Rheobuild admixture has completely changed concrete technology, improving performance and sustainability

Rheobuild admixtures are specially designed to improve the flow characteristics of concrete without affecting its strength or durability. These additives work by altering the rheological properties of freshly mixed concrete, which refers to its ability to flow and form properly. The term ‘rheology’ itself originates from the Greek word ‘rheology’, which means flow, and ‘logos’, which means science. Therefore, Rheobuild admixture brings scientific precision to the art of concrete mixing.

The chemical principles behind Rheobuild additives

The core of Rheobuild technology is a complex mixture of polymers and surfactants that interact with cement particles at the molecular level. After adding the concrete mixture, these components will adsorb onto the surface of the cement particles, generating an electrostatic repulsion effect and making the particles more evenly dispersed. This dispersion reduces internal friction in the mixture, thereby improving fluidity and pumpability.

In addition, Rheobuild admixtures can also reduce the yield stress of concrete, making it easier to pour and solidify. However, they maintain the necessary viscosity to prevent aggregate segregation and water seepage – a key balance to ensure workability and structural integrity.

Application and benefits

1. High-performance concrete (HPC):

Rheobuild admixtures are particularly beneficial in the production of high-performance concrete, where achieving optimal consistency and pouring is crucial. They allow for lower water-cement ratios, resulting in higher strength and lower permeability – qualities necessary for durable structures.

2. Self-compacting concrete (SCC):

For self-compacting concrete, Rheobuild admixture provides ideal rheological properties, is easy to pour, and achieves excellent compaction without vibration. This not only accelerates the construction speed but also improves the quality of the finished product, especially in complex shapes and densely reinforced parts.

3. Can pump concrete:

In applications that require long-distance pumping or pumping through narrow spaces, Rheobuild admixtures can ensure that concrete maintains its stability and workability throughout the entire process. This is invaluable for high-rise buildings, tunnels, and other challenging projects.

4. Prefabricated components:

Prefabricated manufacturers benefit from Rheobuild additives by producing components with excellent smoothness and dimensional accuracy. Enhanced liquidity allows for complex mold design and faster production cycles.

5. Maintenance and Restoration:

When it comes to repairing existing structures, Rheobuild admixtures can create repair mortar that is easy to apply and has good bonding with the substrate. This resulted in durable repairs that matched the original structural performance.

Although Rheobuild admixtures have many advantages, their effective application requires precise dosage and careful integration into the mixing design. Overuse can lead to excessive liquidity, resulting in problems such as segregation and increased shrinkage. On the contrary, insufficient amounts may not provide the required rheological improvement. Therefore, ongoing research focuses on developing admixtures that are more tolerant and adaptable to different conditions. The innovation of Rheobuild technology includes intelligent additives that can respond to changes in the environment or mixture composition, ensuring consistent performance in different situations. Some products contain nanoparticles or biobased ingredients that further enhance functionality while promoting sustainability.
