Behavior of the Dry Bed Joint in the Mortarless Interlocking Masonry System: an Overview

In the past few decades, the concept of interlocking mortarless masonry unit has been widely increased in the field of civil engineering applications and construction practices due to its field productivity, efficiency and less skilled workers needed in the production and implementation [1]. One simple thing that absolutely contrasts interlocking bricks from conventional bricks is the mortar between bricks layers where mortar is not required for the construction of interlocking bricks. Due to that characteristic, the construction of masonry walls is faster and needs even unskilled workers as the bricks are arranged dry and interlock each other by the protrusions [2]. An assortment of interlocking bricks have been manufactured and produced during the last few years, varying in the composition of material, shape, size, strengths required, and usage needed, including Sparlock, Meccano, Sparfil, Haener, and Hydraform block system [3].
