Disadvantages Of Scc -

A common myth is that SCC exerts less pressure on forms because it flows easily. In reality, the opposite is often true.

Here is a detailed look at the primary disadvantages of using Self-Compacting Concrete. 1. Higher Material Costs disadvantages of scc

Maintaining consistency between truckloads is a major challenge. Environmental factors—like a 10-degree rise in temperature or a long transport time in traffic—can alter the workability of the mix. This often necessitates "re-dosing" the concrete with admixtures at the site, which introduces the risk of human error. A common myth is that SCC exerts less

| Condition | Why SCC is Disadvantageous | | :--- | :--- | | | High setup & material cost cannot be amortized. | | Poor quality control lab | Inability to measure viscosity & passing ability leads to failure. | | Old or variable formwork | Leakage and burst risk are too high. | | Slabs requiring early finishing | Slow setting delays troweling and opening to traffic. | | Hot weather > 35°C (95°F) | Rapid slump loss makes placement impossible without retempering (which is not allowed). | disadvantages of scc
