Flexural strength is usually improved by the use of slag cement, which makes it beneficial to concrete paving applications where flexural strengths are important. It is believed that the increased flexural strength is the result of the stronger bonds in the cement-slag-aggregate system because of the shape and surface texture of the slag particles.
