THE USE OF BY-PRODUCTS IN CONCRETE
This paper evaluates the use of industrial by-products and waste materials for use in construction. The following by-products are included in the evaluation: blast furnace slag, steel slag, colliery spoil, china clay waste, slate waste, waste from coal burning power stations, by-product calcium sulfate, residues from directly incinerated refuse, and several other miscellaneous wastes. The existing knowledge on the present utilizations of these materials as aggregates or cements in concrete is described and future prospects are discussed. For all materials the following stages constitute the technical assessment: (1) determination of physical properties; (2) chemical analysis; (3) mineralogical examination by microscopy and X-ray analysis to identify compounds present; (4) stability tests; (5) use in concrete as aggregate or cement followed by tests of the concrete for strength and durability; (6) assessment of the life of steel reinforcement in the concrete containing the by-product; and (7) determination whether the material can be used directly, or after heat treatment.
