Problems solved by technology

During this process, vehicles on the road are prone to skidding, causing serious safety problems; even some potholes are filled with accumulated water, and the wheels of the vehicle are easy to sink into the pit when driving to the pothole area. When there are other cars on board, it is very easy to have a traffic accident
At the same time, because it is difficult for accumulated water to penetrate the concrete surface and enter the underlying soil, it is difficult for rainwater to penetrate into the ground to form groundwater resources after falling. The groundwater resources cannot be well circulated. In the long run, the groundwater resources will only be used less and less, which is not in line with the ecological balance , poor environmental protection

Embodiment 1

[0047] Embodiment 1: A kind of environment-friendly concrete, each component and its corresponding weight ratio are shown in Table 1, and are prepared through the following steps:

[0048] Step 1, uniformly mixing cement, mineral powder, fly ash, sand, and crushed stone in a corresponding weight ratio to obtain a dry mix;

[0049] Step 2, mixing and dispersing water, water reducing agent, and metal steel balls with a diameter of 12 cm and a porosity of 40% to obtain a mixed solution with metal steel balls;

[0050] Step 3: Add the mixed liquid with metal steel balls into the dry mix, stir and mix evenly to obtain the environment-friendly concrete.

[0051] The water reducer in this embodiment is polycarboxylate water reducer, YB-C polycarboxylate high performance water reducer purchased from Hunan Yibao Building Materials Co., Ltd.

Embodiment 2-6

[0052] Example 2-6: An environmentally friendly concrete, the difference from Example 1 is that each component and its corresponding weight ratio are shown in Table 1.

[0053] Each component and its weight ratio in Table 1 embodiment 1-6.

Embodiment 7

[0056] Embodiment 7: A kind of environment-friendly concrete, the difference with embodiment 3 is that the metal steel wire ball is subjected to fluorination treatment, and the fluorination treatment includes the following steps:

[0057] (1) metal steel wire balls are put into the reactor with fluorinated liquid, the fluorinated liquid of the present embodiment is purchased from the 3MTM NovecTM7100DL fluorinated liquid of Minnesota Mining and Manufacturing Company;

[0058] (2) Feed an inert gas into the reactor, nitrogen is preferred in this embodiment, helium, xenon or argon can be used in other embodiments, the control pressure is 40Mpa; the temperature of the reactor is controlled to be 190°C, after reaching the set temperature , react for 25h;

[0059] (3) Pressure relief, wait for the reaction kettle to cool down, take out the metal steel balls, and obtain the metal steel balls after the fluorination treatment.

Abstract

The invention discloses an environment-friendly concrete and a preparation method thereof, and relates to the field of building materials. Its technical points are: the composition and weight ratio of its raw materials are as follows: cement 117‑182kg / m 3 ;Water 175‑200kg / m 3 ; Mineral powder 45‑52kg / m 3 ; Fly ash 96‑112kg / m 3 ;Sand 848‑892kg / m 3 ; Gravel 960‑977kg / m 3 ; Water reducer 2.73‑5.06kg / m 3 ;Metal steel ball 82‑87kg / m 3 . The concrete of the invention has the advantages of reducing the anti-seepage performance of the concrete floor, improving the permeability of the concrete floor, continuously replenishing underground water resources, environmental protection, and not affecting other mechanical properties of the concrete.

Description

technical field [0001] The invention relates to the field of building materials, more specifically, it relates to an environment-friendly concrete and a preparation method thereof. Background technique [0002] Ordinary concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in an appropriate proportion, and uniformly stirred, compacted and cured. . Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. [0003] A Chinese invention patent with the publication number CN106242434A discloses a high-durability concrete for road use. The raw materials of the concrete include the following components: Portland cement, coarse sand, medium coarse sand, gravel, water, coal ash powder, Blast ...
