    in concrete strength with curing age from the graph showed that there was a steady increase in strength of concrete with number of days of curing. A regression analysis was performed on the results. This showed a linear relationship between concrete strength and curing age validating the observed phenomenon. The result showed that concrete gains approximately 0.385N/mm2 per each day of Effect of Age on Concrete Strength. The strength versus gel/space ratio relationship has a general application because the amount of gel present in the cement paste at any time is itself a function of age and type of cement. The latter relation thus allows for the fact that different cements require a different length of time to produce the same quantity of gel. In concrete practice, the ...Effect of Age on Concrete Strength Civil Engineering ForumAbstract: Concrete is the most important material in civil engineering.
