Abstract:
Guide for Durable Concrete, prepared by ACI Committee 201, was published in the December 1977 ACI Journal. It classified the factors that can cause deterioration of concrete into five categories: (1) freezing and thawing, (2) aggressive chemical ex. posure, (3) abrasion, (4) corrosi on Of Steel and other embedded material, and (5) chemical reactions of aggregates. The simple explanation of what one needs to do to achieve concrete that does not deteriorate is to follow the rules set forth in the Committee 201 report. However, it is believed useful to point out certain threads that run through the understanding of deterioration-producing processes and to Consider the degree to which one appropriately balances increased protection against increased cost. Concrete will not deteriorate if the specifications covering its production are correct and are followed. It follows, therefore, that when concrete does deteriorate either
