The study focused on the feasibility of recycling sugarcane bagasse ash (SCBA) to produce container glass. The bagasse was calcined through a Gallenkamp muffle furnace at 6000C and then held at 7000C for 1 ½ hrs and large amount of bagasse ash was obtained. 30 and 18 mesh sieves were used simultaneously to produce a fine powdered of the materials. 5g of SCBA sieved, calcium carbonate and sodium carbonate were passed through atomic absorption spectrophotometer. The result reveals SiO2 76.34wt%, Al2O3 8.55wt%, Fe2O3 2.93wt%, Na2O 0.12wt%, TiO2 0.80wt%, K2O 1.50wt%, CaO 0.07wt%, SO3 2.25wt%, Cr2O3 0.05wt%, Mn2O3 0.06wt% and LOI 6.42wt%. Interestingly, the ash contained high amount of silica of 76.34wt% which could supply all SiO2 needed to produce soda lime silica glass. A container glass batch composition was formulated from 95.899g of SCBA, 19.220g of CaCO3 and 25.556g of Na2CO3 and fired in muffle furnace at temperature between 11000C-12000C for 3 hours. The resulting glass was amber in colour which signifies the presence of iron oxide (Fe2O3) and sulphur trioxide (SO3) in bagasse ash. This implies that the ash can be used to produce amber glass for beverages and storing pharmaceutical drugs especially those which are sensitive to light.

Batch modification with low-enthalpy raw materials is the effective approach for reducing the glass melting energy. In the previous study, it was found that introducing wollastonite (CaSiO3) as a source of CaO instead of calcium carbonate (CaCO3) in the soda-lime glass batch can fasten the melting process. It is because the modified batch with CaSiO3 has lower chemical heat demand, ΔHochem, which is equivalent to the standard heat of batch-to-melt conversion. In order to investigate the kinetic property of the modified batch, the melting behaviour of 2 kg modified batch was studied. The results showed that the temperature of the modified batch increased at a faster rate than the original batch. The properties of the glass from the modified are also similar to the original batch.

This study aims to provide a thermophysical characterization of a new economical and green mortar. This material is characterized by partially replacing the cement with recycled soda lime glass. The cement was partially substituted (10, 20, 30, 40, 50 and 60% in weight) by glass powder with a water/cement ratio of 0.4. The glass powder and four of the seven samples were analyzed using a scanning electron microscope (SEM). The thermophysical properties, such as thermal conductivity and volumetric specific heat, were experimentally measured in both dry and wet (water saturated) states. These properties were determined as a function of the glass powder percentage by using a CT-Meter at different temperatures (20 °C, 30 °C, 40 °C and 50 °C) in a temperature-controlled box. The results show that the thermophysical parameters decreased linearly when 60% glass powder was added to cement mortar: 37% for thermal conductivity, 18% for volumetric specific heat and 22% for thermal diffusivity. The density of the mortar also decreased by about 11% in dry state and 5% in wet state. The use of waste glass powder as a cement replacement affects the thermophysical properties of cement mortar due to its porosity as compared with the control mortar. The results indicate that thermal conductivity and volumetric specific heat increases with temperature increase and/or the substitution rate decrease. Therefore, the addition of waste glass powder can significantly affect the thermophysical properties of ordinary cement mortar.

Waste glass is cementitious in nature when it is finely ground, and especially when it is ground in a wet environment it can be finer than Portland cement. The obtained borosilicate lamp waste glass slurry with a grain size of 0.713 – 8.088 μm has shown better fineness and stability to segregation in comparison to soda-lime and soda-alkaline earth-silicate waste glasses. Elaborated high efficiency concrete with borosilicate lamp waste glass showed 120 MPa compressive strength at 28 days and it can be considered as ecological due to reduced cement content for 20% in concrete mixture without changing concrete properties in a negative way, reduced CO2 and waste glass deposits.

The utilization of solid waste materials or industrial waste as partial substitution of cement is growing in construction industry all around world. Less cement consumption causes consequently reduction in CO2 emission into the atmosphere and reduction in energy consumption. This paper examines the possibility of using finely ground waste glass as a partial replacement for cement and as a sealing admixture. Glass powder used in the research was prepared from the glass waste obtained from a local recycling company. Glass cullet made of brown glass, which after rinsing to remove sugars and other impurities, was dried and ground to a fraction below 125 μm.This paper is the revised version of the paper that has been published in the Proceedings of the Creative Construction Conference 2018 (Horszczaruk and Brzozowski, 2018).

A responsible approach towards sustainable development requires the use of environmentally friendly, low-carbon, and energy-intensive materials. One positive way is to use glass waste as a replacement for fine natural aggregate. For this purpose, the effects of adding glass cullet to the mechanical properties of mortar were carried out. The glass aggregate made from recycled post-consumer waste glass (food, medicine, and cosmetics packaging, including mostly bottles), were used. This experimental work included four different contents of fine glass cullet (5, 10, 15, and 20 wt.% of fine aggregate). The compressive, flexural, and split tensile strengths were evaluated. Moreover, the modulus of elasticity and Poisson coefficient were determined. The addition of glass sand aggregate increases the mechanical properties of mortar. When comparing the strength, the obtained improvement in split tensile strength was the least affected. The obtained effect for the increased analysed properties of the glass sand aggregate content has been rarely reported. Moreover, it was determined that by increasing the recycled glass sand aggregate content, the density of mortar decreased. In addition, the relationships between the properties for mortar containing glass sand aggregate were observed.
