reinforced fiber cement board

The abbreviation of GRC is reinforced fiber cement boardwhich traced back to the 70s of 20th century,which is a new kind of inorganic composite material which is made of alkali fiberglass as reinforced material and sulphoaluminate low-alkalinity cement as the base material (hereinafter referred to as cement) through jeting,casting vertically,extrusioning,slurrying and doing other process stream.the main material introduction Compared to other cement,the strength and high strength performance of sulphoaluminate low-alkalinity cement is particular prominent,especially for more than 3 days,its strength can reach 10Mpa, and the maintanance period is longer,the strength is grower,while the freeze resistance and anticorrosive property is better than other cement.For high frost resistance, the early strength is 5-6 times to that of Portland cement in the 0-10 lower temperature,if adding a small amount of 3d-7d admixture,the strength will meet the design label of 70-80% in the 0-20 temperature, freeze-thaw cycles 300 times the strength loss is not obvious.For high impermeability,cement paste structure is dense,concrete impermeability is the same label Portland cement 2-3 times,anti-carbonation of performance is good,shrinkage is low,the performance of corrosion resistance is good,especially seawater corrosion resistance is superior to high sulfur resistant Portland cement,anti-corrosion factor is greater than 1. Alkali fiberglass,also known as AR fiberglass,English name:alkali-resistant fiberglass,the fiberglass woben fabric is as the substrate,which is made by molecular alkali emulsion (such as ZrO2),mainly for the rib reinforcement material of glass fiber-reinforced concrete (referred to as GRC),which is an ideal substiture for asbestos and steel.It is characterized by good alkali resistance,being effective against the cement Ca(OH)2,owning the following performance:the continuous erosion of the bond strong, impact resistance, tensile, high strength bending,non-combustible,antifreeze,anti-temperature,humidity capability,crack resistance,impermeability,widely using in high-performance reinforced concrete,also belonging to a new type of green environment-reinforced material. The test results indicate that its aging reaches 80 years after the composite of the alkali-containing zirconium oxide and low-allkali cement. II GRC product feature Light--The capacity of GRC material can reach 1.8-2.0T/M3,lighter than steel 1 / 5 as it can be made into thin-walled air system products,whose weight is a significant reduction than the physical products Strength--After adding alkali glass,the flexural strength of sand paddle can reach 6-30Mpa from 2-7Mpa Good toughness--As a large number of fiberglass are used in GRC material,it is able to absorb the impact energy,improce impact resistance,national test results show that the impact strength can reach 5-15Kg/CM2 from 1-2Kg/CM2 cracking performance--Due to a large number of fiberglass which are distributed evenly in all parts of the body,forming a network to enhancing system,delaying the emergency and development of cracks, reducing the stress concentration phenomenon and improving impermeability crack resistance water-resistant fire-resistant--GRC materials can be water-resistant and fire-resistant and have good processability and plasticity Good acoustic effect--Sound reflection coefficient of 100Hz-4KHZ is 1.00-0.97 Construction easy to install short period to install Cetification: Our company has passed ISO9001:2000 international quality system certification in 2005.The company has obtained CCES registered trade mark approved by State Trademark Bureau in 2007.The access panel produced by company has obtained letter of patent approved by State Patent Office in 2008 .We have obtained Perfect Brand of GRGGRCand other gypsum products by The National Committee of Hi-Tech Building Materials Industry in 2009. Another,we also obtained Eviromental Protection of Building Material.The products has inspected by National Fire Equipment Quality Supervision and Inspection Center,Shanghai Construction & Science Institute, Institute of Acoustics of Tongji University and Shanghai Environmental Quality Supervision Station, all the indexes equal to or surpass those of same industry or the national standard.
