Abstract

The super thin fast repair material for highway and airport runway consists of early strengthened hydraulic cementing material 30-90 wt%, polymer resin emulsion or water dispersible polymer powder 0.1-40 wt%, fine sand 8-60 wt% and inorganic modifier 0.1-15 wt%. The repair material is suitable for thin layer and super thin layer repairing of concrete and asphalt road surface, may be also used for repairing damaged part when sand, crushed stone and other aggregate are added. It is also suitable for repairing inner and outer walls of building. The finishing super thin cement mortar layer has the breaking strength reaching 2-4 MPa in 2-3 hr and compression strength up to 20-30 MPa. The present invention can raise the antiwear performance, weather resistance and engine oil and hydraulic oil corrosion resistance.

Description

1. Technical field [0001] The invention relates to a building material for road maintenance, in particular to a building material for fast repairing of the thin layer and ultra-thin layer on the surface thereof, more precisely, a material for quick repairing of the ultra-thin layer on the surface of roads and airport runways. 2. Background technology [0002] The surfaces of airport pavements, high-grade highways, bridge pavements and industrial buildings are mostly concrete or asphalt materials, and the surfaces need to be repaired and maintained during use. For example, repairing cracks or damages, and in most cases, repairing and maintaining the surface with thin or ultra-thin layers. Its patching or restoration requires rapid curing in order to keep traffic flowing. The thickness of the overlay restorative layer changes gradually with the progress of materials science. For traditional concrete, the standard of the US Department of Transportation in the early days was &...
