Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, Lushan pile testing organization, is one of the qualification place in Henan Province since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, Jiaxian pile testing agencies detect walls, roads and bridges detection, detection of a number of civil air defense projects Detection qualification and testing laboratories. Material that is outside the friction material mass and volume loss caused by the phenomenon known as wear and tear. Material by both friction and impact the quality and volume of the two effects caused by the phenomenon known as the abrasion loss. Building for the ground, stepping, steps, pavement materials, etc., should give due consideration to wear; pavement materials used in road works, must consider the wear and abrasion resistance performance; hydraulic engineering, such as overflow dam overflow face, sluice and concrete floor and other parts, Wolong pile testing organization, often by flushing of the high-speed stream of entrained sand or gravel bottom entrained flow impact action and destruction, these areas need to be considered material to resist abrasion and wear performance . Greater hardness, high toughness, more dense structure in real time, its strong resistance to wear and abrasion. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, pile testing, qualification, Henan Province is one place since the first detection through examination of business. Business in the Pile qualification qualification, the qualification grade steel, a qualified indoor environment, building energy efficiency testing, subject testing, materials testing, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Not only the size of the material moisture content and material porosity and pore size structural features, but also with the surrounding air temperature, humidity, and when the air humidity and low temperatures, the moisture content of the material is large. Material moisture and humidity of the ambient air balance, when the material is air dried state. Material in the moisture content of air-dry state, called the equilibrium moisture content. Equilibrium moisture content is not fixed, it change with the ambient temperature and humidity change. Wolong District pile testing agencies, the increasing prevalence of detection means (certified), pile testing provided by the Construction Engineering Testing Co., Ltd. Henan malpractice. Henan malpractice Construction Engineering Testing Co., Ltd. (www.hnrsjc.cn) (www.rsgcjc.com) is a leader in Zhengzhou, construction, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, the maximum to meet customer needs.
