The Reuse of Waste Glass as Aggregate Replacement for Producing Concrete Bricks as an Alternative for Waste Glass Management on Sichang Island

Abstract

The objective of this research is to manage waste glass in Koh Sichang, Chonburi province, used as a partial fine aggregate replacement in concrete brick production. An experimental approach aimed to determine the level of waste glass replacement for the optimal compressive strength. Five samples of 0, 10, 20, 30, and 100% waste glass aggregates by weight were tested at 7, 14, and 28 days. The microstructure and mineralogical phases of the concrete bricks were investigated by scanning electron microscopy and X-ray diffractometry, respectively. The experimental results showed that the compressive strength was improved by increments in replacing waste glass up to 20%; in contrast, the compressive strength was decreased with an increase of waste glass of over 20% in concrete bricks. The optimum compressive strength of concrete brick was 20% by weight, which had the highest values (46.51, 47.41, and 48.49 MPa at 7,14, and 28 days, respectively) and the lowest water absorption. Therefore, waste glass can be used as a partial fine aggregate for producing concrete bricks, and it can be employed as an alternative material for waste glass management.

Sustainable Potentials of Plastics Waste-cement Kiln Dust Blends on Strength Properties of Subbase Soil

“…Reducing the amount of waste materials disposed of is the primary objective of trash recycling, which has an adverse effect on the environment. Recycling of waste materials has also been used to provide substitute materials that encourage the slow decline of natural resources, which are being overused [1][2][3][4][5][6] In most places around the country, flexible roadway is the desired kind of pavement for roads and highways. However, creating and maintaining these types of structures requires a significant amount of non-renewable resources and industrial products, including bitumen, aggregates, subbase, cement, lime and other additives.…”

Incorporação de resíduos de vidro do tipo “garrafas long neck” em blocos de concreto

“…Linked to this consumption, there is the problem of the large generation of glass waste, a non-biodegradable material, which is mostly not recycled and does not return to the manufacturing process, having as final destination the landfills and municipal dumps (TURGUT et al, 2009;RAHIM et al, 2015;KILIÇOĞLU et al, 2017). Among these glass waste, there are the "long neck" type bottles, which end up not being reused due to the high cost of separation, cleaning and transport to the factories (AFSHINNIA et al, 2016;WARNPHEN et al, 2019;FLOOD et al, 2020).…”

“…The civil construction industry has increasingly consumed raw materials, such as natural aggregates, which are mostly non-returnable. The exploitation of these has generated the degradation of the environment and they end up becoming scarce due to the high demand of this sector (MALIK et al, 2013;OGUNDAIRO et al, 2019;WARNPHEN et al, 2019).…”

“…Therefore, glass has been a sustainable and technically efficient alternative to meet the various types of concrete used in civil construction. Due to its physical and chemical characteristics similar to fine aggregate, studies show that the replacement of sand in proportions of approximately 20% by glass residue (RV) has resulted in a gain in compressive strength and a decrease in absorption rates in concrete (ISMAIL et al, 2009;ABDALLAH et al, 2014;WARNPHEN et al, 2019).
