The author stresses the need for site supervision in the production and use of concrete so that the material will possess good surface appearance, durability and strength. Options open for the supply of concrete, including ready-mixed concrete, with their advantages and disadvantages are tabulated. The effects of variations in aggregate properties, cement, mixing water, admixtures, and mix proportions on concrete quality are presented and tabulated, with a discussion of the effects of materials handling and segregation on aggregate grading. The author presents information on mix design for concrete of various grades, with volume or mass batching of materials. Guidance is given on the use of strength tests for monitoring concrete quality. Concrete supply is then considered in more detail, with mix design procedure according to the New Zealand code of practice. Instructions are included for the monitoring of concrete production.
