The demand of house for residential purpose increases with increasing population, Mass housing targets cannot be achieved by conventional burnt clay brick Due to its high production cost, environmental polluting production process and raw material obtained from natural resources and due to all that reason this conventional burnt clay brick become un-sustainable. To develop a sustainable choice we have to develop a material whose production doesn’t causes pollution and utilizes waste material. the following material was identified as waste but works perfectly as raw material for masonry blocks are:- 1. Geopolymer binder 2. Expanded polystyrene 3. PET bottles The geopolymer is one which is the most sustainable replacement for cement because production of ordinary Portland cement releases a very high amount of carbon di oxide, during production more than fifty percent of carbon di oxide releases in calcination of lime out of total carbon di oxide release during whole production process, the amount of carbon di oxide released is approximately equal to amount of cement produce. Expanded Polystyrene (EPS) is a lightweight, rigid cellular plastic that is made from the polymerization of styrene monomer while styrene is a liquid hydrocarbon that is commercially manufactured from petroleum. The expanded polystyrene is a single use plastic it does not have any scrap value therefore after use it is dumped in a dump yard or disposed in land fill. It is considered as possible human carcinogenic by International Agency for Research on Cancer and it also have ability to soak chemicals. Beverage bottles made from polyethylene terephthalate (P.E.T.) is also a single use plastic producing trash and possible human carcinogenic. It is not decomposable it exists in environment for more than 500 years.it makes land barren it pollutes ocean and disturbs marine ecosystem. In this research work the light weight masonry blocks was developed using all materials discussed above and using geopolymer as base binding material and crushed expanded polystyrene as filler and fibers of p.e.t. bottle to provide toughness. Due to expanded polystyrene filled matrix of geopolymer the product gains sound and thermal insulating properties, the product becomes light weight due to which its transportation cost reduces, imposed load on structure reduces which leads to cost reduction, the effect of lateral load can also reduce, it reduces trash, and does not causes pollution
