Abstract:
The influence of mix constituents on the quality of concrete is discussed. Results demonstrate that the assessment of concrete performance based on the traditional parameters such as water-cement ratio and 28-day strength may be misleading. One way to insure a durable structure is to specify concrete by performance criteria. This would overcome not only the influence of constituents, but would also place emphasis on proper curing. For the protection of reinforcement against corrosion, performance criteria based on carbonation and water sorptivity are suggested.
