Research output: Patentpeer-review


The invention relates to a construction method making use of concrete for application in an integral process containment vessel where the entire or part of large-scale vertically stacked multi-effect distillation and/or separation processes and especially vertically stacked multi-effect distillation desalination processes take place. According to the present disclosure, such an integral process containment concrete vessel is divided into at least two different process zones, where each process zone marks a different degree of severity of attack under respective process conditions. In each of the said zones, the part of the integral process containment vessel that is in direct contact with the process conditions is constructed by means of a concrete mix that is matched to the process conditions in the said zone. Thus the resultant prestressed integral process containment vessel, constructed by means of a multi-layer, and/or multi-segment method or by means of jump-forming, slip-forming, climb-forming or the like, is functionally graded with at least two different concrete mixes possessing significantly different properties and therefore costs and thereby arriving at a durable and cost effective construction method.
