SY-K expansion of fiber cracking waterproofing agent factory price - contact Shun Li Industrial 13,331,056,879 18,311,209,002 build Beijing Shun Industrial Engineering Technology Co., Ltd. supply construction materials to order please call 13331056879 Li main specialty dry mortar, bridges duct grouting, grout, grout reinforcement, building waterproof materials, road repair materials, concrete anti-corrosion additives, polycarboxylate superplasticizer, not angry mortar, anti-static, such as cement and construction program for more product information, technical data FEA fiber expanders JEA-A fiber bulking agent GB-A fiber expanders SK-A fiber expanders SY-K expansion of fiber cracking waterproofing agent JK-HEA fiber expanders JS-HEA fiber expanders SG-A fiber expanders JK-QF fiber expanders, SY -CMA First, the scope: SY-CMA expansion of fiber cracking waterproofing agent (referred to as "fiber expanders") as a powder, is based on ordinary cracking waterproofing agent added polypropylene fibers, the tensile strength of the concrete toughness, impermeability, crack, etc. have significantly improved effect; reduce microfractures solid concrete or mortar plastic shrinkage, shrinkage, temperature changes and other factors, greatly improving the impermeability of concrete crack resistance, impact resistance and seismic capacity. This product is a micro sulphoaluminate expanders, polypropylene fiber, a variety of organic and inorganic waterproofing agent composite materials, widely used in underground waterproofing crack, long structural engineering, civil air defense projects, highway pavement, tunnels, ports, water plants, power plants, dams, with special impermeability Blast military projects. Second, the mechanism of concrete in the hardening process, the reaction of cement hydrates and water, causing the concrete volume shrinkage, and since the late concrete free water evaporation caused by drying shrinkage, shrinkage stress exceeds the tensile strength of the cement matrix will produce micro-cracks in the concrete. Development of micro-cracks is about 70% complete at 3-7d gel during this time is less than the tensile strength of concrete 1Mpa. After adding the expansion of fiber cracking waterproofing agent in concrete, cracking waterproofing agent to compensate for shrinkage of the concrete to harden and shrink process, the fibers are uniformly dispersed in the concrete to form a support system to chaos, dispersion directional stress of concrete prevent early onset and development of cracks in concrete plasticity, greatly improving the impermeability of concrete put cracks and improve the toughness of concrete, thus extending the service life of concrete. In addition, as the fiber itself has a certain strength, the fibers are uniformly dispersed and anchored in concrete form, which then can absorb some damage instant energy, helps cut concrete plastic shrinkage and stress during freezing and thawing. Meanwhile, many fiber filaments can effectively hinder added aggregate segregation, to ensure that the early uniform bleeding of concrete, thereby reducing the formation of settlement cracks. Third, the performance characteristics of a fineness ≤15% (0.08mm sieve residue); 2, fiber dimensions: length 6-9mm; 3, setting time: the same as the reference concrete; 4, to improve crack resistance, particularly to improve concrete early crack resistance, compared with the reference concrete reduced by 60% -80%; 5, to improve impermeability, penetration height ratio ≤40%, impermeability grade up to S20; 6, improve impact resistance and abrasion resistance, and the benchmark more than 50 percent increase compared to the concrete; 7, improve frost resistance, frost numbers D100 up above; 8, increase the fire resistance of concrete, improve anti-knock function, compared with the reference concrete increased by more than 20%; 9, to improve concrete quality products; 10, chlorine-free products, non-toxic, harmless, no corrosion of steel, environmental pollution. Fourth, according to the standard: JC474-2008, GB23439-2009, GB / T50082-2009 ;; five, using methods and precautions 1, Volume: 6-8% (within the mixed amount of cementitious material); 2, due to the product is doped fiber components, will increase the viscosity of the concrete mix, so that the degree of collapse fall slightly reduced. Each project requires a different slump, so before the test works by regulating the use of slump, slump can not meet the construction requirements if yes, do not increase the amount of water applied to increase the slump, but should be appropriately used plasticizer or reducing agent to increase the slump to meet construction requirements. 3, stirring time than ordinary concrete extension of 60S, to ensure that the fiber can be mixed in the concrete. 4, concrete hardened to timely maintenance, the concrete while maintaining a moist state. VI, packaging and storage: This product 50kg / bag, should be stored in a cool dry place to prevent moisture, damage, shelf life of one year.
