Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, the main structure of the detection area down the river, it 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, the main structure detection, detection walls, roads and bridges detection, detection of a number of civil air defense projects testing qualification and testing Lab. Non-active material in the cement mix regulate cement strength grade, saving of the cement clinker, also known as mixed filling material. Such hybrid material, the main structure Yuwangtai zone detection, firm texture are ground into a fine powder quartzite, limestone, sandstone; soft texture are clay, loess and the like. Also, who do not meet the technical requirements of granulated blast furnace slag, pozzolana and fly ash mixed material, can be used as non-active mixed material applications. For non-active blended material quality requirements mainly be of sufficient fineness, no or very little cement containing harmful impurities. 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, detection QiXian main structure, wall detection, detection of roads and bridges, air defense projects to detect a number of aptitude test and testing laboratories. The yield strength detection principle is to use the yield phase force substantially constant range of fluctuation in the calculated value of the unit at this time of stress on the cross-sectional area (ie yield strength σs); tensile strength of steel pulled off when using a corresponding one of the largest stress, stress values ??calculated at this time on the unit cross-sectional area (ie tensile strength σb); elongation δ is the percentage of steel pulled Elongation length accounted original length. Jinming District, the main structure of the detection _ malpractice detector (Online) _ The main structure is detected by the increasing prevalence of Construction Engineering Testing Co., Ltd., Henan.
