Chouicha PY - 2015/5/ TI - A Methodological Test to Study the Concrete Workability with the Fractal Model T2 - International Journal of Materials and Metallurgical Engineering SP - 569 EP - 576 VL - 9 SN - 1307-6892 UR - https://publications.waset.org/pdf/10002045 PU - World Academy of Science, Engineering and Technology NX - Open Science Index 100, 2015 N2 - The main parameters affecting the workability are the water content, particle size, and the total surface of the grains, as long as the mixing water begins by wetting the surface of the grains and then fills the voids between the grains to form entrapped water, the quantity of water remaining is called free water. The aim of this study is to undertake a fractal approach through the relationship between the concrete formulation parameters and workability. To develop this approach a series of concrete taken from the literature was investigated by varying formulation parameters such as G/S, the quantity of cement C and the quantity of water W. We also call another model as the model of water layer thickness and model of paste layer thickness to judge their relevance, hence the following results: the relevance of the water layer thickness model is considered as a relevant when there is a variation in the water quantity. The model of the paste layer thickness is only applicable if we considered that the paste is made with the grain value Dmax = 2.85: value from which we see a stability of the model. ER -
