Experimental Procedure – Chloride Data<br />
• As soon as a top mat rebar indicates corrosion initiation, concrete<br />
powder will be collected adjacent locations accessible from the sides.<br />
• Acid-soluble chloride concentration will be determined as a chloride<br />
threshold value.<br />
• This process will be repeated for every rebar in the top mat.<br />
• Average chloride threshold value <strong>and</strong> its time-to-corrosion initiation<br />
will be determined for the particular rebar material.
