Abstract:
Recommendations are made for the application of steam at atmospheric res-sure to accelerate the curing of concrete products. The effects of h atmosp eric steam curing on the properties of concrete as discussed briefly. The current practices in applying this method of curing to precast concrete products, including concrete masonry units, several types of concrete pipe, prestressed and conventional reinforced structural units, and other miscellaneous items, are outlined for each product. General recommendations are given regarding construction and use of kilns, hoods, and other enclosures; layout of plant and piping; orientation of steam jets; and temperature recording and controlling equipment.
