Introduces three different methods were used to detect the intensity of grouting material - Henan grouting material manufacturers

grouting material strength high strength grouting material strength of MCC CGM high-strength non-shrinkage grouting material strength grouting material after years of effort, the construction of marketing network throughout the country, healthy and vigorous marketing team, adhesives are both grouting materials and products, through the market, get the user's recognition, are inseparable with the giant tyrone pay link, small make up to you to introduce the grouting material strength testing of three ways: first, the rebound method is through the rebound hammer determination of grouting material surface hardness to determine the strength of grouting material, it has the characteristics of simple, sensitive, but the precision is relatively poor, and needed a must strength curve, for some special molding process or special parts of the grouting material need a special strength curve can detect. When grouting material surface and internal quality have significant differences or internal defects, such as surface roughness, suffering from chemical corrosion or suffering from frostbite, etc. , during the fire, hardening is not with the rebound method. When choosing rebound method for testing, the surface shall be the same grouting material surface, and should be clean, smooth, there should be no loose layer, bleeding, voids, pits and grinding wheel should be used when the springback to remove loose layer and sundry, and should not have the remaining dust and debris. To flick it produces vibration of thin wall and small components should be fixed. Second, ultrasonic method for ultrasonic testing is by low-frequency ultrasound instrument, measurement of ultrasonic longitudinal wave in the structure of the grouting time, the first wave propagation speed and the received signal frequency acoustic parameters, such as changing grouting guess of the defect status, can internal vague and imperfect zone of grouting material, crack depth and location, appearance damage layer thickness, the different time pouring grout joint surface quality and the grouting material for making accurate judgement of homogeneity, it is just what other detection method cannot. Therefore, the ultrasonic method has been widely used in engineering detection. With ultrasonic method testing strength of grouting material, because there are many factors which can affect the sound velocity, when the dataset, moisture content and age is not at the same time, the transmission speed and strength of grouting material contact will have very big different, therefore, the superfine cement grouting material price only by ultrasonic method is difficult to guarantee the accuracy of the grouting material strength tests. Is often the method of ultrasonic and rebound method together to determine the strength of the grouting material, is the ultrasonic rebound synthetic method. Third, the core method is the basic principle of the typical structure of grouting material on the drill core samples and make the necessary after finishing the compressive strength test, every age period of not less than 14 d strength of not less than 10 mpa measure the strength of grouting material can choose core method, but because after linger-sometimes constantly the damage to the structure formation must, therefore, about security is inherently lack or damage of structure and component of planning is needed on party agreed to, can choose the way. On the part of the core, quantity, and the scale of the faith have detailed rules. Core method is a kind of secure directly, and can well reflect the status of grouting material actual damage detection method. On the various nondestructive tests are difficult to measure precise strength grade of grouting material strength, this method can more accurately determine the strength of epoxy resin grouting material price from core samples can directly observe the internal part of the grouting material conditions, such as the distribution of aggregate, the size of the cracks, etc. The way is suitable for grouting material (more than several years of long age or freezing injury, fire, chemical corrosion, such as detection of damaged components, but this way the intensity of labor is big, the study of structure will form some part of the damage. You may suddenly enlighted, see the above analysis, the grasp of the characteristics of the each test method, is more advantageous to you in a different condition sensitive use of main basis is the structure of the grouting material and the surrounding conditions of a detailed analysis, core method has priority claims under conditions permit; Core method also can improve the accuracy of the rebound method and ultrasonic rebound method.
