Problems solved by technology

However, the emery sand wear-resistant floor still uses cement base as the cementitious material. Although the wear resistance and strength have been improved, there are still some defects of traditional cement materials, such as easy to crack, cracks appear on the surface, and cracks caused by deformation , The incidence of cracks is relatively high

preparation example Construction

[0081] A preparation method of a highly crack-resistant and wear-resistant floor material, comprising the following preparation steps:

[0082] Step 1: Add Portland cement, aggregate, admixture, water reducer, redispersible latex powder, and early strength agent into the reactor and stir for 10 to 65 minutes to form a mixed solution;

[0083] Step 2: Add fibers to the mixture in Step 1, and stir for 10-60 minutes to obtain flooring materials.

[0084] In this embodiment, the reactor is a dry powder mortar mixer.

[0085] After the fiber is mixed, it can act as a high elastic modulus material compared with the plastic slurry, and the surface adsorption viscosity and mechanical tooth force of the cement slurry and the fiber material will significantly improve the cracking resistance of the concrete material, and at the same time enhance its plastic tensile strength. Strength, and because the dehydration shrinkage stress is significantly smaller than the plastic tensile strength o...

Embodiment 1

[0087] Embodiment one: by preparing 1000 kilograms of emery sand wear-resistant floors, add 377.5 kilograms of Portland cement that the strength grade is PⅡ42.5R by the following weight, 18 kilograms of silica fume, and 600 kilograms of quartz sand with a mesh number of 20, 0.2 kg of polycarboxylic acid high-efficiency water reducer, 2 kg of ethylene and vinyl acetate copolymer latex powder, 2 kg of calcium formate and stir in the dry powder mortar mixer for 30 minutes, then add 0.3 kg of polypropylene fiber after the stirring is completed, and stir for 40 minutes to obtain Product of the present invention.

Embodiment 2

[0088] Embodiment two: by preparing 1000 kilograms of emery sand wear-resistant floor meter, adding strength grade is 375 kilograms of portland cement of PⅡ42.5R by the following weight, 20 kilograms of silica fumes, 600 kilograms of quartz sands of 30 meshes, 0.2 kg of naphthalenesulfonic acid formaldehyde condensate, 2 kg of latex powder of vinyl acetate and vinyl tertiary carbonate copolymer, 2 kg of calcium formate and stir in the dry powder mortar mixer for 30 minutes, add 0.8 kg of polypropylene fiber after the stirring is completed, and stir for 40 Minutes, obtain product of the present invention.

Abstract

The invention relates to the technical field of building materials. The invention relates to a terrace material, in particular to a high-crack-resistance wear-resistant terrace material and a preparation method thereof. The high-strength concrete comprises the following components in parts by weight: 250-550 parts of Portland cement, 300-800 parts of an aggregate, 0.1-50 parts of an admixture, 0.1-5 parts of a water reducing agent, 0.1-8 parts of redispersible latex powder, 0.05-5 parts of fibers and 0.1-5 parts of an early strength agent. The terrace material has the advantages of being resistant to cracking and cracking, high in abrasion resistance, high in pressure resistance, hard in surface, economical, durable, good in impact resistance, long in service life and the like; by adding the fiber material, the internal structure of the terrace material can be obviously improved, the micro-crack condition is avoided, and the extension of cracks is reduced, so that the toughness, the impermeability and the wear resistance of the terrace material are enhanced.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a highly crack-resistant and wear-resistant floor material and a preparation method thereof. Background technique [0002] Although the concrete material has high strength, there are still some defects in the use of ordinary concrete. For example, the concrete floor is easy to generate dust, easy to wear, and its performance decreases sharply over time. Therefore, in industrial plants, parking lots, supermarkets, warehouses and other places that require frequent impact loads and require cleanliness, a layer of corundum high wear-resistant layer is generally poured on the concrete surface as a floor material during construction. [0003] The emery wear-resistant floor is in the initial setting stage of the base concrete, and the wear-resistant material is evenly spread on the concrete surface, and it is constructed by professional machinery, so that it forms a whole wit...
