High volume mineral additive for eco-cement

This paper presents a new approach to the production of High Volume Mineral Additive (HVMA) cement. HVMA cement technology is based on the intergrinding of portland cement clinker, gypsum, mineral additives, and a special complex admixture, Supersilica. This new method increases the compressive strength of ordinary cement to 140 MPa and also permits the utilization of a high volume (up to 60%) of inexpensive indigenous mineral additives in the cement. The research results demonstrate that a high volume of natural materials (alumosilicates, limestone, sand, natural pozzolans) and industrial by-products (granulated blast furnace slag, fly ash) and waste (chemical wastes, broken glass and ceramic) can be used as mineral additives in HVMA cement. The maximum quantity of mineral additives in HVMA cement depends on the type of mineral admixtures and its desired strength/durability level. The optimization of the composition of HVMA cement allows the production of a cement with maximal strength and at minimal cost.


Micromechanical modelling of carbon nanotube reinforced composite materials with a functionally graded interphase
Taç, Vahidullah; Gürses, Ercan (SAGE Publications, 2019-12-01)
This paper introduces a new method of determining the mechanical properties of carbon nanotube-polymer composites using a multi-inclusion micromechanical model with functionally graded phases. The nanocomposite was divided into four regions of distinct mechanical properties; the carbon nanotube, the interface, the interphase and bulk polymer. The carbon nanotube and the interface were later combined into one effective fiber using a finite element model. The interphase was modelled in a functionally graded m...
Low-temperature chemical synthesis of lanthanum monoaluminate
Taspinar, E; Tas, AC (Wiley, 1997-01-01)
One of the promising candidates for ferroelectric substrate materials, lanthanum monoaluminate (LaAlO3), was successfully synthesized by two separate chemical powder preparation techniques: (i) homogeneous precipitation from aqueous solutions containing urea (CH4N2O) in the presence of nitrate salts, and (ii) self-propagating combustion synthesis from aqueous solutions containing CH4N2O and the respective nitrate salts of lanthanum and aluminum. The submicrometer, spherical-like particles of the precursors ...
High-volume natural pozzolan concrete for structural applications
Uzal, Burak; Turani, Lutfullah; Mehta, P. Kumar (2007-09-01)
This paper presents the results of preliminary studies on concrete mixtures containing high volumes of natural pozzolan-(50%- by mass of total cementitious materials) for- structural applications. Three different kinds, of natural pozzolans from. Turkish deposits were used to prepare the high-volume natural pozzolan (HVNP) concrete. mixtures. Two additional mixtures with a high-volume of low-calcium fly ash and granulated blast-furnace slag were also prepared for comparison purposes. In addition, a conventi...
Highly Efficient Room Temperature Synthesis of Silver-Doped Zinc Oxide (ZnO:Ag) Nanoparticles: Structural, Optical, and Photocatalytic Properties
Yildirim, Ozlem Altintas; Ünalan, Hüsnü Emrah; Durucan, Caner (Wiley, 2013-03-01)
Synthesis of silver-doped zinc oxide (ZnO:Ag) nanoparticles through precipitation method has been reported. The synthesis was conducted at room temperature and no subsequent thermal treatment was applied. ZnO nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), X-ray photoelectron spectroscopy (XPS), fourier transmission infrared spectroscopy (FTIR), and ultraviolet-visible (UVVis) spectroscopy. Detailed crystallographic investigation was accomplished through ...
The conductive polyaniline/poly(ethylene terephthalate) composite fabrics
Kutanis, S.; Karakisla, M.; Akbulut, Ural; Sacak, M. (Elsevier BV, 2007-01-01)
Conductive composite fabrics were prepared by chemical polymerization of aniline on poly(ethylene terephthalate) (PET) fabrics in the aqueous hydrochloride acid solutions using potassium dichromate as the oxidant. The effect of the polymerization conditions such as temperature, oxidant, aniline and hydrochloride acid concentrations was investigated on the electrical surface resistance and polyaniline (PAn) content of PAn/PET composite fabrics. The maximum PAn content and the lower electrical resistance of c...
