The paper descriptionbes a study carried out to investigate the use of South African condensed silica fume as a Portland cement replacement material in structural concrete. Aspects dealt with in the paper are fresh properties, strength development and the development of a mix design method. Results indicated a Significant effect by condensed silica fume on all concrete properties. Concrete workability was found to reduce dramatically with increasing dosages of condensed silica fume. However, rates of workability decrease were found to be test-dependent.
