Effect of Alcofine_1206 as a Mineral Addition in Concrete Grades M-20 & M-25 Mixes
This study investigates the effect of alccofine 1206 as a mineral addition in concrete on the concrete grade M20 and M25 mixes (trial, control, and variation) were prepared.
Slump tests were performed on all concrete mixtures after 07 and 28 days, as well as flexural and splitting tensile strength tests. To test the impact of alccofine1206 on concrete, 186 cubes, cylinders, and beams were constructed. At room temperature, these concrete samples were deep cured in water. Partially replacing M20 and M25 concrete grades resulted in 15% higher slump than adding alccofine 1206. Slump was measured at 150mm with 5% alccofine and 155mm with a partial replacement of alccofine 1206 with M25 grade concrete.
When 15% alccofine 1206 was added to OPC, strength of M20 grade concrete found to be more as that of standard M25. M25 grade with 15% alccofine 1206 and M30 grade concrete with partial replacement with alccofine 1206 exhibited more than or nearly similar compressive strength when tested. Tensile strength followed the same pattern. The splitting tensile strength of M20 grade concrete containing 15% alccofine 1206 and partial replacement of OPC with alccofine 1206 was found to be more than or nearly equal to that of standard M25 grade concrete. The splitting tensile strength of M25 grade concrete containing 15% alccofine 1206 was found to be greater than or equivalent to that of M30 grade concrete containing standard alccofine 1206.
The density of M20 grade hardened concrete increased the highest when 15% alccofine 1206 was added to OPC and 15% OPC replaced with 15% alccofine 1206. Similarly, when alccofine 1206 was added to OPC or when OPC was partly replaced with alccofine 1206 at 15%, the density of M25 hardened concrete increased. Variational mixtures are stronger and more lasting than conventional mixes, for improved performance.
