Crack Development and Grout-Block Interaction in Concrete Masonry Prisms
This paper presents the results obtained from an experimental study conducted on grouted masonry prisms. The study determined the interfacial interaction between the grout and concrete blocks, as well as the development of cracks leading to final failure when grouted prisms are loaded in compression. A total of two 4-course high grouted concrete masonry prisms were constructed. These prisms were constructed using the running bond pattern. One of the prisms was cut along its length (390 mm) and one was cut along its width (190 mm), hence, four cut prism specimens were tested. Experimental data was obtained using the innovative digital image correlation (DIC) technique and an accurate data acquisition system. In addition, linear variable displacement transducers (LDVTs) were also used for the validation of the DIC data. The DIC technique was used to effectively observe and track the crack growth and pattern of the concrete masonry prisms, as well as to observe the interaction between grout and concrete blocks. The results obtained from this study showed that DIC is a technique that can be used to determine these behaviours which have not been observable in the past.
