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.

Highlights

  • A huge volume of concrete is used in construction due to its properties of easy molding, higher strength, and durability characteristics [1]

  • It is observed that if the percentage of paper mass gets increased, the water absorption increased. is is due to the phenomenon of absorbing more water by the added paper mass. e results implied that the addition of glass fiber reinforcement comparatively reduces the percentage of water absorption of the specimens. e maximum water absorption of 16.7% and 12.55% is observed in the cases with and without glass fiber addition, respectively. e reason for the higher absorption is due to the paper waste that contains the cellulose materials and thereby absorbs water and retains it for a longer time [34, 35]

  • The following conclusions were drawn: (i) e increase in the incorporation of paper mass tends to increase the percentage of water absorption gradually

Summary

Introduction

A huge volume of concrete is used in construction due to its properties of easy molding, higher strength, and durability characteristics [1]. Due to the usage of cement in concrete production, the emissions and carbon footprint are ever increasing [2]. The accumulation of waste materials from municipal and industrial sources is increasing day by day [3]. E disposal of these waste materials is a point of concern for every municipality or industry [4]. E optimum solution for this problem is to use the waste material in the construction products [8]. Numerous studies are focusing on the energy management [21] and energy efficiency [22] of paper pulpbased products; the available literature on using paper waste in the production of concrete products is scarce [23]. Existing research focused towards the use of paper waste with the ordinary portland cement and water mix. Existing research focused towards the use of paper waste with the ordinary portland cement and water mix. is kind of product was termed “Paper Crete.” With the use of this new material, blocks were manufactured and tested for the structural properties such as modulus of elasticity and thermal and bond characteristics [24, 25]
