Birla A1 Premium Cement “Concrete Xpert” – to ensure the best quality

Test to detect presence of impurities, dust and silt content in the fine aggregate ( river sand / manufactured sand). The maximum quantity of silt in sand should not exceed 8%. Fine aggregate containing more than 8% of silt should be washed so as to bring the silt content within allowable limits.

This test is used to determine if aggregate particles are to be considered flaky. Right aggregate gives high quality concrete. Aggregate influences the properties of both fresh and hardened concrete and impacts the character and performance of the concrete mix.

This test determines the elongation index of aggregates. Aggregate particles are considered elongated when their length is more than 1.8 of their nominal size. Right aggregate gives high quality concrete.

This method includes sampling and determination of the gradation of coarse aggregate (Gravel). Well graded aggregate increases the workability of the concrete and avoids honeycombing.

This method covers the sampling and determination of the particle size distribution of fine aggregates. Optimum particle size distribution increases the workability of the concrete & can avoid honeycombing.

Compressive Testing Machine is used to test the compressive strength of concrete at various ages.

The test is carried out using a mould known as a slump cone. At sites it is performed by the Birla A1 Premium Cement technical team to check the consistency of freshly made concrete. The slumped concrete takes various shapes, and according to the profile of slumped concrete, the slump is termed as true slump, shear slump or collapse slump. Only the true slump indicates concrete can be used whereas a shear or collapse slump should be corrected and the test should be repeated.

The device is used to measure the elastic properties or strength of concrete or rock, mainly surface hardness and penetration resistance.
