“…At above 900 o C, vitrification occurred leading to formation of glassy phase [17] which proportion is dependent on the proportion of WGP added. The glassy phase formed further covered the pores leading to reduction in porosity and enhanced compactment as confirmed in [18]. The consequent result is increased strength and hardness.…”

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.

Incorporating Liquid Crystal Display (LCD) Glass Waste as Supplementary Cementing Material (SCM) in Cement Mortars—Rationale Based on Hydration, Durability, and Pore Characteristics

This paper assesses the feasibility of using liquid crystal display (LCD) waste glass as a supplementary cementing material in cement mortars. Two different sizes of LCD waste glass powder (LGP) particles were used (5 µm and 12 µm) with two substitution levels with cement in mortar (10% and 20%). The resulting mortars were evaluated for strength, hydration, porosity and durability through various experimental techniques. It was found that LGP particles lead to appreciable strength gain at all ages in comparison with control mortar, especially significant strength gain of 18% was observed at 28-day. This is attributed to the greater gel-space ratio as corroborated by the experimental determination of porosity, which is found less for LGP-incorporated mortars as compared to control cement mortar. The smaller particle size of LGPs not only accelerates the pozzolanic reaction in alkaline cementitious matrix, but also fills the smaller pores, thus reducing porosity and contributing to strength gain. Increased hydration was also elucidated qualitatively by backscattered electron imaging. Due to the increased hydration in LGP-incorporated pastes and mortars, the durability (in terms of chloride ion permeability) has also been found improved. Thus, it is established that 10% (by weight) of cement can be replaced with 12 μm LGP, whereas 20% can be replaced with 5 μm LDP for improved strength and durability. Incorporating LCD waste in mortars and concretes as partial replacement of cement can not only help utilize this potentially hazardous waste, but also significantly reduce the associated carbon dioxide emissions, thus promoting sustainable development.

To prevent chemical erosion of concrete and improve chemical resistance, reinforced concrete flumes were manufactured, conforming to the Korean Industrial Standards (KS). Two different sizes of liquid crystal display (LCD) waste glass powder (LWGP) particles were used (i.e., 5 and 12 µm) with two substitution types with cement in concrete (i.e., 10% and 20%). Changes in compressive strength, pore structure, weight, volume, and strength of the concrete flumes after immersion in two sulfate solutions (i.e., Na2SO4 and MgSO4) for 84 and 182 days were measured for sulfate attack resistance. The applicability of the LWGP concrete flume with a 0.5 mm crack width was also evaluated based on the bending strength results. The LWGP5, which has a smaller particle size among LWGPs, filled the smaller pores, thereby reducing the porosity and contributing to the compressive strength gain. Higher volume and weight change ratios for all specimens immersed in MgSO4 solution were found than those immersed in Na2SO4 solution under identical conditions. Flexural loads of all the LWGP concrete flumes with 0.05 mm crack widths were greater than 48.5 kN, as required by the KS code; however, these flexural loads were lower than those of ordinary Portland cement. The applicability was also validated via a flexural test complying with KS.
