SSCND at 90%, 80%, 70%, 60%, or 50% was premixed with 10%, 20%, 30%, 40%, or 50% of cement, respectively, for 30 s, according to GB/T17671-1999 “cement mortar strength testing method (ISO) made of cement mortar specimen”, followed by demolding after 24 h standard curing with the mold size of 20 mm × 20 mm × 20 mm, at 23 ± 1 °C and 90% humidity [32 (link)]. The specimen was continuously cured under standard conditions for 28 days.
The strength tests were conducted using an electrohydraulic servo pressure test machine under microcomputer control manufactured by Changchun New Testing Machine Co., LTD. (Changchun, China) The main technical parameters included (i) high vacuum mode at resolutions of 1.0 nm-15 kV (TLD-SE, FEI company, Hillsboro, OR, USA), 1.4 nm-1 kV (TLD-SE); (ii) low vacuum mode at resolutions of 1.5 nm-10 kV (HelixTM detector, FEI company, Hillsboro, OR, USA), 1.8 nm-3 kV (HelixTM detector), and (iii) landing voltage of 50~30 kV. The morphological observation was made using the Nova NanoSEM50 series of ultra-high resolution scanning electron microscopy produced by FEI company (Hillsboro, OR, USA). X-ray diffraction (XRD) analyses were performed with CuKα radiation under 40 kV and 100 mA and a scanning speed at 8°/min.

The morphologies were observed on scanning electron microscope (SEM, FEI Nova NanoSEM 50) with an accelerating voltage of 15 kV and field-emission transmission electron microscopy (TEM, FEI Tecnai G2 F30). Fourier transform infrared (FTIR) spectra were collected using Nicolet IS10 FTIR spectrometer. The Raman spectra were performed on Renishaw inVia Raman spectrometer with He–Ne laser excited at 632.8 nm. X-ray photoelectron spectroscopy (XPS) was conducted on Thermo ESCALAB 250Xi with Al Kα excitation radiation. X-ray diffraction patterns were carried out using a Bruker D8 advance device with a 1.54 Å Cu Kα radiation source. Differential scanning calorimetry (DSC) was performed by a DSC Q200 instrument, and thermogravimetric analysis (TGA) data were collected on a NETZSCH STA 449 F3 instrument with N₂ atmosphere at a heating/cooling rate of 10 °C min⁻¹. Tensile, flexural, and impact tests were tested on the Instron mechanical testing machine, according to the ISO527-1, ISO178, and ISO180 respectively. The friction and wear properties were evaluated on a universal tribotester (GMP-30, Jinan Hengxu Tribological Testing Technology Co. Ltd., China). Sliding was performed at ambient temperature for 2 h at a sliding speed of 0.419 m s⁻¹ with a load of 196 N. Before each test, the steel ring and samples were all cleaned with acetone.

Surface/cross-sectional morphologies of the samples were measured on a scanning electron microscope (SEM, FEI Nova NanoSEM 50). X-Ray Diffraction (XRD) patterns were recorded on a Smartlab X-ray diffractometer (Cu K_α, λ = 1.5406 Å, Rigaku, Japan). The samples were placed onto the silicon sample holder and sealed by polyimide film. Thermogravimetric (TG) curves were measured on a TG analyzer (NETZSCH, STA449F3 Jupiter). Compositions of the samples were investigated by FTIR spectroscopy (Perkin Elmer).

X-ray diffraction (XRD, D8 Advance with CuKα, Bruker, Karlsruhe, Germany) was conducted to identify the crystalline phases present in the samples. Experiments were performed in the 2θ range between 5° and 80°. Fourier-transform infrared spectroscopy (FTIR, EQUINOX55, Bruker, Karlsruhe, Germany) was used to determine the chemical bonds and functional groups of the hydration products. The microstructure of these hydration products was analyzed by scanning electron microscopy (SEM, Nova NanoSEM-50, FEI Company, Hillsboro, OR, USA). The pore structures of the samples were analyzed by mercury intrusion porosimetry (MIP, AutoPore IV9500, McMurray Instruments, Atlanta, GA, USA).

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
