Good day, everyone. Today's experiment will primarily test the water retention properties of Hydroxy Propyl Methyl Cellulose.

Our prepared mortar mix design is as follows:

350 kilograms cement, 650 kilograms medium-grade sand, with 2.5 kilograms of HPMC. added.

We have compared different brands of HPMC, maintaining consistent proportions throughout.

After mixing, we placed the samples in an oven to simulate extreme summer construction conditions.

The experimental environment was set to: 45°C temperature, wind speed approximately force 5, for 24 hours.

This allows for a more realistic assessment of the cellulose's water retention performance under high temperatures and strong winds.

Following a day of drying, we tested the surface strength of the mortar.

The results were unequivocal—

Samples utilising our company's cellulose exhibited a more robust, denser surface with significantly higher strength.

This demonstrates that our cellulose effectively retains moisture even in high-temperature drying conditions, preserving the mortar's workability and enhancing the final quality.

Consistent performance, outstanding results—that's our HPMC.
