Generally consisting of fine and coarse aggregate, cement, and water; concrete is an integral and vital construction material for both shaping and structural support. Concrete samples must be collected and tested by a licensed and accredited laboratory. Concrete testing measures the properties of a sample to help ensure the integrity of the concrete being used. Contingent to design specifications, each sample must meet a wide range of explicit criteria including strength, unit weight, temperature, air content and consistency. Our AASHTO accredited laboratory, complete with fully automated curing room and multiple compressive strength testing machines, is one of few regional labs equipped with diamond plate grinding, enabling compressive strength testing of high-strength concrete cylinders up to 30,000 PSI.
Aggregate is inert granular material such as sand, gravel, or crushed stone that, along with water and Portland cement, is an essential ingredient in concrete. For a good concrete mix, the aggregate elements must be solid, firm, clean, and devoid of chemicals to avoid deterioration of the composite material. Aggregate is divided into two distinct categories: fine and coarse. Fine aggregate generally consists of natural sand or crushed stone, whereas coarse aggregate consists of any particles greater than 0.19 inches. By evaluating the size, texture, weight, and consistency of the samples provided, our laboratory can determine if the aggregate meets the design requirements for the project.
Masonry, commonly used in walls and buildings, involves assembling structures by binding individual units together with mortar. Brick and concrete blocks are the most common types of masonry in use, including marble, granite, travertine, and limestone. Generally, masonry is exceptionally durable and substantial. Our laboratory tests material and strength of each block for suitable use.
With any construction project, it is imperative to establish that the site’s foundation can support the proposed building. Because soil varies in strength, moisture content, composition and type, soil testing is performed to determine each site’s limitations for structural support. Tests provide data evaluating the quality of the soil, assuring builders that the soil is suitable for the project. The AMAA AASHTO accredited laboratory provides the following soil testing services to instill further confidence in our clients regarding specified soil criteria:
Commonly known as pavement or blacktop, asphalt is the most widely used construction material for roadway development. The AMAA laboratory performs the following asphalt testing services to ensure the surface of our roadways, parking lots and foundations are safe for usage:
