PRECAST CONCRETE Materials, Manufacture, Properties and Usage

With the exception of admixtures and fly ash, all moulds and materials
are discussed in this chapter. None of the factors listed can be considered
in isolation since variation in one will often affect another. Mix design
for various forms of precast manufacture is dealt with in Chapter 6. The
purpose of this chapter is to acquaint the reader with all the starting
variables. The background picture will then be fully understood before
one proceeds to put these variables into a process, in order to produce a
precast concrete product.
