Pile Dynamic Test
SRSBM Lab offers the Pile Dynamic Test of Concrete, steel Piles by complying the requirement of ASTM D 4945: 2012. It is a quick, non-destructive test to measure the mobilized compressive capacity and evaluate the bored pile's structural integrity. A high strain compressive stress wave is generated upon an impact on the pile top by a free fall guided drop-weight. The stress wave travels down to the pile toe and reflects the gauge location, where a strain gauge and accelerometer measure the force and velocity signals as a function of time.
This test method is advantageous over the conventional static load test method by reducing testing time and providing additional information such as pile integrity.
SRSBM LAB in-house setup arrangements ensure testing of more than Two bored pile per day depending on pile location
Ultra Sonic Pulse Velocity Test
An ultrasonic pulse velocity (UPV) test is an in-situ, nondestructive test to check the quality of concrete and natural rocks.
The method provides a very simple but cost effective test to evaluate quality of concrete, cracks or defects in the structure. The key to evaluation is selection of proper locations for the test and sampling to ensure good structural evaluation.
SRSBM Lab offers the precise, accurate & reliable Ultrasonic Pulse Velocity test accredited by NABL complying the requirement of IS 516 : Part 5 : Sec 1 : 2018.
Ultrasonic pulse velocity (UPV) test is used to check the quality of concrete also defects within concrete by passing electronic waves through the concrete.
Ultrasonic pulse velocity test method to has some limitation. The manual operation of the instrument requires careful attention by experienced technicians. If the surface is irregular, it is difficult to estimate the pulse velocity. The test object must be water resistant.
Rebound Hammer Test
The rebound hammer is a nondestructive testing apparatus, whereby the rebound of the spring driven mass is measured after its impact with concrete surface. The output of the rebound hammer is referred to as rebound number and are correlated with surface hardness of concrete.
SRSBM Lab offers the precise, accurate & reliable Ultrasonic Pulse Velocity test accredited by NABL complying the requirement of IS 516: Part 4: Sec 1: 2018.
This is one of the simplest and primitive test to evaluate the strength of concrete. Although results using this test vary significantly based on surface hardness, carbonation and variety of other factors, it is still preferred primarily due to its speed and ease of use. SRSBM LAB is equipped with several PROCEQ manual and digital hammers for testing a variety of concrete structures.
Half Cell Potential Test
The half-cell potential test is the only corrosion monitoring technique standardized in ASTM C876 - 15: Standard Test Method for Corrosion Potentials of Uncoated Reinforcing Steel in Concrete. It is used to determine the probability of corrosion within the rebar in reinforced concrete structures.
Oxygen concentration at the interface of the steel reinforcement and concrete affects the half-cell potential readings significantly. A decrease in oxygen concentration at the surface of the steel reinforcement will result in a more negative corrosion potential reading.
SRSBM Lab offers the precise, accurate & reliable the electrical half-cell potential of uncoated reinforcing steel accredited by NABL complying the requirement of ASTM C 876: 91
The test is used to estimate the probability of corrosion in steel reinforcement and is normally used in conjunction with other tests. The method eliminates the requirement of hacking concrete to physically view rebar condition. The readings are at times weather sensitive and require that concrete is moist before conducting the test.
Corrosion of steel reinforcement is a major factor in the deterioration of highway and bridge infrastructure and half-cell corrosion mapping can be used to detect corrosion, as well as being the first step towards its rehabilitation. It can also be used as a quality assurance tool in the repair and rehabilitation of concrete structures and as a predictor of remaining service life.

Pull Off Adhesion Test
The adhesion strength is a measure of how strong the bond between two materials is. This can be done in terms of load, stress, energy or work required to break the interphase.
Portable pull-off adhesion testers, like the PosiTest AT, measure the force required to pull a specified diameter of coating away from its substrate. This measured pull-off force provides a direct indication of the strength of adhesion between the coating and the substrate.
The adhesion of a coating or several coated sample of any paint product is measured by assessing the minimum tensile stress needed to detach or rupture the coating perpendicular to the substrate.
