摘要

Lightweight concrete comprises a porous binder matrix (2) based on a binder and particles (1) of a finely ground mineral open pore light aggregate to introduce pores into the matrix. Preferred Features: The light aggregate is made from perlite and has a grain size of not more than 1 mm. The binder is cement, lime or a calcium silicate hydrate composition.
