MasterGlenium 315C

High-range water-reducing admixture for high-quality concrete

​How does MasterGlenium 315C work?

MasterGlenium 315C is a novel third-generation superplasticizer based on modified polycarboxylic ether, primarily developed for use where concrete with the highest durability and performance is needed.

What differentiates MasterGlenium 315C from other generations of polycarboxylic ether is a unique mechanism of action that greatly improves the effectiveness of cement dispersion.

Traditional superplasticizers based on melamine and naphthalene sulfonates are polymers that are absorbed by the cement granules. They wrap around the granules' surface areas at the earliest stage of the concrete mixing process. The polymer chains' sulfonic groups increase the negative charge of the cement particle surface and disperse these particles by electrical repulsion. This electrostatic mechanism causes the cement paste to disperse, meaning that less mixing water is needed to achieve a given concrete workability.

MasterGlenium 315C has a different chemical structure to traditional superplasticizers, as it consists of a carboxylic ether polymer with long side chains. At the beginning of the mixing process, it initiates the same electrostatic dispersion mechanism as a traditional superplasticizer. However, the side chains linked to the polymer backbone generate a steric hindrance, greatly stabilising the cement particles' ability to separate and disperse.

Steric hindrance provides a physical barrier (alongside the electrostatic barrier) between the cement grains. This process produces flowable concrete with significantly reduced water content.

What is MasterGlenium 315C used for?

Its excellent dispersion effect makes MasterGlenium 315C the ideal admixture for the high-quality concrete industry. Working with an extremely low water/cement ratio allows the manufacture of high-performance concrete with high early (18-24 hours) and final strengths. High-density, low-permeability concrete is also produced.

What are the benefits of MasterGlenium 315C?

• ​Flowable concrete with the lowest water-cement ratio without segregation or bleeding

• Reduction of curing cycles (time or temperature)

• Opportunity to eliminate steam curing

• Allows concrete production at low temperatures

• Less vibration needed, even with congested steel reinforcement

• Less labour required

• Improves concrete surface finish and texture

• Compared to traditional superplasticizers, adding MasterGlenium 315C will improve the physical properties and durability of concrete
