Effect of Super-plasticizer Dosages on Fresh State Properties
Admixtures are added to the concrete to achieve a desired change in its properties. This study focuses the effects of super-plasticizer (Duraplast SP-400) dosages on the early age...
The effect of cement type and plasticizer addition on
1. Studies have found that plasticizer type and dosage play a key role in successful cement application in concrete. Three different plasticizer (SP, P and LS) effects on the viscosity of L and N cement paste investigations show that SP addition most efficiently reduces viscosity in pastes of both types of cement, P addition moderately, and LS
Effect of plasticizer dosage on properties of multiple
The effect of plasticizer on splitting tensile strength was similar to its effect on compressive strength: (i) at the same dosage of plasticizer, the strength of MRAC was 16% lower than that of the reference concrete. (ii) when the dosage increased from 0.8 to 0.9% and 1.0%, the strength was increased by 7 and 20%.
STUDY OF CONCRETE WITH VARIOUS TYPES OF PLASTICIZERS AND
concrete. The experiment focused on monitoring the resulting properties of hardened concrete, specifically the primary strength and modulus of the concrete elasticity and the developing parameters from 7 to 180 days were assessed. Keywords- Concrete, Plasticizer, Water-cement Ratio, Compressive Strength, Modulus of Elasticity.
IMPACTS OF USE OF SUPER-PLASTICIZER ON PROPERTIES OF CONCRETE
concrete is to improve the microstructure of the concrete. Mineral admixture addition is one of the methods to improve the microstructure of the concrete and super-plasticizer addition is good for reducing the pore diameter. The effect of super-plasticizer addition in improving the strength and workability properties of concrete also deserves
- Why are plasticizers used in concrete?
- Chemical substances called plasticizers, sometimes referred to as water reducers, are mixed into concrete to increase workability without weakening it. They aid in lowering the water content of the mixture, which is necessary to preserve the appropriate strength of the concrete.
- Do plasticizers increase mechanical strength?
- Plasticizers are used as reducers to reduce the water content to improve the physical properties of concrete. From which it was possible to demonstrate very favorable results from water reducers (plasticizers) that increase mechanical strength when these additives are used in sufficient proportion.
- What are the different types of plasticizers for concrete?
- As a result, the concrete paste becomes smoother and more user-friendly. Plasticizers come in various forms, such as polyglycerol esters and lingo sulfates, with dosage ranging from 0.1% to 0.4% by weight of cement. Hydrophilic Plasticizer : Improves concrete’s plastic and flow properties by increasing wet ability.

Hydrophilic Plasticizer : Improves concrete’s plastic and flow properties by increasing wet ability. Hydrophobizing Plasticizer : Increases air content in the mix, making the concrete more flexible.
- Why do we add plasticizing agents to concrete?
- The addition of plasticizing agents to the concrete composition preserves the ideal water content, which enhances the material’s functional qualities. An increase in fluidity causes the mixture to become more plastic, which in turn raises the density and strength properties.
- Why is plasticizer important?
- Because plasticizer is such an essential compound, the addition of which can provide better condition of quality and stability of concrete. achieve safer and more sustainable buildings. It is a process in which concrete plays an important role due to its own characteristics. It should also be noted that cracks and crevices in concrete are present.
