Embodiment 1

[0027] The invention provides a technical solution: an industrial waste permeable concrete, which consists of the following components:

[0028] Cement, siliceous sand, waste rock, fly ash, water, water reducing agent, lightweight aggregate, triethanolamine, polypropylene fiber, ordinary portland cement P.O42.5 is used as cement, and the average particle size of waste rock after crushing is The diameter is 18-22mm. The superplasticizer is a naphthalene-based high-efficiency superplasticizer, and the dosage range of the superplasticizer is 0.75% to 1.5% for powder and 1.5% to 2.5% for liquid.

Embodiment 2

[0030] The invention provides a technical solution: a method for preparing industrial waste permeable concrete: comprising the following steps:

[0031] (1) Grinding of industrial waste: Grinding the collected waste rocks. The waste rocks are ores and rocks, and the waste rocks are crushed to an average particle size of 18mm;

[0032] (2) Selection of raw materials: The sand for preparing concrete is preferably hard, free of impurities and ribbed siliceous sand grains, and the water used for preparing concrete is selected from non-polluted water. "Water Water Standard" (JGJ63-89);

[0033] (3) Preparation of fly ash ceramsite: fly ash is the main raw material, mixed with appropriate amount of calcium carbide slag, gypsum, admixture and other materials, and then prepared by metering, batching, molding, hydration and hydrothermal synthesis reaction or natural hydraulic reaction. become;

[0034] (4) Preparation of lightweight aggregate: light coarse aggregate, light sand, ceme...

Abstract

The invention discloses industrial waste pervious concrete and a preparation method thereof. The industrial waste pervious concrete is prepared from the following components: cement, siliceous sand grains, barren rock, fly ash, water, a water reducing agent, lightweight aggregate, triethanolamine and polypropylene fibers. The preparation method comprises the following steps: crushing industrial waste; selecting raw materials; preparing fly ash ceramsite; preparing a lightweight aggregate; preparing an additive; stirring and mixing. According to the pervious concrete disclosed by the invention, the fly ash and the barren rock are added into the raw materials for preparing the concrete, so that industrial wastes generated by a thermal power plant can be recycled, and the strength and the adaptability of the pervious concrete can be enhanced; the polypropylene fibers can increase the strength of the concrete and enable the concrete to become wear-resistant and corrosion-resistant, triethanolamine is used as a medium, and the polypropylene fibers can be uniformly mixed with other materials of the concrete, so that the concrete with good water permeability is better in water permeability, higher in strength and longer in service life.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to an industrial waste permeable concrete and a preparation method thereof. Background technique [0002] Permeable concrete is also called porous concrete, sand-free concrete, and permeable floor. It is a kind of porous lightweight concrete made by mixing aggregate, cement, reinforcing agent, and water. It does not contain fine aggregate. Permeable concrete is formed by covering the surface of coarse aggregate with a thin layer of cement paste and bonding each other. The honeycomb structure with evenly distributed pores has the characteristics of air permeability, water permeability and light weight. [0003] This kind of paving material can allow rainwater to flow into the ground, effectively replenish groundwater, alleviate some urban environmental problems such as the sharp drop in the groundwater level of the city, and effectively eliminate the hazards of environmen...
