The results presented in this study show that varying compositions of ultra-fine
materials can considerably and substantially influence the concrete properties. The
study also shows that compressive strength and slump flow can be optimised by
optimising the fine content in the ternary mixture. The optimum content of the
industrial by-products, DMS and UFA, is nearly 10 %, for both, by weight of the
total binder content which results in maximum particle packing to give a maximum
average compressive strength of 123 MPa and a slump flow of nearly
650 mm. DMS supports early strength gain and UFA supports post 28 days
strength gain due to the pozzolanic action. Prolonged mixing period was necessary
to get a homogenised mixture and to increase the workability of the mixtures
because of high binder content.
