Development of strength and microstructure in high strength massive concrete
High strength concrete undergoes a quicker early age temperature development and correspondingly a higher early-age strength. However, the high early temperatures can adversely affect the long-term strength and the durability of the concrete. This paper investigates the influence of temperature on microstructure, hydration, and compressive strength of high strength concrete in massive concrete structures. The aim is to identify mechanisms, which affect or even jeopardize the long-term performance of high strength concrete structure, which contain substantial hydration-related strength gradients. Experimental work has been done on concrete walls. Research parameters were the depth of the wall, the size of the wall and type of cement. Temperature histories at different locations in the walls are recorded and the degree of hydration, amount of hydration products and microstructure of concrete at those locations were measured using DSC and MIP. The effects of cement type and curing temperature on the hydration processes, hydration products, microstructure development and compressive strength were presented.
