Abstract | The main purpose of this research is to study the feasibility of curing concrete by sea water. Specimens made from three types of concrete mixes, water-cement ratios of which are 0.65, 0.55 and 0.40, were prepared. They were cured over a period of 7 days immediately after its demolding at 1 day. The curing of concrete specimens were made by either immersing them in sea water and/or covering them with burlaps moisture with sea water. Compressive strength, flexural strength and length change of the concretes and corrosion of reinforcement embedded in concrete were tested at the end of curing and at later ages. The results were compared with those that were cured in a standard way. Following are the main findings: 1. There are no adverse effects on strength and shrinkage of concrete when concrete is cured by sea water. These trends were observed to be more pronounced when water-cement ratio was high. 2. Corrosion of reinforcement embedded in concrete takes place even in the region where alkalinity remains when concrete is cured by sea water. However, this can be prevented by either lowering the water-cement ratio of concrete or providing enough clear cover to the reinforcement. |
