“…It is noteworthy, however, that while FC is widely accepted, it does have some downsides, such as high permeability, high shrinkage, brittleness, and a higher probability of cracking because of its permeable structure, primarily associated with voids, which restrict its application to building construction in terms of load-bearing requirements [ 23 , 24 ]. FC has been found to be volatile in many studies, especially when its density declines [ 25 ]. Even small variations in the FC density can have a substantial influence on the FC's durability and performance.…”

“…The absence of a viable substitute material in the foreseeable future further emphasizes the importance of studying the behavior of concrete in both its fresh and hardened states. Having a comprehensive understanding of concrete properties is also crucial for developing effective strategies to enhance its performance and lifespan in various applications [6][7][8][9][10]. The use of concrete as a construction material has been increasing year by year.…”

The intent of this study is to explore the physical properties and long-term performance of concrete made with metakaolin (MK) as a binder, using microsilica (MS) and nanosilica (NS) as substitutes for a portion of the ordinary Portland cement (OPC) content. The dosage of MS was varied from 5% to 15% for OPC-MK-MS blends, and the dosage of NS was varied from 0.5% to 1.5% for OPC-MK-NS blends. Incorporation of these pozzolans accelerated the hardening process and reduced the flowability, consistency, and setting time of the cement paste. In addition, it produced a denser matrix, improving the strength of the concrete matrix, as confirmed by scanning electron microscopy and X-ray diffraction analysis. The use of MS enhanced the strength by 10.37%, and the utilization of NS increased the strength by 11.48% at 28 days. It also reduced the penetrability of the matrix with a maximum reduction in the water absorption (35.82%) and improved the resistance to the sulfate attack for specimens containing 1% NS in the presence of 10% MK. Based on these results, NS in the presence of MK can be used to obtain cementitious structures with the enhanced strength and durability.

“…LFC stands out from other highly air-entrained materials because it has a volumetric air content that is greater than 25 percent. The use of LFC in the context of the Malaysian construction industry is still in its infancy [25], despite the increased attention that it has received on a global scale. On the other hand, it has been implemented in a number of construction and void-filling projects.…”

The utilization of natural fibres for the invention of building materials has increased significantly in recent years in the construction industry. Hemp fibre-reinforced concrete, according to research, can provide low-cost building materials for residential and low-rise buildings while achieving sustainable construction and meeting future environmental targets. The purpose of this research was to improve the durability of lightweight foamed concrete (LFC) reinforced with hemp fibre (HF). Six weight fractions of HF were considered specifically 0.0% (control), 0.1%, 0.2%, 0.3%, 0.4% and 0.5%. Besides, three densities of LFC which were 500, 900 and 1300 kg/m3 were cast and tested. The properties evaluated were drying shrinkage, water absorption, depth of carbonation and porosity. From the durability tests, it was observed that the optimal results for water absorption, depth of carbonation and porosity tests were attained with the addition of 0.5% HF into LFC mixes. For the drying shrinkage test, LFC with the weight fractions of 0.3% (500 kg/m3), 0.4% (900 kg/m3) and 0.5% (1300 kg/m3) reveal the optimal drying shrinkage. This research has provided a foundation for further research into HF-strengthening LFC. There is a huge potential to utilize HF in cement-based materials for durability and mechanical properties enhancement. The use of industrial HF might make it possible to reduce fine aggregate while still producing LFC of higher quality. The inclusion of agricultural fibres in LFC will also promote the expansion of farming operations, which will have rewarding economic benefits.
