“…The drying shrinkage of the HPC is very low, about one third of that of the CC, due to its low w/b that limits the evaporation of free water and correlatively the drying shrinkage. Shayan et al [8] also reported similar trends. These results suggest that the G concrete may have less or similar deformation and lower risk of cracking due to drying shrinkage than a control.…”

Abstract. Ground-glass pozzolan (G) obtained by grinding the mixed-waste glass to same fineness of cement can act as a supplementary-cementitious material (SCM), given that it is an amorphous and a pozzolanic material. The G showed promising performances in different concrete types such as conventional concrete (CC), high-performance concrete (HPC), and ultra-high performance concrete (UHPC). The current paper reports on the characteristics and performance of G in these concrete types. The use of G provides several advantages (technological, economical, and environmental). It reduces the production cost of concrete and decrease the carbon footprint of a traditional concrete structures. The rheology of fresh concrete can be improved due to the replacement of cement by non-absorptive glass particles. Strength and rigidity improvements in the concrete containing G are due to the fact that glass particles act as inclusions having a very high strength and elastic modulus that have a strengthening effect on the overall hardened matrix.

“…The concrete industry is one of the potential ways of reusing millions tons of glass cullet per year either as aggregate or supplementary cementitious material (SCM) (Mirzahosseini and Riding 2014). Although work on the use of finely ground glass as a pozzolanic material also started as early as 1960s, most of the work in this area is relatively recent, and has been encouraged as a result of continual accumulation of waste glass and its consequent environmental issues (Shayan and Xu 2006). On the other hand, limited work (one study by this time) has been carried out on the application of ground glass as SCM in SCC (Liu 2011).…”

The successful completion of the present research would be achieved using ground waste glass (GWG) microparticles in self-consolidating concrete (SCC). Here, the influences of GWG microparticles as cementing material on mechanical and durability response properties of SCC are investigated. The aim of this study is to investigate the hardened mechanical properties, percentage of water absorption, free drying shrinkage, unit weight and Alkali Silica Reaction (ASR) of binary blended concrete with partial replacement of cement by 5, 10, 15, 20, 25 and 30 wt% of GWG microparticles. Besides, slump flow, V-funnel, L-box, J-ring, GTM screen stability, visual stability index (VSI), setting time and air content tests were also performed as workability of fresh concrete indicators. The results show that the workability of fresh concrete was increased by increasing the content of GWG microparticles. The results showed that using GWG microparticles up to maximum replacement of 15 % produces concrete with improved hardened strengths. From the results, when the amount of GWG increased there was a gradual decrease in ASR expansion. Results showed that it is possible to successfully produce SCC with GWG as cementing material in terms of workability, durability and hardened properties.

“…The fact that glass has a high silica content has led to laboratory studies on its feasibility as a raw material in cement manufacture [9,10]. The use of finely divided glass powder as a cement replacement material has yielded positive results [11][12][13][14][15][16]. Glass is amorphous with a high silica content, thus making it potentially pozzolanic when the particle size is less than 75 μm [12].…”

This paper deals with studies on the use of waste glass powder as an effective ingredient in concrete. Studies on cement pastes including mechanical property tests and thermal analysis were used to understand the influence of the glass powder on the cement hydration process and to arrive at an optimal dosage range. Cast-in-place concrete and block mixtures were proportioned with varying dosages of glass powder, and tests for mechanical properties, alkali-silica reaction, and water absorption were carried out. The use of fly ash as a cement replacement material was also adopted in one of the concrete mixtures to compare the performance of glass powder and fly ash in concrete. Though the complete effect of cement dilution was not overcome by the chosen dosage of glass powder, the strength results were comparable to that of control concrete. Moisture intake results of glass powder modified concrete mixtures showed lower total water absorption as well as sorptivity than the control concrete when cured for a longer duration. The expansion due to alkali-silica reaction was also lower for the glass powder modified mixtures. For the concrete block mixtures, it was found that moist curing the blocks after initial steam curing was beneficial in strength improvement. Replacement of 10% cement with glass powder was found to result in equal or higher compressive strengths of the blocks. In regions where glass powder is locally available, its use as a cement replacement material presents an efficient waste management option, without compromising concrete performance.
