Capo (Cut and Pull Out) Test The Capo test measures the force needed to extract an embedded insert from a concrete mass. By using a previously established relationship, the measured ultimate Capo load is used to estimate the in place compressive strength of the concrete. The Capo test can be used to determine the following properties. 4 Compressive strength of concrete 4 Normally planned for new structures to help decide, whether critical activities such as form removal, application of post tensioning etc. can be started 4 Can be used for existing structures and surveys of matured concrete

4 Rapid Chloride Permeability Test (RCPT) This test covers the determination of the electrical conductance of concrete to provide a rapid indication of its resistance to the penetration of chloride ions. The test method is applicable to types of concrete where correlations have been established with this procedure and long-term chloride ponding procedures.

Bridge Load testing process is a component of the inspection process and consists of determining the safe load carrying capacity of structures.

5 Pile Integrity Test (PIT) The Absence of major cracks and voids on any type of concrete foundations prior to construction of the superstructure. It may also test piles integral in the structure, can be defected using PIT. It helps tp check the integrity of Pile. Core Test The core test provides the visual inspection of the interior of the concrete and direct measurement of the compressive strength. Other physical properties, such as, density, ater absorption, indirect tensile strength and expansion due to alkali-aggregate reaction can also 4 Density 4 Water Adsorption 4 Indirect Tensile Straight 4 Expatsion due to Alkali Aggregate Half Cell Potential Meter Test The severity of steel corrosion can be assured by corrosion potential. This test provide probability of corrosion activity taking place at the point where measurement by potential is taken from Half Cell. Ultrasonic Pulse Velocity This testing ensure the uniformity of concrete. It can be conducted on both existing structures & there under construction. Table: Velocity Criterion for concrete Quality Grading (IS :13311 Part I ) S.No Pulse velocity in cross probing(km/sec) Concrete Quality Grading 1. Above 4.5 Excellent to 4.5 Good to 3.5 Medium 4. Below 3.0 Doubtful Rebound Hammer It is conducted to find compressive strength of concrete by using Rebound Hammer as per IS:13311 (Part II) Aug Rebound No. & Quality of concrete. Table:- Average Rebound number and quality of concrete Average Rebound Number Quality of Concrete >40 Very good hard layer 30 to 40 Good layer 20 to 30 Fair < 20 Poor concrete 0 Delaminated
