Set Control Concrete Admixtures – Accelerators & Retarders

Why Use Accelerating Admixtures? Accelerating admixtures are used to speed up the set time and increase the early strength of concrete. Accelerators are most frequently used in the winter months to allow final finishing operations to take place within a reasonable time after the concrete is initially poured. Main Types of Accelerators: ASTM Classifications Type […]

What is an Isolation Joint?

What is an Isolation Joint? An isolation joint is a separation of an existing concrete slab from a new concrete slab or wall. A piece of expansion joint (usually ½” wide and made of cork or recycled fiber material) is placed against the existing concrete slab and when the new concrete slab is poured, this expansion joint separates the

Can You Drive Concrete Trucks and Heavy Equipment on Concrete Driveways?

Unless the concrete contractor that built the concrete driveway designed it to withstand loads heavier that regular passenger vehicles, the answer is NO. Concrete driveways are typically poured four inches thick, giving the concrete driveway enough strength to withstand loads of regular vehicles (up to approximately 8,000lbs). A fully loaded concrete truck can weigh over 70,000lbs, almost nine times
