Investigations on the preparation and mechanical properties of the nano-alumina reinforced cement composite
TL;DR: In this paper, the effect of nano-alumina on the elastic modulus and compressive strength of cement composite, cylindrical specimens ( Φ 20 × 40 mm) with different volume fractions of nano alumina at different curing days (3 days, 7 days, 28 days).
Influence of Al 2 O 3 nanoparticles on the compressive strength and workability of blended concrete
TL;DR: In this article, the compressive strength and workability of concret e by partial replacement of cement with nano-phase Al 2O3 particles were investigated, and it was concluded that partial replac ement of concrete with nanophase Al 2 O3 particles improves the compressed strength of concrete but decreases its workability.
