19 Dec 2017 Full-text (PDF) | Durability means the resistance to physical or chemical deterioration of concrete resulting from interaction with environment (physical deterioration) or interaction between constituents (chemical deterioration) of concrete. A durable concrete ensures corrosion resistance of embe
Four international durability testing procedures have been eva- luated in this study. It has been shown that durability performance of existing structure is different than the performance of concrete prepared in test samples whether these samples are prepared at site or at the lab due to the differences between the preparation

constituent materials that are commonly used to produce hydraulic cement concrete used in transportation structures and the durability problems that are associated with them. Sections on proportioning and test methods follow. CEMENTITIOUS MATERIALS. Cementitious materials, combined with water to produce a paste,
transporting aggressive agents through the pore structure of concrete. Therefore, porosity and permeability are important properties which affect the durability of concrete. 6.2. DURABILITY TESTS ON CONCRETE. Durability is the ability of concrete to resist weathering action, chemical attack and abrasion while maintaining
13 May 2014 mechanical, and durability tests were conducted in the laboratory to characterize the properties of the local cementitious mineral admixtures, cement mortar and portland cement concrete mixtures containing these admixtures. The results from this study indicated that the sulfate resistance of concrete was
