Abstract:
Probably 95 of every 100 instances of concrete disintegration can be traced definitely to bad aggregate, bad mixing, or bad placing. Maintenance and restoration procedures are discussed in general and various methods are described which include the plaster method, gravity placed concrete brush-applied cement-sand washes, and the pressure-concrete method. Other details covered are: proper base, mesh reinforcement, cracks and joints, mixes, aggregate, pressure for shotcrete finishing, curing, weeps, and integral waterproofing.
