Powder flow is influenced by the presence of fines contained in the bulk powder, by the particles' size distribution and by their morphological characteristics. To meet the different needs of customers, a number of sugar varieties are marketed, including the granulated white sugar, the brown raw sugars and the powdery refined sugars.
These samples are finer than the brown sugar and full particle size distribution (PSD) data can be measured by light scattering. Correlating flow properties, BFE and SE, with Dv10, Dv50, and Dv90 identifies two robust relationships (see figure 3). BFE correlates strongly with Dv10 (R2 = 0.9868), while SE correlates with Dv50 (R2 = 0.8082).

Marble waste powder is waste produced from marble industry. Adding Marble Waste Powder (MWP) gives a phenomenal strength to concrete. In this paper, the flow properties of SCC are studied with different percentage of marble waste powder. As a partial substitute for cement, a quantity of marble waste powder is added.
These wastes contribute significantly to environmental contamination in modern society. In order to achieve the requisite strength, one part marble powder is substituted for one part concrete in this operation. Marble powder is substituted in concrete in various percentages of 5%, 10%, 15%, 20%, and 25% for grade M40 concrete.
The subject of this study is centered on the strategic incorporation of recycled concrete powder (RCP), marble powder (MP), glass powder (GP), and limestone powder (LP) as viable substitutes for traditional cement, at varying rates of 25%, 30%, and 35%, with the overarching goal of augmenting sustainability in construction practices.
