Condition Survey of Assembled Concrete Blocks

these are an important part of the condition survey. Assembled concrete blocks are machine-made, prefabricated, modular units of pre-cast concrete, with light weight aggregate, made of low strength, hollow core block, bonded together using deformed steel bars grouted into preformed voids (i.e., hollow cores). Some blocks have

PDF Experimental Study on Hollow Block Masonry Walls Filled

Specimens for testing the compressive strength and shear strength of the hollow concrete blocks and masonry were made when the walls were built. At the same time, a number of mortar cube specimens for the masonry and the structural columns were cast and cured under the same conditions as the walls. All the mechanical properties of the hollow concrete blocks and masonry are shown in Table 1, Table 2, and Table 3, respectively.
