SummaryDescribe the proposed research in about 200 words.The main aim of this project will be to investigate the early age strength development of ground granulated blast furnace slag (ggbs) and also ternary, i.e. ggbs with condensed silica fume (microsilica) (csf), composite cement concretes under simulated in-situ temperature histories in order to give guidance for their use in fast track construction. The use of ggbs and ternary systems with csf in concrete although economic has not gained popularity in fast track construction because of the slower strength gain of these mixes at standard curing temperatures. There are however indications that ggbs is heavily penalised by the standard curing regimes. The high early age temperatures occurring inside structural elements appear to provide the activation energy needed for the pozzolanic reaction to kick-in earlier. This results in in-situ/standard cured strength ratios of 2.0 to 2.4 as compared to ratios of 1.0 to 1.4 for ordinary Portland cement concrete mixes. State-of-the-art computer modelling techniques and software will be used. It is important that techniques for monitoring the strength development on site, e.g., pull-out tests and maturity measurements, are validated for these composite cements.
