“…Additionally, KSiO 2 has less viscosity than Na 2 SiO 3 [47]. Potassium alkali agent decreased viscosity results in greater strength and durability with less shrinkage and porosity [50,51]. When compared the curing condition of GPC with ambient and oven-cured conditions, it was concluded that the oven curing condition shows a higher CS value than the ambient condition [48].…”

“…A measured amount of epoxy is taken and preheated to reduce its viscosity before ultrasonication. [18,19] Filler materials were added to ethanol solvent and sonicated for 10 min. The filler materials were then added to epoxy and initially mixed manually for about 5 min, which was then followed by sonication for about 50 min.…”

This work investigated the influence of carbon nanofibers (CNFs) and aggregate of CNFs with micro‐sized short carbon fibers (SCFs) on the mechanical, thermal, and fracture properties of epoxy (80%) ‐ Polylactic acid (PLA) (20%) composite. Epoxy‐PLA composite loaded with CNFs (0.2, 0.3, and 0.4 wt.%) and a combination of CNFs and SCFs (0.2 and 0.4 wt.% with equal content of each filler) were manufactured by sonication and manual casting. The synergistic effects of CNFs and SCFs in the epoxy matrix were investigated through mechanical and fracture characterization of nanocomposites. In comparison to CNF‐reinforced nanocomposites, the composites reinforced with integrated multiscale fillers have higher tensile, flexural, impact strength, and fracture toughness. Tensile, flexural and impact strength increased by 17.18–25.72%, 39.24–44.07%, and 39.87–97.05% respectively with the incorporation of both CNFs and SCFs into epoxy‐PLA matrices. An improvement in fracture toughness in the range of 37.93–38.77% was observed in hybrid nanocomposites in comparison to pristine epoxy‐PLA composite. The synergetic mechanism of nano and micro fillers was studied by using the fracture surfaces from tensile tests using scanning electron microscopy. The numerical analysis was also carried out to simulate the effects of filler concentration on the tensile and bending strength of nanocomposites through representative volume element using an ANSYS workbench.

Geopolymer is the alternative to current construction material trends. In this paper, an attempt is made to produce a sustainable construction composite material using geopolymer. Ground granulated blast furnace slag (GGBS)-based geopolymer concrete was prepared and tested for different alkaline to binder ratios (A/B). The effect of various temperatures on compressive strength properties was assessed. The cubes were exposed to temperature ranging from 50 to 70 °C for a duration ranging from 2 to 10 h, and the compressive strength of the specimens was analyzed for destructive and non-destructive analysis and tested for 7, 28, and 90 days. The obtained compressive strength (CS) results were analyzed employing the probability plot (PP) curve, distribution overview curve (DOC), probability density function (PDF), Weibull, survival, and hazard function curve. Maximum compressive strength was achieved for the temperature of 70 °C and an A/B of 0.45 for destructive tests and non-destructive tests with 44.6 MPa and 43.56 MPa, respectively, on 90 days of testing. The survival and hazard function curves showed incremental distribution characteristics for 28 and 90 days of testing results with a probability factor ranging from 0.8 to 1.0.
