Colorful water permeable concrete pavement and construction technique

Abstract

The invention relates to a chromatic pervious concrete pavement material and a construction process thereof, which is characterized in that the formulation of a special concrete binding agent comprises 85 to 92 percents of cement (weight), 5 to 10 percents of silicon ash, and rubber powder, early strength admixture, water reducing agent and paint. The ash collection ratio is 4.0 to 6.0; the water cement ratio is 0.30 to 0.40; dry power shaped binding agent, aggregate and water are added in a concrete agitator according to the blending ratio so as to be churned into a mixture with uniform and proper dryness and humidity, which is then is used for paving and construction after being flattened; a low frequency flat oscillator is used for vibrating, compacting and leveling on the surface; the water is poured for maintenance; oily crylic acid resin is taken as mat coat agent to ensure that the color of the pavement is fresh. The chromatic pervious concrete pavement material and the construction process thereof have the advantages that steel-making industrial waste residue is adopted as the aggregate to change waste into valuables; the problem of low strength of the non-sand water permeability concrete material with a plurality of holes is solved by lower cost; compared with the high molecule permeable material, the cost is low, the strength is high, and the ageing resistance is good; compared with the sintering ceramics permeable material, the cost is low, the energy consumption is reduced, and the permeability effect is strong.

Description

technical field [0001] The invention belongs to the technical field of pavement materials and construction, and in particular relates to a colored high-strength permeable concrete pavement material and a paving construction process thereof. Background technique [0002] With the development of social economy and the continuous advancement of urban construction, the surface of modern cities is gradually covered by reinforced concrete buildings and impermeable roads. Ordinary concrete pavement lacks breathability, absorbs heat and infiltrates rainwater poorly, which brings a series of environmental problems. Ordinary concrete uses cement, ordinary stones, sand, and water as raw materials. They are fully mixed and stirred to form a uniform slurry. After pouring, the cement and water undergo a chemical reaction, and the stones and sand are closely packed, and the cementitious material is filled and hardened on the piled stones. The dense pores between the sand make the concrete...

Problems solved by technology

However, the sintering process requires energy consumption and high cost

And the water permeability effect is general, because the pores are small, it is easy to be blocked in the process of use
