Abstract

The paper reports the results of the tests used to determine hydration kinetics, physical properties and microstructure of hydraulic road binders. Seven hydraulically bound mixes were produced by mixing Portland cement (CEM I 32.5R), hydrated lime, and cement by-pass dust (CBPD) in proportions established as per the experimental plan. Cement by-pass dust was found to have the greatest effect on the increased water demand, hydration heat and soundness of the binder paste. Minerals derived from the hydration of input components were identified in the composition of the binder phases. In CBPD rich binders sylvite and calcium chloro-aluminate hydrate were present. The test results show that when planning the use of normal setting hydraulic road binders containing CBPD in road construction, the water to binder ratio w/b must be taken into account to ensure proper consistency, soundness, and amount of hydration heat release.

Keywords
