Abstract
The effect of a certain aggressive action is often aggravated if another aggressive action takes place at the same time. Examples of mechanisms with synergy are (i) salt-frost scaling and reinforcement corrosion, (ii) alkali silica reaction (ASR) and internal frost damage, (iii) leaching of lime and internal frost attack, (iv) leaching of lime and reinforcement corrosion, (v) internal frost and leaching, (vi) ASR and leaching. There are also other destruction mechanisms involved in synergy, such as different types of chemical attack. Synergetic effects should be considered in service life calculations of structures to be built. They should also be considered in connection with assessments of the residual service life of existing... (More)
The effect of a certain aggressive action is often aggravated if another aggressive action takes place at the same time. Examples of mechanisms with synergy are (i) salt-frost scaling and reinforcement corrosion, (ii) alkali silica reaction (ASR) and internal frost damage, (iii) leaching of lime and internal frost attack, (iv) leaching of lime and reinforcement corrosion, (v) internal frost and leaching, (vi) ASR and leaching. There are also other destruction mechanisms involved in synergy, such as different types of chemical attack. Synergetic effects should be considered in service life calculations of structures to be built. They should also be considered in connection with assessments of the residual service life of existing structures. In the paper some of these synergetic effects and their importance are discussed theoretically. The aim of the paper is merely to indicate the importance of considering synergy and not to treat this in great detail. (Less)
