To test whether or not the addition of biochar like unreactive filler to concrete could enhance its efficiency properties and provide a chance for carbon sequestration, researchers swapped out the sand and also coarse aggregate typically used in concrete with biochar. A linear relationship between bio...
2. Hence, self-sensing concrete can be regarded as a three-phase composite material, including concrete matrix phase, functional filler phase, and the interface phase between them, among which the functional filler phase and interface phase dominate the conductive and sensing properties of self-...
Thus, the optimum wt% of nanofiller can deter crack growth between the fibre and matrix, resulting in efficient energy absorption, while lower filler wt% cannot effectively mitigate the impact energy between the fibre and matrix. In the case of higher nanofiller content, agglomerates of nano...

Figure 20 presents the experimental devices for laser welding which utilize the filler wire provided in front of the laser’s moving direction of travel, and the Nd:YAG laser has a maximum output of 4.4 kW. As shown in figure 20, the laser is tilted approximately 18º from the vertical ...
[8]. In the NSM strengthening technique, slits were formed in the concrete cover, and the reinforcement was embedded into it with groove filler (epoxy or cement mortar). The NSM efficiency made it an effective technique to upgrade the RC elements [9]. In the first appearance of the NSM ...

Furthermore, fine CBA particles also behaved as a filler for pores in the concrete, reducing the overall porosity and capillary pore and producing a denser microstructure [4]. Beyond the optimum replacement rate, water absorption starts to increase, which might be due to the porous structure of...
Additionally, recycled concrete is a common filler used in the manufacturing of cellular concrete. It has no substantial influence on the compressive strength of recovered concrete [12]. It has also been shown that different percentages of burned ceramic wastes may be used in lieu of aggregates ...
