Low to high polarity esters provide utility in a wide range of elastomers including nitrile, polychloroprene, EPDM, chlorinated polyethylene, and epichlorohydrin. Plasticizer-elastomer interaction is governed by many factors such as solubility parameter, molecular weight, and chemical structure. Compatibility and performance attributes are key factors in developing a rubber formulation for a particular application. [7] Plasticizers are additives that are used to reduce the water content at a given workability or achieve higher workability at the same water content. These additives are organic substances or a combination of organic and inorganic substances. Plasticizers Dosage When adding dyes or tones to a mix this is an absolute must as even the slightest change to the volume of dye or colouring added can cause an easily noticeable visual difference in colour or tone between different mixes. Typically most standard water reducing admixtures can reduce the required water volumes by up to around 10% but in recent years developments within the admixture field have seen newer mid-range water reducers emerge. Although generally they only reduce water volumes up to around 8% they are generally more stable when exposed to a range of different temperatures. Retarding Admixtures

Plasticizers are surfactants inducing a negative charge to the cement particles. This causes inter-particle repulsion between the cement particles dispersing the fine cement particles. As the particles start dispersing, the entrapped water is released increasing the flowability of the concrete mix.

"Design and function of novel superplasticizers for more durable high-performance concrete (Superplast project)". Cement and Concrete Research. 38 (10): 1197–1209. doi: 10.1016/j.cemconres.2008.04.007. The use of superplasticizers may produce high strength concrete (compressive strength up to 22,000 psi). Superplasticizers can also be utilized in producing flowing concrete used in a heavy reinforced structure with inaccessible areas. Do I need plasticiser in 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. Plasticizers and superplasticizers retard the curing of concrete. Does plasticizer weaken concrete?

Plasticizers used in PVC and other plastics are often based on esters of polycarboxylic acids with linear or branched aliphatic alcohols of moderate chain length. These compounds are selected on the basis of many critieria including low toxicity, compatibility with the host material, nonvolatility, and expense. Phthalate esters of straight-chain and branched-chain alkyl alcohols meet these specifications and are common plasticizers. Ortho-phthalate esters have traditionally been the most dominant plasticizers, but regulatory concerns have led to the move away from classified substances to non-classified which includes high molecular weight ortho-phthalates and other plasticisers, especially in Europe.Polycarboxylate superplastics, also known as high-grade water reducers, they are chemicals that are used where well-dispersed particle suspensions are required. Polycarboxylate ether, also called PCE superplasticizer, is a new type of high-performance superplasticizer. It has characteristics like low dosage, high water reduction rate, remarkable enhancement effect, low slump loss over time, and little effect on setting time. The use of a polycarboxylate ether superplasticizer has the following advantages. Dosed at 3oz (liquid) per 100lbs cement (@ .75 ounces per 25lbs cement) would be around 170 batches per 1-gal (850 batches per 5-gal) On the whole today adding the correct admixture to your concrete mix is generally preferred over adding PVA or SBR, but for smaller more domestic concreting jobs it’s well worth while knowing this. Plasticizers are commonly added to polymers such as plastics and rubber, either to facilitate the handling of the raw material during fabrication, or to meet the demands of the end product's application. For example, plasticizers are commonly added to polyvinyl chloride (PVC), which otherwise is hard and brittle, to make it soft and pliable; which makes it suitable for products such as shower curtains, vinyl flooring, clothing, bags, flexible plastic tubing, and electric wire insulation/coating.

Hydroxylated carboxylic acid plasticizers increase bleeding in concrete, which is harmful to concrete.

Can I use Fairy Liquid as a plasticiser?

The naphthalene based superplasticizer is often used to formulate high fluidity, high strength and high performance concrete. It is especially suitable for use in the following concrete projects: fluidized concrete, plasticized concrete, steam-cured concrete, impermeable concrete, waterproof concrete, natural curing prefabricated concrete, reinforced and prestressed reinforced concrete, high-strength ultra-high-strength concrete.
