Quality Counts Make sure that your concrete producer purchases good quality aggregate as verified by regular aggregate test results in compliance with ASTM C 33 Standard Specifications for Concrete Aggregat A history of good performance of a local aggregate also provides an indication of how well the material performs in serviceLow Density Natural Aggregate Concrete Most low density aggregates are volcanic in origin and include pumice tuff scoria and cinders Diatomite is also something used as the aggregate component of lightweight concret The advantage to these types of aggregate is that they often do not require processing apart from crushing or screening
