Abstract

The invention discloses a concrete material for pavement slabs and a preparation method thereof and relates to the technical field of pavement slabs. The concrete material is made from composite cement, clay-grade mica, high-silicon iron tailings, carbide slag, porous zirconia ceramic, rectorite, quartz sandstone, chrysotile fiber, sodium polyacrylate, barium chloride, a swelling agent, an early strength agent, a water-holding agent, and a dispersant. The preparation method herein includes: performing ball milling on raw materials, and stirring and mixing. The concrete material herein is convenient and simple to prepare, is green, has good comprehensive properties, can resist adhesion of adhesive matters, such as chewing gum, is convenient to clean, and provides improved cleanliness and water perviousness for pavement slabs, as well as road environment and city appearance.

Description

technical field [0001] The invention relates to the technical field of road slabs, in particular to a concrete material for a road slab and a preparation method thereof. Background technique [0002] Concrete pavement refers to the pavement with cement concrete as the main material, referred to as concrete pavement. Also known as rigid pavement, commonly known as white pavement, is a high-grade pavement. Cement concrete pavements include plain concrete, reinforced concrete, continuously reinforced concrete, prestressed concrete and other pavements. It should have sufficient strength, durability, surface anti-skid, wear resistance, flatness and other properties. However, in the prior art, the performance of the concrete pavement is poor in the above-mentioned comprehensive performance, and there are quality problems such as high cost, low compressive strength, short service life, etc., which seriously affect the hidden danger of road safety, and the water permeability of th...
