Concrete Testing Information

Testing tip: Test cylinders that are poorly made stored or neglected will cause headaches and may result in the need for costly hardened concrete testing all to provide the owner information proving that the actual in-place concrete is of sufficient strength and durability While this procedure is simple do not take it lightly There are a

Aggregate is the main ingredient in Portland Cement Concrete and Asphalt Concrete All aggregate used for construction purposes must be tested physically and chemically to verify its suitability for these uses Every potential production site must be tested to ensure that the m

Recycled concrete will have a higher absorption and lower specific gravity than conventional aggregates To produce good quality durable concrete containing a portion of recycled concrete aggregate often requires trial concrete mixes and close monitoring of the properties of the old recycled concrete with mix adjustments made as needed
