Self-flowing mortar (SFM) is being popular in recent time. Its' easy-placement nature makes it suitable for narrow or congested reinforced places. To comply with modern-age needs, many supplementary cementitious materials (SCMs) are gaining importance nowadays. Using industrial and agricultural wastes as SCM, ensures proper management of many hazardous materials and saves cost as well. Incorporation of these two techniques can offer cost-effective and environment-friendly solutions to many construction problems. Many researchers studied the effect of different SCMs on mortar properties in recent years. The objective of this study is to summarize the findings of recent experiments. This will help the experts of this field to optimize their mix design easily, as well as, the researchers to find the research gap and determine the direction of their future studies.

“…In an experiment conducted by Khotbehsara et al (2015), the sample containing 30% FA showed more flow value with 42% less superplasticizer than the mix without FA [1]. A similar effect was observed in the study of Parghi & Alam (2016). Silica fume (SF) shows a consistent reduction in fluid nature of mix up to 25% replacement [2].…”

“…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). De Azevedo et al (2017) investigated the influence of wastes (85% of particles smaller then 100 µm) from the wastewater treatment plant of the glass polishing process in the rheological properties of adhesive mortar with partial replacement of cement and fine aggregate (up to 20%).…”

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.

“…As a consequence of its high silica content [18][19][20], glass powder has been proposed as a supplementary cementitious material, and studies have pointed out that glass has pozzolanic properties when the particle size of the material is less than 75 µm [16][17][18][19]. The recycled glass powder has potential for improving the physical and mechanical properties of mortars [21], such as drying shrinkage [20] and resistance against chloride ingress [17,20], as well as a reduction in the heat of hydration [22]. With the aim of controlling the loss of mechanical properties, Khmiri et al [23] have used a design method in order to optimise the glass powder and cement binder, finding that the ideal binder is prepared with 20% glass powder and 80% cement.…”

Influence of Waste Glass Powder Addition on the Pore Structure and Service Properties of Cement Mortars

At present, reusing waste constitutes an important challenge in order to reach a more sustainable environment. The cement industry is an important pollutant industrial sector. Therefore, the reduction of its CO 2 emissions is now a popular topic of study. One way to lessen those emissions is partially replacing clinker with other materials. In this regard, the reuse of waste glass powder as a clinker replacement could be possible. This is a non-biodegradable residue that permanently occupies a large amount of space in dumping sites. The aim of this work is to study the long-term effects (400 days) of the addition of waste glass powder on the microstructure and service properties of mortars that incorporate up to 20% of this addition as clinker replacement. The microstructure has been characterised using the non-destructive impedance spectroscopy technique and mercury intrusion porosimetry. Furthermore, differential thermal analysis was also performed. Compressive strength and both steady-state and non-steady-state chloride diffusion coefficients have also been determined. Considering the obtained results, mortars with 10% and 20% waste glass powder showed good service properties until 400 days, similar to or even better than those made with ordinary Portland cement without additions, with the added value of contributing to sustainability.
