Cement Testing
CBML has the testing facility of the physical properties of the cement. Cement is the binder material which has its role to bind the sand and aggregates once reaction starts after adding water. By the passage of time the properties will vary so it is important to monitor regularly the changes and accordingly to proceed towards relevant process. Hydraulic and non hydraulic cements are two basic types of cements.

Soil Testing
Soil due to its natural sizes and composition plays a vital role as the basic of structure. Suitable soil bears the load of the structure. The suitable soil used as back filled material and to be tested before and after work on the material.
Coarser the grain having more bearing value and finer the grain fill the voids in between. That is the reason a proper proportion of the sizes of the grains are important. Other Characteristics of soil also need to be studied.

Aggregates Testing
Aggregates are materials extracted directly from the ground in quarries or pits. They can be either sand and gravel, or hard rock.Hard rock deposits are quarried from a fresh face and broken by mechanical means into aggregate. Geologically they can be:

As aggregates, they are often referred to ascrushed rockor by their individual geological names.

Asphalt and Bitumen
Bitumen is petroleum product which is basic part of the roads and pavement structural component. Bitumen is categorized in grades based on the temperature and weather condition of the region. Asphalt is the mixture of bitumen as binding material and the aggregates and filler content and the component to assist in increasing the bearing pressure.
