OUR AGGREGATE: Douglassville Quarry’s underlying rock units, a crystalline intrusive igneous rock commonly referred to as Diabase, and an adjoining metamorphic gray/blue-gray argillite, both yield exceptionally durable construction aggregate. All materials produced at this operation are suitable for use in hot-mix asphalt, ready-mix concrete, drainage applications and general use.

In addition to using a coarser sand, it is important to use as little sand as possible. Often, the sand portion of the total aggregate fraction is several percentage points lower than is typi-cally used. In many areas, it is not uncommon to find balanced high-strength concrete mix designs with sand comprising only 39% of the to-tal aggregate

High-performance concrete is used basically for two reasons. Higher Compressive Strength. Workability and Compactibility. In large and complex construction projects, congestion of bars is a very common phenomenon. It becomes very tough to compact concrete with vibrators.

High-Strength Concrete. In the early 1970s, experts predicted that the practical limit of ready-mixed concrete would be unlikely to exceed a compressive strength greater than 11,000 pounds square inch (psi). Over the past two decades, the development of high-strength concrete has enabled builders to easily meet and surpass this estimate.
