Strength and Durability Investigation Cement Mortar Partially Replaced with Nanoclay and Carbon Nano Fibers

Abstract

Nanotechnology (nanotech) is the manipulation of matter on an atomic molecular and supramolecular scale . The introduction of nanotechnology represent a revolution that is responsible for the development of high performance and long lasting products and processes within on ideal context of sustainable development. It will affect almost every aspect of one’s life. In comparison to other technologies, nanotechnology is mush less well defined and well structured. Nanotechnology is on emerging field by science related to the understanding & control of matter at the nanoscale i.e.dimension between approx 1 and 100 nm. Nanotechnology encompasses nanoscale science, engineering and technology that involve imaging, measuring, modeling and manipulating matter at this length scale. ‘Nano’ means 1 billionth or 9 10 .Use of nanoclay in this field proves to be a great enrichment to the cement mortar to improve its properties. Nanoclay helps to make mortar a multipurpose smart functional material. The use of nanoclay is used to increase the strength and durability of cementitious composites as well as for pollution reduction, Production of thermal insulation materials with a performance ten times commercial current options, Production of cheap corrosion free steel.Production of nanosensors and materials with sensing ability and self- repairing ability The basic objective of the study is to to investigates the optimized level of reinforcing cement mortar with nano material in small varying proportions &to investigate the effect of carbon nano fiber replacement level on compressive strength of mortar by conducting compressive strength and flexural test. To investigate the effect of carbon nano fiber replacement level on durability by conducting water absorption test and acid resistance test.To investigate the effect of carbon nano fiber replacement level against sulphuric acid and nitric acid attack.
