Several building materials that can be used for rapid repair of airport runways:
1. Amorphous calcium aluminate is a new type of special concrete quick-setting material. Its core advantages lie in its super-fast setting, low shrinkage, anti-seepage, low temperature resistance, high activity, high adaptability, low alkalinity, high early strength and high strength, is currently a relatively perfect road repair material in the world. In the material adaptation with cement-based concrete, no loss of strength in the later stage can be achieved.
2. Steel fiber has a good effect on preventing the crack expansion of hardened concrete, can improve the tensile strength and toughness of concrete, and improve the frost resistance, impact resistance and fatigue durability of concrete. In highways, airports and other pavement projects, steel fiber reinforced concrete can prolong the service life of runways.
3. Calcium Sulphoaluminate cement has the advantages of rapid hardening, early strength and high rigidity, and can be used as the basic material for rapid repair materials.
4. Silicon carbide material, can enhance the wear resistance and impact resistance of concrete floors. Greatly increase the density of concrete, reduce dust, increase the oil resistance of the ground, and form a high-density, easy-to-clean, impermeable ground. Constructed together with the concrete ground, the construction period is short and the durability is good.
