Self-Consolidating Concrete (SCC) Static Segregation Column Mold
The Economy SCC Static Segregation Column Mold is a crucial tool for evaluating the potential static segregation of self-consolidating concrete (SCC) mixes. It measures the resistance of fresh SCC to the static segregation of normal-weight coarse aggregate, a critical factor for ensuring structural integrity.
Static segregation occurs when the coarse aggregate in fresh SCC settles downward, leading to a non-uniform mixture. This can significantly reduce the concrete's flowability and block its passing ability, especially during placement in vertical columns and deep wall sections. If the concrete cannot flow smoothly around reinforcement and into restricted formworks, it can result in voids, flaws, and honeycombing, compromising the final strength and durability of the structure.
This mold provides a reliable method to test for and prevent such issues before placement. The test involves filling the column with fresh SCC and allowing it to stand undisturbed. After a set period, the column is separated into sections, and the aggregate content in each section is analyzed to determine the degree of segregation.
Features:
- Assesses Segregation Risk: Accurately determines the potential for coarse aggregate to segregate in fresh SCC mixes.
- Easy, Single-Operator Use: Features a user-friendly clamping and collection system that allows a single operator to conduct the test efficiently.
- Rapid, Reliable Results: Provides quick and actionable data to ensure your concrete mix meets performance standards.
- Durable Construction: Built to withstand the rigors of field and lab use.
