New Methodology for Designing Self-Compacting Concrete

Nov 01, 2001· A new segregation-controlled design methodology is introduced for self-compacting concrete (SCC). The theory suggests that aggregate segregation is governed by the yield stress, viscosity, and density of the cement paste matrix. The concept of a rheological self-flow zone (SFZ) for concrete is introduced where aggregate segregation is avoided ...

Stone Compaction: The Ways It'll Impact Your Project

Compacting very deep layers of stone can be extremely difficult and may lead to poor results. For this reason, deep project areas require stone compaction to be completed in layers. Only after one layer is properly compacted can more stone be introduced. Depending on the depth, you may need to make 3 or more passes before the surface is solid.
