Nano-boosted concrete: revolutionizing strength and durability for modern construction

ABSTRACT Nanotechnology is being investigated as a potential solution to enhance the strength and durability of high-strength concrete (HSC). The aim of this paper is to provide high-strength concrete, silica fume has used to provide matrix densification of concrete with high silica content and pozzolanic reactivity, and metakaolin which is well known for its high purity and fine particle sizes. Totally 13 mixes were prepared one with control mix and 12 mixes with the variation of metakaolin and silica upto 20% replacement individually with the increment of 5% from 5% to 20% in OPC. The results show that silica fume and metakaolin used in combination has been significantly effective not only in increasing the engineering properties of HSCs but also in significantly increasing the resistance to environmental damage. The findings suggest that using these nanomaterials includes in concrete mixes, which can lead to more flexible industries underlining the potential that could revolutionize concrete by providing a way to manufacturing better building materials that last longer and reduce maintenance costs.
