“…The SA materials consisted of irregularly shaped particles, the BF slag consisted of rounded, semi-spherical, and irregularly shaped particles and the glass fiber consisted of rounded-shape particles, as shown in Figure 17A-C. Finally, more or less similar mechanical and microstructural behaviors of waste material replacements reinforced by different types of fibers have been reported by several researchers (Horvath, 1998;Liu et al, 2006;Matsuda et al, 2008;Landa-Ruiz et al, 2021;Althoey et al, 2022;Najm et al, 2022b;Memon et al, 2022;Nanayakkara et al, 2022;Prabhath et al, 2022). Since a lower percentage of C/SA results in a specimen that does not retain its shape even after the curing period, and this value was used as 10% while making specimens for the compressive and flexural tests.…”

The sugar industry produces a huge quantity of sugar cane bagasse ash in India. Dumping massive quantities of waste in a non-eco-friendly manner is a key concern for developing nations. The main focus of this study is the development of a sustainable geomaterial composite with higher strength capabilities (compressive and flexural). To develop this composite, sugarcane bagasse ash (SA), glass fiber (GF), and blast furnace slag (BF) are used. Ash generated from burning sugar cane in the sugar industry is known as sugar cane bagasse. To check the suitability of this secondary waste for use in civil engineering and to minimize risk to the environment in the development of sustainable growth, a sequence of compressive and flexural strength tests was performed on materials prepared using sugar cane bagasse ash (SA) reinforced by glass fiber (GF) in combination with blast furnace slag (BF) and cement (CEM). The effects of the mix ratios of glass fiber to bagasse ash (0.2%–1.2%), blast furnace slag to the weight of bagasse ash (10%), cement binding to bagasse ash (10%–20%), and water to sugar cane bagasse ash (55%) regarding the flexural strength, compressive strength, density, tangent modulus, stress–strain pattern, and load–deflection curve of the prepared materials were studied. According to the findings, compressive strength achieved a maximum strength of 1055.5 kPa and ranged from 120 to 1055.5 kPa, and the flexural strength achieved a maximum strength of 217 kPa and ranged from 80.1 to 217 kPa at different mix ratio percentages. The value of the initial tangent modulus for the cube specimens ranged between 96 and 636 MPa. For compression specimens with 20% cement, the density decreased from 1320.1 to 1265 kg/m3, and the flexural strength decreased from 1318 to 1259.6 kg/m3. With limitation in lower percentages of C/SA, the specimen cannot sustain its shape even after curing period. In comparing the previous research with the present experimental work, it was observed that the material proposed here is lightweight and can be utilised as a filler substance in weak compressible soils to improve their load-bearing capacity.

“…In this study, the optimum dosage of NRL in quantity is 1%, and beyond that proved to only contribute to the decrease in compressive strength. Tis inferior performance of concrete strength observed as NRL was increased has been noted in similar tests [19][20][21][22]. 3.2.9.…”

The exposure of concrete to elevated temperatures is known to cause diverse severe damages in concrete composites. Hence, measures to improve the performance of concrete during exposure to fire are continually proposed. The present study investigated the postfire residual strength and morphology of concrete incorporating natural rubber latex exposed to elevated temperature. Four different concrete mixes were considered for the investigation, namely, a control sample made without natural rubber latex, the second sample containing 1% natural rubber latex, the third sample containing 1.5% natural rubber latex, and the fourth sample containing 3% of natural rubber latex. The concrete samples (150 mm cubes and 100 × 200 mm cylinders) were exposed to varying temperatures 300°C, 800°C, and 1000°C, after the curing process. Nondestructive tests using Schmidt rebound hammer and ultrasonic pulse tester were carried out on samples. The compressive strength and split-tensile strength of concrete cubes and cylinders, respectively, were determined. Micrographs and elemental distribution in the sample were studied using the scanning electron microscopy (SEM-EDX) apparatus. It could be seen from the results that the concrete strength properties reduced as the exposure temperature increased. The results also showed that NRL could be sparingly utilized as a concrete admixture, at 1% content. The performance of concrete was not stable at over 300°C when NRL addition was above 1%.

“…Experimental methods were used in this study. That is, test specimens were made and tested in the laboratory to determine the effect of fiber as an additive on compressive and split tensile strength [5,[22][23][24]. Planning a concrete mix with a design rating of 25 MPa begins with determining the slump value, reviewing the plan, then determining the amount of water for the concrete mix, the amount of water needed to be drawn from determining.…”

The use of rattan and bamboo fibers increases the compressive strength, tensile strength and improves the ductility of concrete. Shell ash also contains pozzolanic compounds that can improve the properties of concrete. In this study, rattan and bamboo were used as concrete fibers and seashell ash was used as filler. The purpose of this study is to measure the compressive and tensile strength of concrete. In this study, rattan and bamboo fibers were added to the concrete mix with a mix design 25MPa. The additive variation is 0%, 0.5%, 1%, 1.5%, 2%. The results showed that the average compressive strength at 28 days was 0.26.29 MPa, 0.5, 19.71 MPa, 1.21.69 MPa, 1.5, 24.72 MPa and 2.18 MPa. Accordingly, the average tensile strength after 28 days was 0.736 MPa, 2,359 MPa, 2,312 MPa, 2.453 MPa and 2,595 MPa. These results show that the addition of rattan and bamboo fibers to concrete can increase the crack resistance of concrete, while the optimal increase in compressive strength with the addition of rattan fiber is achieved only with the change of 1.5%. This indicates that the addition of 1.5% natural fibers improves the tensile strength of concrete.
