When formulating CTA with RPP/RDP, it’s important to consider factors such as water retention capacity, workability time, open time before setting occurs, final set time after application onto the substrate surface, minimum thickness requirements for application onto walls or floors, etc. It’s also important to consider which type of cement should be included in order to achieve desired performance characteristics.
Generally speaking, Portland cements are preferred since they provide better hydration characteristics than blended cements do. Additionally, different types of fillers can be added depending on the desired end result; some fillers are designed specifically for improved adhesion while others are designed for improved waterproofing capabilities. Finally, additives such as accelerators may need to be included in order to speed up setting times if desired.
