Plant and animal fibers are getting recognition from researchers and academicians as a potential reinforcement for polymer composites due to their ecofriendly nature and sustainability. In the present study, the fabrication has been carried out on Jute and Vetiver fiber reinforced Epoxy composites using hand lay-up technique with a varying mass of the fibers in epoxy and matrix modifier graphite which has been fixed by weight. The mechanical (tensile, flexural and hardness test), and physical properties (water absorption [WA] and moisture content behavior) of developed composites are determined. The results obtained from performed test show that tensile strength of around 212.96 MPa was achieved for 6 wt% of Vetiver, the flexural strength of around 266.267 MPa, and the Rockwell hardness is 70.08. The WA is found maximum for Vetiver, and Jute fiber reinforced epoxy composite in the sample with 8% Vetiver and 22% of Jute fiber of composite. Scanning Electron Microscopy micrographs clearly show the incompatibility of Vetiver fiber with Epoxy matrix, easily understood with pull out of Vetiver fibers from the matrix. The continuous fiber was used which is equal to the length of the casting, therefore, even due to debonding, fracture of Vetiver fibers occurred more than pull-out.

“…The results show that from a typical ambient temperature of 29 °C to an elevated temperature up to 400 °C, the flexural strength of both concrete mixes rises first. This improvement in flexural strength might be attributed to the fact that following heating, the specimens are cooled via the annealing process, which allows part of the evaporated water to be reclaimed from ambient moisture [ 35 , 38 , 39 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 ]. When the temperature was raised from 600 °C to 1000 °C, the flexural strengths of both concrete mixes plummeted.…”

Concrete is a composite material that is commonly used in the construction industry. It will certainly be exposed to fires of varying intensities when used in buildings and industries. The major goal of this article was to look into the influence of mineral additions such as foundry sand and marble dust on the residual characteristics of concrete. To examine the behavior of residual characteristics of concrete after fire exposure, marble dust was substituted for cement and fine sand was substituted for foundry sand in varying amounts ranging from 0% to 20%. It aided in the better disposal of waste material so that it might be used as an addition. The purpose of the experiment was to see how increased temperatures affected residual properties of concrete, including flexural strength, compressive strength, tensile strength, static as well as dynamic elastic modulus, water absorption, mass loss, and ultrasonic pulse velocity. At temperatures of 200 °C, 400 °C, 600 °C, 800 °C, and 1000 °C, the typical fire exposure behavior of concrete was investigated. The effects of two cooling techniques, annealing and quenching, on the residual properties of concrete after exposure to high temperatures were investigated in this study. Replacement of up to 10% of the cement with marble dust and fine sand with foundry sand when concrete is exposed to temperatures up to 400 °C does not influence the behavior of concrete. At temperatures above 400 °C, however, the breakdown of concrete, which includes marble dust and foundry sand, causes a rapid deterioration in the residual properties of concrete, primarily for replacement of more than 10%.

“…From Table 4 , it is observed that carbonation depth of the concrete made with soap solution concentration (i.e., 1% and 2%) decreases to that of concrete made without soap solution. The carbonation depth of concrete made with 1% and 2% soap solution concentration decreased 1 by 1.89% and 46.55%, respectively, compared to that of concrete made without soap solution [ 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 ]. Further, from Table 4 , it is also observed that the change in the carbonation depth of concrete made with partial replacement of cement by different percentages of RHA, i.e., 5%, 10% and 15%, compared to that of concrete made with 1% and 2% soap solution concentration and without RHA are 4.09% and 5.73%, −24.59% and 16.2%, and 22.9% and −113.51%, respectively.…”

The goal of this study was to determine the coefficient of permeability as well as the rate of carbonation of concrete constructed with rice husk ash (RHA) as a partial replacement for cement (i.e., 5%, 10%, and 15%) and two different concentrations of soap solutions (i.e., 1 percent and 2 percent). The microstructural studies of RHA, and carbonated samples have been conducted by using Scanning Electron Microscope (SEM) and X-Ray Diffraction (XRD) analysis. According to this study, the carbonation depth of concrete made with 1% and 2% soap solution concentration and without rice husk ash decreased by 11.89% and 46.55%, respectively. From the results, it may also be observed that the carbonation depth of concrete made with up to 10% replacement of cement by rice husk ash led to maximum carbonation resistance, while more than 10% replacement of cement showed higher carbonation depth. It is also observed that the coefficient of permeability of concrete with 2% soap solution significantly decreased as compared to the 1% soap solution and control mix. It may be observed from the SEM images that 0% soap solution (M1) concrete has a very rough concrete surface which may indicate more voids. However, 2% soap solution concrete has a much smoother surface, which indicates a smaller number of voids. Furthermore, the SEM images showed that the soap solution helps in filling the voids of concrete which ultimately helps in reduction in permeability. Energy Dispersive X-Ray Analysis (EDX) of concrete with 0% (M1) and 2% (M6) soap solution disclosed that the concrete with 2% soap solution (M6) exhibited more silica element formation than the concrete with no soap solution (M1).
