1. Introduction
Supplementary cementitious materials (SCMs) have been used widely to partially replace Portland cement in concrete. For instance, the cement manufacturers in Europe have substituted 25% of cement clinkers with other SCMs, in the past 20 years [1]. Utilization of SCMs such as fly ash from coal combustion, or silica fume from silicon and ferrosilicon alloy production, or blast furnace slag from pig iron production, as cement replacement represents a value-added approach to address the environmental concerns. As such, not only the energy consumption and carbon dioxide emission could be reduced during the cement manufacturing process, environmental advantages could also be obtained with respect to reduction in solid waste disposal and landfills. Compared to those SCMs from industrial by-products, calcined clay is believed to have even greater potential to address the environmental impact of cement and concrete in the future, considering its availability on the earth [2,3]. On the other hand, another form of SCM, glass powder, should not be ignored due to its silica rich nature and huge amount of disposal globally. It was estimated that the global disposed solid waste was 200 million tons in 2004, 7% of which was glass products [4]. In 2013, 11.54 million tons of waste glass was generated in United States and only 27.3% was reused [5]. Waste glasses were normally disposed into landfills if not recycled. Previous studies indicated the potential use of waste glass as constituent in concrete, such as in the form of aggregates [6e8], filler [9], alkali activated binder [10], and SCM [11e28]. The latter could bring about more economical and sustainable impact to the society. Shao et al. [11] first reported that glass powder could exhibit pozzolanic activity if finely grounded to below 38 mm. Concrete with 30% glass powder as SCM showed lower compressive strength before 28 days but increased strength at 90 days, attributed to the pozzolanic reaction of glass powder. Similar to other SCM, pozzolanic activity of glass powder increases with decreasing particle size [11,12] and higher curing temperature [13,14]. Dyer and Dhir [15] found that the cement hydration was accelerated by the replacement of glass powder, due to the dissolution of alkalis from the glass particle. However, the amount of released alkalis is insuffi- cient to compensate the hydration and early age strength reduction caused by the cement dilution. Similar findings were reported by Schwarz et al. [16], and Du and Tan [17]. Schwarz et al. [18] investigated the durability characteristics of concrete containing 10% glass powder as cement replacement and revealed that the chloride ingress and water intake were both reduced. However, its compressive strength was lower than plain cement concrete at each testing age up to 90 days. Matos and Sousa-Coutinho [19] examined the durability characteristics of mortar with cement substituted by glass powder by 10% and 20% and found that water sorptivity was not affected and carbonationresistance decreased with glass powder inclusion, while the chloride diffusion was lowered. At a high content of 30%, Carsana et al. [20] reported that the long term pozzolanic activity of glass powder, up to 7 years, was superior to natural pozzolans and similar to fly ash.
