Concrete Beam Flexural Strength Testing: GTS, Inc. can provide compressive strength testing of cylinders, cubes, and cores of concrete or mortar and flexural strength testing of blocks and beams.
	Concrete Cylinder Compressive Strength Testing: GTS, Inc. can provide compressive strength testing of cylinders, cubes, and cores of concrete or mortar and flexural strength testing of blocks and beams.
	Floor Flatness Testing: The Dipstick 2272 determines the FF Flatness and FL Levelness Face Floor Profile Numbers (F-Numbers) per ASTM E1155. Using the Dipstick 2272 and ASTM E1155 is much more accurate than the traditional method of determining floor flatness with a straightedge.
	Floor Flatness Dipstick: The Dipstick 2272 determines the FF Flatness and FL Levelness Face Floor Profile Numbers (F-Numbers) per ASTM E1155. Using the Dipstick 2272 and ASTM E1155 is much more accurate than the traditional method of determining floor flatness with a straightedge.
	Concrete Time of Setting Test: The mortar penetration resistance apparatus determines the time of setting concrete by penetration resistance per ASTM C403. A representative sample of fresh concrete is sieved and the mortar is placed in a container. At regular time intervals, the resistance of the mortar to penetration is measured to estimate the initial and final setting times.
	Maturity Meter and Temperature Sensors: The IntelliRock II™ Concrete Maturity, Temperature, and Moisture Measurement System estimates concrete strength per ASTM C1074. This method requires establishing the strength-maturity relationship of the concrete mixture in the lab, recording the temperature history of the field concrete, and estimating the strength of the field concrete from the strength-maturity relationship.
	Schmidt Hammer: The Schmidt hammer is a rebound hammer that allows for estimating the compressive strength of concrete per ASTM C805. The steel hammer impacts the surface of a concrete with a steel plunger using a predetermined amount of energy and measures the distance that the hammer rebounds. This value is correlated to a compressive strength in psi.
	Sand Equivalency Testing: This test is intended to serve as a rapid field correlation test. The purpose of this test is to indicate, under standard conditions, the relative proportions of clay-like or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4) sieve.
