“…The most common wastes used in blended cements are blastfurnace slag, fly ash, silica fume, rice husk ash, and sugarcane bagasse ash [6][7][8][9][10]. Published results report that the use of glass particles for the partial replacement of aggregates or cement can result in beneficial or deleterious effects on the performance of cementitious compounds materials [11][12][13][14][15][16][17].…”

Different studies investigate the use of waste glass in Portland cement compounds, either as aggregates or as supplementary cementitious materials. Nevertheless, it seems that there is no consensus about the influence of particle color and size on the behavior of the compounds. This study addresses the influence of cement replacement by 10 and 20% of the colorless and amber soda-lime glass particles sized around 9.5 m on the performance of Portland cement mortars. Results revealed that the partial replacement of cement could contribute to the production of durable mortars in relation to the inhibition of the alkali-aggregate reaction. This effect was more marked with 20% replacement using amber glass. Samples containing glass microparticles were more resistant to corrosion, in particular those made of colorless glass. The use of colorless and amber glass microparticles promoted a reduction in wear resistance.

“…The flexural strength of the mortar with the starting materials was approximately 11% to 14% lower than that of the mortar with the original fine aggregate. Similarly, when recycled coarse aggregate was used, the flexural strength of the concrete was approximately 27% lower than that of the concrete with ordinary aggregate (Nassar et al 2012). Moreover, when both coarse and fine recycled aggregates were used, the compressive strength of the concrete was approximately 20% lower than that of the concrete with the commonly used aggregate (Hansen 1986).…”

Crushed recycled aggregate contains particles with brittle defects such as cracks, pores, and voids. This study presents a method for improving the quality of recycled fine aggregate by selectively removing these defects. Fourteen recycled fine aggregates were manufactured by three types of processors including a jaw crusher, ball mill, and granulator. The influence of the recycled fine aggregate on the flowability and strength of the mortar was evaluated by multivariate analysis. The results showed that flowability was mainly affected by the filling fraction of the recycled fine aggregate and the content of components passing through a 0.075-mm sieve. Both the compressive and flexural strengths of the recycled mortars were unaffected by the filling fraction, but they were affected by the fraction of defects in the aggregate and its surface smoothness. In addition, the results clearly showed that polishing involved in ball mill or granulator processing is effective both for increasing the filling fraction of recycled fine aggregate and reducing the fraction of defects in the aggregate. Moreover, it was determined that the grain surface of grains was more irregular with the granulator than that with the ball mill, resulting in higher strength of the mortar subjected to the granulator. The fracture configuration resulting from flexural stress on the recycled fine aggregate in the mortar differed according to the type of aggregate. Furthermore, the calculated amounts of emitted CO 2 and the compressive strength of the recycled mortar showed that the recycled fine aggregate should not be polished excessively.

“…The volume of the residual mortar in RA varies from 25% to 60% according to the size of aggregate [5]. Some researchers have reported in their studies that around 20% of cement paste is found attached to the surface of RA for particle size range from 20 to 30 mm [6,7]. What is specific for RCA is a presence of several types of interfacial transition zone (ITZ) -between the ''old'' and ''new'' compounds, that may play a key role in the internal microstructure of a concrete ( Figure 1).…”
