Durability of similar self-compacting concrete batches produced in two different EU laboratories
چکیده انگلیسی

The present study intends to evaluate the sensitivity of self-compacting concrete (SCC) mixtures, cast in two different laboratories of the European Union, with a focus on rheological parameters, mechanical characteristics and durability properties. Six SCC mixtures with different water-to-binder ratios and silica fume levels of cement replacement and two normally vibrated concrete (NVC) mixtures have been compared. It has been found that the reproducibility of similar mixtures is possible, when using different constituent materials that conform to the European Standards. Comparable rheological, mechanical and durability properties can be achieved. Open porosity and sorptivity appear to be more sensitive than chloride penetrability.


► Reproducibility of similar mixtures is possible between different laboratories.
► Open porosity and sorptivity appear to be slightly sensitive to local materials.
► Different local materials appear to have a low impact on chloride penetrability.
► Water-to-binder ratio correlates well with all mechanical and durability properties.
► Higher silica fume percentages improve all mechanical and durability properties.
