  • Concrete vs Cement Whats the Difference

    The type of cement used in the concrete has an influence on setting time and the strength that the placed material develops Generally Type 1 cement is used for most projects but Type 3 is often used for precast shapes where quicker curing time allows for faster removal of reusable forms

  • Whats the difference between Type III cement and CSA

    Generally Type I cement based concrete reaches about 60 of its 28 day strength in the first 3 days Type III cement achieves about 70 of its 28 day strength after 3 days That is indeed a little faster than Type I With either Type I or Type III portland cement continued strength gain requires continuous wet curing for weeks
