Plasticizers | ExxonMobil Product Solutions
Jayflex high-molecular-weight plasticizers provide an optimum balance of properties with outstanding performance and permanence. Adipate plasticizers Jayflex adipate plasticizers can be used as a primary plasticizer but, more typically, are used in blends with general-purpose phthalates to improve low temperature properties.
Impact of plasticizers’ types on the performance of calcium
They reported beneficial performance, as the material based on CAC with superplasticizer showed the highest compressive strength among studied mortars. But on the other hand, the hydration was retarded (by about 2 h) and specific hydration heat power decreased as well.
Chemical Admixtures - Cement
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
15 Types of Admixtures Used in Concrete - The Constructor
Normal plasticizer reduces the water demand up to 10%, mid-range plasticizers reduce the water demand up to 15% while super plasticizers reduce the water demand up to 30%. Calcium, sodium and ammonium lignosulphonates are commonly used plasticizers.
Impact of Plasticizers’ Types on the Performance of Calcium
In the case of calcium aluminate cement (CAC), they are also widely employed, but their impact has not been properly studied yet. In this paper, four different bases of plasticizers are...
- Does a superplasticizer cater to the properties of CAC?
- For the first time in literature, we report a superplasticizer that caters to the properties of CAC such as high rate of surface development and surface charge. While neat CAC was almost unworkable after 1 hour, with the addition of only 0.4% of the optimized superplasticizer, 90% fluidity retention was achieved.
- What is a plasticizer chemistry?
- Plasticizers are the most used additives in the plastics industry. They are generally available as non-volatile, colorless liquids. They improve the properties of the polymer. With several plasticizer chemistries available in the market choosing the right one can be daunting. In this guide, you will read more about:
- What are plasticizers & how do they work?
- Plasticizers are non-volatile organic substances (mainly liquids) added into a plastic or elastomer. They are also usually cheaper than other additives. They improve the following properties of the polymers: Plasticizers increase the flow and thermoplasticity of a polymer.
- Are superplasticizers harmful to CAC systems?
- The high affinity between these superplasticizers and cement particles were found to be detrimental in CAC systems. Utilization of a monomer that, instead, facilitates gradual adsorption of a superplasticizer provides workability retention.
- Which plasticizers are used to analyze water vapor permeability (WVP)?
- The film with lower WVP (∼0.45 M/G immersed in CaCl 2 for 1 min) was analyzed for mechanical properties and WVP, including sorption isotherms, using different plasticizers (glycerol, sorbitol, fructose, and PEG-8000) under different relative humidities. 2.4. Water vapor permeability (WVP)
- Can PCE superplasticizers be intercalated in calcium aluminate cement?
