Mixture design for high strength concrete

The objective of this research is to design mixture proportions for high strength concrete with controlled amount of cement and water through the application of densified mixture design algorithm (DMDA) method, which is comparable with conventional method (ACI). Cylindrical concrete specimens in size of 10 × 20 cm were prepared for compressive strength test. The effect of superplasticizer (SP) on workability of fresh concrete is also investigated. Test results indicate that the concrete specimens designed by DMDA method achieve higher compressive strength than that designed by ACI method. Additionally, the use of SP significantly increases the workability of fresh concrete.
