 Laboratory /Concrete Laboratory


   The department have main focus areas are in testing,acceptance and approval of products such as admixtures,curing compounds,pre-packaged concrete products,freeze-thaw durable aggregates and other miscellaneous products related to concrete.
   It also includes methods of improving concrete quality throughout the state.Some of the services our laboratory provides includes Compressive Strength of Cylindrical Concrete Specimens,Flexural Strength of Concrete,Length Change of Hardened
   Hydraulic-Cement Mortar and Concrete,Static Modulus of Elasticity and Poisson Ratio of Concrete in Compression,Standard Specification for Chemical Admixtures for Concrete, Specification for Anti-washout Admixtures for Concrete.Our concrete
   laboratory has also provided mix designs for the pavement industry and commercial industry.There are many tests which are conducted to check the quality of concrete as lab test on fresh concrete which consists of slump test,Compaction factor test,
   Vee-Bee test.On hardened concrete,destructive and non-destructive testing are conducted.Non-destructive tesing involves Rebound Hammer test,Ultrasonic pulse velocity test.
