Study of effect of al2o3 nanoparticles on the compressive strength and workability of blended concrete

Author:

Agarkar, S. V. and Joshi, M. M.

Subject Area:

Life Sciences

Abstract:

The compression test was carried out in accordance with IS 456-2000; on nano Al2O3 blended concrete & plain concrete. Al2O3 nanoparticles with the average diameter of 15 nm were used with four different contents of 0. 5%, 1.0%, 1.5% and 2.0% by weight. The tests were carried out on M20 grade of plain cement concrete and nano Al2O3 Blended concrete. The results revealed that the compressive strength of some of the samples is improved. The workability of fresh concrete was decreased by increasing the content of Al2O3 nanoparticles.It is concluded that partial replacement of cement with nanophase Al2O3 particles improves the compressive strength of concrete but decreases its workability.
