BENDING CAPACITY OF DRY STACKED LIGHTWEIGHT CONCRETE BLOCK MASONRY

Summary, in English

Dry stacked light weight concrete block masonry is increasingly used due to its superior productivity compared to standard block masonry. Low bending capacity parallel to the bed joints is however a major drawback. This paper presents the results of an experimental study which has been carried out to improve the bending capacity of dry stacked lightweight concrete block masonry. The effects of following measures have been studied: 1) the blocks have been provided with additional holes forming continuous vertical canals and grouted with concrete; 2) both faces of the dry stacked block masonry have been reinforced with a steel wire mesh embedded in render. The bending capacity has been determined in four-point bending tests. Compared to standard dry stacked masonry the bending capacity increased by: 1) 20 % when the additional, continuous vertical canals were filled with concrete grout; 2)more than five times when steel wire mesh embedded in render was used.
