Mechanical properties of structural concrete with fine recycled ceramic aggregates

Influence of the water variation on the mechanical properties of concrete manufactured with recycled mixed aggregates for pre-stressed components

“…A significant decrease occurred when 100% of natural aggregates were replaced by RMA. This agrees with the consulted literature [15,[21][22][23]. This is due to the lower elastic modulus of each of the components used to elaborate the concrete.…”

Mechanical performance of concrete made with aggregates from construction and demolition waste recycling plants

“…They justified this trend with the better bond between the ceramic aggregates and the cement paste, because of the greater porosity of the RA. Alves et al (2014) found an increase in abrasion resistance of 31.4% and 49.8% from the use of 100% of coarse ceramic RA from bricks and sanitary ware.…”

“…Other studies also hint at an increase of compressive strength when 30% of NA are replaced by ceramic RA (http://www.sciencedirect.com/science/article/pii/S0959652612004660 Pacheco-Torgal and Jalali, 2010). Alves et al (2014) analysed the incorporation in concrete of coarse ceramic RA from bricks and sanitary ware. They found that the decrease of 28-day compressive strength is less than 10% for full replacement of NA with coarse brick RA.…”

Suitability of mortars produced using laterite and ceramic wastes: Mechanical and microscale analysis

“…Currently, there are quite a number of interesting studies regarding the use of laterite [21,[23][24][25] and ceramics [16,18] as replacement for natural aggregates. However, there are no many studies [21], which have considered using both laterite and kaolin-rich material such as ceramic or marble products in mortar and concrete.…”

“…Studies such as [12,[16][17][18] have explored the suitability of sanitary wares, white and red ceramic as aggregates in mortar and concrete. Thus, it has been established that these ceramic products could replace natural aggregates in concrete, due to the observed strength performance of such concretes.…”
