DSP with Rutile Substituting for Microsilica

Abstract

DSP is made from heavily superplasticized cement combined with microsilica and relatively small amounts of water. In this paper it is shown that substitution of fine-grained rutile for microsilica results in a workable DSP mix.

A comparison of the TGAs, XRDs, SEMs, mercury intrusion porosimetry, and compressive strengths between the two DSP preparations is reported. The results indicate that the DSP made with rutile has very similar properties to DSP made with microsilica.
