Laboratory Testing — Celtest

Aggregates Celtest’s aggregate laboratory offers an extensive range of physical, mechanical and chemical tests on natural aggregate, manufactured aggregate & recycled aggregateUtilization of cement treated recycled concrete aggregates ,If recycled concrete aggregates can be reused as base or subbase materials, it will greatly alleviate the demand and extend the service life of the dumping facilities To carry out these objectives, laboratory tests such as compaction proctor test, CBR, plate loading test, unconfined compressive test, and tensile strength are achieved Many mechanical properties are obtained such as mixtures INVESTIGATION ON CHARACTERISTICS AND PERFORMANCE,investigation on characteristics and performance of recycled concrete aggregates as granular materials for unbound pavements by shiran pradeep jayakody
