Step-by-Step Guide

Step 1: Dissolve calcium into water prior to mixing with concrete.
Agitate the water to help the calcium flakes to dissolve. -
Step 2: A calcium addition of 2% by volume is a standard calcium amount to increase concrete setting times.
A five gallon bucket full of concrete would require only a small handful of calcium to accelerate the setting dramatically.
A medium Tim Hortons coffee cup of calcium would increase the set time of almost 400 pounds of mixed concrete. ,, Direct sunlight or warm ambient temperatures will cause the set time to increase even further.
Calcium is most useful for cold weather concrete applications where a high initial set strength is required to resist the potential damage to fresh concrete from freezing. -
Step 3: Mix concrete together as per normal using calcium enriched water.
-
Step 4: Place and finish concrete quickly after mixing since the set time will be accelerated.
