Force‐Deformation Study on Glass Fiber Reinforced Concrete Slab Incorporating Waste Paper

Abstract

This study inspects the viability of engaging the discarded paper wastes in concrete by varying the volume proportions from 0%–20% with each 5% increment in replacement of the weight of cement. A physiomechanical study was conducted, and the results were presented. A glass fiber reinforced rectangular slab with a longer span (ly) to shorter span (lx) ratio of (ly: lx) 1.16 was cast with optimum replacement of waste-paper mass and compared the force-deformation characteristics with the conventional concrete slab without waste paper. The optimum percentage of discarded papers for the replacement of cement is 5%. Also, the results imply that the compressive strength at the age of 28 days is 30% improved for the optimum replacement. Based on the outcomes of the investigation, it can be inferred that the compressive strength gets progressively reduced if the volume of the discarded paper gets increases. The incorporation of glass fibers improves the split and flexural strength of the concrete specimens considerably. The ultimate load-carrying capacity of the glass fiber reinforced waste paper incorporated concrete slab measured 42% lower than that of the conventional slab. However, development of the new type of concrete incorporating waste papers is the new trend in ensuring the sustainability of construction materials.

Development and Characterization of Carbon‐Based Adsorbents Derived from Agricultural Wastes and Their Effectiveness in Adsorption of Heavy Metals in Waste Water

“…The agricultural waste and peanut shells were characterized for the proximate test, calorific quantity, and ultimate analysis. The peanut shell characterization results in Table 1 show that peanut shells have a great potential application for heavy metal removal in industrial effluent by pyrolysis, as this biomass contains less than 10% [ 30 ]. The other important parameter in biomass is its volatile content percentage.…”

Experimental Study On Greener Fine Aggregates (Steel Slag) In Concrete

“…Cement mortar mix proportion 1:2, 1:2.5 and w/c ratio 0.3,.35 with various % of SS were designed. Praburanganathan, et al (2022) from the terms of unit weight and compressive strength, the act of the mortar was evaluated. Selvaraj, et al (2022) report the study the concrete mortar with SS aggregate to investigates the early age shrinkage.…”

Study on Performance of Infilled Wall in an RC-Framed Structure Using a Reinforcing Band

“…At present, the development of tall construction is necessary to avoid more utilization of land area for building up the structure in the urban community [1,2]. At the same time, the e ects of earthquake in tall structures have been severely damaged due to out of uncontrolled lateral displacements and it makes serious damages to the structural elements [3,4].…”
