Use of microsilica in concrete construction

Reviews state-of-the-art silica fume concrete and discusses the influence silica fume has on the various properties of concrete and the effect on the bond between parent concrete and new concrete. The advantages of using microsilica can be considerable as it reduces thermal cracking caused by the heat of cement hydration and can improve durability to attack by sulphate and acidic waters. The advantages and applications are reviewed and a number of test core illustrations are included.
