Permeability of Concrete Containing Limestone Powder in Marine Curing Conditions
https://orcid.org/http://orcid.org/0000-0001-5694-0366
The main objective of this experimental work is to investigate the effect of partial replacement of cement with limestone powder on the permeability of concrete, especially in severe curing conditions. For this evaluation, 5%, 15% and 30% cement of concrete mix design were replaced by limestone powder and two different curing conditions applied to the concrete samples. Some of the concrete specimens were submerged in seawater till the age of the test, whereas others were cured in standard conditions. A series of tests, including the Rapid Chloride Penetration Test (RCPT), water penetration test under pressure, and water absorption test were carried out at ages 7, 28 and 90 days to evaluate the permeability of concrete containing limestone. The results show that the penetration of chloride ion increases with the increase in limestone content in concrete. For seawater conditions, samples with 5% and 15% limestone had less chloride permeability than the control sample. For concrete with 30% limestone powder, the permeability significantly increases for both curing conditions. In the normal conditions, water penetration depth and water absorption increased with the increase in limestone content. This trend was observed for the water penetration depth of samples in seawater, but like RCPT results, the water absorption of samples containing up to 15% had less permeability to the control sample. The compressive strength of all specimens cured in seawater was reduced compared to the standard curing condition.
