MECHANICAL AND CHEMICAL PROPERTIES OF CEMENTITIOUS MATERIALS USING γ-2CaO.SiO₂ UNDER THE SEVERAL CONDITIONS IN ACCELERATED CARBONATION CURING

Abstract

 The experiments have been conducted in order to investigate the mechanical and chemical properties of mortar with three different binders under the several conditions in accelerated carbonation curing. As the results, the depth of carbonation varied among each mix proportion. It is proven that by increasing CO₂ density in the mortar having γ-2CaO.SiO₂, the CaCO₃ production will increase, which leads to the increase of filling ability in the pore of mortar. Furthermore, as a result from the calculation of Tritium permeation, it shows that the permeation decreases with an increase of CO₂ density.
