Product Description

Concrete Expansion Agent | Shrinkage Compensation Admixture

A high-performance chemical admixture that induces controlled expansion in concrete/mortar to compensate for drying shrinkage and thermal contraction. Prevents cracks while improving durability.

Key Benefits
(1) Prevents Cracks - Compensates for up to 0.04% shrinkage strain
(2) Enhances Waterproofing - Reduces capillary pores by 30-50%
(3) Improves Durability - Extends service life in harsh environments
(4) Self-Stressing Effect - Generates 0.2-0.7MPa expansion pressure

Usage Guidelines
Mixing: Blend with cement for 1-2 minutes before adding aggregates
Curing: Wet cure for ≥7 days (critical for expansion effect)
Compatibility: Works with Portland/SPC cement. Test with other admixtures.

Packaging & Shipping
Standard: 25kg/bag (PP woven with inner liner)
Bulk: 1-ton bags
Shelf Life: 12 months in dry conditions
MOQ: 1 tons (samples available)

Land Transport

Advantages: Cost-effective; ideal for large-volume, heavy, or bulky goods.
Disadvantages: Longer transit time (typically 15–60 days).
Modes:
* FCL (Full Container Load): Full container used by one shipper; suitable for high-volume cargo.
* LCL (Less than Container Load): Shared container space for smaller shipments.
* RORO (Roll-on/Roll-off): For wheeled or self-propelled cargo such as vehicles and machinery.
Common Cargo: Machinery, large furniture, ores, electronics.

Advantages: Fast (usually 1–5 days); ideal for high-value or time-sensitive cargo.
Disadvantages: Expensive and limited cargo capacity.
Modes:

* Freighter Aircraft: Dedicated cargo planes for bulk air shipments.
* Passenger Belly Cargo: Uses spare space in passenger aircraft.

Common Cargo: Electronics, perishables, urgent samples.

Advantages: Flexible and ideal for regional or short-haul transport; integrates well with sea or air freight.
Disadvantages: Limited by geography and border formalities for international routes.
