  • Effect of Phosphoric Acid and Soluble Phosphate on the . . . - MDPI
    This study investigates the effects of phosphoric acid (H3PO4), potassium dihydrogen phosphate (KH2PO4) and sodium dihydrogen phosphate (NaH2PO4) admixtures on the setting time, compressive strength and water resistance of magnesium oxychloride cement (MOC) MOC samples incorporating different admixtures are prepared, and their hydration products and microstructures are studied via X-ray
  • Alkali Activated Paste and Concrete Based on of Biomass Bottom . . . - MDPI
    When 5% or 10% of semi hydrate PG was incorporated in the system, the mechanical properties, improvement was detected Chang et al investigated the influence of phosphoric acid and gypsum on the sodium silicate-based alkali-activated slag pastes It was determined that the addition of phosphoric acid acted as a retarder
  • Acid Activation in Low-Carbon Binders: A Systematic Literature . . . - MDPI
    Geopolymers have emerged as an alternative binding material to Ordinary Portland Cement (OPC) Recently, there has been an increase in studies exploring the synthesis of these materials using acid activation rather than traditional alkaline activation This approach offers benefits such as good strength at an early age, better thermal properties, and a chemical activator that emits less carbon
  • Effect of Baghdadite Substitution on the Physicochemical . . . - MDPI
    All articles published by MDPI are made immediately available worldwide under an open access license No special permission is required to reuse all or part of the article published by MDPI, including figures and tables and primary calcium phosphates in equimolar ratios to produce stoichiometric brushite is an exothermic acid-base reaction
  • Application of Phosphogypsum in Ultra-High-Performance Concrete . . . - MDPI
    Ultra-high-performance concrete is a high-strength and durable material widely used in infrastructure, but its high cement content raises environmental concerns, particularly in terms of CO₂ emissions and resource consumption Phosphogypsum, an industrial by-product of phosphoric acid production, presents a sustainable alternative by partially replacing cement, thereby reducing cement demand
  • Properties of Cemented Filling Materials Prepared from . . . - MDPI
    All articles published by MDPI are made immediately available worldwide under an open access license Phosphogypsum (PG) is a by-product from the production of phosphoric acid, usually in the form of calcium sulfate dihydrate Roy, D M Ettringite and C-S-H Portland cement phases for waste ion immobilization: A review Waste Manag 1996
  • Calcium Orthophosphate Cements and Concretes - MDPI
    All brushite cements are set by the acid-base interaction only As DCPD can only precipitate at the solution pH < 6, the paste of brushite cement is acidic during setting [127,189] For example, during setting of a β-TCP + MCPM cement, the cement pH varies from very acidic pH values of ~ 2 5, to almost neutral pH values of ~ 6 0 Replacing
  • Materials | Free Full-Text | Effect of Phosphoric Acid and Soluble . . .
    All articles published by MDPI are made immediately available worldwide under an open access license No special permission is required to reuse all or part of the article published by MDPI, including figures and tables W Effect of Phosphoric Acid and Soluble Phosphate on the Properties of Magnesium Oxychloride Cement Materials 2024, 17
  • Effects of the Curing Regime, Acid Exposure, Alkaline Activator . . . - MDPI
    Reductions of green gas emissions and the reuse recycling of industrial byproducts are important for the mitigation of the environmental impact of the construction industry The replacement of ordinary Portland cement (OPC) is a concrete binder with industrial byproducts that possess sufficient cementitious and pozzolanic properties, such as ground granulated blast furnace slag (GBS) and fly
  • Biological and Mechanical Performance of Dual-Setting Brushite . . . - MDPI
    Brushite has a significantly lower compressive strength of up to 60 MPa and tensile strength of up to 10 MPa, making it suitable for use in less load-bearing areas, such as the face, as a bone substitute material [] However, the setting reaction of this cement is much faster than that of hydroxyapatite cements, taking only 30–60 s
  • Hydration and Strength Development of Cementitious Materials . . . - MDPI
    To rationally use low-grade phosphorous limestone as the raw materials for cement production, the influence of phosphorous introduced by fluorapatite during the clinker calcination process on the mechanical properties of cementitious materials is investigated Hydration kinetics, phase evolutions, and microstructure of cement pastes have been studied by using calorimetry, X-ray diffraction
  • Obtaining Composite Zinc Phosphate Cement with the Addition of . . .
    The feasibility of producing high-quality zinc phosphate cement based on a frit-sintered mixture of ZnO, SiO2, MgO, and Bi2O3 oxides, with the addition of phosphorous slag and an aqueous solution of orthophosphoric acid as the mixing liquid, was demonstrated The raw materials used for zinc phosphate cement preparation were investigated using various physicochemical analysis methods It was
