Type 2 cement is not available. What to do?
(OP)
What can be done to make up for this? Contractor is proposing to use type 1 cement. What can be added to make up for the loss in sulphate resistance. This is for a wastewater digester structure.
Thanks!
Thanks!

You may also ask the contractor to submit you a mill certificate for type-I from the cement producer. Then, compare the chemical composition from the mill cert with those of type II cement (as mentioned in ASTM). If they are within tolerance, then you probably can allow the contractor to proceed with type I cement. In my experience, I have seen very much similarity (except few) between two types of cements (for example, type II and III).

They are averages for cement that may be shipped to different locations. The cement for your project will most likely be different from the report given to you in advance. The mill reports do not represent the actual cement in the car that is devilered to the ready-mix plant.
Make sure you are not relying on values near the edge of the specs.
Also, the cement clinker ground may have been stored to provide a uniform supply during the cyclical sales demand.

By adding ground granulated blast furnace slag you may be able to get the properties you want. Check out http://www.slagcement.org/ for information.
