摘要:
The present invention relates to a hydrophobic cement-based material composition comprising a bacterial biofilm, or at least one hydrophobicity-conveying component of a bacterial biofilm, an additive for a cement-based material composition comprising a bacterial biofilm or at least one hydrophobicity-conveying component of a bacterial biofilm and the use of such biofilm or component therefore for decreasing the wettability of a cement-based material.
摘要:
Light structural mortar compositions containing light loads, type II synthetic anhydrite and additives and methods for the production and use thereof are disclosed and described. Such compositions may be useful for application in ferro-cement constructive systems in order to provide thermal, acoustic and anti-seismic characteristics desirable for coating on interior and exterior walls and ceilings/roofs, as a substitution of cement-based mortar.
