Fastset instant post hole structural concrete is dry bagged premixed concrete with special additives that will make the concrete set in 15 minutes (at 21^o Celsius) when added to water. However, warmer outside temperatures (summer) means a faster set time, colder temperatures (winter) means a slower set time.

Fastset bagged concrete will reach 20MPa after 28 days and is suitable for structural projects such as deck posts and non structural projects such as fence posts.

When mixed according to the instructions, Ezymix achieves a set in minutes and a 28-day strength of 15MPa.
