Glass Beads vs. Crushed Glass April 5, 2019. Glass beads and crushed glass are both effective abrasives to produce a desired finish on a part. Glass beads are commonly used in a blast cabinet or reclaimable type of blast operation. They impart a consistently bright matte finish on aluminum and steel substrates.

Short answer: YES Finely-crushed glass is basically a pure form of sand. When you grind down crushed glass to a fine powder, the difference between glass and sand is negligible at best; natural sand is made of quartz crystals of silicon dioxide and glass is the non-crystalline, amorphous form of silicon dioxide.

Expanding glass is a process where crushed glass cullet is upcycled on the particle size level and re-formed into spherical-aerated-granules that don’t contribute toward ASR. The material is stable and inert with a chemical composition containing around 71% silicon dioxide (SiO2).

Very finely powdered Crystalline Silica sand is used to manufacture glass, which means that glass making is a hazardous process. However, when the Crystalline Silica crystals are melted, they change form to Amorphous Silica (Non-Crystalline Silica). When this melted mass of Amorphous Silica is rapidly cooled, glass is formed.

Alkali-silica reaction must be considered When using glass aggregate outdoors, or anywhere else that the concrete will be exposed to moisture, beware of the dreaded alkali-silica reaction, an unhappy phenomenon in which the silica in glass and the alkali in cement create a gel that swells in the presence of moisture.

Glass cullet from the crushing of post-consumer glass is readily available in urban areas. It can be added in small quantities (probably < 20%) into many mixes, but its smooth surface means that it is difficult to achieve a good bond with the surface. Glass dust is a hazardous irritant, so appropriate health and safety precautions must be taken (see Section 7.4.3).

Recycled glass is a mixture of different coloured glass particles with debris. It is the result of crushing the waste glass collected from residential and industrial areas. Construction and demolition (C&D) materials such as concrete, excavation stone (basalt) and brick make up a significant proportion of the waste materials present in landfills in Australia.
