Abstract This study explores the use of ten different fine materials to partially substitute cement, aiming reduce greenhouse gas emissions from cement production. The include two types fly ash (coarse and fine), blast furnace slag, silica fume (SF), three grades limestone powder (coarse, medium, quartz powder. physical, chemical, mineralogical properties these were analyzed, 51 pastes produced effects particle characteristics on packing density (PD) fresh paste properties. Parameters such as size distribution, specific surface area, shape examined in relation PD, flowability, rheological behavior (yield stress plastic viscosity). Both De Larrard centrifugal consolidation methods used measure PD. experimental results revealed that incorporation coarse increases PD 61.5%, while addition decreases it 55.1%. SF up 10% replacement; however, with excess content, due high fineness particles. Additionally, exhibited lowest flow spread, 112 mm (62% reference paste). Plastic viscosity area Fly can be replace by 50% without deteriorating flowability pastes.

In order to rationalize the consumption of graphite tailing sand and reduce its pollution environment—with sodium silicate being a commonly used activator for improving strength concrete composites—in this study, joint effects (SS) tail (GT) on frost resistance high-performance mortar (GT-HPM) were investigated. Experiments conducted evaluate bulk density, water absorption, compressive strength, speed sound, working performance status GT-HPM before after freezing thawing at different SS dosages GT substitution rates. The microstructural properties also analyzed by X-ray diffraction (XRD), Fourier-transform infrared spectroscopy (FT-IR), scanning electron microscopy (SEM/EDS). results showed that 4% doping improved more obviously. Moreover, with an increase in rate, mechanical increased firstly then decreased, best was obtained when rate 20%. At 6% doping, gradually decreased rate. FT-IR testing there no significant change type hydration products used, Si–O–T absorption peak average bond length GT-4 largest. promoted generation products. Microstructural analysis reaction; addition, appropriate amount pore structure HPM, resistance, provided fundamental insights subsequent comprehensive utilization sand.
