Problems solved by technology

[0002] At present, with the increasing scale of urban residential renewal and municipal relocation, many concrete buildings and structures need to be demolished for redesign and construction, and these demolished waste concrete are often stacked in the wild without rational use, affecting the ecology environment, not conducive to ecological balance
In addition, due to the characteristics of sidewalk bricks, it is required to be able to seep water quickly and have a certain strength. However, the environmental protection concrete sidewalk bricks of the prior art all use gravel or sand or cinder as aggregates, while quarrying and sand mining are damaged. The ecological environment is damaged, and the strength of sidewalk bricks prepared from cinders is not enough

Abstract

The invention discloses an environment-friendly concrete sidewalk brick. The brick is prepared from water, cement, waste concrete aggregate or tailings, and a concrete antalkali, wherein the specific mix proportion is that water to cement to waste concrete aggregate or tailings is (0.4 to 0.46) to 1 to 4; the using amount of the concrete antalkali is 22 to 25 percent of that of the cement; the concrete antalkali is prepared from 55 to 65 percent by weight of kieselguhr, 20 to 40 percent by weight of zeolite, and 5 to 15 percent of echinacea extract, the cement is ordinary portland cement with a mark number of 52.5R. Compared with the prior art, the brick provided by the invention has the characteristics that the overall performance is good and environmental friendliness is realized and protective effect is realized.

Description

Technical field: [0001] The invention relates to an environment-friendly concrete sidewalk brick. Background technique: [0002] At present, with the increasing scale of urban residential renewal and municipal relocation, many concrete buildings and structures need to be demolished for redesign and construction, and these demolished waste concrete are often stacked in the wild without rational use, affecting the ecology The environment is not conducive to ecological balance. In addition, due to the characteristics of sidewalk bricks, it is required to be able to seep water quickly and have a certain strength. However, the environmental protection concrete sidewalk bricks of the prior art all use crushed stones or sandstone or cinder as aggregates, while quarrying and sand mining are destroyed. The ecological environment is damaged, and the strength of sidewalk bricks prepared from cinders is not enough. Invention content: [0003] The object of the present invention is t...
