"Development of masonry Blocks Using Bituminous Emulsions" is basically stressing about research on new material to be applied in construction technology. As widely known, concrete is brittle in nature and are prone to fragmentation. Same problem applied to glass walls. Fragmentation will cause the material to break into chips and predominantly lose its strength. Apart from that, development of this new material is also initiated due to the increase in terrorist attacks to high rise building causing majorcasualties as well as injuries to the occupants as well as pedestrians. In order to fit the requirement of this research, wax emulsionis experimented to understand its behavior in terms of strength, flexural and durability. The material used is Burke Wax Emulsion White (Type II), For comparison purposes, conventional bitumen mix is also tested. The mix proportion of the bituminous material is done following the concrete proportion. Same testing method in designing bituminous mix for flexible pavement applies to this research. The specimens will be tested using Marshall Stability testing equipment which will give the optimum binder content value, Beam Fatigue equipment which will give its flexural stiffness and deflection and durability test which will give its resistance against temperature effects. Wax emulsions produced materials with high compressive strength and durability characteristic but at low deformation rate. However, it fails instinctively under dynamics loading due to its stiffness and inflexibility to absorb loadings. Due to this factor, fiber addition is necessary to increase its flexibleness and tensile strength. Thismaterial can be used for construction of non-load bearing partition wall, slabs or floors which experience static loadings alone. Findings from this research will open a new era for building construction technology. A more cost effective material to concrete and brick wall structures is found. Coatings of surfacesfrom the wax coupled with its hydrophobic nature, will sufficiently act as a moisture barrier to prevent conduction and unwanted penetration and interaction of various liqiuds in masonry blocks.
