The effect of hydrothermal activation indifferent temperature and pressure conditions on the pozzolanic activity of waste glass powder was discussed. The waste glass powder was treated at 108°C, 0.15MPa, 116°C, 0.18MPa and 121°C, 0.2MPa for 2h in an autoclave respectively after milling to 4215cm2/g. Mortar was made with untreated and hydrothermal activated waste glass power replacement of cement at 20% respectively, then tested for compressive strength at 3, 7, 14 , 28 and 90 days. Results showed that compressive strength of cement mortar had varying degrees of decline when replacing cement with untreated waste glass powder, comparing to the control one. Decline amplitude was large at early age and small at late age. Activity of waste glass powder was significantly improved after hydrothermal treatment. Compressive strength of mortar improved as temperature and pressure elevated, obtaining optimal strength at 121°C, 0.2MPa. Compressive strength of mortar with hydrothermal activated glass powder was higher than that with untreated glass powder at all age with 20% cement replacement. Compressive strength increased 5.3% ~ 13.6% at 3 d, 6.8%~9.7% at 28 d, 9.7% ~ 17.7% at 90 d. The essence of hydrothermal activation was the corrosion of water in the glass.

Self Compact Concrete

In this work, waste glass powder from broken windows and plastic fibers from waste polyethylene terephthalate bottles are utilized to produce an economical self-compact concrete. Fresh properties (slump flow diameter, slump Flow T50, V. Funnel, L–Box), mechanical properties (Compressive strength and Flexural strength) and impact resistance of self-compact concrete are investigated. 15% waste glass powder as a partial replacement of cement with five percentages of polyethylene terephthalate plastic waste were adopted: 0% (reference), 0.5%, 0.75%, 1%, 1.25% and 1.5% by volume. It seems that the flow ability of self-compact concrete decreases with the increasing of the amount of plastic fibers. The compressive strength was increased slightly with plastic fiber content up to (0.75%), about 4.6% For more than (0.75%) plastic fiber. The compressive strength began to decrease about 15.2%. The results showed an improvement in flexural strength and an impact on the resistance in all tested specimens’ content of the plastic fibers, especially at (1.5%) fibers.

This research mainly focused on the properties of decorative white cement tiles which made from waste glass and white cement. The ratio of waste glass powder and white cement were studied at 10 : 90, 15 : 85, 20 : 80, 30 : 70, 40 : 60, 50 : 50, 60 : 40 and 70 : 30 by using water content at 30 %wt. All components were mixed and cast into the mould. Decorative white cement tiles were curing at 14, 21 and 28 days. In order to characterize physical and mechanical properties, all tiles were measured density, water absorption and compressive strength. According to the results, it can be obviously seen that density increased and water absorption decreased with increasing waste glass powder content. The highest compressive strength of around 36.5 MPa was found at 20 %wt of waste glass powder. However, compressive strength decreased with increasing waste glass powder over 20 %wt (waste glass powder 20: white cement 80). It was found that the lowest compressive strength of around 30.58 MPa was found at 70 %wt of waste glass powder. Curing time also affected properties as it was found that increasing curing time to 28 days resulted in increasing of density and compressive strength. In order to study how long does essential oil last on decorative white cement tiles, the orange essential oil at 1, 5 and 10 %wt were added into the white cement paste by using waste glass powder : white cement at 20 : 80 with 30 %wt of water. Decorative white cement tiles were smelled by 30 people every morning for 30 days and it can be found that 10 %wt of orange essential oil last longest on the decorative white cement tiles with 22 days.

Portland Cement Hydration

Glass is an amorphous material, which could be a good pozzolanic material and can be beneficial in compressive strength gain. However, if waste of glass powder has undesirable contaminations (aluminium, clay impurities, sulphates, etc.) it can negatively affect hydration process. In the research were used two types of waste glass (with and without harmful impurities). Waste glass shards were obtained from a local waste recycling plant and its properties were investigated in the Portland cement hydration process. Properties of waste glass were analysed by SEM, XRD test methods, pozzolanicity of glass powder was investigated by Chappelle test method. The hydration process of Portland cement was researched by the semi-adiabatic test method and XRD analysis. Properties of hardened cement paste was analysed by: density, flexural and compressive strength test methods The main aim of this research is to analyse waste glass, which after primary cleaning is not suitable for secondary reuse and investigate its suitability in cement-based systems.

To study the strength of cement mortar with different particle size of waste glass powder, grinding and screening the colorless waste glasses to 38-53,53-75,75-150,150-300,300-600μm, and as supplementary cement materials replacing the cement of cement mortar at 5,10,15,20,25,30%, respectively. Meanwhile divide the experiment into two parts:containing water reducer or not and add fly ash as comparison at the same time, measuring the flexural and compressive strength of cement mortar for 28 days. It is concluded that the flexural and compressive strength of cement mortar are decreased when mix with water reducer with maintaining the dosage of water;The optimum size and amount of waste glass powder in the cement mortar keep the same whether it is mixed water reducer or not; The flexural and compressive strength for 28days of the cement mortar reach the best value and differ with the baseline group very few whether it's mixed water reducer or not.
