Effects of Waste Glass Powder as Pozzolanic Cement Supplementary Material for Structural Elements

The ever-growing global production of glass generates high waste percentages, the vast majority of which does not get recycled hence increasing the concern on its environmental impact. Studies on the pozzolanic properties of glass powder emerged as a solution to the abundance of waste glass powder available and its insufficient recycling. The aim of this study is to investigate the influence 10% ,15% and 20% of waste soda-lime glass powder as partial cement replacement; fresh concrete tests were carried out, as well as compression strength tests at 28 days on grade 280 kg/cm2 concrete produced with pozzolanic cement. Tests results show an insignificant reduction of slump on the concrete mixes, an increase of air content and a decrease in density and compressive strength resistance with increasing glass powder substitution.

Influence on flexural properties of glass powder in self compacting concrete

Abstract Self-compacting concrete is a high performance concrete that can flow under its own weight to completely fill the form work and self-consolidates without any mechanical vibration. This work summarizes the utilization of glass powder addition on the concrete as to relieve the provision, affordability, strength and contamination issues. In this paper the experimental study were done on the M20 grade of SCC specimens were casted, arranged with addition of four different proportions weight (0.3%, 0.6%, 0.9%, and 1.2%) of glasspowder with water cement ratio of 0.45. Prism-100*100*500 mm and cylinder-150*300 mm were prepared for testing after 28 days natural process in water served as the control. Slump cone, L-Box, U-Box, V-Funnel and J-Ring tests were performed to determine the properties of fresh concrete on both r-sand and m-sand. The fresh concrete tests are done for self-compacting concrete to know the flow and workability of the concrete. The properties of hardened concrete tests on both river sand and manufacturing sand can also experimented by conducting the flexural strength and split tensile strength test. The tests are conducted after 28 days age of curing. The tests results show the workability and characteristics of concrete.

The effect of cullet grinding in impact-repulsion mills on the properties of glass powders

The change in the structural and energy properties of the glass powders resulting from rapid grinding of the cullet in an impact-repulsion mill is considered. The increase in crystallization capacity of the glass powders attributed to this effect is discussed. This effect must be taken into account in production of the foam glass, filters, membranes, and partitions.
