Microwave Heating of Cordierite Ceramic Substrate for After Treatment Systems

Selective catalyst reduction is one of the most affordable and successful technologies aimed at reducing NOx emissions from diesel engines. However, the reduction process can be achieved if a certain temperature is reached for the ceramic substrate of the catalytic core. The required temperatures for catalytic reaction vary from 2500 C to 4500 C depending on the technology applied in the catalytic processes. This paper aims at presenting preliminary research in microwave cordierite heating, which is a type of magnesium aluminium silicate used as ceramic honeycomb substrate (catalyst monolith) in the after treatment system in the automotive industry. The research focused on testing the Mg2Al4Si5O18 composite material (cordierite) for different microwave heating regimes in order to establish the level of microwave power required for fast heating. This application will be subject for the further development of new MW-SCR after treatment systems in order to reduce the NOx emissions at cold start engine or low operating regimes of non-road mobile machinery engines. The ceramic composite material was heated for 5 levels of microwave power, from 600 W to 1400 W, using a 6 kW microwave generator coupled with a matching load impedance tuner, and the temperatures were recorded using an IR pyrometer.

Effects of the internal structures of monolith ceramic substrates on thermal and hydraulic properties: additive manufacturing, numerical modelling and experimental testing

Rigorous emission regulations call for more efficient passive control catalysts for exhaust gas aftertreatment without affecting the internal combustion process and CO2 emissions. Although the state-of-art ceramic honeycomb substrate designs provide high surface area and a degree of flexibility for heat and mass transfer adaptations, additional emission reduction benefits can be achieved when more flexible designs to provide effective thermal management are introduced. The conventional cordierite honeycomb substrates are manufactured by extrusion; therefore, only substrates with straight channels can be fabricated. This study aims to highlight any design limitations of conventional substrates by employing additive manufacturing as the main method of manufacturing diamond lattice structures using DLP (digital light processing) technology. Both conventional substrates and diamond lattice structures are studied numerically and experimentally for flow through resistance and temperature distribution. Numerical predictions and experimental results showed good agreement. The results show the increase of the axial temperature distribution for diamond lattice structures and a significant decrease of the pressure drop (38–45%) in comparison with the benchmark honeycomb with similar surface area.

Study on the feasibility of using monolithic catalyst in the in-situ catalytic biomass pyrolysis for syngas production

In-situ catalytic biomass pyrolysis for syngas production is a competitive technology for the recovery of energy in biomass. However, in conventional in-situ catalytic pyrolysis process, the mode of catalyst introduction makes it difficult to separate the catalyst from the char after pyrolysis, resulting in difficulty in catalyst recycling. We considered that the use of monolithic catalyst which has larger size than the biomass feedstock might solve the problem of the separation difficulty between the catalyst and char. In order to verify the feasibility of this strategy, NiO/γ-Al2O3 was respectively supported on ceramic honeycomb, metal foam, and metal wire mesh to produce three monolithic catalysts with different outer surface areas. Their catalytic performance for cattle manure pyrolysis was tested and the result revealed that compared with the granular NiO/γ-Al2O3, using monolithic catalysts with ceramic honeycomb, metal foam, and metal wire mesh carrier respectively increased the gas production by 37%, 33%, and 11%. The use of monolithic catalyst in in-situ catalytic biomass pyrolysis, not only simplified the separation process of catalyst and char, but also enhanced the catalysis performance.

Simulation and Measurement of Energetic Performance in Decentralized Regenerative Ventilation Systems

