Alkali-aggregate expansion corrected with Portland-slag cement
To correct alkali aggregate expansion, 50 to 60% of slag should be used, which does not reduce strength, rather than lower percentages which can not be exceeded with pozzolans unless strength is sacrificed; much smaller expansions were obtained with slag blends than with straight portlands; in many cases, slag can be used advantageously to replace 50 to 60% of portland clinker.
