Durability of Cementitious Composites Mixed with Various Portland Limestone Cement-Cements
This paper presents a durability study of cementitious composites mixed with seven Tunisian blended cements (portland limestone cement-cement [PLC-cement]) manufactured on an industrial scale with a varying limestone filler content (up to 35%). The durability tests were performed on mortars and concretes according to existing standards. The results show that limestone filler has different effects on the durability of composites, depending on the limestone amounts and the grinding quality of binders. Thus, they improve concrete resistance to the leaching of calcium ions into mono-distilled water, particularly when they are finer (more 99% of limestone < 40 µm). Furthermore, limestone does not alter the resistance to the sulfate ion attack when its content does not exceed 25%. However, freezing and thawing causes rapid deterioration (decrease) in mechanical properties if the limestone content is higher than 25%. These results can serve as a recommendation for using PLC-cements in countries where they are rarely used.
