Abstract

The basic procedure for this mix design method is applicable to concrete for most purposes including pavements which are specified by compressive strength. The basic procedure is restricted to designing concrete mixes to meet workability, strength and durability requirements using Portland cements and natural aggregates, or coarse air-cooled slag. It has been found possible to add a new modification to allow the method to be applied to mixes incorporating pulverised-fuel ash (pfa) or using Portland pulverised-fuel ash cement. Guidance is given on the design of mixes incorporating ground granulated blastfurnace slag (ggbfs) or using Portland-blastfurnace cements. The general principles and basic concepts are given in the Introduction. After this the publication is divided into three parts. Part one gives the background information which is required to understand the mix design procedure. Part two describes the mix design process and contains all the basic information in the form of tables and graphs for the application of the method to most concretes designed for compressive strength. A standardised form has been developed for use with this method, and a number of worked examples is given. Part three deals with modifications to the mix design method to deal with air-entrained concrete, and for the design of mixes incorporating pfa or ggbfs.
