Properties of concrete incorporating nano-silica

Construction and Building Materials, 2012
Abstract This study investigated the effect of colloidal nano-silica on concrete incorporating single (ordinary cement) and binary (ordinary cement + Class F fly ash) binders. In addition to the mechanical properties, the experimental program included tests for adiabatic temperature, rapid chloride ion permeability, mercury intrusion porosimetry ...

Synthesis of nano silica particle from silica sand and characterization of nano silica based R134a refrigerant

Materials Today: Proceedings, 2021
Abstract This paper presents the synthesis and characterization of a mixture of different percentages of nano-silica with R134a as a refrigerant material. This work shows ways for enhancing the thermal performance of the vapor compression process and the effect of the suspended silica nanoparticle in the R134a refrigerant.
