Product Q&A

Q:What is the main function of this cement expansion agent?

It induces controlled expansion in concrete to compensate for drying shrinkage and thermal contraction, preventing cracks and improving durability.

Q:What are the key benefits of using this admixture?

Key benefits include crack prevention (compensating up to 0.04% shrinkage), enhanced waterproofing (reducing pores by 30-50%), improved durability, and a self-stressing effect generating 0.2-0.7MPa pressure.

Q:What are the usage guidelines for mixing and curing?

Blend with cement for 1-2 minutes before adding aggregates. Wet cure for at least 7 days, which is critical for the expansion effect. Compatible with Portland and SPC cement.

Q:What are the packaging and shipping options?

Standard packaging is 25kg/bag (PP woven with inner liner) or 1-ton bulk bags. Shelf life is 12 months in dry conditions. Shipping methods include Express, Logistics Dedicated Line, and Ocean Shipping.

Q:What is the Minimum Order Quantity (MOQ)?

The MOQ is 1 Ton, but samples are available for testing purposes.
