Can you mix rapid set and normal concrete?

Rapid Set No-Mix Concrete CANNOT be mixed in a wheelbarrow or mechanical mixer like normal concretes. The additive used in the mix reacts instantly with cement allowing very little to no mixing time or compaction. Requires no mixing.

Can you mix different types of concrete?

It is perfectly possible to use two types of cement simultaneously in one recipe for concrete composition provided that the rate of hydration (such as rapid hardening and low heat cement) and setting time is not in conflict. If want to achieve a specific color for the concrete, use a coloring admixture.

Is rapid set concrete as strong as normal concrete?

Fast-setting concrete isn’t just simple and fast, it’s also durable and strong, reaching 4000 psi — or pounds of force per square inch —after a month. That’s stronger than the concrete used for foundations on most homes.

Do you need to mix fast setting concrete?

Using fast-setting concrete requires the project to be fast from start to finish. If the mix begins to harden and set in the bucket before the job is complete, throw it out. Even if only a very small amount is needed to complete the project, mix fresh concrete to finish the job.
