..., a notable reduction in deformation resistance was observed. Microstructural analysis using low-field nuclear magnetic resonance showed that prolonged water exposure increased overall porosity and promoted the conversion of gel and capillary pores into larger macropores, leading to a coarsened pore structure...

... into the effects of FPA on rheological properties, multi-scale pore structures and hydration products. The results showed that, over 500 days, drying shrinkage accounted for 37–66% of the total shrinkage in UHPC with pre-wetted FPA. The FPA reduced non-connected pores but increased the volume and size of connected...

... geopolymer applications. The use of ground granulated blast-furnace slag (GGBFS) to improve the mechanical properties and pore structure of LGC was investigated. The ultimate compressive stress of LGC containing GGBFS were analysed, as well as the variation in microscopic pore structure. Specimens of LGCs...

...Jie-jing Chen; Jin Xia; Renjie Wu; Yu Peng To study the influence of hydraulic pressure on pore structure evolution and chloride transport behaviour in concrete, the mass transport depth, chloride concentration and pore characteristics of specimens with different water/cement (w/c) ratios were...

... with catalysts and additives. The objective of this study was to investigate the characteristics and mechanism of the effect of different amounts of DPS sprayed on concrete. The water absorption, hydrophilicity, permeability, microhardness, abrasion erosion resistance and pore structure of concrete were tested...

...Liangyuan Xie; Lin Liu; Guanghui Tao This paper investigates the influence of pore structure on the chloride diffusivity of cement pastes. A quantitative relationship between pore structure parameters (i.e. pore diameter, porosity, constrictivity and tortuosity) and the diffusivity of cement paste...

...Yi Li; Jingxiong Wu To study the relationship between compressive strength and pore structure of concrete under chloride and sulfate dry–wet cycles, chloride dry–wet cycle tests, sulfate dry–wet cycle tests and cube compressive strength tests were conducted for normal concrete (C) and tailings ball...

... correlation between the permeability of chloride ions and pore structure, especially the proportion of pores larger than 50 nm of concrete. The microstructure of concrete contains a large number of pores and microcracks, which significantly affects its mechanical properties and durability (Jalal et...
