Standard Concrete Block by York Building Products
Concrete gray block by York Building Products is produced primarily from Portland cement, graded aggregates and water, which is then mixed, molded, cured, stored and delivered to a wide range of end users. Different aggregates mixed in the “batch” determine the type and ultimately the weight, compressive strength and a variety of other factors important to engineers, architects and contractors. York Building Products’ own local quarries and mining operations supply their plants with the necessary aggregates for the manufacture of concrete gray block.
Currently, their gray units are manufactured as normal weight concrete, lightweight, and recycled-aggregate. All three types of block satisfy the requirements of ASTM C-90 for load-bearing concrete units and, where applicable, meet the requirements of ASTM C-331 for lightweight units. Gray block continues to be an integral part of new homes, administrative buildings, medical centers, schools and many more of the structures in which we live, work, shop and play.
