Problems solved by technology

As the content of fine aggregate decreases, the particle size of coarse aggregate is larger and the specific surface area is smaller, so that the contact points between aggregate particles are less, and the bonding strength is lower, resulting in lower compressive strength of concrete

Abstract

The invention relates to colored water-permeable concrete and a preparation method thereof, and belongs to the technical field of concrete production, the colored water-permeable concrete comprises the following components in parts by weight: 260-350 parts of cement, 80-90 parts of water, 1200-1300 parts of coarse aggregate, 5-7 parts of hybrid fiber, 3-6 parts of whisker filler, 2-4 parts of silicone acrylic emulsion, 25-35 parts of pigment and 3-5 parts of water reducing agent; wherein the hybrid fibers comprise steel fibers and nano calcium carbonate modified plant fibers; the preparation method comprises the following steps: S1, uniformly mixing and stirring the hybrid fibers and water; and S2, sequentially adding the excess materials into the mixture obtained in the step S1, and uniformly stirring to obtain the colored water-permeable concrete. The colored pervious concrete has the effect of improving the compressive strength of the colored pervious concrete.

Description

technical field [0001] The application relates to the field of concrete production, in particular to a colored permeable concrete and a preparation method thereof. Background technique [0002] Colored permeable concrete, also known as porous concrete, can also be called drainage concrete. It is made of a layer of thin slurry wrapped on the surface of coarse aggregate and bonded to each other to form a honeycomb shape, which allows rainwater to flow into the ground, effectively replenishes groundwater, maintains soil moisture, and maintains groundwater. And the ecological balance of the soil; and can effectively eliminate the oil compounds on the ground and other environmental pollution hazards; in addition, the colored permeable concrete is colorful and integrated with the landscape, making the urban environment construction more harmonious, which is to protect nature, maintain ecological balance, Excellent permeable floor materials that can alleviate the city's "heat islan...
