摘要: In freshly compacted concrete, water films form around aggregate particles, which results in a higher water/cement ratio closer to the than away from it. The interface between cement paste and aggregate, known as interfacial transition zone (ITZ), has significantly porosity bulk paste. This ITZ affects transport properties of concrete. Wood's metal technique was used intrude molten alloy into voids fractures concrete then solidified preserve microstructure. penetration this samples indicates that is permeated preferentially also width interconnected. experimental study were evaluated probabilistic sense subject statistical considerations. particular, interpretations properly account for aleatory epistemic uncertainties inherent data.
