Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, Fangcheng pile testing organization, 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. Material that is outside the friction material mass and volume loss caused by the phenomenon known as wear and tear. Material by both friction and impact the quality and volume of the two effects caused by the phenomenon known as the abrasion loss. Building for the ground, stepping, steps, pavement materials, etc., should give due consideration to wear; pavement materials used in road works, nanzhao pile testing agency must consider the wear and abrasion resistance performance; and hydraulic engineering, such as roll overflow surface, sluice and concrete floor and other parts of the dam, often by scouring effect of high-speed stream of entrained sand or gravel bottom entrained flow impact action and destruction, these areas need to be considered material to resist wear and abrasion performance. Greater hardness, high toughness, more dense structure in real time, Xixia pile testing organization, its ability to resist wear and abrasion stronger. Henan malpractice Construction Engineering Testing Co., Ltd. is a professional testing company, pile 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. Pozzolanic material varieties are many natural volcanic ash, tuff, pumice, zeolite rock, diatomaceous earth and diatoms stone; artificial are calcined coal gangue, shale burning, burning clay, cinder, slag and other siliceous . National standard "for cement Pozzolanic material" (GB / T47-2005) provides Pozzolanic material SO3 content shall not exceed 3%; pozzolan test must be qualified; pozzolan cement mixed with 30% of the mass of mixed materials Mortar 28d compressive strength of Portland cement and 65 mortar 28d compressive strength ratio of not less than 062. For artificial Pozzolanic material, but also the provisions of its loss on ignition shall not exceed 10%.
