REPAIRS TO FIRE DAMAGED STRUCTURES
The author considers the effect of fire on structural quality concrete, reinforcing steel and pretensioning tendons and the effect on structural members. The need for propping is discussed. Reference is made to Concrete Society technical reports nos. 15 and 26 which give more detailed recommendations. Preparation for repair involves cutting away deteriorated concrete back to sound material, provision of a suitable profile, cleaning and roughening of the surface. The method of placing the repair material can be by recasting in formwork, spraying (graniting) or by hand-applied mortars. Each method will give satisfactory results, providing the specification, materials and techniques are appropriate and the work competently done by experienced operatives. Choice will therefore depend on practical and cost considerations. Spraying or re-casting will be found most suitable for large volume, large area applications, and where speed is important. Hand-applied mortars will be most suitable for patch repairs and lesser volumes. (TRRL)
