AN EXPERIMENTAL STUDY ON MODE-II FRACTURE OF CONCRETE MODIFIED WITH STYROFOAM AGGREGATES AND PENTA BLENDED CEMENT (POZZOLANIC MATERIALS AND NANA SiO2)

S. Ramesh Reddy, Dr. V. Bhaskar Desai

Abstract


With the increase in demand for construction materials, there is a strong need to utilize alternative materials for sustainable development and the concrete made from industrial wastes is known as “Green concrete”. Styrofoam used as packaging tool in food and manufacturing production equipments to absorb vibration during handling and transportation process. After this process, the Styrofoam used to protect the equipment normally disposed off as waste and recycling process is very costly. An attempt is made to replace 100% natural aggregate with modified Styrofoam pieces as light weight aggregate. An attempt is also made to replace 11% of cement with three numbers of pozzolanic materials i.e., Silica fume, Slag and fly ash in equal proportion and varying percentages of  Nano Silicon oxide at 0, .5, 1 and 1.5% on 11% of cement to study mode-II fracture properties along with corresponding compressive strength of modified concrete.
