Urban roads are prone to cracks and collapse due to repeated rain, heavy pressure, repeated rolling and other harsh loads, which affect the traffic efficiency and aesthetics of urban roads. In particular, cracks and collapses are more likely to occur around manhole covers in urban roads.
In the process of repairing urban roads, in order to shorten the construction period as much as possible, so as to achieve rapid repair and rapid opening to traffic, so as to achieve good and efficient traffic efficiency.
To this end, on the basis of UHPC ultra-high performance concrete, a fast-hardening UHPC road repair material is compounded to enable rapid construction, and it can be opened to traffic 2 hours after construction is completed. It can also be used on highways and ordinary roads for quick repairs.
UHPC is the abbreviation of Ultra High Performance Concrete, also known as Reactive Powder Concrete RPC, Reactive Powder Concrete.
On this basis, adding quick-setting components can realize the compounding of quick-hardening UHPC road repair materials.
Amorphous calcium aluminate is currently the world's leading active powder quick-setting material. It has the following advantages: high activity, ultra-rapid setting, ultra-low alkalinity, ultra-early strength, ultra-low drying shrinkage, impermeability, and high adaptability, etc.
Ingredients
Portland cement, sulfoaluminate cement, amorphous calcium aluminate, retarder, polycarboxylate superplasticizer, micro silica fume, fly ash, steel fiber, HPMC, etc.
