Each specimen for testing was crushed into particles with a size ranging from 8 to 10 mm, which were then vacuum-dried at 25 °C for 12 h. Afterward, sampling was performed on each specimen. Pore structure testing was conducted on an AUTOPOREIV 9500 mercury porosimeter (pore size measurement range: 360 μm–5.5 nm) manufactured by Micromeritics (Norcross, GA, USA). The instrument and data processing software are shown in Figure 2 . Each collected specimen was fixed and sprayed with gold, and then, its micromorphology was analyzed by using a scanning electron microscope (FEI Quanta200, FEI, HL, USA).
Autoporeiv 9500 mercury porosimeter
Manufactured by Micromeritics
Sourced in United States
The AUTOPOREIV 9500 is a mercury porosimeter designed to measure the pore size distribution and porosity of a wide range of materials. It utilizes the principle of mercury intrusion to determine the pore structure characteristics of the sample. The instrument is capable of measuring pore sizes ranging from 0.003 to 360 micrometers.

The Mercury Intrusion Porosimetry (MIP) method was used to determine the porosity and pore size distribution of MRAC. The test instrument was the AutoPore IV 9500 Mercury Porosimeter (Micromeritics, Dr Norcross, GA, USA) by the National Key Laboratory of Chemical Engineering, Zhejiang University. The samples near the center area of MRAC were broken into small fragments after the compressive strength test and dried before the MIP test.

The morphology was confirmed using a field emission scanning electron microscopy at 10 kV (Tescan Mira-3 FEG, Brno, Czech Republic) and transmission electron microscopy (FEI, Tecnai G2-20, Hillsboro, OR, USA). A particle size analyzer (Malvern, Zetasizer Nano-ZS, Worcestershire, United Kingdom) was used to determine the silica particle size and zeta potential. The FT-IR spectra were recorded on Alpha-P (Bruker, Ettlingen, Germany). The XRD patterns were collected using an Ultima IV with Cu Kα radiation (Rigaku, Tokyo, Japan). The BET analyses were performed with an ASAP 2020 (Micromeritics, Gwinnett County, GA, USA) using the N2 adsorption–desorption isotherms. The pore size and distribution in the porous carbon was analyzed with an AutoPore IV 9500 mercury porosimeter at room temperature (Micromeritics, Gwinnett County, GA, USA). The XPS data were obtained using an Axis Nova (KRATOS, Tokyo, Japan) with monochromatic Al-Kα X-ray source under 10-8 Torr vacuum analysis chamber. The ICP-MS was used to analyze and confirm the cesium concentration in solution (iCAP RQ, Thermo Fisher Scientific, Waltham, MA, USA).

Sample mineralogy was determined on a Bruker AXS D8 X-ray powder diffractometer (Bruker Corporation, Madrid, Spain) fitted with a 3 kW (Cu Kα) copper anode and a wolfram cathode X-ray generator. The scans were recorded between 2θ angles of 5° to 60° at a rate of 2°/min. The voltage generator tube operated at a standard 40 kV and 30 mA [34 (link)].
The materials were characterised on a Thermo Scientific Nicolet 600 Fourier transform infrared spectrometer (Thermo Scientific Corporation, Madrid, Spain) featuring a spectral resolution of 4 cm−1 across a range of 4000–500 cm−1 [34 (link)].
The Hitachi S4800 electron microscope that was used to study the morphology of the 180 days blended cements exposed to the aggressive medium was coupled to a Bruker Nano XFlash 5030 silicon drift detector (Micromeritics Instrument Corp., Aachen, Germany) for EDX determination of the chemical composition of the samples [34 (link)].
Porosity was quantified on a Micromeritics Autopore IV 9500 mercury porosimeter (Norcross, GA, United States) designed to measure pore diameters of 0.006 µm to 175 μm and operate at pressures of up to 33,000 psi (227.5 MPa) [35 ].
Mechanical strength was found on an Ibertest Autotest 200/10-SW test frame that was fitted with an adapter for 1 × 1 × 6 cm3 specimens [34 (link)].

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.