Decentralized regenerative mechanical ventilation systems have acquired relevance in recent years for the retrofit of residential buildings. While manufacturers report heat recovery efficiencies over 90%, research has shown that the efficiencies often vary between 60% and 80%. In order to better understand this mismatch, a test facility is designed and constructed for the experimental characterization and validation of regenerative heat exchanger simulation models. A ceramic honeycomb heat exchanger, typical for decentralized regenerative ventilation devices, is measured in this test facility. The experimental data are used to validate two modeling approaches: a one-dimensional model in Modelica and a computational fluid dynamics (CFD) model built in COMSOL Multiphysics®. The results show an overall acceptable thermal performance of both models, the 1D model having a much lower simulation time and, thus, being suitable for integration in building performance simulations. A test case is designed, where the importance of an appropriate thermal and hydraulic modeling of decentralized ventilation systems is investigated. Therefore, the device is integrated into a multizone building simulation case. The results show that including component-based heat recovery and fan modeling leads to 30% higher heat losses due to ventilation and 10% more fan energy consumption than when assuming constant air exchange rates with ideal heat recovery. These findings contribute to a better understanding of the behavior of a growing technology such as decentralized ventilation and confirm the need for further research on these systems.

Performance of a Diesel Particle Filter Damaged by Drilling Holes in the Filter Walls to Simulate Internal Micro-cracks

Diesel particle filter (DPF) is an effective way of reducing soot particles in the exhaust of diesel engines. The new emission regulations for non-road machineries effectively require that they are equipped with DPFs. However, these devices can be damaged and lead to an increase in the concentration at the filter outlet, which can exceed the emission limits. A study has been conducted to evaluate the impact of a micro-leak, created within a ceramic honeycomb filter, on its performance, i.e. filtration efficiency and pressure drop. The measurements carried out, as well as a modelling of the leak phenomenon, show that the simple measurement of the pressure drop is insufficient for the detection of these micro-leaks, which result in a significant drop in efficiency, all the more important as the flow resistance and efficiency of the filtering media is high.

In Ukrainian

Methanol carbonylation (MC) to produce acetic acid is a strategically important large-scale process (Monsanto and BP Chemicals Cativa TM ), which is carried out under high pressure in the liquid phase using Rh(Ir) catalysts and extremely toxic halide cocatalysts/promoters. In addition to acetic acid, methyl acetate is also an industrially important product of MC. The halogen-free heterogeneous-catalytic process of methanol carbonylation in the vapor phase using catalysts containing no noble metal, in particular Ni-based on carbon supports, provides a number of advantages over homogeneous systems, including the possibility of multifold use of catalytic compositions. Important factors that cause the formation of acetyls are the textural, acidic properties of the catalysts, the presence of modifying/promoting additives in their composition. Nickel and copper chlorides supported on activated carbon were shown in [Catal. Today. 2004. 93–95:451] to catalyze the vapor-phase MC process producing methyl acetate at ambient pressure in the absence of alkyl halides in the gas reaction mixture. This paper presents the results of the studying the effect of supports (activated carbon of BAU-A (AC), SKT, SUGS grades; structured – cordierite, Al 2 O 3 /cordierite) of copper-nickel chloride catalysts, characterized by the low-temperature ad/desorption, XRD, TPD-NH 3 , TPR-H 2 techniques; modifying additives of tin on the production of methyl acetate in the halide-free vapor-phase methanol carbonylation under ambient pressure. It is shown that the yield 18 % of the target product in the presence of a catalyst on activated carbon of the BAU-A grade significantly exceeds the Y MeOAc 3 and 7 % indices for NiCl 2 -CuCl 2 compositions on SKT and SUGS, respectively. The formation of methyl acetate on NiCl 2 -CuCl 2 /AC is facilitated by the optimal combination of the porous structure characteristics (the presence of mesopores with an average diameter of ~ 7 nm) and the surface acidity of the specified catalyst, which are favorable for the activation of reagent molecules of the MC process. Methyl acetate yield of 15 % in the presence of NiCl 2 -CuCl 2 compositions on ceramic honeycomb supports (synthetic cordierite) with a specific surface area ~ 0.5 m 2 /g, commensurate at 355–360 °C with Y MeOAc for NiCl 2 -CuCl 2 /AC, is achieved due to more efficient mass transfer and heat removal in the exothermic reaction of methanol carbonylation compared to highly porous catalysts. The conclusion is substantiated that the modification of the NiCl 2 /AC sample with tin additives provides an increase in the yield of the target product from 2 to 11 %, which may be caused by the formation of intermetallic phase crystallites Ni 3 Sn within NiCl 2 -Sn/AC (identified by XRD) under conditions of catalysis – adsorption/activation sites of CO molecules.

