Abstract: The present work investigates the microstructural evolution process of concrete under chemical attack by magnesium sulfate solution or a composite solution (sodium sulfate and magnesium chloride), salt crystallization ...

Abstract: This paper is based on the basic mechanical properties and volume deformation test, as well as the characterization of hydration products and microstructure properties such as x-ray diffraction (XRD), scanning electron ...

Abstract: A new type of material, magnesium oxysulfate cement (MOSC), has attracted widespread attention as an environmentally friendly and low-energy inorganic green cementitious material due to its outstanding performance. In this ...

Abstract: To study the durability of magnesium oxychloride cement (MOC) in practical applications, samples from 6 to 80 years in different regions of China, including both north and south China, were collected. Phase composition and ...

Abstract: Split Hopkinson pressure bar (SHPB) with 75-mm diameter is used to conduct dynamic impact compression tests on different strength grades of basic magnesium sulfate cement-coral aggregate concrete (BMSC-CAC). The failure ...

Abstract: In this paper, the hydration reaction and properties of magnesium oxysulfate (MOS) cement modified with ammonium citrate tribasic are discussed and compared with MOS cement without chemical additives. The hydration reaction ...
