Events and needs leading up to, during and after a typical Concrete Pour.

Timeline

Concrete Admixtures and Modifiers are substances added to the mix before or during the pour to enhance its properties and performance. Purposes include improving workability, Accelerating or Retarding setting times, Strength, or Resistance to environmental factors. Main Types: Plasticizers, Accelerators, Retarders and Air-Entraining Agents

Vibration tools may be used to help settle the concrete and remove any trapped air bubbles, ensuring a dense and strong final product. 

Concrete Screeding is a crucial process in the Finishing of concrete surfaces that involves leveling and smoothing the freshly poured concrete. This step is essential for achieving a uniform surface with the correct elevation and grade. Screeding typically follows the initial placement of concrete and is performed using a straightedge or screed board, which is dragged across the surface to remove excess material and fill in low spots. The screeding process helps to ensure that the concrete slab is even and free of defects, setting the stage for subsequent Finishing work such as Troweling or Brooming.
