Particle breakage in sand blasting due to impact on ductile materials
… such applications are done by several processes. Sand blasting is one of them, where a stream of sand particles is forcefully projected onto a surface, with compressed air or steam. These sand particles break up into very small pieces upon impact, which are inhaled by workers to cause silicosis. …

Development of icejet-based surface processing technology
… potential of water ice. Material removal by blasting with ice media such as particles, pellets and slugs was investigated. The ice media was accelerated by entrainment in a fluid stream (air, steam, liquid water, supercritical C0_2), impact of rotating blades, fluid expansion, etc. The …

The use of Lethabo field 2 PFA in pavement quality concrete
… Cape. The aggregates used were Cape Flats Dune sand and Malmesbury shale (hornfels). The dune sand typically has very little fines content, causing severe bleeding problems in normal concrete mixes. The crushed coarse aggregate was 13 mm and flaky in shape. Ordinary Portland cement (OPC) was …

Design and Validation of a Force Measurement System for the Analysis of Airfoil Lift and Drag Characteristics
… the surface of polystyrene airfoils using a sand blasting technique, which resulted in a dimpled surface. This idea originated from the design of a golf ball, as the dimples are known to delay flow separation which allows the ball to travel further. In relation to wing design, there has been …

Abrasive grit application for integrated weed and nitrogen management in organic vegetable cropping systems
Abrasive weed control, or weed blasting, uses sand-blasting technology to propel abrasive grits at weeds, physically destroying their emergent structures. This approach has been successfully tested for use in agronomic crops, though research is needed for horticultural cropping systems. This …

Abrasive Blasting Process Optimization: Enhancing Productivity, and Reducing Consumption and Solid/Hazardous Wastes
Abrasive blasting process optimization is aimed at establishing relationships between applied feed rates and resulting productivity and consumption rates. It is clear that the high costs of disposal of the multimedia wastes generated by the dry abrasive blasting processes are of increasing concern …

Environmental Performance of Copper Slag and Barshot as Abrasives
… the clean technologies for dry abrasive blasting and would help shipyards to optimize the productivity and minimize the emissions by choosing the best combinations reported in this study to their conditions appropriately. This project is a joint effort between the Gulf Coast Region …
