“…It has been used in combination with fly ash of coal combustion as a partial substitute of Portland cement, showing several advantages in terms of mechanical performance and durability (Thomas and Bamforth, 1999;Barbhuiya et al, 2009;Nochaiya et al, 2010;Lilkov et al, 2014). Silica fume of sub-micro size is an active component which will react with Ca(OH) 2 to produce the C-S-H (gel) phase.…”

“…Depending on particle size, silica content, and the degree of crystallinity, these wastes can be used as cements, pozzolanic admixture, or filler [3][4][5]. 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.

“…12, 13 Cakır and Sofyanlı 14 observed continuous and significant improvements in the compressive and splitting tensile strength of recycled aggregate concretes due to the incorporation of SF. Moreover, its durability properties such as sulfate resistance, chloride iron impermeability, and freeze-thaw resistance could also be enhanced.…”

Experimental investigations on the influence of different amounts of polyacrylic ester and silica fumes on the mechanical properties of mortar such as the compressive strength, splitting tensile strength, bonding strength, and abrasion resistance are presented in this article. The results show that the compressive and splitting tensile strength of mortar can be improved with the addition of polyacrylic ester and silica fumes. Results obtained from both the direct tensile bond test and flexural bond test indicate that the addition of polyacrylic ester and silica fumes improves the bond strength significantly, and the enhancement is more obvious with polyacrylic ester paste as interfacial adhesives. Furthermore, mortar incorporation of polyacrylic ester and silica fumes shows superior abrasion resistance compared to the control mortar. Therefore, the correct combination of polyacrylic ester and silica fumes to produce mortars has been shown to have synergistic effects, which results in excellent properties including high bond strength and superior abrasion resistance. Mortars containing polyacrylic ester and silica fumes are ideal for repairing concrete especially for hydraulic concrete structure.
