Abstract

The invention discloses a composite compacting agent which comprises the following components in percentage by weight: 30.0-40.0% of a corrosion-resistant component, 25.0-35.0% of a double-expansion source clinker, 15.0-20.0% of gypsum, 5.0-10.0% of a polymer modifier and 5-15.0% of an ionic curing agent. By adopting the composite compacting agent disclosed by the invention, the sulfate resistanceand the seawater corrosion resistance of concrete can be well improved, sulfate ions and harm ions of chloride ions in the concrete can be immobilized, and the service life of engineering in a harshenvironment can be prolonged. The composite compacting agent disclosed by the invention is a composite compacting agent product applicable to corrosion resistance and high air tightness of concrete incomplex environments.

Description

technical field

[0001] The invention relates to a compacting agent, in particular to a composite compacting agent, in particular to a composite compacting agent suitable for corrosion resistance and air tightness of concrete in complex environments, and belongs to the technical field of building materials. Background technique

[0002] my country is in the midst of large-scale construction, and concrete materials and structures are used in a large number of bridges, tunnels, water conservancy and hydropower, nuclear power, marine, civil construction and other projects. Among them, many projects under construction and to be constructed are in complex environments, including Hong Kong-Zhuhai-Macao Bridge, Bohai Bay Tunnel, South China Sea Island Reef Airport, Qinghai-Tibet Railway, Lanzhou-Xinjiang High-speed Railway, etc. Concrete structures will face serious durability problems in these complex environments. For example, during the construction and use of high-speed railway ...
