Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, 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, Luanchuan Engineering Test Center, curtain detection, detection of roads and bridges, air defense projects to detect a number of aptitude test and testing laboratories. Usually when the aqueous material, the intensity has decreased. This is because the material bonding force between the particles is caused by infiltration of water molecules weaken. If the material is easily dissolved in water containing some or softened materials (e.g. clay, gypsum, etc.), the strength is lowered more serious. Softening coefficient larger engineering testing, materials, water resistance, the better, sometimes water resistance is an important basis for the choice of materials. Often at or severe damp important structural water softening coefficient of the material should not be less than 085, such as bridge structure located in water pier caps, etc; damp lighter structures or secondary structures, materials, softening coefficient of not less than 0 70.

Calendering is the ingot (or steel) at room temperature or under heating conditions, Song County engineering test center for the steel rolling process to change the shape of the craft. After the steel after rolling, and their microstructure and mechanical properties will change. Heat treatment is the steel for process heating and cooling process in order to achieve the purpose of improving the organization and performance of steel. Changes latency and processing steel in the hot and cold processing performance occurs, aging called hardening steel.
