Abstract(s)
The concrete workability and the compressive strength are
the principal properties of the fresh and hardened concrete,
respectively. When self-compacting properties are required,
scientific knowledge is important and appropriate models ap plied to achieve optimized compositions. Here, experimen tal data regarding to the mortars is presented. The dataset
regards to a design of experiments carried out in mor tars with commercial materials through a central compos ite design with five independent variables: Waterv/Cementv,
Superplasticyzerm/Powderv, Waterv/Powderv, Sandv/Mortarv,
FineSandv/Sandv. In total 64 mortar composition were done:
25 factorial design consisting on 32 treatment combinations
augmented by 10 axial runs plus 8 central runs, resulting in
a central composite design with 50 mortar trial mix compo sition. Beside 14 extra mixes were done to allow comparing
and validating results for the response models to be applied.
Four dependent variables were measured: the D-flow and the
t-funnel to measure the workability and the tensile strength
and the compressive at the age of 24 h to assess the me chanical properties. Since the experiments were run based in a central composite design and extra mixes were prepared,
response models can be applied to the dataset in order to
find optimized mix compositions.
