摘要

The present invention relates to a method of producing a cement mortar with a density of 1200-2000 kg/m3 with good stability in a fresh condition. According to the invention, this good stability in the mortar is achieved through an extremely fine-pored structure initiated by fine-particle material with certain fixed properties added to the fresh mortar. The invention also comprises a method, using said mortar as a binding agent, of producing a lightweight aggregate concrete with an aggregate content of 45-80 percent by volume and a density below 1400 kg/m3 where the aggregate material has a particle density of less than 1200 kg/m3 and the mortar entirely fills out the space between the aggregate particles.
