Poliretard HC is a retarding fluidifying admixture for concrete specific for long-distance transport that prevents cold joints in large massive castings. Poliretard HC is specially formulated to make high quality concrete where it is necessary to adjust and delay the start-of-setting times by reducing and controlling the development of hydration heat in the concrete.
STRENGTHS
- Poliretard HC acts as an effective dispersing agent that can reduce the W/C decrease by over 20%.
- It extends workability time of concrete, it controls the heat of cement hydration heat so that it can compensate for shrinkage.
- It improves mechanical strength, durability and resistance to chemically aggressive agents in the environment.
