DMDA method

This research investigated significant effects of steel fiber on engineering properties of high-strength concrete. The mix proportions were designed relied on the Densified Mixture Design Algorithm (DMDA) method in which fly ash (FA) had filler and pozzolanic effects.

This study uses densified mixture design algorithm (DMDA) to design the mixture proportions green mortars incorporating fly ash and ground granulated blast furnace slag (GGBFS). Three green mortar mixtures with various paste contents were designed using the DMDA method while a control cement-based mortar mixture was designed using the conventional method for comparison.

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.
