Precast concrete - Wikipedia

Precast concrete is a construction product produced by casting concrete in a reusable mold or "form" which is then cured in a controlled environment, transported to the construction site and lifted into place ("tilt up"). In contrast, cast-in-place concrete is poured into site-specific forms and cured on site. Precast stone is distinguished from precast concrete using a fine aggregate in the

Concrete Reinforcing Fibers - Sika

Fiber reinforced concrete is a composite material and therefore, all fibers are tested in the concrete to prove their performance. Fibers begin to function in a structural supportive manner when the concrete matrix starts to crack, just like traditional reinforcement. The crack has to occur for the load to switch from the concrete to the
