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.

Shock Resistance

Effects of elevated temperature on thermo-mechanical properties of fired ceramic products reinforced with waste glass powder (WGP) were reported. Samples were produced by the addition of WGP to clay in varied amount and oven dried samples were fired in an electric furnace which was operated 1200 oC. Compressive and flexural strength were examined at room temperature and at elevated temperatures of 100, 300, 500, 700, and 900 oC. Results showed that, compressive strength and flexural strength reduced at elevated temperatures. Thermal conductivity, diffusivity, and emissivity were higher with increasing WGP content, while thermal expansivity and specific heat capacity were lower as percentage WGP increased in the samples. Results on thermal shock resistance showed that WGP reduced shock resistance in the samples, while the cooling rate increased with the percentage addition of WGP. Impact resistance was noted to decrease in samples when fast cooled from high temperature as the rapid cooling rate was observed to increase with WGP addition in samples. It was concluded that for fired clay products incorporated with WGP, the operating temperature should not exceed 700 oC. Also, in an environment whereby cooling is done by air or/and water, an operating temperature of ≤ 300 oC was recommended.

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.
