The Growth in the Electronics sector has been rapid and this rapid growth is due to continuous upgradation of technology and introduction of new technologies to the market. This has led to one of the fastest growing solid waste in the world, simply called as E-waste. India is the 5th highest e-waste producer in the world. The rapid increase in the construction activity in India, has resulted in huge demand for the aggregates to be used in the concrete. This has led to depletion of natural resources and adverse changes in the environment. This rapid development in the infrastructure sector has led to shortage of natural sand. This paper outlines the experimental work carried for utilisation of e-waste as a partial replacement for the fine aggregates. Strength tests and durability tests are conducted on hardened concrete. Results show that the partial use of E-waste as fine aggregates results in much higher workable and less dense concrete. This study gives an Economic, environment friendly and efficient disposal method for E-waste to be used as a partial replacement to the fine aggregates in concrete.

The research in construction industry nowadays is mainly focusing on the basic science of cement materials at nano level. The research is also continuing to improve the durability and sustainability of concrete and realized significant increase in strength of material by incorporating nanoparticles. The review paper summarises the effect of various nanoparticles addition on the strength material. It provides the current development of application of nano-materials in mortar and concrete. Nano material can assist in intensifying the use of resources and get the required properties by reducing the use of resources. This review paper also addresses the current development regarding use of nanomaterial in construction industry. The paper first presents general information, then focuses on the most effective nano additives such as nano silica, nano-titania dioxide, iron oxides, chromium oxide, nanoclay are summarized. Along with benefits, some health risks are also associated with the use of nanotechnology. The risks are can be remedied so that the nano building products could be fully exploited for the benefits of mankind.
