Specialty Concrete Producers

Concrete is a construction material composed of cement (commonly known as Portland cement) as well as other cementitious materials such as fly ash and slag cement, aggregate (generally a coarse aggregate such as gravel, limestone, or granite, plus a fine aggregate such as sand), water, and chemical admixtures. Dry cement is so fine that 1 pound of cement contains 150 billion grains. Concrete, the final product from concrete, is used more than any other man-made material in the world.

George L. Throop Co. is a specialty ready-mix concrete producer specializing in Rapid Set® Cement and also specialty cements and grouts. We can produce from 1 to 60 cubic yards per hour, per truck.
