FILLER WITH LIGHTWEIGHT AGGREGATES

摘要

The invention relates to a dry construction material mixture (bulk density < 1.3g/cm3; particle size 10-500 µm), suitable for producing filler and containing at least one lightweight aggregate in addition to hydraulic and/or non-hydraulic binding agents and mineral aggregates. The filler obtained by adding water to said dry construction material mixture is characterised by a significantly reduced fresh apparent density (1-1.7g/cm3), increased pressure resistance (>30-40 Newton/mm2), and a better coverage rate during the application thereof.
