention has road strength meeting use requirements of pedestrians; in addition, a waste rubber material can be recycled, and a pavement has certain flexibility; because of a porous structure, the material has good water permeability and is an environmental-friendly material.

Description

technical field [0001] The invention belongs to the field of cement concrete pavement materials, and relates to a porous semi-flexible rubber permeable concrete material mainly used on sidewalks and a preparation method thereof, which has the characteristics of both rubber concrete and permeable concrete. Background technique [0002] According to relevant data, in recent years, an average of 1.5 billion tires have been discarded in the world every year. As a major car-using country, the number of waste tires produced in China has exceeded 300 million each year, and it is increasing at a rate of 10% per year. The disposal of waste rubber has always been a big problem. At present, my country mainly disposes of waste by burning, which obviously causes a lot of air pollution, and the efficiency of chemical decomposition and other methods is not high enough. Therefore, rubber concrete has been used since the late 1980s. The attention of scholars at home and abroad, by mixing rubbe...
