Abstract EN
The significance of concrete durability increases since RC (Reinforced Concrete) structures undergo degradation due to aggressive environmental conditions, which affects structural safety and serviceability.
Steel corrosion is the major cause for the unexpected failure of RC structures.
The main cause for the corrosion initiation is the ingress of chloride ions prevailing in the environment.
Hence quantitative evaluation of chloride diffusion becomes very important to obtain a chloride diffusion coefficient and resistance to chloride ion intrusion.
In the present investigation, 15 mix proportions with 3 water-to-binder ratios (0.37, 0.42, and 0.47) and 3 replacement ratios (0, 30, and 50%) were prepared for HPC (high-performance concrete) with fly-ash and ground granulated blast furnace slag.
Chloride diffusion coefficient was measured under nonstationary condition.
In order to evaluate the microstructure characteristics, porosity through MIP was also measured.
The results of compressive strength, chloride diffusion, and porosity are compared with electrical charges.
This paper deals with the results of the concrete samples exposed for only 2 months, but it is a part of the total test plan for 100 years.
From the work, time-dependent diffusion coefficients in HPC and the key parameters for durability design are proposed.
