The Cause Detection and Analysis of the Surface Cracks on ETIRS
The cause detection and analysis have been made over the surface cracks of external thermal insulating rendering systems made of mortar with bonding powder and using expanded polystyrene granule as aggregate (ETIRS) by means of integrating the basic concept of the cracks and actual project practices, on the basis of structure design, materials performances and construction. The result shows that the major causes for surface cracks, the hazardous ones are caused by poor construction quality. In order to guarantee the quality of external thermal insulation wall, the structure design of the said thermal insulation system shall be underlined and building quality on the key parts, stressed.
