Pore Structure Quantification and Fractal Characterization of MSA Mortar Based on 1H Low-Field NMR

Fractal and Fractional, Journal Year: 2024, Volume and Issue: 8(1), P. 42 - 42

Published: Jan. 9, 2024

With the gradual depletion of natural sand due to over-exploitation, alternative building materials, such as manufactured aggregate (MSA), have attracted much attention. In order interpret evolution pore structure and fractal characteristics in MSA mortar over long-term water saturation, 1H low-field nuclear magnetic resonance (LF-NMR) relaxation method was used investigate temporal five single-graded mortars synthetic-graded with small amplitudes particle size. presents a fresh rock interface characterized by scarcity pores, which significantly reduces porosity mortar. The surface-to-volume ratio (SVR) is employed for characterizing gradation. Through an analysis parameters, total porosity, gradation, connectivity, dimension mortar, correlation model between parameters SVR constructed. pores their variations are discussed under three kinds gradations, established. These results demonstrate high impermeability outstanding corrosion resistance has guiding effect on distribution engineering permeability evaluation engineering.
