Abstract

The paper presents the investigations of the mechanical properties water absorption and porosity of the roller compacted concrete pavements (RCCP) with different amounts of nano-CaCO3. The nano-particles of CaCO3 were partially added to RCCP, and the mechanical properties of the specimens were measured. The results indicate that nano-CaCO3 can improve the compressive strength and the tensile splitting strength of RCCP. The nano-CaCO3 used up to 1% as a partial replacement for cement can accelerate the C-S-H gel formation at the early ages of hydration. This is due to increased crystalline Ca(OH)2 amount during the early ages of hydration. Increasing nano-CaCO3 content by more than 1% decreases the compressive and tensile splitting strength, and increases water absorption and permeability. The addition of CaCO3 nano-particles may increase C-S-H content, which improves the mechanical properties of concrete, fills the concrete pores, and decreases water absorption and permeable voids volume.
