“…To begin with, silica nanoparticles with nanoscale in size act as a filler, filling the pore spaces within the cement structure, and hence, densify the cement structure and compact it, in addition to its ability to reduce the capillary porosity. Second, the high silica content (>99%) enables nanosilica to have a stronger pozzolanic activity that gives its accelerators functionality. , …”

“…Second, the high silica content (>99%) enables nanosilica to have a stronger pozzolanic activity that gives its accelerators functionality. 29,30 The influence of nanosilica on cement hydration was investigated by Silvestre; 31 according to his findings, mixing nanosilica into cement grains produces H 2 SiO 4 , which interacts with the present Ca 2+ to generate more calcium silicate hydrates (C−S−H), as illustrated in Figure 5. These C−S−H gels spread into the water between the cement particles, acting as seeds for a more compacted C−S−H phase to form.…”

The oil well cementing job is the operation in which a cement paste is pumped to fill the annulus behind the casing. Inclusion of nanomaterials in oil well cement results in improving the cement properties. This paper provides a comprehensive overview of incorporating nanosilica into oil well cement, addressing various aspects of the nanosilica manufacturing process, dispersion challenges, the impact on cement hydration and properties, as well as the operational challenges. The addition of nanosilica is found to enhance cement properties such as hydration rate, compressive strength at low temperatures, and resistance to deterioration at high temperatures. However, challenges arise, including increased viscosity and the need for higher water content. Dispersion of nanosilica into cement slurry remains a difficulty, compounded by the high manufacturing cost, limiting its practical application. The paper recommends further research to improve nanosilica dispersion, explore cost-effective raw materials, and overcome operational challenges for broader utilization in oil well cementing.

“…To improve the functionality of concrete, the amount of research related to the reinforcement of concrete structures has increased [10,11]. Several studies carried out in the areas of nanotechnology have shown that the addition of nanoparticles to cement induce some significant changes in the microstructure [12], resulting in less porous [13] and more durable concrete [13,14].…”

Concrete is a leader composite material for structural use in buildings, adaptable to all locations and circumstances in view of its properties such as versatility, durability, and performance. MXenes are new two-dimensional (2D) materials that are very promising for applications in many fields due to their layered structure and physicochemical characteristics. Focused on increasing the performance of concrete structures, this work proposed the reinforcement of concrete with the addition of very small amounts (0.02 wt.-%) of MXenes consisting of multi-layer Ti3C2Tx nanosheets to improve compression and abrasion resistance. The reinforced concrete specimens were tested by uniaxial compression tests and rubber-wheel abrasion tests. The results obtained were compared with reference concrete prepared without any added nanosheets. The concrete with MXenes presented higher compression strength (15% higher) in relation to the reference samples after 3 days of molding. After 28 days, the average compression strength was 20.5% higher with Mxenes, but the difference at 28 days was not statistically significant. The rubber-wheel abrasion tests showed a tendency for reduced wear rates with Mxenes, but the difference was statistically significant only for the tests with larger abrasives. Differences in macroporosity of the concretes were not found to justify the improved performance with Mxenes. The main differences due to the Mxenes reinforcement were due a smoother microtopography. It was proposed that the mechanism responsible for obtaining smoother topography with MXenes was related to the lubricious nature of the Ti3C2Tx nanosheets, that can reduce interparticle friction when a transition of the paste flow to the thickening regime occurs, which is governed by boundary lubrication.

“…In addition, the manufacturing industry is facing many problems, including the availability of natural raw materials and the increase in energy consumption and other expenses. High energy consumption has led to an increase in the emission of carbon dioxide into the atmosphere, which is associated with climate change [18]. Therefore, a reduction in the use of natural resources, together with the reuse and recycling of materials, may help to alleviate this problem.…”

The transformation of conventional binder and grout into high-performance nanocarbon binder and grout was evaluated in this investigation. The high-performance nanocarbon grout consisted of grey cement, white cement, lime, gypsum, sand, water, and graphite nanoplatelet (GNP), while conventional mortar is prepared with water, binder, and fine aggregate. The investigated properties included unconfined compressive strength (UCS), bending strength, ultrasound pulse analysis (UPA), and Schmidt surface hardness. The results indicated that the inclusion of nanocarbon led to an increase in the initial and long-term strengths by 14% and 23%, respectively. The same trend was observed in the nanocarbon binder mortars with white cement, lime, and gypsum in terms of the UCS, bending strength, UPA, and Schmidt surface hardness. The incorporation of nanocarbon into ordinary cement produced a high-performance nanocarbon binder mortar, which increased the strength to 42.5 N, in comparison to the 32.5 N of the ordinary cement, at 28 days.
