Plasticizers are also referred to as water reducers. Plasticizers are added 0.1-0.5% by weight of cement. Plasticizers can reduce the need for water by 5-15%. Plasticizers are used to increase the plasticity of polymer materials such as PVC and as a water reducer in concrete mixtures.
This fortifier makes the concrete mix begin to harden within five minutes, so be sure to mix only as much as you can use in that time frame. Best For Cold Temperatures. 3.
There are many reasons to add polymers to concrete overlay mixes. Polymers improve adhesion to the old surface, flexural strength, tensile strength, and freeze/thaw durability. They also reduce permeability, the intrusion of chlorides, salts, and carbon dioxide. They increase abrasion resistance and can be applied in very thin cross sections.

How to Use/Dosage. VMA is one of the few concrete ingredients that does not need to be precisely dosed by weight. If your mix is too fluid or showing signs of segregation, simply sprinkle about 1/8 teaspoon (about 1/2 gram) into your mix, mix for 30 seconds, and observe the viscosity. Add more very gradually if needed.
Requirement for producing flowing concrete is defined in ASTM C 1017. The effect of superplasticizers in concrete flow is illustrated in the chart below: Figure 3 Relation between Flow Table and Water Content of Concrete with and without Plasticizers (Neville, 1995).
QUIKRETE® Concrete Acrylic Fortifier (No. 8610) is an acrylic resin admixture designed to enhance bonding and water resistance of concrete patching materials, stucco, surface bonding cement, thin-set mortars and tile grouts. Exceeds the requirements of ASTM C 1438. Available in: 1 …
Added at the job site and keep concrete flowable for a short period of time. At some point, the concrete will lose slump quickly. Type G superplasticizers. Can be added either during batching or at the job site. This admixture will delay setting, but cause the concrete to be flowable for a longer period of time which could delay finishing.
Requirement for producing flowing concrete is defined in ASTM C 1017. The effect of superplasticizers in concrete flow is illustrated in the chart below: Figure 3 Relation between Flow Table and Water Content of Concrete with and without Plasticizers …
Superplasticizers, also known as plasticizers or high-range water reducers (HRWR), reduce water content by 12 to 30 percent and can be added to concrete with a low-to-normal slump and water-cement ratio to make high-slump flowing concrete. Flowing concrete is a highly fluid but workable concrete that can be placed with little or no vibration or ...
Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve their flowing ability, they help to reduce the amount of water in the concrete and to improve ...
Plasticizers and superplasticizer are added to concrete mixtures in order to reduce the water: cement ratio, thereby, reduces the water requirement in the production of concrete. The main difference between plasticizers and superplasticizers is that plasticizers can reduce the need for water by 5-15% whereas superplasticizers can reduce the ...
Superplasticizers (SP's), also known as high range water reducers, are additives used in making high strength concrete. Plasticizers are chemical compounds that enable the production of concrete with approximately 15% less water content. Superplasticizers allow reduction in water content by 30% or more. These additives are employed at the level of a few weight percent.

Plasticizer us in concrete for workability, Strength, and Durability of concrete.Plasticizer in concrete for Water-reducing admixtures usually reduces the required water content for a concrete mixture by about 5 to 12 percent.. The use of water-reducing admixtures is defining as Type A in ASTM C 494.The WRA mainly affects the fresh properties of concrete.
