This thesis reports on the structural design and analysis of masonry structures using thin joint mortar. Thin layer mortar has been developed to compliment some of the disadvantages associated with conventional masonry techniques. It is polymer-modified cement based mortar, which when mixed with water produces a smooth cohesively flowing non-Newtonian adhesive. An extensive structural testing and evaluation research program based on British and European standards was carried out to investigate the engineering properties and performance of thin layer masonry formed using three clay, one dense concrete and one Aircrete brick, two concrete blocks and calcium silicate units under different types of loading. The study also aims to investigate the feasibility of new uses for thin joint masonry, and perform comparisons between the experimental results and the British and European standards. Test results show that significant gains to the tensile flexural strength of masonry can be achieved when thin layer mortar technology in conjunction with solid dense concrete blocks and bricks and with clay bricks to a lesser extent. No enhancement with calcium silicate units was observed. This research compares the flexural test results to the values suggested in the codes and with concrete, Aircrete and clay units enhanced values are obtained but with calcium silicate units no significant increase in flexural strength is achieved. These test results were then used to predict wall strengths and again with thin layer mortar, panel strength increased. The research indicates changes should be made to the relevant codes. Further, this study will provide confidence to both designers and contractors to use and further develop the application of thin layer mortars in building.
