1. The document discusses a study on enhancing concrete performance through the use of superplasticizer in mix design. Various tests were conducted to determine properties of materials used.
2. A concrete mix design was developed for M25 grade concrete as per IS specifications, using locally available materials like cement, fine and coarse aggregates, and Fosroc SP430 superplasticizer.
3. The mix design yielded a water-cement ratio of 0.44 and a cement content of 348 kg/m3 to achieve the target mean strength of 33.25 N/mm2 while allowing for a maximum slump of 75mm with the use of superplasticizer.
