harvesting practices of potato is one of the most difficult, troublesome and sensitive stages. potatoes enter the machine with huge amounts of clod and stones: in the meantime separation of potato some stone and clod, which are the same size as of that the potatoes, shall be confide red a major problem. many methods of study by investigators are based on physical properties of potato, stone and...

Rapid increase in construction activities leads to active shortage of conventional construction materials due to various regions. Concrete is most widely used construction material. Cement, sand & granite stone are the constituents of the concrete. Researches were researching for cheaper materials that can be used as substitute for these materials. In this context an experimental study was carr...

Changing the water-to-cement ratio is one of major ways to develop cement slurry with different densities, which in turn will greatly affect pore structure and mechanical properties slurry. In current study, hydration model HYMOSTRUC3D was used investigate effects (w/c) (0.40, 0.44, 0.50) on evolution strength development The microstructure stone characterized via scanning electron microscope (...

There is an on-going debate about the strength and durability of different brands cements used for construction in Ghana. This has raised doubts on quality performance cements. Concrete a composite material made aggregates such as sand stone that are mixed uniformly required proportion together with water it to achieve desired its development. Cement important ingredient binds other building ma...

In this study, the researchers investigated the potential use of locally available waste materials from the lime stone quarry and the granite industry as a partial replacement of cement. Quarry sites and granite industry in the eastern province of Saudi Arabia produces tons of powder wastes in the form of quarry dust (QD) and granite sludge (GS), respectively, causing serious environmental prob...

This paper investigates the effect of a magnetic field on grinding processes Portland cement and axial tensile strength stone. It was found that dispersion composition is affected by in two modes. Moreover, without has subtle modes within small particles (0.1–0.4 microns). The with demonstrates an increase mode area decrease large (more than 1.6 microns), processing time. In this work, previous...

Within the framework of these studies, issues related to modification composition heavy concrete based on a polydisperse binder with complex modifier and its influence formation structure properties cement stone, as well hardened concrete, are considered. The purpose study is substantiate possibility obtaining effective for irrigation drainage construction improved indicators operational in ter...
