Embodiment 1

[0047] A construction method for producing concrete and concrete pavement, comprising the following steps:

[0048] Step 1. Premixing: put 160 parts of Portland cement, 400 parts of pumice, 80 parts of fly ash, and 200 parts of yellow sand into the mixing equipment and stir until uniform. The speed of the mixing equipment is 26r / min. The mixing time is 7 minutes to form pre-mixed concrete;

[0049] Step 2: Injection molding ABS by injection molding machine such as figure 1 As shown in the mesh plastic 1, the mesh plastic 1 includes several interconnected branches 2, and the diameter of each branch 2 is 5 mm;

[0050] Step 3. Remixing: Put the mesh plastic 1 into the pre-mixed concrete in the mixing equipment. The rotation speed of the mixing equipment is 2r / min, and the mixing time of the mixing equipment is 4 minutes. Stir until it is uniform to form the finished concrete. The volume of reticulated plastic 1 is 0.1m³ per 1m³ of finished concrete on average.

Abstract

The invention discloses a concrete, a production method and a construction method. The concrete is prepared from, by weight, 160-190 parts of Portland cement, 150-400 parts of lightweight aggregate, 60-80 parts of fly ash, 200-300 parts of yellow ground, and 30-50 parts of mesh plastics. The melting point of a mesh-shaped plastic is lower than 260 degrees. The mesh-shaped plastic has good structure intensity; after the concrete is dried, a mesh-shaped structure is generated in the concrete, thus the concrete structure intensity, compressive strength and splitting strength of concrete are improved.

Description

technical field [0001] The invention relates to a concrete and a production method and a construction method. Background technique [0002] Concrete is a general term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering. [0003] At present, in urban construction, most of the road surfaces are paved with concrete. In the prior art, the invention patent with the notification number "CN103951348A" discloses a kind of concrete, which obtains concrete with high structural strength by mixing ordinary Portland cement, iron powder and fly ash, but this kind The structural strength and splitting strength of concrete are still u...
