Chloride limits in the ACI 318 building code requirements

ride-content limits currently in ACI 318-95 with a value called the chloride corrosion threshold. Corrosion threshold The corrosion threshold is the amount of chloride ion that must be present in concrete, along with mois-ture and oxygen, for corrosion to be-gin. When tested by water-soluble test methods (see related article on various chloride test procedures), the thresh-old is generally,ASTM C1218 / C1218M - 20 Standard Test Method for,Chloride content, along with other factors, can be indicators for the possibility of corrosion of embedded metallic materials. This test method is used to determine the water-soluble chloride content in cementitious mixtures, either in new construction or existing structures.

For example, water-soluble chloride content could increase,International Standards and codes For Chloride Limits in,,6- ASTM C 1152/C 1 152M-97, “Standard T est Method for Acid-Soluble Chloride in Mortar and Concrete”, V olume 04.02, Annual Book of ASTM Standards, American Society

Chloride limits for reinforced concrete - Aggregate

The initial chloride content of the mixtures was varied between the background amount up to 2% by weight of cementitious materials by adding controlled amounts of calcium chloride. The initial chloride content was verified by measuring the acid soluble chloride content in accordance with ASTM C1152. The water-soluble chlorides were measured at an age between 28 and 42 days in accordance with,Analysis of total chloride content in concrete,Chloride in mixing water could be higher than the ASTM limits with low w/c ratios.

ASTM C-1218 - Chloride Testing

There are two major types of Chloride tests, Acid-Soluble and Water-Soluble. Acid-Soluble (ASTM C-1152, FM 5-516) is theoretically a total extraction method, whereas Water-Soluble (ASTM C-1218) run results that are generally twenty to twenty-five percent less. Also the Water-Soluble, due to differences in the method, take an extra day in the turn-around time.
