"Crack king (KLW-002), polypropylene fiber," Karen Yueda Building Materials Co., Ltd. developed its own production of mortar and concrete special fiber, also known as crack fiber or fiber works, is a poly propylene as the main raw material, high strength monofilament fiber made of a unique production process, adding concrete or mortar can effectively control plastic shrinkage of concrete and mortar, shrinkage, temperature changes and other factors caused by the micro-crack gap, to prevent and suppress the crack formation and development, has greatly improved the cracking impermeability of concrete features, impact, and seismic capacity of the product can significantly improve the mortar, concrete, brittle, mortar, concrete materials, media continuity and uniformity, can effectively reduce mortar, concrete water seepage engineering and industrial and civil construction (wall, floor, pool, basement, etc.), hydraulic engineering (river, dam, wharf revetment, etc.), as well as roads, bridges and other projects (road, bridge airport pavement, etc.), and a variety of concrete products. 
 Polypropylene fiber physical parameters

 Crack king of polypropylene fiber applications 
 1 concrete rigid self-waterproof structure, basement floor, side walls, roof and roof floor, pool, etc.; 
 ② cement mortar, dry mortar, insulation mortar, cracking mortar, interior and exterior plastering mortar, putty powder; 
 ③. Crack resistance, impact resistance, abrasion resistance, earthquake and other requirements of the occasion; 
 ④. Deck, piers, ports, water conservancy and other. 
 Crack king of polypropylene fiber construction process 
 Concrete, mortar cracking impermeable dosage was 0.91 kg/m3, "crack king (KLW-002), polypropylene fiber," usually specifications for 19mm (specifically require the use of design drawings), did not specifically require the mixing equipment and construction technology construction, with the crack king of polypropylene fibers in mortar and concrete to be dispersed evenly than directly to the crack king of polypropylene fibers into the mixer, as long as an appropriate extension of the mixing time (dosage according to the design drawing requirements and construction requirements of the specific increase). 
 This product can not replace structural materials to strengthen, not reduce the principal size alone can not solve the settlement of mass concrete water heating and a strong external momentum of the occasion, you can not reduce the quality of construction because of the use of the fiber should be the national technical specifications construction and maintenance.
