Grouting material models of positioning and selection

grouting type high strength grouting material model CGM high-strength non-shrinkage grouting material model high performance grouting material model applied modern grouting material model of science and technology, the grouting material models of production process and application of green; Reduce the dosage of cement; A large number of using industrial waste residue, alternative aggregate; To reduce the noise pollution in the process of production, dust pollution, etc. ; More use of grouting material type and construction waste, waste reducing environment load; High performance grouting material model, treasure more grouting material model of long service life, for some special parts of the special project, control structure design is not the strength of the grouting material model, but the durability. Can make grouting material model structure is safe and reliable work 50 ~ 100 years, reduce maintenance costs. These are the use of grouting material model, Shanghai grouting material model this traditional materials known as green material, key measures to use for a long time. High performance grouting material type is a concrete way of sustainable development, is the direction of the development of cement base material, is the breakthrough of traditional concrete, section in saving energy, material, engineering economy, labor protection and is of great significance in such aspects as environment, is a new materials, environmental protection, intensive can be referred to as the 'green concrete'. High performance grouting material model is one of the important direction of grouting material type green production. On the international at present has been widely recognized that high performance grouting material type instead of the traditional grouting material model, Shanghai grouting material model structure and build in the harsh environment of the special structure, with remarkable economic benefit. Use to help owners and construction units more clear understanding of different models of type grouting material corresponding scope of application, the grouting material have more models corresponding to know zhangjiakou anti-freezing type grouting material model, we explain in detail below what circumstance should choose super early strength type grouting material type? For the following we list a few industries, the owner and installation company of technical personnel, meet the following conditions, it is recommended to use super early strength of grouting material model, avoid to use ordinary grouting material model, appear a series of unnecessary trouble. A: civilian industry without shrinkage requirement of equipment foundation grouting, especially under the condition of high load and impact delivery charge; 2: rolling mill of anchorage steel and aluminium industry, punching machine, wire drawing machine and finishing mill; 3: the anchoring turbine, generator, pump and turbine centrifugal compressor; Four: anchor grouting material H guangzhou model factory steel column, steel pipe; Five: the transportation rail, crane rail bolt in the transportation sector, the runway lights; Six: industrial conveyor bearings, pipes, bearings in construction industry; Seven: used in coal mine conveyor belt, transmission tower in the energy industry. Meet the above several ways, if use normal grouting material model, strength reach, load too fast, strength of grouting material model rise slowly, even has certain strength rise, but strength is not standard, the section of concrete damage, the serious problem such as craze, cause safety accidents, it is not allowed.
