“…The results show that the compressive strength of all the specimens increased with the increase of the curing time. With the increase in dosage, the 3 d strength first increased and then decreased, and the test results were consistent with those of other scholars [11,24,25]. The 28 d strength P + M1 and P + M3 gradually decreased, while the variation law of P + M2 and the 3 d strength was similar, different from that in Reference [11].…”

The resource utilization of waste stone powder is a meaningful way to realize sustainable development. This paper aims to study the influence of marble waste powder particle size and replacement cement dosage on the mechanical properties of cementitious materials and evaluate its microstructure and mineral characterization by SEM and XRD. The results show that the early strength of cementitious materials is obviously improved when the dosage of marble waste powder is in the range of 0–15%, and the lifting effect of marble waste powder with a particle size of 600 mesh instead of cement on the strength and microstructure of cementitious materials is the most obvious. The replacement of cement with different particle sizes of marble waste powder found that it had low chemical activity and participated in the hydration reaction of cement, but the reaction degree was low. The smaller the particle size of marble waste powder instead of cement, the denser the early microstructure, the more obvious the nucleation phenomenon, and the more serious the agglomeration between particles. In addition, the mechanism model of marble waste powder replacing cement cementitious materials was proposed. The strength prediction function model between the material dosage and compressive strength was constructed, and the accuracy of the model was verified.

“…To reduce these problems, RHA could be used as cement substituted materials because it contains an enormous amount of amorphous silica, which has pozzolanic action and possesses cementitious property. In addition, the agricultural byproduct RHA has already been substantiated as a pozzolanic material [11][12][13]. It is expected to add pozzolanic values in cement hydration, which, in turn, enhances strength and durability over a longer period [14,15].…”

“…Furthermore, Sakr [32] found that the compressive strength of control concrete was much lower than concrete containing 15% of RHA when immersed in a sulfate solution for 28 days. Countless efforts have been made to explore the strength and durability properties of concrete containing RHA in stone aggregate concrete [13,15,[32][33][34][35]. However, crushed brick as a coarse aggregate including RHA may be an alternative option.…”

This study assessed the strength and durability parameters of brick aggregate concrete (BAC) incorporating rice husk ash (RHA) as a partial replacement of cement. For this, concrete cylinders (100 mm × 200 mm) were made with 0% (control) to 25% RHA as a partial replacement of ordinary Portland cement (OPC) at a mix proportion of 1 : 1.5 : 3 and a water-to-binder (w/b) ratio of 0.50. Specimens were immersed separately in normal water, 3% sodium chloride (NaCl), 5% sodium sulfate (Na2SO4), 5% magnesium sulfate (MgSO4), 1% hydrochloric acid (HCl), and 1% sulfuric acid (H2SO4) solutions for several immersion periods. The slump test results indicated that the workability of BAC containing RHA (RBAC) decreased about 29.69%–75.02% compared to control (0% RHA). After 90 days, the BAC containing RHA (up to 15% replacement) was found approximately 2.28%–6.64% greater compressive strength than that of control concrete. In addition, water absorption and porosity of RBAC were around 17.59%–40.73% and 12.12%–35.68% lower than that of control concrete, respectively. Similarly, RBAC (up to 25% replacement) exhibited roughly 35.62%–54.79% higher resistance against chloride attack and 0.39%–4.56% better resistance against Na2SO4 attack (up to 15% replacement), however, it exhibited inferior resistance against MgSO4 attack compared to control. Meanwhile, BAC with 10% RHA showed about 5.35% and 1.00% superior performance than that of control concrete against HCl and H2SO4 attack, respectively. The relationships between the strength and durability parameters of RBAC also suggested that RHA contributes to improving the strength and durability parameters of BAC.

“…Nano-silica (NS) improves the cementitious material hydration and increases their pozzolanic activity [8]. The durability and environmental resistance of normal concrete (NC), geopolymer concrete, and high-strength concrete (HSC) were improved by adding NS or rice husk ash (RHA) and marble dust [9][10][11][12]. In addition, as SF and NS were incorporated in concrete, the concrete sulfate and chloride resistance was enhanced more than adding SF or NS separately [12].…”

In this study, the strength reduction of high-strength concrete (HSC) integrating silica fume (SF) and nano-silica (NS) exposed to elevated temperatures besides its mass loss is evaluated. Cubes and cylinders were cast and tested at 28 and 56 d to evaluate the concrete compressive and tensile strengths (f cu and f tu ), respectively. The prepared cubes and cylinders were subjected to elevated temperatures (T = 200, 400, 600, 800, and 1000 °C), cooled in air, and tested in compression and tension, respectively. For the cement paste and aggregate, spot analysis was performed through scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS). Furthermore, SEM between aggregate and cement paste was performed. The obtained results indicated that for concrete mixes incorporating NS, compressive strength increased as temperature was raised to 400 °C and decreased as temperature increased from 400 to 800 °C. In addition, a remarkable reduction in the concrete tensile strength was observed up to T = 800 °C. At T = 1000 °C, all specimens were destroyed. Moreover, the lowest Ca/Si ratio was observed for the NS mixes according to the EDS spot analysis results. The mass loss of the concrete mixes integrating SF was higher than that of the mixes integrating both SF and NS except at 800 °C. Finally, a detailed review of the effect of macro and nanomaterials on the concrete properties was presented.
