Pavement thin layer rapid repair material

Abstract

The invention belongs to the field of special materials of building materials, especially to a pavement thin layer rapid repair material, and the material is extensively applicable to concrete pavement thin layer rapid repair of projects like an airport, a road, a highway, a bridge, a port and a wharf. The pavement thin layer rapid repair material provided by the invention comprises the following raw materials by weight: 100 parts of an epoxy resin, 10 to 35 parts of a curing agent, 100 to 600 parts of fine aggregate and 100 to 500 parts of a toning modifier. The pavement thin layer rapid repair material provided by the invention has the following advantages and beneficial effects: high strength, fast development, excellent bond performance on cement concrete, a great adjustable scope of setting time, capacity of rapidly recovering use functions of a cement concrete pavement, excellent frost resistance and deicer scaling resistance, high abrasion resistance, high performance in protection of a steel bar from rust, small drying shrinkage, high crack resistance and adjustable colors in accordance with requirements.

Description

technical field [0001] The invention belongs to the field of special materials for building materials, and in particular relates to a pavement rapid thin-layer repair material, which can be widely used in rapid repair of concrete pavement thin layers in projects such as airports, roads, highways, bridges, ports and docks. Background technique [0002] In recent years, it has been found that concrete damage in civil engineering such as airports, roads, and bridges is increasing, resulting in huge direct and indirect economic losses. The reasons are not only the harsher environmental conditions and the poor durability of concrete during design, but also factors such as insufficient construction management, blind pursuit of progress, and even cutting corners. Therefore, in order to restore the function of these concrete structures and ensure the safety of use, they must be repaired in time. [0003] In these destructive projects, concrete surface erosion or damage is the most ...

Problems solved by technology

However, although these materials set and harden quickly and have high bond strength, they are expensive and do not match the material properties of old concrete, such as thermal expansion coefficient and color, etc.
