Block Concrete Brick

by Tyvek

Concrete gray block are produced primarily from Portland cement, graded aggregates and water; 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.

Currently our gray blocks are manufactured as normal weight concrete limestone, lightweight, 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 and integral part of new homes, administrative buildings, medical centers, schools and many more of the structures in which we live, work, shop and play.
