Abstract Glass lapping residues (RLV) are fine tailings from the processing of glass for civil construction, commonly non-recyclable. The present study analyzed the use of these residues in Portland cement mortar composition, partially replacing the conventional aggregate, aiming at better compaction. Percentages of residues were adopted at 0% (reference), 5%, 10% and 20% by mass, replacing the fine conventional aggregate (sand). The binder used was Portland cement CP IV-32. The RLV and fine aggregate were submitted to physical tests, through grain size analysis, grain shape and specific mass; RLV and cement, in turn, submitted to chemical analysis by X-ray spectrometry, to identify the compounds. To evaluate the compressive strength and compaction analysis of the composite in the hardened state, cylindrical specimens 50x100 mm were produced. ANOVA (Analisys of Variance) and Coefficient of Variation showed that the RLV added in 5% resulted in lower voids indexes and moisture absorption than the conventional one. The tests also showed best mechanical performance on compression analisys (30,2 MPa) for 5% of residues in the composite, surpassing the conventional one.

AbstractThe beneficiation plate process by soda-lime glass lapping in the glass industry generates, an untapped residue (waste). The waste of this material is sent to landfills, causing impact on the environment. This work aimed to characterize and evaluate the waste of soda-lime glass (GP) lapping. After its acquisition, the GP was processed by grinding and sieving and further characterized by the chemical/mineralogical analysis (XRF, EDS and XRD), SEM morphology, particle size by laser diffraction, thermogravimetric analyses (TGA and DSC) and thermophysical analyses. It was observed that the GP particles are irregular and micrometric with the predominant presence of Na, Si and Ca elements characteristic of amorphous soda-lime glass. The assessment of the chemical/mineralogical, morphological, thermophysical and thermal gravimetric characteristics of GP suggest its reuse as reinforcing fillers or filler in composite materials to obtain thermal insulation.

This paper shows the removal rate and lifetime data of glass lapping process using 3M TrizactTM Diamond Tile Abrasive Pads. 3M TrizactTM Diamond Tile Abrasive Pads is a structured fixed abrasive grinding technology developed by 3M Company, it consists of a polymeric binder and diamond composite that is used with a water-based coolant. It can be applied in both single and double side grinding applications. Grinding results of 4S-4 micron grade of TrizactTM Diamond Tile abrasive pads on Corning GorillaTM glass will be presented.
