Influence of Hydrophobic Admixture and Curing Agent on Water-Resistant Concrete

The long-term performance of structural concrete is adversely affected by environmental loading such as heavy rainfall, temperature variations and freeze-thaw action. Adding waterproofing admixtures and curing agents to concrete mix can improve its durability. This research considers the application of crystallizing hydrophobic material followed by the application of curing agents, in wax and in liquid form, to fresh concrete which then goes through adverse and conventional curing conditions. The outcomes of this study showed that treating concrete with the same crystallizing protective material followed by a wax-based curing agent enhanced strength and reduced water absorption more effectively than concrete cured with water-based compound. The preserved strength in adverse curing condition was also better when concrete was treated with hydrophobic material and wax-based curing agent. Application of water-based curing agent in high water to cement ratio (w/c) concrete increased internal cracking, although water protection appeared to be improved even after adverse curing.
