- Asbestos cement flat sheets
- Bending test
- Density
- Water absorption
- Straightness and squareness
- Dimensions
- Resistance to acidified water
- Roofing sheets
- Tensile strength and modulus
- Compressive strength

Clay Bricks are vastly used in the construction industry. Presently, different types of bricks are introduced to the market in order to meet the customer's requirements. BMRTD laboratories are capable of performing quality related testing mentioned below on different bricks types.
- Compressive strength (with surface preparation)
- Water absorption
- Efflorescence
- General requirements
- Overall Dimensions
- Special burnt clay bricks (C/S and W/A) with capping (rate to be decided depending on sample preparation required)
- Compressive strength for one brick with surface preparation
- Erosion resistance
- Acid resistance
- Wetting Expansion (SLS 855)

Mostly the fine aggregates consist of natural sand or crushed stone particles that are 0.25” or smaller in size. The BMRTD conducts various kinds of testing on fine aggregates as mentioned below. All these tests are carefully analyzed by professionals.
- Grading including material finer than 63/75 µm
- Organic impurities
- Specific gravity, water absorption & moisture content
- Deleterious material (<75 mm + CL friable particles)
- Soundness as per BS (10 – 14 mm size)
- Soundness as per ASTM
- Stiffening time, humus content and light weight organic contaminants & comparative strength (BSEN 1744-1)
