- Abstract
- Bridging the gap among various phases is an effective approach to modify the overall performance of concrete. This paper presents a systematical investigation via multi scale methods, including macro performance, meso ITZ features and quantitative microstructure determination, to evaluate the effect of limestone powder (LP) and slag on the homogeneity of concrete. Although substituting 10% of LP, or 70% of slag for Portland cement could reduce the compressive strength, the differences among pastes, mortars and concretes are reduced remarkably. The addition of LP and slag is able to promote the hydration of cement and homogenize the mineralogical compositions. Using LP and slag for preparing binary or ternary binder would refine the pore structure especially in the region close to aggregate via micro filling, nucleation sites and latent hydration. It is expected to enhance the understanding of behavior modification of blended cement concrete from the perspective of multi-scale homogeneity.
