Baotou GRC It is a new type of building material. The specific material characteristics are not very clear in some places, Baotou EPS Let's introduce GRC The specific characteristics of GRC materials enable people to better understand and use GRC materials.
(1) Lightweight - GRC material has a unit weight of 1.8-2.0T/M3, which is 1/5 lighter than reinforced concrete. Because it can be made into thin-walled hollow products, the weight of GRC material is significantly lower than that of solid products.
(2) High strength -- after adding glass fiber, the bending strength of cement mortar increases from 2-7MPa to 6-30Mpa. In addition, the product section is mostly hollow surface, with large inertia moment and high bending strength.
(3) Good impact resistance toughness - because a large number of glass fibers penetrate the GRC material, it can absorb the energy of impact and improve the impact resistance. The domestic test results show that the impact strength is increased from 1-2Kg CM/CM2 to 5-15Kg CM/CM2.
(4) Good impermeability and crack resistance - because a large number of fine and dense surfaces of glass fiber are evenly distributed in all parts of the product, a mesh reinforcement system is formed, which delays the appearance and development of cracks, reduces stress concentration, and improves the impermeability and crack resistance.
(5) GRC material is water resistant, fire resistant, and has good processability and moldability.
