CONCRETE BLOCK MASONRY, Introduction These are the concrete blocks either hollow or sol A hollow unit is that unit which has core void area greater than 25% of the gross area They may be used for both load bearing as well as non load bearing wallsMix designs for concrete block, CMU Cement binds aggregate par-ticles and partially fills spaces be-tween them 5a Choose the cement-to-aggre-gate ratio that will achieve the nec-essary CMU properties with aggre-gates being used in the mix Below are ranges of cement-to-aggregate ratios that can be used for various Figure 1 Aggregate gradation for concrete masonry units ,(PDF) Experimental Research of Hollow Concrete Block ,, The article discusses the results of experimental investigation of highly hollow concrete block masonry and concrete infill block masonry behaviour under compressionConcrete Block Construction, Walls, fences, and partitions constructed of concrete masonry screen block offer privacy and provide partial sun and wind control Since most decorative block is laid up using continuous vertical mortar joints used in standard block and brick work, your main concern when planning and constructing a screen wall project will be stability and ,IS 2572 (2005): Construction of hollow and solid concrete ,, 691 Mortar shall be composed of cement, lime and sand, unless otherwise specified All lime other than dry hydrated lime shall be fully slaked in accordance with 1S 1635 692 Hollow concrete blocks shall be embedded with a mortar which is relatively weaker than the mix used for making blocks in order to avoid the formation of cracks.
