We do the ground, the temperature and humidity requirements are very strict, no matter Emery wear or cement concrete ground floor are the same, especially temperature. Like now this season, the weather is cold, relatively low temperature, the temperature in the end what it was suitable for the ground? In principle, the average temperature for 5 consecutive days and nights of not less than -5 ℃ or minimum temperature not lower than -15 ℃, the before construction, construction in the winter if you must, then, need to make insulation measures Emery wear material advantages, concrete which should add what Emery Abrasive ash cents, or R-type cement, which will adding some early strength agent, antifreeze, to protect normal construction Emery wear winter ground or concrete floor. Concrete layer in the process of construction of the summer, we should always control the temperature difference between the surface of the impact with the outside world and the temperature difference between the inside and the concrete surface of the concrete; especially before construction on the site of the need for proper pouring temperature treatment - on the ground sprinkler processing ( but not water); prevention of fractures due to excessive temperature caused. Construction of concrete relations with decisive effect emery ground. So Emery wear agents in the process of construction materials, especially in the summer, is particularly important. The point is that the actual temperature and pouring from a reasonable height to determine the slump of concrete, while stressing: non-random add water at the construction site, is strictly prohibited lubrication mortar poured into the concrete structure. Emery wear material prices, Zerui new materials manufacturers (certified), Emery wear material provided by New Material Technology Co., Ltd. Shandong Zerui. New Material Technology Co., Ltd. Shandong Zerui (www.maidiping.net) is Dongying, site construction materials leader, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs.
