Abstract: This paper deals with the development of lightweight concrete. This also shows the importance of water/cement ratio as in first type of concrete it produce lightweight structural concrete with the unit weight varying from 1200 to 2000 kg/m³.. The isomer of all the phenyl groups on same side called polystyrene. Now a day’s number of researches have been done on lightweight concrete but in this research we have tried to make a concrete having possible lesser density and higher compressive strength. We have taken the following proportions , 30 % CM and 70 % EPS 40 % CM and 60 % EPS 50 % CM and 50 % EPS The size of the mould we adopted is 15 X 15 X 15 cm . hence the volume of the cube is 3.375 cm^3 . The plasticizer we used is sulphonate naphthalene formaldehyde. The plasticizer amount is 1.5% on volume of the cement mortar . The main aim of our project is to make a less air voids and densed concrete .
