Salt resistant concrete, salt water CPAC

Details
A concrete designed to have the properties of resistance to the penetration of chloride and sulfate that accumulate in the soil or nearby water sources, especially in the northeastern region of Thailand, which is a saline soil area. CPAC salt resistant concrete is designed to comply with the standard materials and construction requirements for concrete structures (Engineering Institute of Thailand). Both

Chloride and sulfate will have adverse effects on the concrete structure. Chloride will accelerate the rust reaction of the reinforcing steel, causing rust to occur faster. Sulfate will react with the concrete, causing the concrete to deteriorate faster and have less strength.

Suitable for the following types of work:
Structures that are in contact with chloride and sulfate that accumulate in the soil or nearby water sources, especially in the northeastern region of Thailand, which is a saline soil area.

Properties
Resists the penetration of chloride and sulfate, and can resist the penetration of chloride up to a concentration of 10,000 - 27,000 ppm and resist sulfate up to a concentration of 2,200 ppm.
Instructions for use and precautions
Do not add water to make the concrete more liquid, because it will make the concrete properties not as designed.
The concrete should be vibrated properly according to the standard requirements for materials and construction for concrete structures (Engineering Institute of Thailand) to prevent cavities in the concrete and to increase the strength and durability of the concrete.
Concrete curing The concrete should be cured immediately after it starts to set continuously for at least 7 days, which can be done in several ways, such as holding water, using concrete curing chemicals, covering with wet sacks and watering it all the time, or spraying it with clean water all the time, or according to the standard requirements for materials and construction for concrete structures (Engineering Institute of Thailand).
Structures and buildings or special buildings that may require other appropriate curing methods in addition to this method
