Web3.6.4 Sulfate attack. Sulfate attack of concrete is a complex process, which includes physical salt attack due to salt crystallization and chemical sulfate attack by sulfates from soil, groundwater, or seawater. Sulfate attack can lead to expansion, cracking, strength loss, and disintegration of the concrete. WebThe purpose of this chapter is to summarize comprehensively our understanding of batch crystallization processes. A generalized analytical process description of a batch crystallizer is developed and its application illustrated to evaluate the performance characteristics of different types of batch crystallizers operated under different modes.
