Different particle size range of waste glass powder amount to replace part of the cement made to mortar specimens, which were soaked in 5% sodium sulfate solution and water after standard curing .Then determining its mechanics properties in various ages, observing and analysis of the micro structure of the section of the specimens by SEM, exploring the ability of mortar specimens made in different size and dosage of waste glass resist to sulfate. The results indicate: Along with the rising of the size and content of glass powder. The performance of mortar specimens resisting to sulfate were on the decline. When replacement amount was 10%, all kinds of particle size of waste glass mortar specimens are better than that of ordinary Portland cement on mechanical properties, When the glass powder size is less than 53μm, all kinds of mortar specimens with high content of waste glass are better than that of ordinary Portland cement on mechanical properties.

In this study, it investigated the micropore changes by aging of LCD waste glass powder and investigated the effects of particle size and replacement ratio on sulfate erosion. Also, the comparison of the compressive strength with that of OPC concrete was carried out to evaluate the sulfate resistance of the LCD waste glass mixed concrete. As a result, resistance to sodium sulfate is better than magnesium sulfate.

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.

Binder Ratio

The transport characteristics of waste glass powder incorporated self-compacting concrete (SCC) for a number of different durability indicators are reported in this paper. SCC mixes were cast at a water to binder ratio of 0.4 using glass powders with a mean particle size of 10, 20 and 40 µm and at cement replacement levels of 20, 30 and 40%. The oxygen permeability, electrical resistivity, porosity and chloride diffusivity were measured at different ages from 3 to 545 days of curing. The amount and particle size of the incorporated waste glass powder was found to influence the durability properties of SCC. The glass incorporated SCC mixes showed similar or better durability characteristics compared to general purpose (GP) and fly ash mixes at similar cement replacement level. A significant improvement in the transport properties of the glass SCC mixes was observed beyond 90 days.
