Load Capacity Of Masonry Made Of Flat-bricks And Cover Up Thin Layer Mortars

Summary

In order to reduce construction costs, large-sized flat masonry units with enhanced thermal insulation are nowadays laid and bonded using thin layer mortars.  Costs are saved as a result of the smaller amount of mortar required and the  shorter building times.  The method used to spread the mortar is outlined.  It is pointed out that the technique may sometimes result in uncovered holes in the units, considerably reducing sound protection.  Novel cover up thin  layer mortars have been developed which provide a high degree of cohesion and are better at covering the holes.  By  using these novel thin layer mortars, sound protection as well as thermal insulation can be improved, convection is reduced, and the load capacity increased.  An attempt was made to determine the load capacity of flat-brick masonry laid using the new thin layer mortars in order to contribute  to establishing strength values, e.g., for revision of German standard DIN 1053-1.  Moreover, any change in thermal  insulation due to the use of these new mortars should become  apparent.  Abstract only.
