CivilSet™ Instant Post / Civil Concrete is 30 MPa dry concrete with special additives that ensures the concrete will set in 15 minutes (at 21 degrees). Warmer temperatures give a faster set time, colder temperatures a slower set time. CivilSet™ is premixable and that it will reach 20MPa in 3 days It can be used in the same way as RapidSet™ and High Strength RapidSet, however an additional special additive, allows for quick premixing immediately prior to use. Premixing will not disrupt its fast setting properties, making it ideally suited for civil applications. CivilSet™ is suitable for structural work.
