Engineering Fiber

The origin of synthetic fiber's applicationIt's well-known that concrete is the man-made building material used most in engineering at present. However, there are some defects of it, such as easy to plastic constrain and crack, weak tensile strength, bad tenacity, etc. that affect engineering construction. The crack of concrete is ubiquitous that affect not only the rigidity and appearance, but also the endurance of concrete. Rigidity is generally taken as a standard to weigh the material's quality in common concrete project. But those concrete in accordance with design standard of rigidity fail to work in using period designed for inner crack extension or external environment factors. This so-called destruction of endurance often results to accidents or a lot of repairing charge. Small cracks in concrete are also the direct reason of weak tensile strength and many destruction of endurance. Plastic constraint and cracking of cement concrete has been a tough matter in projects as it often occurs during checking and acceptance period of project, greatly affects project quality and is difficult to deal with.Among many techniques for controlling cracks in concrete, mixing fiber in concrete is an effective way to strengthen and prevent it from cracking. International engineering circles have been researched on using synthetic fiber to solve cracking of concrete since 70s of last century. USA and Canada applied it earliest, then, it has been popularized to Mexico, Australia, Japan, South Korea and southeast countries. Synthetic fiber has been applied in many civil engineering and architecture projects in middle 90s of last century in China.Main functions and application of synthetic fiber:strengthen inner tensile strength, reduce retraction capability of inner capillarycontrol forming of plastic constraint cracks or settlement cracks.improve impact resistance, anti-wearing and breaking resistance.advance tenacity, impermeability, fatigue resistance, anti-frozen and anti-melting capability and anti stripping capabilityimprove crack resistance in low temperature, stability in high temperature and water stabilitySynthetic is mainly applied in the following fields:Industry and civil architecture projectsRigid waterproof, thin concrete structure, such as basement, roof, pool, water ditch, digestion tank, etc.Mortar of anti-cracking and anti-seepage, such as mortar for float coating and heat preservation and insulationLarge concrete, such as crossbeam of conversion layer, floorslab, abutment, etc.Structure that easy to wear, such as parking lots, parking apron, roof for people standing on.Injecting concrete, mortar.Road and bridge projects: such as bridge surface, surface of highway and express highway, etc.Water conservancy and harbor engineering, such as large dam body, faceplate, harbor and so on.Precast concrete products and component, such as guidance tape of highway, various pipe, precast slab, new brick of wall and so on.Surface repairing projects, such as repairing of bridge surface and road surface.
