Abstract
The most effective use of masonry construction is seen in load bearing structures where in it performs a variety of functions, namely, supporting loads, subdividing space, providing thermal, as well as fire and weather protection. Today load bearing masonry structures offer a competitive and an economical building systems compared with the different skeleton type structures especially in new cities, which have enough areas for buildings. On the other hand several construction companies have adopted the production of the pre-cast block masonry and employing it widely in housing constructions. The research intends to study the possibility of producing lightweight hollow block made with ferrocement. The effect of Fermoklite, polystyrene (Eps) and lime on the weight of hollow block were investigated. Also, the durability of hollow block units was investigated. Also, the behaviour of ferrocement wall and column made with the lightweight hollow block were investigated. Three phases were studied to carry out the aims of the research. In the first phase, twelve different mixes were cast to determine the mechanical and physical properties of these mixes. In the second phase, hollow blocks made with ferrocement with 200 × 200 × 400 mm were cast with the best mix in weight and strength to investigate its properties and compared it with normal hollow blocks in the Egyptian market. Compressive strength, tensile flexure strength and modulus of elasticity were investigated to get the mechanical properties of the trial mixes and hollow block mixes. The density of mixes and hollow blocks were investigated. In the third phase, walls and columns specimens made with the ferrocement lightweight hollow block with dimensions 200×420×620 mm and 200×820×620 mm, respectively were manufactured to investigate its mechanical properties with some variables such as the vertical and horizontal connection and the reinforcement plastering. The results showed that the density of the polystyrene lightweight mortar (M4) was 1700kg/m3. A compression with different codes of hollow block was investigated. The Lightweight hollow block units made with ferrocement of batch M4 comply with the EOS 2005/42 strength criteria for load bearing applications. For columns specimens (WSXL2) from group (SX) achieved the maximum load capacity by 700 kN and (WFXT from group (FX) & WFV from group (FV)) achieved the minimum load capacity by 450 kN. For walls specimens; (2WSXL2 & 2WSXL3) achieved the maximum load capacity by 800 KN with increment by 78% compared to the control specimen and control specimen (2WSEL1) achieved the minimum load capacity by 450 kN. Good agreement was reached by ANSYS 14.5 as a finite element package compared to experimental results.
