Concrete additives are materials that are added before or during mixing to improve the new properties of fresh concrete and hardened concrete. The amount of admixtures is less than 5% of the cement quality.
Concrete accelerator is an admixture for the use in concrete, mortar, rendering or screeds. The addition of accelerator speeds the setting time, and thus cure time starts earlier. Development; not only has the function of early strengthening but also has the process of reducing water and enhancing.
Concrete hardening agent is one of the substantial admixture varieties used earlier in the development history of admixtures for concrete. Cement quick-setting agent is a concrete admixture that makes cement concrete set and hardens quickly.
Self-leveling mortar is a dry-mixed powder material composed of multiple active ingredients, which can be used by mixing water on site. After a slight spread of the scraper, you can get a high-level base surface.
Foam concrete density is about 500-1200 kg/m3; thermal conductivity is generally 0.12-0.30 W/(m·k).The compressive strength is generally 3-14 MPa, and it is often used as an insulation layer for roofs, self-supporting walls, and thermal pipes.
Foam concrete insulation board and organic foam insulation board are the most commonly used new insulation materials, but there are differences in heat conduction.
