The open porosity of the sample was assessed by the Mercury Intrusion Porosimetry (MIP) method using Poremaster 60GT (Quantachrome Instruments, Boynton Beach, FL, USA) device with a maximum applied pressure of mercury at the level of 414 MPa.
Poremaster 60gt
Manufactured by Anton Paar
Sourced in United States
The PoreMaster 60GT is a gas adsorption analyzer used for the measurement of surface area and pore size distribution of solid materials. It utilizes the principle of gas adsorption to determine the physical properties of the sample.

The textural properties of the samples that presented a higher foaming effect were determined by Mercury Intrusion Porosimetry (PoreMaster 60GT, Quantachrome Instruments, Florida, USA). The porosimetry measurements were conducted using an equilibration time of 10 s, the pressure in the vessel was increased to 50 psia and then gradually brought down to atmospheric pressure.

Information on sample porosity and pore size distribution was obtained by mercury porosimetry using the Poremaster-60 GT (Quantachrome Instruments, Boyton Beach, FL, USA) within a pressure range between 5.395 KPa and 410,785.062 KPa, which corresponds to a range of pore diameters between 300 μm and 0.0035 μm.

Mercury injection capillary pressure (MICP) analysis was performed on 1 to 2 g of crushed rock using a Quantachrome Instruments PoreMaster 60GT. The measurement consisted of low-pressure analysis up to 50 psi and high-pressure analysis up to 60,000 psi for pore throat size distribution and pore volume estimation to a lower pore throat diameter limit of 3.6 nm.
Low pressure N2 gas adsorption analysis was performed on approximately 1 g of crushed rock using a Microtrac MRB BELSORP MAX II instrument. Before analysis, samples were heated at 100 °C for at least 4 h under diminished pressure. Measurement temperatures were kept to 77 K. Specific surface area and pore volume were evaluated using BET analysis. Pore size distribution was simulated by grand canonical Monte Carlo (GCMC).

The mercury intrusion porosimetry technique allows getting information on the pore structure of materials [45 (link),46 (link),47 (link)]. In this work, the porosimeter used for performing this technique was a Poremaster-60 GT model of Quantachrome Instruments (Boynton Beach, FL, USA). The tested samples were dried in an oven at 50°C for 48 h before the porosimetry test. In this work, the total porosity and the pore size distributions determined with this technique were analyzed. For the pore size distributions, it was considered the following pore size ranges: <10 nm, 10–100 nm, 100 nm to 1μm, 1–10μm, 10 μm to 0.1 mm, and >0.1 mm [48 ,49 (link)]. Two measurements were made on each binder at the corresponding testing ages. Pieces taken from cylindrical specimens with 6 cm height and 5 cm diameter were tested.

A SEM image of the freeze-dried
sample was taken on a Hitachi S-4800 microscope, as described previously.53 (link) XRD sample characterizations were performed
on a Bruker D8 ADVANCE diffractometer. Diffraction patterns were obtained
at diffraction angles between 10 and 60° at room temperature.
EA for silicium in each sample was tested with Agilent 7700×
inductively coupled plasma–mass spectrometry (Agilent Technologies,
USA) after dissolving with HF. EA for carbon (C), hydrogen (H), nitrogen
(N), and oxygen (O) was implemented using the Elemental Analyzer EA3000
(Euro Vector, Italy). The hydrophilicity or hydrophobicity of each
sample was evaluated by surface-contact-angle measurement between
thesessile water drop and sample surface. WCA measurement was performed
using Attension Theta Lite (Biolin Scientific, Finland). A drop of
water (20 μL) was dropped over the sample using an automatic
microsyringe, and then, static images for each surface were taken.

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.
