The content of hydroxypropyl methylcellulose in concrete
The content of hydroxypropyl methylcellulose in concrete. This is something we will consider when we use it for concrete. Let me analyze it for you today.
When the content does not exceed 0.05%, its participation can significantly improve the fluidity and viscosity of the foamed concrete slurry.
After dissolving, a moist, flexible film is formed between the solid particles and gas-phase bubbles, which has an excellent smoothing effect during mixing. This also allows the bubbles to turn into self-aligning “balls” within the slurry in impossible disillusionment, which effectively improves the flowability of the fresh slurry.
However, if the amount exceeds 0.5%, the slurry will become too viscous and flowability will be greatly reduced. Therefore, the content of 0.05% not only ensures the slump, but also stabilizes the air bubbles, which is the intake.
