“…However, when the concrete is boiled in hot water, the RuC shows a higher water absorption value than conventional concrete. Similar results of the water absorption of RuC are found in past studies 22,61,62 . The disintegration of rubber crumbs trap water adjacent to the concrete structure and generates interfacing zones prone to high water absorption, which might cause an increase in water absorption when the R3 mix is boiled.…”

“…Furthermore, the inclusion of PPC increases the amount of hydration products, which slows the disintegration of cement paste, resulting in superior concrete mix performance. Many researchers found similar outcomes on utilizing different kinds of supplementary pozzolanic materials in the concrete mixtures exposed to acid attack 62,63,66,68,69 . The spacing between rubber crumbs and binder in RuC, as well as the porosity caused by rubber crumb particles, allowed H 2 SO 4 and HCl ions to permeate the concrete, increasing Ca(OH) 2 and CSH dissolution.…”

Investigations of the effect of acids and freeze-thaw on pozzolanic cement-based rubberized concrete after surface treatment of rubber crumbs are limited. Rubberized concrete's mechanical and durability properties (water absorption, acid attack resistance, and freeze-thaw attack resistance) are evaluated. Six rubber crumbs content (0%, 10%, 15%, 20%, 25%, and 30%) and particle size 0.6-2.36 mm are used to replace fine aggregate in concrete partially, and 15% replacement level of rubber crumb is found to be the optimum quantity in concrete. Structural analyses show that the specimens remain in the crystalline phase after being submerged in H 2 SO 4 and HCl acid. When rubberized concrete is immersed in H 2 SO 4 and HCl solution with equal concentrations and duration, specimens immersed in HCl solution have been found to have less surface erosion, less weight loss, and lower compressive strength loss. When the conventional concrete mix is immersed in H 2 SO 4 and HCl solution, the losses in compressive strength are 74.56% and 30.34%, but in rubberized concrete, the losses are 60.01% and 24.22% only. No apparent microcracks and no spalling on the surfaces of the specimens are found up to 90 freeze-thaw cycles. Rubberized concrete's ultrasonic velocity decreases slightly up to 90 freeze-thaw cycles, but it still has good concrete quality.

“…The extraction of natural river sand and stone chips for concrete construction is increasing day by day, paving us to a shortage of natural resources. The extraction of river sand causes a change in river bed level and hydrological strata, affecting the regular stream directions [ 1 , 2 , 3 ]. Furthermore, cement production requires substantial energy and emits a large amount of carbon dioxide [ 4 , 5 ].…”

Waste Glass in Cement and Geopolymer Concretes: A Review on Durability and Challenges

Every year, the world is producing around 100 metric tons of waste glass (WG), the majority of them are going to landfills that create massive environmental problems. One approach to solve this problem is to transform waste glass into construction materials. Glass is recyclable; however, the melting temperature of the glass is highly dependent on its colour that requires sorting before recycling. To overcome this challenge, many researchers and end-users are using broken glass in concrete either as a binder or aggregates. While significant investigations have done in this area, however, the outcomes of these studies are scattered, and difficult to reach a firm conclusion about the effectiveness of WG in concrete. In this study, the roles of WG and its impact on microstructural and durability properties for both cement and geopolymer concrete are critically reviewed. This review reveals that the amorphous silica in WG effectively participate to the hydration and geopolymerization process and improve concrete microstructural properties. This behaviour of WG help to produce durable concrete against shrinkage, chemical attack, freeze-thaw action, electrical and thermal insulation properties. The optimum replacement volume of binders or natural aggregates and particle size of WG need to be selected carefully to minimise the possible alkali-silica reaction. This review discusses a wide range of parameters for durability properties and challenges associated with WG concrete, which provides necessary guidelines for best practice with future research directions.

“…Concrete casting requires natural sand and natural stone aggregates, which are around 20-30% and 60-70% of concrete volume. Excessive extraction of natural sand and stone aggregates may also result in resource shortages [18,19]. Mining of natural river sand causes changes in the direction of river flows and alters hydrological strata and river bed levels [20].…”

Recent research has revealed the promising potential of using waste glass (WG) as a binder or inert filler in cement and geopolymer concrete to deliver economic and environmental benefits to the construction sector. However, the outcomes obtained by different research groups are scattered and difficult to compare directly because of isolated process parameters. In this study, the roles and impacts of WG and process parameters on the performance of WG-added cement and geopolymer concrete are critically reviewed. This study reveals that the chemical and mineralogical composition, and particle size of WG, mix proportion, activation, and curing condition of concrete are the most important parameters that affect the dissolution behavior of WG and chemical reactivity between WG and other elements in concrete; consequently, these show impacts on properties of concrete and optimum WG level for various applications. These parameters are required to be optimized based on the guidelines for high pozzolanicity and less alkali–silica reactivity of WG in concrete. This review provides a critical discussion and guidelines on these parameters and the chemistry of WG in cement and geopolymer concrete for best practice and highlights the current challenges with future research directions.
