Effect of metakaolin on early strength of GGBS ternary concrete


Mohd. Nasir, Noor Azline and McCarthy, M. J. (2014) Effect of metakaolin on early strength of GGBS ternary concrete. Applied Mechanics and Materials, 584-586. pp. 1551-1557. ISSN 1660-9336; ESSN: 1662-7482


The article reports a laboratory experimental programme that investigated effect of metakaolin on the early strength of concrete made with ternary combinations of Portland cement (CEM I) with ground granulated blast slag (GGBS) and metakaolin (MK). The various level of cement combinations (65%CEM I+30%GGBS+5%MK, 45%CEM I+45%GGBS+10%MK and 45%CEM I+40%GGBS+15%MK) was examined in comparison to CEM I and equivalent GGBS binary concretes for up to 28 days. Results show that the reduction in early strength is greater with the higher cement replacement level. However, the ternary concrete containing 15%MK has minor increase in early strength compared to those with 10%MK but a significant increase in strength is examined at later age (28 days). It is concluded that the presence of MK compensates the adverse effect of GGBS at early strength development and improves the strength at later ages.
