Plasticizers: Types, Uses, Classification, Selection & Regulation
It is almost colorless and odorless oily liquid. It is very slightly soluble in water but soluble in alcohols, hexane etc. while miscible and compatible with all the monomeric plasticizers used in PVC compounding. Melting point: 43°C (45°F; 230 K) Boiling point: 244-252°C at 0.7 kPa.
Impact of plasticizers’ types on the performance of calcium
On that account, it was assessed as an unsuitable plasticizer for calcium aluminate cement. Lignosulphonate based plasticizers performed better. In the cement stone, the highest amount of CAH 10 was observed. The cement pastes showed only slightly lower values of porosity compared to the reference material.
Handbook of Plasticizers | ScienceDirect
Plasticizers are used in so many products that every library should have this reference source of information on plasticizers readily available for its readers. This book should be used in conjunction with Plasticizer Database, which gives information on the present status and properties of industrial and research plasticizers.

- Why do we use plasticizer?
- The use of plasticizer is found to improve the desirable qualities of the plastic or green concrete. For making reinforced concrete or mass concrete of higher workability nowadays it has become a standard practice to use plasticizer or super plasticizer.
- What is the use of plasticizers in concrete?
- The reduction in water/cement ratio increases the strength and improves durability of the concrete. Sometimes plasticizers are used to reduce the cement content and heat of hydration in mass concrete. Generally following materials are used as plasticizers: 1.
- How much does a plasticizer increase workability?
- At the same water/cement ratio, the increase in workability may range from 30 mm to 150 mm slump depending upon the initial slump of concrete, type of cement, content of cement and dose of the plasticizer. A good plasticizer produces fluidity in concrete or mortar in a different way than that of an air entraining agent.
- Why do plasticizers increase the strength of concrete?
- The dispersing ability of plasticizers (water reducing admixtures) results in a greater surface area of cement exposed to hydration. For this reason there is an increase in early strength of concrete than that of admixture free concrete of the same water/cement ratio.
- Why do we use super plasticizer in concrete?
- Nowadays the use of super plasticizer has become a universal practice to reduce the water/cement ratio for the given workability. The reduction in water/cement ratio increases the strength and improves durability of the concrete. Sometimes plasticizers are used to reduce the cement content and heat of hydration in mass concrete.
- What materials are used as plasticizers?
- Generally following materials are used as plasticizers: 1. Ligno sulphates and their derivatives and modifications, salts of sulphonates hydrocarbons. 2. Polyglycol esters, acid of hydroxylated carboxylic acids and their derivatives and modifications. 3. Carbohydrates.
