Aggregate grades and quality parameters CSC Screeding

Apr 28, 2014Right from grading to the shape, texture and inertness of the aggregate material, there are several quality parameters that can influence the quality and cost of production of a screed. Grade Grading is the process of classifying aggregates into uniform lots based on particle size.

Aggregate in Concrete The Concrete Network

Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates. To produce good quality, durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete, with mix adjustments made, as needed.
