Sapci products - Accelerated concrete
Ready mixed concrete - Accelerated concrete
Description:
Climatic conditions have a very important influence on the quality of concrete. We must be concerned about it from its manufacture through its transport, and then its implementation.
As a general rule, when the temperature measured on the site is below -5 °C, placing concrete is not recommended.
Between -5 °C and + 5 °C, it can only be done with efficient means to prevent the damaging effects of cold.

Stripping time limit as a function of temperature
Consequences of the drop in temperature:
On concrete, the drop in temperature within a range that does not reach freezing slows down the exothermic hydration reactions of the cement and we will have:
- A delay in taking
- An extension of the curing time
- An increase in bleeding
- A risk of freezing
- Drop in mechanical resistance
SARL SAPCI has put its experiences by offering its customers an accelerated concrete, a concrete that meets quality requirements and allows pouring in cold weather.
Benefits:
Accelerated concrete is beneficial for:
- Faster concreting in cold weather, allows work to be carried out in unfavourable temperature conditions (between 5 °C and 10 °C).
- Faster commissioning
- Accelerate the setting of the concrete in order to increase the formwork rotations
- Better management of equipment and people
- Catch up on the worksite delay
- Get ahead of the schedule
- Remove form faster
- Ensure concrete setting in cold weather
- Reduction of the cost of labor
