DEVELOPMENT AND APPLICATION OF LIGHTWEIGHT CEMENT-BASED COMPOSITES

Abstract eng:
The purpose of this study is to suggest the material design method of lightweight mortar that reduces the mass of building components and provides them with better insulation. To achieve this, we applied a number of special lightweight aggregates and applied the packing density model, porous mortar, and a combination of both methods. A series of experiments were carried out in order to investigate the mechanical properties and examine the thermal conductivity of mortar. The study identified that the adopted material design methods were effective in reducing the density of mortar and in obtaining sufficient insulation. Furthermore, compressive strength sufficient for structural purposes was also achieved in certain types of mortar. Finally, by combining the packing density model and porous mortar, lightweight insulation blocks were developed for achieving not only sufficient bearing capacity but also high insulation performance.
