Embodiment 1

[0031] According to each cubic meter of concrete, the following weight proportions are included:

[0032] Cement: 250kg~300kg;

[0033] Water: 100~120kg;

[0034] Coarse aggregate: 1350~1420kg;

[0035] Fine aggregate: 200~250kg;

[0036] ZS series concrete admixture: 5L;

[0037] Pigment: 12.5~15kg

[0038] Wherein, the amount of the components varies according to the field test results; generally, the compressive strength is between 10-35MPa (28-day strength), the porosity is controlled at 10-30%, and the water permeability coefficient is controlled at 0.5-5cm / s. The pH value of ecological concrete is controlled at around 10.

[0039] Common Portland cement is generally used as cement. According to the design strength of ecological concrete, different grades of cement are generally used. If the design strength is C10-C20, No. 325 cement can be used; if the design strength is C20-C30, No. 425 cement can be used; if the design strength is above C30, No. 525 cement shoul...

Abstract

The invention relates to concrete, in particular to cast-in-situ colored permeable ecological concrete and a road surface construction process thereof. Each cubic meter of concrete is prepared from the following raw materials by weight: 200 to 350 kilograms of cement, 80 to 150 kilograms of water, 1,200 to 1,550 kilograms of coarse aggregates, 180 to 280 kilograms of fine aggregates, 4.5 to 5.5 liters of ZS series concrete admixture and 10 to 18 kilograms of pigment. The ecological concrete can be mixed by utilizing a mixing plant; and after being conveyed to a construction site by a commercial concrete mixer and added with the admixture, the ecological concrete can be subjected to the pouring constructing of road surfaces directly without vibrating and are only needed to be plastered by a metal trowel, so the construction efficiency is improved greatly. The ecological concrete is used for road surface engineering, uses a small amount of the cement, has high strength and water permeability, and can be widely applied to light traffic road surfaces such as side pavements, parks, neighborhoods and the like.

Description

technical field [0001] The invention relates to concrete, in particular to a cast-in-situ colored permeable ecological concrete and a pavement construction process thereof. Background technique [0002] As a construction material, concrete is widely used in infrastructure and various buildings due to its many advantages such as ease of material supply, freedom of forming, durability and fire resistance, and has made great contributions to social development. big contribution. However, the extensive use of concrete also destroys the natural environment such as trees and water, and hinders the habitat of animals and plants. Coupled with the neglect of river and lake resource management and ecological environment protection, it is easy to cause soil erosion, landslides, mud-rock flows, soil desertification and salinity. A series of natural disasters such as alkalization. As a developing country, China is facing this severe problem. Therefore, in the 21st century, human being...
