Lightweight Expanded Clay Aggregate

For the production of structural concrete with an oven-dry density of less than 1800 kg/m 3, a German manufacturer has produced from about the early 1970s a spherical expanded shale aggregate (''Liapor'') in a range of particle densities from 0.80 to 1.70 Mg/m 3. This represents one of the most significant advances in lightweight aggregate ...
