A new type of pavement permeable concrete product and preparation method thereof

Abstract

The invention provides a novel road surface permeable concrete product and a preparation method of the novel road surface permeable concrete product. The permeable concrete product is prepared from the following raw materials including composite aggregate, a gel material, a composite additive and water at the weight ratio of (2.0 to 3.0) to 1 to (0.003 to 0.03) to (0.25 to 0.35); the composite aggregate is prepared from regenerated aggregate and common aggregate. The permeable concrete product prepared by the invention has water permeability with different gradients and diversified permeable rates; the 28d compressive strength of the prepared permeable concrete product is 5MPa to 15MPa and the permeable rate of the prepared permeable concrete product is 0.5mm / s to 10mm / s. According to the novel road surface permeable concrete product provided by the invention, a construction process can be simplified, and engineering construction can be finished at a single time according to actual engineering requirements; the technical effect which is the same as that of a plurality of times of construction in the prior art can be obtained; when the permeable concrete product is used for paving a side pavement on a road surface, people walking on the road surface can feel comfortable and elastic.

Description

Technical field [0001] The invention relates to the technical field of concrete, in particular to a novel pavement permeable concrete product and a preparation method thereof. Background technique [0002] With the development of concrete technology, maintaining ecological balance and achieving sustainable development are also the pursuit goals in the field of building materials. Permeable concrete products are also called porous concrete, or drainage concrete. As an environmentally friendly and ecological road material, it is water-permeable and can quickly eliminate the accumulation of water in roads and squares and reduce the burden of urban drainage; it can quickly seep rainwater into the ground, replenish groundwater, maintain soil moisture, and maintain groundwater and soil ecology Balance; it is close to the ground covered by natural vegetation in terms of heat absorption and heat storage functions, adjusts the temperature and humidity of urban space, and alleviates the u...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the permeable concrete products in the prior art that have single water permeability, difficult compaction by vibration, large product performance differences, prominent engineering quality warranty problems, cumbersome construction technology and high cost, and pedestrians feel comfortable when walking on the pavement. Poor defects, a new pavement permeable concrete product and its preparation method are proposed
