magnetic properties of white cement

  • Properties of NdFeB magnetic cement ScienceDirect

    Enhanced functional properties of cement pastes were achieved by introducing hard magnetic powders (NdFeB) into cement mixtures. The magnetic cement (cementitious magnet) employed a simple and inexpensive cementitious process to form complex NdFeB magnet shapes. NdFeB particles were distributed uniformly in the cement matrix. The density and compressive strength of the magnetic cement WHITE CEMENT PROPERTIES, MANUFACTURE, ,2016-4-1 · The whiteness is understandably one of the mostimportant properties of white cement. This must betaken into account already in the selection of the rawmaterials proper. White cement is made from rawmaterials with a low content of colouring elements suchas Fe, Mn, Cr and Ti. Use is made of high-gradelimestone or chalk containing less than 0.15 wt.% Fe2O3and less than 0.015 wt.% MnO, and of white clay,kaolin or by-products of its processing, and othermaterials which should not contain more than 1 wt.%FeO and 0.8 wt.% TiO2[5, 7, 8]. Gypsum, active andinert mineral additives are introduced in groundingWhite cement may be manufactured withstandardized surface-active plasticizers or hydrophobicadditives (in amounts of up to 0.5 wt.%) not impairingthe whiteness of the product. According to thewhiteness degree, white cement

    2018-8-25 · Properties: Grey Cement: White Cement: Raw Materials: Raw materials contain a high amount of Iron Oxide and Manganese Oxide. Raw materials contain a very little amount of Iron Oxide and Manganese Oxide. Fineness: Usually less fine than white cement. Usually finer than gray cement. Kiln Fuel: Coal, petroleum coke, fuel oil, natural gas.Magnetic properties of the micro-silica/cement matrix ,2008-10-1 · Samples of micro-silica/cement containing iron oxide, Fe 2 O 3, and doped with carbon-coated cobalt nanoparticles and free radical DPPH were prepared and studied by the magnetic resonance method. The concrete's main components (silica and cement) produced very complicated FMR/EPR (ferromagnetic and electron paramagnetic resonance) spectra.

  • Magnetic properties of the micro-silica/cement matrix

    The introduction of magnetic nanoparticles influenced the EPR spectrum of the free radical DPPH significantly: its intensity decreased above 260 K and increased slightly below this temperature, while the resonance field changed with decreasing temperature. This behavior may be associated with the porous state of cement and/or the reaction of the multi-component magnetic system.Melting behavior of water confined in nanopores of ,The size and distribution of pores have been studied through the melting behavior of water confined in white cement samples by 1 H nuclear magnetic resonance cryoporometry. It is found that the sample cured at 298 K shows a considerably coarser pore structure in the range of pores from 1 to 15 nm when compared with the samples cured at 278 K.
