Abstract: Most concrete structures are designed to last for one hundred years or more. During this lifetime a structure is exposed to environmental influences. Whether it can resist these environmental influences depends, among other things, on the ingress rate of liquids and gases. The rate of ingress has a direct relationship with pore structure and connectivity . They are influenced by several factors during design and construction. An important factor during the construction phase is the curing of concrete. To achieve the required durability several methods are applicable: liquid membrane, plastic film, fresh water etc.
This paper reports the effects of different curing methods with two types of cement (CEM I and CEM III/B). After curing, the concrete was analysed using concrete microscopy and rapid chloride migration tests. Based on the results it can be stated that concrete made with CEM III/B is more sensitive to variation of curing than CEM I.
