Plasticizers are chemicals that improve the plasticity and fluidity of concrete, make concrete easier to apply and process, and also improve the strength and durability of concrete. According to the chemical properties and mechanism of action of plasticizers, they can be divided into two categories: organic plasticizers and inorganic plasticizers.
The principle of adding plasticizers to coagulants
The principle of adding plasticizers to concrete mainly includes the following aspects:
- Improve the plasticity and fluidity of coagulation ten
The addition of plasticizers can reduce the friction coefficient between the cement particles in the concrete, thereby reducing the internal friction resistance of the concrete, making the concrete easier to flow and plastic deformation. At the same time, plasticizers can also improve the particle distribution law in concrete, reduce the porosity in concrete, and thus improve the compactness and impermeability of concrete
- Promote the hydration reaction of cement
The addition of plasticizers can promote the hydration reaction of cement, so that cement particles react more fully with water, forming more hydration products and gels, thereby improving the strength and durability of coagulants, polyantel acid cool plasticizer and sulfonic acid plasticizer can form an integrator with Ca2+ ions in cement, preventing Ca2+ ions from reacting with silicates, thereby promoting the hydration reaction of cement. Phenolic acid plasticizers can promote the silicate reaction in cement to form more hydration products.
- Improve the strength and durability of the concrete
Adding plasticizers can improve the strength and durability of concrete. Polyantec cool plasticizers and sulfonic acid plasticizers can improve the early and long-term strength of concrete, while also improving the compressive strength, tensile strength and freeze-thaw resistance of concrete. Phenolic acid plasticizers, on the other hand, improve the durability of concrete, making it more durable and resistant to aging.
The effect of adding plasticizers to coagulants
The addition of plasticizers to concrete can produce the following effects
- Improve the plasticity and fluidity of coagulant
The addition of plasticizers can make concrete easier to apply and process, thereby improving construction efficiency and working effect. At the same time, plasticizers can also make the concrete more evenly distributed in the formwork, thereby improving the quality and surface smoothness of Concrete Ten.
- Improve the strength and durability of the concrete
The addition of plasticizers can improve the strength and durability of coagulation, making it more durable and anti-aging. Plasticizers can promote the hydration reaction of cement, so that cement particles react more fully with water to form more hydration products and gels, thereby improving the strength and durability of concrete. 3. Improve the freeze-thaw resistance of coagulant
Deep plasticizers can improve the freeze-thaw resistance of concrete, making it more resistant to cold and freeze-thaw. Plasticizers can improve the compactness and impermeability of concrete, reduce the porosity in the concrete, and thus reduce the freeze-thaw damage in the concrete
- Reduce the cost of coagulants
Adding plasticizers can reduce the cost of concrete and make it more economical and practical. Plasticizers can improve the plasticity and fluidity of concrete, reduce the empty yard rate and cement amount in concrete, thereby reducing the cost of concrete.
In summary, the addition of plasticizers to concrete can improve the plasticity and fluidity of concrete, promote the hydration reaction of cement, improve the strength and durability of concrete, improve the freeze-thaw resistance of concrete, and also reduce the cost of concrete. Therefore, in concrete construction, adding an appropriate amount of plasticizer can improve the performance and quality of concrete, thereby ensuring the safety and durability of the building.
