STUDY ON MECHANICAL PROPERTIES OF CONCRETE WITH SILICA FUME AND SYNTHETIC FIBRES

Abstract

The majority of the world's buildings, bridges, and other structures are constructed with concrete. To complete this infrastructural development, a massive amount of concrete is needed. There has been a push tos find alternatives to cement in developing nations due to concerns about the material's impact on the environment, the energy required to produce it, and the rapid depletion of natural resources. It is well-known that cement is one of the most costly components of concrete. This research aims to examine the effects of adding rice husk ash and silica to regular Portland cement on the concrete's strength characteristics. "silica fume Fibre reinforced concrete" is the name given to the composite matrix that is created by mixing aggregates, fibres, cement, and rice husk ash. Cement matrices made of rice husk ash include fibres that serve as crackarresters, limiting the expansion of microcracks when subjected to stress. In place of cement, silica fume and synthetic fibres have been the subjects of experimental research into their effects. Under typical curing conditions, the compressive strength was achieved after3,7, and 28 days.
