“…Onuaguluchi [ 15 ] significantly improved the wear resistance of rubberized cement mortar by replacing 10% of the volume with SF. However, the enhancement of concrete or mortar wear resistance with SF is based on relatively high blending ratios (≥10%), and an excessive proportion of SF in the cementitious material system can lead to severe shrinkage issues [ 16 , 17 , 18 ], adversely affecting the road performance of concrete.…”

To solve the problem of the poor abrasion resistance of concrete pavement surface mortar, this study substituted cement with equal amounts of styrene–butadiene rubber (SBR) latex and silica fume (SF) to investigate the effects of organic/inorganic material composite modification on the fluidity, drying shrinkage, mechanical properties, and abrasion resistance of cement mortar. Also in this study, the microstructure, product, and pore structure characteristics of the composite modified cement mortar were investigated using scanning electron microscope (SEM), X-Ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), and the Brunauer–Emmett–Teller (BET) method. This research found that the sole substitution of SF negatively impacted the mortar’s fluidity and drying shrinkage yet enhanced its mechanical strength and abrasion resistance; the incorporation of SBR latex improved fluidity, reduced shrinkage, and increased flexural strength but adversely affected the compressive strength of the mortar. Additionally, the enhancement of the mortar’s abrasion resistance with SBR latex was significantly greater than that with SF. When SBR latex and SF were used together as substitutes, the latex struggled to offset the negative impact of SF on mortar fluidity but effectively reduced shrinkage; SF compensated for the detrimental effect of the latex on compressive strength. Moreover, the primary role in enhancing the mortar’s abrasion resistance was played by the latex. Microscopic tests showed that SBR latex and SF could increase the content of calcium silicate hydrate (C-S-H) gel, inhibit the formation of ettringite (AFt) and reduce carbonation, refine the pore size of cement mortar, and effectively improve the microstructure of mortar.

“…Silica additives also improve the durability of concrete by reducing its porosity [ 11 , 13 , [15] , [16] , [17] , [18] , [19] ]. Research was performed by using pure nano-silica in concrete and it was found that using Nano-silica in concrete can enhance the compressive strength and decrease the apparent chloride diffusion of the concrete [ 16 ].…”

“…Research was performed by using pure nano-silica in concrete and it was found that using Nano-silica in concrete can enhance the compressive strength and decrease the apparent chloride diffusion of the concrete [ 16 ]. Furthermore, silica additives also have been known to improve the resistance of concrete to chemical attack [ 19 , 20 ]. Research related to durability was conducted by combining fly ash and silica fume to investigate its effect on the freezing-thawing and sulfate attack resistance.…”

“…Due to the high amount of availability Sugar cane bagasse and its cost efficiency, it is utilized as a fuel in sugar mills [12] . Due to the silica content, it shows good cementitious properties, this property made it a sustainable material [13], [14]. Silica fume, commonly referred to as condensed or micro silica is used as an artificial pozzolanic additive [15] .…”

Cement industries are producing high amounts of carbon dioxide, this problem leads to supplementary cementitious materials utilization. Utilization of agricultural and industrial waste in concrete reduces pollution and disposal problems. This work presents the performance evaluation of the ternary blended concrete mixes in which Silica fume and Sugarcane bagasse ash are used as mineral admixtures. A total of six mixes is used including the Reference mix, which is denoted by M0, M11, M12, M13, M14, and M15 whereas M0 represents the reference mix. M11, M12, M13, M14, and M15 are prepared by partially replacing the cement with SCBA by 5%, 10%, 15%, 20%, and 25% respectively. All the mixes were tested against mechanical and workability properties along with durability Properties and the results are clear that the mix with 15% SCBA and 5% Silica Fume significantly got better results.
