Modern silicates product reach compressive strength up to 35 MPa. Further scientific research should improve other properties. In the article they presented improvement possibility, of sound absorbing and soundproof property of calcareous and sandy products. It allows, to lower the thickness with conservation of required strength characteristics.
Silicate product characterize „theory of pulp” with high endurance on grip. It in aim of improvement of their propriety of acoustic isolation, was one should according to raise their pulp. This decrease the dimensions of silicate product causes and decrease on energy demand near their production simultaneously.
