Phimai concrete, salt resistant CPAC

Details
Concrete designed to have the property 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. Phimai Saline Soil Resistant Concrete CPAC has been 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.

With standard cube compression strengths ranging from 240 to 400 kg/sq.cm. (If a compression strength of more than 400 kg/sq.cm. is required, additional designs can be made.)

Properties
Resists chloride and sulfate penetration, resisting chloride penetration up to a concentration of 10,000 - 27,000 ppm and sulfate up to a concentration of 2,200 ppm.
Instructions for use and precautions
Water should not be added to make the concrete more liquid, as this will cause the concrete properties to be different from those designed.
Concrete should be properly vibrated according to the standard requirements for materials and construction for concrete structures (Engineering Institute of Thailand) to prevent cavities in the concrete and increase its strength and durability.
Concrete curing: Concrete should be cured immediately after it begins to set, continuously for at least 7 days, which can be done in several ways, such as water retention, concrete curing chemicals, covering with wet sacks and watering to keep it moist at all times, or spraying with clean water to keep it moist at all times, or according to the standard requirements for materials and construction for concrete structures.

Structures and buildings or special constructions that may require other appropriate curing methods besides this one.
