“…(2) Recycle that part of glass that would otherwise end up in landfills and thus greater eco-sustainability throughout the production cycle. (3) More architectural value of mortars/concretes since the visible coloured glass particles will produce a pleasing visual effect on the surfaces where the mortar is applied (Ling and Poon 2014). These mortars/concretes, due to their esthetical properties, can satisfy not only traditional properties but also decorative functions for fair-faced concrete finishes, both in external and indoor applications.…”

“…Supplementary cementitious materials, such as fly ash (FA) (Kou and Poon 2009;Parghi and Shahria Alam 2016), metakaolin (MK) (Guo et al 2015;Ling and Poon 2011), ground granulated blast furnace slag (GGBS) (Ling and Poon 2014;Li et al 2017) and nanosilica (Sikora et al 2016;Aly et al 2012) are well-known to be able in reducing the alkali-silica reaction in concrete because the amount of alkali hydroxide can be reduced by the pozzolanic reaction (Carsana et al 2014; Shayan and Xu 2004;Topçu et al 2008;Corinaldesi et al 2016). Also fine glass powder (d < 150 μm) is effective in suppressing ASR thanks to its pozzolanic activity (Bignozzi et al 2015;Parghi and Shahria Alam 2016;Afshinnia and Rangaraju 2015;Nunes et al 2013;Serpa et al 2013).…”

The possibility of recycling mixed colour waste glass as it is for manufacturing decorative architectural mortars, has been investigated. In mortars, the 0-33-66-100% of calcareous gravel volume has been replaced with recycled glass cullets, with no other inorganic addition. To mitigate the possible alkali-silica reaction, mixes with a hydrophobic admixture were also compared. The obtained results show that the replacement of calcareous gravel with glass cullets of similar grain size distribution permits to reduce the dosage of the superplasticizer admixture to obtain the same workability of fresh mortar; it does not affect significantly the mechanical performances, the water vapour permeability and the capillary water absorption but it reduces significantly the drying shrinkage deformation. The used recycled glass is classified as no reactive in terms of alkali-silica reaction neither in water nor in NaOH solution following the parameters of the current normative, even in the absence of the hydrophobic admixture. The hydrophobic admixture further delays the expansion trigger but not the speed of its propagation.

“…Glass is quite easily segregated from other residues, and the study of its physical and chemical characteristics has led to experimentation in its ability to replace "natural" sands in mortars and concrete [13]. is type of praxis is considered ecofriendly, of particular interest in certain construction applications (waterproofing in the structure, resistance properties, durability, and aesthetics), and even on occasion for its profitability [4,14]. However, for the residue to bond effectively with the matrix of these composites, its properties and resulting products must be established, in order to ensure the suitability of the new recycled composite for use in construction [13].…”

Due to the current problems related to the generation of diverse wastes and the extraction of nonrenewable materials to be used in the construction sector, the alternative use of waste glass could be a sustainable option with environmental and economic benefits, in case of being feasible its use as a replacement of the usual aggregates to manufacture recycled mortars. In this research, one presents a study of the fresh-state properties of the mortars containing 15, 30, 60, and 100% recycled glass aggregates as a replacement for the usual aggregate, providing the experimental results of consistency, density, and air content. Using the experimental results, and by means of a numerical and statistical analysis of these, a diagram of triple interaction that allows us to unify the behavior of the studied properties is constituted; making feasible with this, the prediction of the behavior of these properties with respect to variables as their ratio water/cement, aggregate/cement, and different percentages of replacement of aggregates.

“…A considerable number of studies have focused on the alkali-silica reaction during cement hydration [7,8]. For instance, in concrete with 100% waste glass aggregate, ground granulated blast furnace slag (GGBS) can be used to partly replace white cement to reduce the alkali-silica reaction and improve the performance of concrete, including the working performance, flexural strength at 28 days, dry shrinkage, ASR risk and acid resistance of concrete [9].…”

An Experimental Study on Water Permeability of Architectural Mortar Using Waste Glass as Fine Aggregate

This paper investigates the water permeability, consistency and density of architectural mortar with various contents of glass sand as fine aggregate. To reduce the effect of alkali-silica-reaction (ASR), metakaolin (MK) was used as supplementary cementitious material (SCM) instead of a component of white cement. The microstructure of glass sand mortar was visualized by means of scanning electron microscope (SEM) images. The experimental results showed that the permeability of the mortar increased with the glass sand, reaching its maximum at about 60–80% glass sand content. The optimum MK content varied with the content of glass sand, and higher content of MK was required for 60% glass sand. In addition, the consistency and density of mortar had a negative correlation with the increase of glass sand.
