What is the difference between type 1 cement and type 3 cement?
Our ready- mixers are trying to come up with a mix that we can strike with a straight edge and make it look nice but get up to 3500 psi in 4 hours Right now we are using a stone mix with 8 1/3 sack and 7.5 per cent NCA. • • • Report abuse • 08-22-2006, 10:21 748 in reply to 747 admin Joined on 08-22-2006 Posts 1,162 Re: New products Locked Essentially Type 3 is a finer ground version of Type 1 cement and would normally be made from the same clinker source as Type 1. For Type 3 cement there are minimum strength specifications in the ASTM standard C150 for 1 day strength (none are set for Type 1) and at 3 days the strength minimum specified is twice that set for Type 1 cement. The concrete strength requirement of 3500 psi at 4 hours is quite demanding and would need careful control of the concrete mix with accelerating additives/high range water reducers which do not retard the mix. • • • Report abuse • 08-22-2006, 10:21 749 in reply to 748 admin Joined on 08-22-2006 Posts 1,162 New prod
