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, 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, the water, the better the material, sometimes water resistance is an important basis for selecting materials. Important structures are often located in water or moisture is serious, 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, engineering test and monitoring, material softens coefficient of not less than 070. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, quality engineering 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. Mineral material having pozzolanic natural or artificial, called pozzolana mixed material. The so-called pozzolanic, refers to a material that is ground into a fine powder, engineering test, water alone does not have the hydraulic mixing, but at room temperature with a small amount of lime water, etc. can be formed with hydraulic properties of the compounds. Pozzolanic material contains more active SiO2 and Al2O3, they can and Ca (OH) 2 at room temperature from a chemical reaction, respectively, to generate hydrated calcium silicate and hydrated calcium aluminate, which has a water hardness.
