Ferrocement blocks or masonryblocks are a type of thin concrete made of cement sand matrix with closely spaced relatively small diameter wire meshes, with or without steel bars of small diameters called skeletal steel. Masonry is a well proven building material possessing excellent properties in terms of appearance, durability and cost in comparison with alternatives. However, the quality of the masonry in a building depends on the materials used, and hence all masonry materials must conform to certain minimum standards. The basic components of masonry are block, and mortar, the latter being in itself a composite of cement, lime, sand and sometimes of other constituents. Such blocks in addition to wire mesh were investigated experimentally under compressive strength. A total of nineblocks were constructed and tested under compressive load. The dimensions of hollow blocks were (400x200x200) mm. The main parameters considered in the present investigation were the number of wire mesh layers (2), and type of constituent materials (mix proportions). The behavior of block models under compressive loading was observed by reading the loads and observing the initial and crack patterns and mode of failure. It is concluded that the compressivestrength of ferrocement blocks having (2 wire meshes) isconsiderably higher than that of mortarblockswithout mesh layers only by about (73.4 %). The behavior is less significantly affected when wire mesh are added to ferrocement blocks with (2 mesh layers), the increase was about (57%) with concrete blocks, and finally the presence of wire mesh reinforcement in the blocks decreases the water absorption compared with the corresponding concrete blocks.
