| Summary: | Concrete is considered as a strong and durable construction material lasting over a century. Reinforced concrete is one among the most popular materials used for construction around the world. Reinforced concrete is subjected to deterioration in harsh environments like in coastal regions. Therefore, several researchers are striving hard with their efforts towards developing a new material to overcome this problem. Invention of large construction plants and equipment around the world added to the enlarged use of construction materials which has raised the curtain to the use of additive mineral by product admixtures to improve the quality of concrete. As an outcome of the experiments and researches, cement-based concrete which meets special performance with respect to strength, durability and workability known as “HIGH PERFORMANCE CONCRETE” (HPC) is being developed. This concrete can be designed to give optimized performance characteristics for a given set of load, usage and exposure conditions consistent with the requirements of cost, service life and durability. The high-performance concrete does not require special equipment but only needs careful design and production. HPC has many advantages like lesser micro cracking than conventional concrete and improved durability characteristics. HPC is the concrete designed to give optimized performance characteristics for the given set of materials, usage and exposure conditions, consistent with requirement of cost, service life and durability.
In this paper, concrete with different grades were tested (M30 to M70) and cement is partially replaced with the ALCCOFINE at different proportions 0, 5%, 10% 15% and 20% to reduce the heat of hydration, so as to develop a durable concrete with the addition of said mineral admixture. Compression, Split tensile and Flexural tests were performed on concrete of different grades with Alccofine as admixture. Chemical admixtures were used in concretes of higher grades (beyond M50 grade) where the W/B ratio is very low (in the range of 0.28–0.35) to overcome the problem of workability. The concrete with Alccofine has shown encouraging results compared to conventional concrete. |
