STRUCTURAL REPAIRS

In order to repair concrete that has suffered damage due to the penetration of water, salts or carbon dioxide, it is suggested that in general the use of concrete and cement-based repair materials is preferable to resin-based alternatives due to their structural and thermal compatibility with the parent material. Cementitious-based repair materials can be divided into three basic groups - concretes and grouts, which are placed in formwork, and trowel applied mortars. Although replacement mixes should preferably have similar properties to the original concrete, modifications may be necessary where the existing concrete has proved inadequate to prevent environmental penetration. It is emphasised that repair of reinforced concrete with a concrete mix requires a specialised technique to overcome problems during placing, compaction and setting operations. (TRRL)
