MAGMENT — Magnetic Concretes

Concrete never had magnetic properties until now. This is actually easy by just replacing gravel and sand by coarse and fine magnetic fillers merging the worlds of construction and electromagnetism. High permeability (up to 70) opening up a broad range of electromagnetic applications.,Effects of Static Magnetic Fields on the Physical,,This paper presents the results of an experimental study carried out to comprehend the physical, mechanical, and microstructural behavior of cement pastes subjected to static magnetic fields while hydrating and setting. The experimental methodology consisted in exposing fresh cement pastes to static magnetic fields at three different magnetic induction strengths: 19.07, 22.22, and 25.37 Gauss.What is white cement. Characteristics and fields of,,Composition and properties of white cement. Materials. Light coloring of cement is achieved by using raw materials where there are no glandular compounds or are present, but in a small amount. White cement is produced on the basis of low-iron clinker, where the content of manganese and chromium is minimized.

White Portland cement - Wikipedia

White Portland cement or white ordinary Portland cement (WOPC) is similar to ordinary, gray Portland cement in all aspects except for its high degree of whiteness. Obtaining this color requires substantial modification to the method of manufacture, and because of this, it is somewhat more expensive than the gray product. Uses. White Portland cement is used in combination with white aggregates,WHITE CEMENT - PROPERTIES, MANUFACTURE, PROSPECTS,The properties of white cement The whiteness is understandably one of the most important properties of white cement. This must be taken into account already in the selection of the raw materials proper. White cement is made from raw materials with a low content of colouring elements such as Fe, Mn, Cr and Ti. Use is made of high-grade limestone or chalk containing less than 0.15 wt.% Fe 2O3,Rheological Properties of Cement Paste with Nano-Fe3O4,,paste between parallel plates is examined by the magnetic properties of the powder as determined by a vibrating sample magnetometer.

White Portland cement - Wikipedia

Specifications. White Portland cement differs physically from gray cement only in terms of its color. Its setting behavior and strength development are essentially the same as that expected in gray cement, and it meets standard specifications such as ASTM C 150 and EN 197. In practice, because much white cement is used in pre-cast concrete products, it is commonly made to a high-early strength,An all white magnet by combination of electronic,,The system is constituted by combination of an inorganic white core with either hard or soft magnetic properties and a white light emitting MOF.
