Aggregate Testing


BMRTD is capable of performing all kinds of aggregate and rock testing which will be used in different construction activities. Both chemical and physical testing can be performed by BMRTD laboratories.




Automatic Sieve Shaker for sieve analysis of aggregate




Oven drying of aggregates for Water absorption test



Point load apparatus for testing rock specimens


Aggregate Impact Value Test of coarse aggregate

Following Aggregate testing services can be received from BMRTD
