“…The author thinks that no or very little number of studies on the use of nano-VS as cement replacement can be found in literature. Volcanic scoria cones exist in large numbers around the world, such as in Syria, Turkey, Iran and others [1][2][3][4][5][6][7][8][9][10]. One may find more details on the use of VS as a substitute for Portland cement, in the chapter recently published by the author [11].…”

The objective of this study is to investigate the efficiency of volcanic scoria when added to the concrete binder at a nano-scale. Nano volcanic scoria (nano-VS) was obtained by grinding a local volcanic scoria for 6 h. Twenty-four concrete mixes with four w/b ratios (0.4, 0.5, 0.6 and 0.7) and six-replacement levels of nano-VS (0%, 1%, 2%, 3%, 4%, and 5%) have been produced. The investigated concrete properties were the compressive strength, the water penetration depth, the concrete porosity and the chloride ion permeability. Workability of fresh concrete mixes has been also determined. The efficiency factor (k) of nano-VS in terms of compressive strength was calculated using the Bolomey equation. Durability indicators have been used to globally evaluate the behavior of nano-VS-based binder concrete versus control concrete. The results revealed that the efficiency factor (k) decreased to some extent when the nano-VS content was bigger than 4%. The calculated durability indicators showed that the nano-VS contents of 3% and 4% had approximately the highest indicators values. These indicators would be helpful for concrete mix designers. Some correlations between the investigated properties were derived from the analyzed data. The modification of the microstructure of nano-VS-based cement paste has been observed, as well.

This paper has experimentally measured volcanic tufa electrical conductance. The calculations are carried out in accordance with the potential of cyclic voltammetry in a constant state. The cyclic voltammograms nanoelectrode platinum prepared electrochemically were examined in the range -0.2 to 1.2 V vs. AgCl [Cl-]:1.0 M in the presence and absence of volcanic tuff in the aqueous solution of 1.0 M HCl. The cyclic voltammetry studies show that the Nano platinum film suffers degradation when the potential exceeds +0.85 V, and below this potential, it is quite stable. The redox reaction of the electrode is reversible. The nanoparticle platinum synthesized at low temperature and high acid concentration exhibits higher electronic conductivities. It has been observed that, relative to area under the peak aggregate tests, the use of volcanic concrete was showing a large increase in electrical conductivity. It was shown that with cyclic voltammetry, three well-defined anode peak could be achieved at a power of 0.0, 0.4 and 0.6 V versus Ag/AgCl.

“…Due to its low density, porous structure, high surface area, and low cost, volcanic tuff has different applications in many fields, such as concretes, mortars, building components, and wastewater treatment. [13][14][15][16] Despite the potential usability of volcanic tuff, its accumulation causes environmental and storage problems. These problems can be minimized with the proper evaluation of raw and treated volcanic tuff.…”

BackgroundGreenhouse gases, especially CO2, are primary factors for global warming and CO2 emissions continue to increase annually. Many legislations and agreements have been made to decrease, or at least stabilize, CO2 concentrations in the atmosphere. Moreover, promising CO2 capture technologies, such as adsorption using solid sorbents, have been developed and shown high CO2 adsorption capacity.ResultsVolcanic tuff, a natural pozzolanic material, was evaluated as a solid CO2 adsorbent in this study. Following pre‐treatment of the volcanic tuff with HCl solution, CO2 adsorption experiments were conducted by thermogravimetric analysis (TGA). Diamine functionalization of the volcanic tuff was carried out using amine based compounds with different chain lengths, including ethylenediamine, 1,4‐diaminobutane and 1,6‐diaminohexane. The CO2 adsorption capacity of the volcanic tuff was significantly enhanced in the presence of 1,6‐diaminohexane. Maximum CO2 adsorption capacity was determined to be 42.94 mg g−1 with 70 wt% 1,6‐diaminohexane loading. The CO2 adsorption capacity of the 1,6‐diaminohexane functionalized volcanic tuff decreased with increasing temperature, which was an indication of exothermic adsorption. Adsorption–desorption cycles revealed that the 1,6‐diaminohexane functionalized volcanic tuff was a reusable CO2 adsorbent with high stability.ConclusionThe results show that the low cost, eco‐friendly, and highly stable diamine functionalized volcanic tuff can be considered a promising adsorbent for CO2 capture. © 2023 Society of Chemical Industry (SCI).
