The cement-based wear-resistant floor materials are dry-blended materials composed of Portland cement, ordinary portland cement, and wear-resistant aggregates, which are added with appropriate additives.

Classification of cement-based wear-resistant floor materials

The cement-based wear-resistant floor materials can be classified according to their aggregates: Type I cement-based wear-resistant floor materials (non-metallic oxide aggregates); and Type II cement-based wear-resistant floor materials (metal oxide aggregates or Metal aggregates) two types.

(The raw materials are divided into two types: alloy aggregate and mineral aggregate. They are used in industrial plants, workshops, warehouses, docks, parking lots, material centers, underground garages, squares, etc.).

Ground engineering refers to the special ground that is needed for civil engineering to adapt to various uses. Floors are the simplest to use according to the type of application. This classification starts with “requirements” and mainly includes: requirements for high impact, high wear resistance required for roadways, parking lots, logistics warehouses, etc.; such as machining workshops Requirements for oil penetration on the ground; Requirements for chemical production of chemical resistant media; Computer control room, flour production dust, textile fiber dust, fuel oil, flammable and explosive dangerous goods storage floors to prevent electrostatic accumulation requirements; electronic components Production, operating room, food, medicine, and precision machinery production and assembly area clean ground requirements, etc., require specialized construction companies to complete a variety of special ground.

Wear-resistant floor according to the material can also be divided into wear-resistant particles additive type, polymer type. Anti-abrasive particle additive types include non-metallic, metal and alloy particles, wear-resistant ground, used in factories, parking lots, large supermarkets, sidewalks, and roadways, etc. These types of projects can be carried out in the same period of civil engineering ground projects without additional Construction period. GB50037-96 “Specifications for Design of Building Surfaces” lists iron-dusted concrete and cement stone chips as types of wear-resistant particles. Alloy aggregate concrete is not included. Due to the improvement of equipment and processing technology, compressive strength and bending strength And the tensile strength is much higher than the standard value. The technical indicators of the wear-resistant granular additive ground include: compressive strength (MPa, ≥): quartz sand 50, corundum 65, silicon iron alloy 80, silicon titanium alloy 90; flexural strength (MPa, ≥): quartz sand 10 , silicon carbide 10, ferrosilicon 12, silicon-titanium alloy 13.5; tensile strength (MPa, ≥, GB/T16777-1997): quartz sand 3, silicon carbide 3, ferrosilicon alloy 4, silicon titanium alloy 4; wear resistance (gear method , ≤g/cm2, GB9966.4-88): Silica sand 02., Emery 0.18, Ferrosilicon alloy, silicon titanium alloy 0.15; Surface hardness (Mohs, ≥): Quartz sand 7, Emery 7.2, Ferrosilicon 7.8, Silicon-titanium alloy 8; surface resistance (Ω): quartz sand, corundum, ferrosilicon 105-108, silicon-titanium alloy 105-108.

High-molecular polymers are used in surface engineering of high-molecular polymers, mainly including epoxy, polyurethane, vinyl ester, acrylate, and polyurea. The same high-molecular polymers may also be aqueous, solvent-based, and free. Solvent-based, suitable for application in a variety of environmental conditions, can be fiber-reinforced or multi-layer composites with wear-resistant fillers, conductive agents, etc., so that the ground material has good resistance to oil seepage, corrosion resistance, static conductivity, etc. Its surface is hard or elastic. Suitable for various requirements such as mechanical scratch resistance or sports field. Epoxy-type static conductive ground technical indicators (7d, ambient temperature 20 °C) are: compressive strength (MPa, ≥) 85; flexural strength (MPa, ≥) 35; bond strength (MPa, ≥, GB/T5210 2.5 (concrete damage); wear resistance (g/cm2, ≤, GB/T1768) 0.025; surface hardness (pencil hardness H, ≥, GB/T5210) 3; elastic modulus (MPa) 9000; surface resistance (Ω ) 105 ~ 108; chemical resistance is excellent alkali-resistant, medium-density non-oxidizing acid, non-ester, ketone solvents and low concentrations of organic acids.
