Organizing and summarizing search results for youPortland cement is a product that sets in a few hours and hardens over a period of weeks. It offers a very high initial resistance, which increases as the days go by. It takes 7 days to achieve type I resistance and 28 days for type II resistance. The strength of Portland cement can vary widely depending on the mix used and the conditions of curing of the product, but a typical concrete sets in about 6 hours and develops a compressive strength of 8 MPa in 24 hours.
