Construction Diagnostic Centre (CDC) is a consultancy & a construction material testing laboratory offering Non Destructive / Material  Testing ( NDT ), Quality Control, & Repair / Rehabilitation Consultancy services. CDC has been a pioneer in the field of NDT as well as Repair & Rehabilitation Consultancy in Pune and Western Maharashtra, India since 1993. An offshoot of a parent company viz 'Ranade Consultants', a firm established in 1960, CDC draws on its vast and rich experience in Structural / RCC / Project Management & Architectural consultancy.

 

CDC is the only firm offering all civil engineering-related Consultancy & Testing services under one roof. It boasts of cutting edge technology and sound infra-structure. CDC's Retro-fitting Clinic is approved by CIDC.  CDC Laboratory is  NABL  ( ISO - 17025 )  accredited Lab

 

CDC is located in the heart of Pune city, India with an office and lab set-up covering more than 3000 Sqft. of built-up area.

The laboratory is furnished with NDT and construction material testing equipments, which can support both in-house experimental studies and field evaluation studies while the office is equipped with various structural analysis and CAD software.

 

Rebound Hammer Test	Ultrasonic Pulse Velocity Test	Core Test
This is the most common method adopted for checking strength of concrete since 1940. The test is based on the principle that the rebound of an elastic mass depends on the hardness of the surface against which mass strikes. The plunger Read More ..	This is one of the most commonly used methods, in which the ultrasonic pulses are transmitted through the concrete. In solids, the particles can oscillate along the direction of sound propagation as longitudinal waves, or the oscillations can be Read More	This is one of the very reliable tests adopted for checking the compressive strength of the ‘In situ concrete”. Other physical properties such as density, water absorption can also be measured from the core concrete. Read More
Chloride Determination Test	Carbonation Test	Rebar Locator & bar sizer
The excessive amount of chloride in concrete is a great potential corrosion of the embedded reinforcement. The small quantity may be present in concrete , but chlorides may increase due to use of creek sand, saline air, seawater and Read More	CO2 present in the atmosphere reacts with the hydrated cement minerals to reduce the alkalinity of the concrete and increase the risk of reinforcement of  corrosion. Carbonation of concrete results in increase in strength and reduction Read More	The reinforcement bar is detected by magnetising it and inducing a circulating “ eddy current” in it. After the end of the pulse, the eddy current dies away, creating a weaker magnetic field as an echo of the initial pulse. The strength Read More
