Technical optimization and life cycle assessment
Replacing the superplasticizer to the solid-state superplasticizers, synthesized in this study, resulted in an improved slump retention in the concrete. This effect can be observed for each solid-state superplasticizer on each different scale of production (Fig. 3 (e)) and, importantly, allows meeting the requirements of concrete engineering
Bio-based admixtures - Sika
Polymers, the main component in superplasticizers, are added to concrete to influence properties such as workability, setting time and durability in a favorable way, depending on the desired application. This eco-friendly innovation is in line with one of Sika's stated corporate goals of sustainable product development.
Superplasticizer for low-viscosity concrete | MasterEase
The superplasticizer for low-viscosity concrete significantly improves concrete rheology during the entire processing time. With this technology, plastic viscosity can be reduced by up to 30%, which substantially reduces the pumping pressure required to pump the concrete on the construction site. MasterEase significantly facilitates the process
MasterEase superplasticizer for high performance concrete
MasterEase, a superplasticizer for low-viscosity concrete, improves the rheological properties of high-performance concrete, significantly facilitating its pumping, placing and finishing. It further allows concrete mix design optimizations for higher performance concrete and concrete mixes with a reduced CO 2 footprint.
Application of viscosity-reducing Polycarboxylate

- What is a superplasticizer in concrete?
- Superplasticizers allow a 30% or more reduction in water content. It is chemical admixtures that are added to the concrete to improve its flowing ability, they help to reduce the amount of water in the concrete and to improve the strength and durability of concrete. They achieve a reduction in water content without loss of workability.
- What is a superplasticizer used for?
- Superplasticizers are mainly used in pumping concrete, casting heavily reinforced members and precast elements of concrete. Advantages of Superplasticizer: Superplasticizers reduces the water content. It reduces the cement content. Also, increases the workability of concrete. It reduces the permeability of concrete. They are easy to placement.
- Is solid-state polycarboxylate superplasticizer better than liquid-state PCE?
- Herein a novel solid-state polycarboxylate superplasticizer (PCE) with low energy-consumption was designed and synthesized. In industrial application, solid-state PCE has exhibited better cement paste fluidity and concrete slump compared to liquid-state PCE.
- What is polycarboxylate superplasticizer (PCE)?
- 1. Introduction Polycarboxylate superplasticizer (PCE), when applied in cement-based materials such as cement paste, mortar and concrete, can significantly improve the workability, strength and durability of the material ( Zheng et al., 2019) by dispersing agglomerated cement particles ( Zhang et al., 2020 ).
- What are the advantages and disadvantages of superplasticizer?
- Advantages of Superplasticizer: Superplasticizers reduces the water content. It reduces the cement content. Also, increases the workability of concrete. It reduces the permeability of concrete. They are easy to placement. Increased long terms. It develops the early strength.
- Can a solid-state superplasticizer improve slump retention in concrete?
- Replacing the superplasticizer to the solid-state superplasticizers, synthesized in this study, resulted in an improved slump retention in the concrete. This effect can be observed for each solid-state superplasticizer on each different scale of production ( Fig. 3 (e)) and, importantly, allows meeting the requirements of concrete engineering.
