“…The concrete properties were analysed with ABAQUS software. The damage in the specimen surpassed its tensile stress when the concrete fracture strain was exceeded [ [58] , [59] , [60] , [61] , [62] , [63] , [64] , [65] , [66] , [67] , [68] , [69] , [70] ]. Similar to what was found in the experiment, the FRPRCB under tensile stress had been deformed in ABAQUS simulation.…”

“…Adopting this material in concrete becomes even more crucial as a result. According to data on fracture toughness, concrete is at least a hundred times more susceptible to crack propagation than steel employed as reinforcement [10][11][12][13][14][15]. This study investigates the viability of replacing some of the cement in new concrete with solid waste ash.…”

Aim: This investigation looked at the effects of Novel Hypo Sludge and Sikacrete on concrete with the main objective of improving its mechanical qualities. To Assess the flexural and compressive strengths, and other mechanical properties of concrete when mixed with Novel Hypo Sludge and Sikacrete. Materials and Methods: The use of SikaCrete and partial substitution of innovative hyposludge (paper pulp) in cement enhance the flexural strength of concrete when compared to M30 grade conventional concrete. Results: In this experiment, the flexural strength of grade M30 concrete was tested after 28 days using a beam mould with dimensions of 500 mm x 100 mm x 100 mm. The experiment looked at the effects of adding hypo sludge in the range of 30% on the strength qualities of concrete.The findings of the tests show that the novel hypo sludge-infused concrete performs better than cement-only concrete. The novel hypo sludgeadded concrete had an average flexural strength of 19.31 N/mm2 compared to conventional concrete with an average flexural strength of 16.59 N/mm2. From the statistical analysis the significant value is computed as p value=0.000, (p<0.05), twotailed and is considered as statistically significant in the accuracy rate when comparing both Novel Hypo sludge and Conventional concrete. Group statistics for this 30% novel hyposludge concrete sample group Standard deviation (0.47883, 0.66145), mean (16.5889, 19.3111), and standard error (0.11286, 0.15591). Conclusion: As a consequence, the performance of HSC put through the flexural strength test can be significantly improved by adding Novel Hyposludge (Paper Pulp) to Cement and SikaCrete.

“…One potential approach to recycle this wastepaper obtained from discarded plasterboard involves its use as a reinforcing fiber material within concrete. The recycling of the wastepaper as a fiber within the concrete offers an effective solution to both the building sector and environmental preservation [ 11 ]. Converting one metric ton of the wastepaper is equivalent to safeguarding 17 trees, conserving 4102 kilowatt-hours of energy, preserving 2600 L of water, and averting the emission of 27 kg of hazardous substances into the atmosphere [ 12 ].…”

“…The existing literature contains only a few studies on the recycling of paper fibers in cementitious materials (e.g., paste [ 13 ], mortar [ 14 , 15 ], and concrete [ 16 , 17 , 18 , 19 ]). Previous studies have employed paper fibers sourced from discarded office paper, newspapers, packaging materials, cardboard, magazines, and pamphlets in the cementitious materials [ 11 ]. It is important to highlight that paper fibers, being of a cellulosic nature, are appreciated for their strength, flexibility, and their ability to create a cohesive network when combined with cementitious materials.…”

This study evaluates the potential use of discarded plasterboard paper as fibers from buildings to reinforce concrete. Various concentrations of wastepaper fibers (0.5%, 1%, 1.5%, 2%, and 2.5% by weight of the binder) were investigated in this research. To mitigate the water absorption effect of the paper fibers, metakaolin was employed as a partial cement replacement. The results demonstrate that the inclusion of the wastepaper fiber enhances the mechanical and durability performance of the concrete. The optimal fiber proportion was identified as 1%, leading to a 29% increase in the compressive strength, a 38% increase in the splitting tensile strength, a 12% decrease in the water absorption, and a 23% decrease in the drying shrinkage with respect to the concrete containing 20% metakaolin. However, exceeding this optimal fiber content results in decreased mechanical and durability properties due to the fiber agglomeration and non-uniform fiber distribution within the concrete matrix. Based on the microstructural analysis, the improved performance of the concrete is ascribed to decreased porosity, more refined pore structure, and reduced propagation of microcracks within the concrete matrix in the presence of wastepaper fiber. According to the results, concrete containing 20% metakaolin and 1% wastepaper fiber exhibits durability and mechanical properties comparable to those of the traditional concrete. This finding highlights the significant promise of reducing dependency on conventional cement and incorporating suitable recycled materials, such as discarded plasterboard, and secondary by-products like metakaolin. Such a strategy encourages the preservation of resources, reduction in carbon dioxide emissions, and a decrease in the ecological footprint resulting from concrete production.
