Citric Acid

BTA 5100

Citric acid is an organic acid naturally present in fruits, one of the ingredients that can be used as a retarder in a concrete mixture. As retarder serves to slow the timing of concrete hardening. In the implication the use of this material affects the time of hardening and compressive strength, therefore need a better control to get the optimal value. The results obtained the greater the addition of citric acid the longer the hardening of concrete and the greater workability of concrete.
