“…In recent years, SF has been widely used in concrete production, mainly because SF can not only improve the particle size distribution of cement‐based materials and enhance the compactness of matrix [ 30 ] but also improve the mechanical properties of concrete. [ 31–33 ] A few attempts have been made to investigate the effect of silica fume on the properties of cement‐based materials. Wang et al [ 34 ] reported that the introduction of 8–12 wt% SF into low‐heat Portland (LHP) cement accelerated the hydration of LHP cement, effectively improved the early strength of LHP cement, and significantly refined the pore structure of LHP cement.…”

Herein, the properties of concrete containing graphene oxide (GO) and silica fume (SF) are systematically investigated. The results show that the excellent properties of GO and SF have a significant improvement effect on the performance of concrete. Among them, the compressive, splitting tensile, and flexural strength of B‐1 group (GO, 0.01 wt% and SF, 2.5 wt%) are increased by 11.04%, 12.23%, 20.11% compared with the reference group after 3 days of curing. Meanwhile, the water penetration height of B‐1 group is decreased by 59.67% compared with reference group. The mass loss and relative dynamic modulus loss are 5.32% and 8.89% after 75 freeze‐thaw cycles, which are much lower than the reference group. Moreover, the micromodification mechanism of GO and SF on the concrete is investigated by using X‐ray diffraction analysis, scanning electron microscopy, and mercury intrusion porosimetry. The results show that the incorporation of GO and SF promotes the early hydration reaction of cement, improves the internal structure of the matrix, and enhances the compactness of the matrix.

“…The replacement of cementitious materials may reduce the production of cement and the emission of greenhouse gases into the atmosphere [4]. Silica fume is a type of admixture that is commonly used as a cement replacement material and it is produced from the waste of ferrosilicon alloys [5]. It is a pozzolanic material that combines with Ca (OH)2 and creates C-S-H, it avoids the voids or pores between concrete and enhances the strength and durability due to proper packing [5,6].…”

In the present era, concrete is one of the most commonly used construction materials worldwide. Consequently, the demand for natural river sand is increasing. Since the mining of natural sand has already been outlawed by the government in many regions, now it is essential to look into sustainable materials to control natural sand extraction. Hence, manufactured sand (MS) has been shown in numerous studies to be a more practical and environmentally responsible alternative to river sand (RS), which is normally used in the production of concrete. At the same time, the cement industry produces tons of greenhouse gases into the atmosphere, affecting atmospheric conditions. Now, it’s time to look into a suitable replacement material for cement. To investigate the feasibility of using manufactured sand & silica fume in place of river sand and cement under normal climatic conditions fresh, mechanical and durability properties were conducted in the laboratory. Twelve samples of M30 grade cubes and cylinders at desired M sand percentages of 0, 20, 40, 60, 80, and 100 & 0% and 5% variation of silica fume with cement are included in this study as a comparison to the control mix. After 28 days of water curing, a random variation in the properties of concrete was observed in the samples. In this experimental study, SF represents Silica Fume, MS represents manufactured sand, RS represents river sand, FA represents Fine aggregates and CA represents Coarse aggregates.

“…The main objective is to move forward strength of concrete by utilizing pozzolanic materials such as silica rage, metakaolin, GGBS as partial substitution to weight of cement by changing percentages (5, 10, and 15), and M-Sand as complete substitution to river sand. In this article, the test work is primarily concentrated on analyzing the mechanical strength, split tensile strength conjointly nondestructive tests like rebound hammer, and ultrasonic pulse velocity tests was performed at an age of 7 days and 28 days [13].…”

The river sand is a primary parameter in the concrete structure. This work replaces accessible locally accessible substitution materials like red soil and manufactured sand (M-Sand). In this paper, the mechanical properties and durability of concrete containing red soil and M-Sand have been studied. In this investigation, M30 grade concrete was used, and tests were conducted for two sets of combinations; i.e., red soil as a partial replacement for river sand seems to be 20%, 30%, 40%, 50%, and 60%, and red soil as a partial replacement for manufactured sand (M-Sand) seems to be 60%, 50%, 40%, 30%, and 20%. The compressive strength (7 days, 28 days, 90 days), split tensile strength (28 days), and flexural strength (28 days) have been determined. The combination S4-50% river sand + 50 % red soil and S9-70% M- Sand + 30 % red soil gives more compressive strength than other combinations. Similarly, the combination S3-60% river sand + 40 % red soil and S6-40% M- Sand + 60 % red soil gives more flexural and split tensile strength than other combinations. The scanning electron microscope (SEM) analysis, EDAX analysis, and durability tests like alkalinity, sulfate attack, and chloride attack have also been studied.
