Exposed Aggregate. The term Exposed Aggregate is exactly that. We expose the stone that we make the concrete from. The result is a very hard-wearing surface (after all, stone is generally harder than concrete). To create different finishes, we use a variety of aggregates, including quartz, granites, basalts and marble, to name a few.

Cryogenic grinding produces particles of rubber with a finer surface than produced by ambient grinding. The granules of grinded rubber produced by ambient grinding are soft ( Kim et al., 2018 ). Like plastic waste, rubber waste, due to its low density, is also appropriate for use as lightweight aggregate.

Use a diamond end grinding machine as necessary to square off and flatten each of the sample ends to meet the tolerances of ASTM C39 (Ref. 7.3). Diamond end grinding of the sample ends may be completed well in advance (e.g. upon demolding) of compression testing. Information about grinding cylinder and core ends

As the aggregate is transported by a conveyor belt, vibration and motion of the belt causes the fine particles to settle to the bottom of the material stream, whereas coarse particles remain at the top. These coarse particles have a higher velocity at the end of the conveyor, and are thrown a greater distance to the stockpile.

Concrete with coarse aggregate in the 3D concrete (3DCP) has broad prospects for high strength, low cost and shrinkage. In this study, an extrusion-based 3D printer was designed and utilized to print concrete with the largest aggregate size of 20 mm. Printable concrete with coarse aggregate was designed by different volume ratios of cement to …

The aim of this article is to present possibilities of producing aggregates with an increased content of regular particles in some well-known examples, as well as to present previously unused methods of aggregate production. Traditional aggregate production systems require the use of three or four grinding stages (depending on the particle size of the feed), …
