Concrete is a composite material consisting of cement, water and aggregates. Concrete is sufficiently strong in compression but weak in tension. Concrete is widely used as construction material worldwide. It consumes most of the natural aggregates. Due to high speed in development of infrastructure, the natural aggregates are being fall short off. To ensure long life and sustainability of concrete construction materials, it is the need of the hour to preserve the natural aggregates. One such attempt is to utilize the waste products from industry in the manufacture of concrete. The waste products are fly ash, silica fume, rice-husk, polypropylene, marble powder, foundry sand etc. The necessity of utilization of waste materials as a component of concrete composite can be in the form of either replacement of ordinary Portland cement by a waste having similar cementing properties and fine aggregate having similar composition and waste materials can also be added to concrete composites so as to improve the properties of concrete composite. This will help in management of preservation of natural aggregates, saving in energy for production of cement, utilization of waste which is a problem for thermal power plants as well as industries, saving in greenhouse gas emission, economical construction material, green concrete composite and many more factors.Keywords

Precast cement concrete paver blocks are used for road surfacing. The performance of road surfacing is better than asphalt and rigid concrete pavements. These are made as small elements from plain cement concrete with zero slumps. An attempt has been made to replace OPC by fly ash for manufacture of paver blocks of M35 grade with thickness 60mm and 80mm. Fly ash is a byproduct of thermal power plant which is a waste material. OPC has been replaced by fly ash in varying proportions of 0%, 20%, 30% and 40%. This paper presents the study of compressive strength and flexural strength of paver blocks and it was found that 30% of OPC replacement by fly ash is optimum.Keywords
