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. In construction, in order to improve the durability, building walls to detect the material, the material may take the following measures in accordance with its own characteristics and causes of corrosion. a material in the production process: ① reduce internal porosity of the material, especially the open porosity; ② reduce material number and length of internal cracks; ③ the internal structure of the material homogenization; ④ multiphase composites should increasing the interfacial bond strength between the walls testing costs, such as concrete, stone walls testing should be increased adhesive force of sand, stone and cement between.

Mineral material having pozzolanic natural or artificial, called pozzolana mixed material. The so-called ash sex, refers to a material ground into a fine powder, mixing with water alone does not have the water hardness, but at room temperature water with a small amount of lime can be formed with a hydraulic properties of 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.
