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, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories. Usually when the aqueous material, Yiyang engineering test center, 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 greater, better water resistance materials, engineering testing, sometimes the 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. 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, Xin'an Engineering Test Center, curtain detection, detection of roads and bridges, air defense projects to detect a number of test qualification and testing laboratories.  in the course material: ① increase in surface protective layer, such as brushing paints, coatings, Yichuan Engineering Test Center, plaster, etc.; ② reduce the corrosive effect of the external environment, such as the exclusion aggressive substances, lowering the temperature, etc. ; ③ improve the density of the material itself, such as concrete vibrators method to pay attention to the selection and mixer.
