Horizon Infradesigns Pvt. Ltd. in its endeavor to share its experience has come up with economical solutions of affordable housing projects. HIDPL found that hollow concrete blocks in place of clay or solid fly ash bricks will provide better performance & economical solution in low rise (G+2, G+3) buildings. Use of hollow blocks provides better strength with a 25% lighter structure. In this construction system, structurally, each wall and slab behaves as a shear wall and a diaphragm respectively, reducing the vulnerability of disastrous damage to the structure/building, during the natural hazards. Due to the uniform distribution of reinforcement in both vertical and horizontal directions, through each masonry element, increased tensile resistance and ductile behavior of elements could be achieved. Hence, this construction system can safely resist lateral or cyclic loading, when compared to other conventional masonry construction systems. This construction system has also been proved to offer better resistance under dynamic loading, when compared to other conventional systems of construction. Steel consumption has been reduced by 15-20% as compared to R.C. Framed structure in Zone-2 & Zone-3 regions.