Nonthermal plasma in practical-scale honeycomb catalysts for the removal of toluene

Nonthermal plasma combined with a practical-scale honeycomb catalyst of 5.0 cm in height and 9.3 cm in diameter was investigated for the removal of toluene. The creation of plasma in the honeycomb catalyst greatly depended on the humidity of the feed gas and the presence of metals on the honeycomb surface. Compared to the bare ceramic honeycomb, the metal-loaded one gave higher toluene removal efficiency because the decomposition of toluene by the plasma-generated reactive species occurred not only homogeneously in the gas phase but also heterogeneously on the catalyst surface. The present plasma-catalytic reactor was able to successfully remove about 80% of dilute toluene (15 ppm in air) at a large flow rate of 60 L/min with a specific energy input of 58 J/L. The honeycomb-based plasma-catalytic reactor system is promising for practical applications since it can overcome such problems as high-pressure drop and difficulty in scale-up encountered in packed-bed reactors.

Experimental investigation on bending behaviour of ZrO2 honeycomb sandwich structures prepared by DLP stereolithography

The ceramic honeycomb sandwich structures of 3 mol% yttria-stabilized tetragonal ZrO2 (3Y-TZP) material were fabricated by an additive manufacturing technique based on the digital light processing (DLP) system. The bending behaviour of hexagonal and square honeycomb sandwich structures was investigated with three-point bending test. The effects of geometric parameters, including the thickness of the face-sheet, the height of the cell, the thickness of the cell wall and the size of the cell, were studied through experiments carefully. The results illustrated that the bending strength of the ceramic honeycomb sandwich structure can reach 170 MPa at a relative density of 41.72%. The geometric parameters of the honeycomb core were more critical than the sandwich face-sheet. The cell size, cell wall thickness and cell height were found to be the preferred geometric parameter for justifying the bending resistance performance of the ceramic sandwich panel. Square honeycomb demonstrated better bending performance than the hexagonal honeycomb. This study provides a new basis for further studies on the ceramic lightweight structures.

3D printing of high surface area ceramic honeycombs substrates and comparative evaluation for treatment of sewage in Phytorid application

Substrates properties play an important role in immobilization of bio-organisms and hence in optimizing design of the bioreactor to maximize the performance. Highly flexible 3D printing process based on virtual Computer Aided Design (CAD) is used for producing honeycomb substrates with desired properties. Clay based honeycomb with square, triangular and hexagonal configurations are 3D printed in order to achieve substrates with pre-designed geometrical surface areas. Laboratory reactors were fabricated with engineered properties using 3D printed honeycombs and a combination of honeycombs and commonly used stones for performance evaluation. Additionally, reactor based on commonly used gravel stones also fabricated for sake of comparison of performance. In order to elucidate the performance, sewage mix was fed into the reactors and the space velocity of all the three reactors were maintained at 0.041 h−1. The sewage before and after treatment was tested for the performance markers such as pH, TSS, BOD and COD. Treated water met the stipulated standards prescribed by American Public Health Association with respect to all parameters studied. Though the difference in the performance of the reactors was marginal, with honeycombs a substantial reduction in the weight of the reactor can be accrued along with high mass transfer due to low pressure drop which can be attributed to the inherent higher surface to volume ratio. Further, by engineering the surface porosity of the honeycombs, it is possible reduce TSS as demonstrated in this study. These advantages offer flexibility in scaling up the reactors for larger capacities for de-centralized requirements.

Polyoxometallate functionalizing CeO2via redox-etching precipitation to synergistically catalyze oxidation of gaseous chlorinated pollutants: From lab to practice

Redox etching-precipitation is universally applied to homogeneously functionalize CeO2 with various acids including polyoxometallates (POMs) and liquid acids. Acid functionalization causes changes of physiochemical natures concerning reducibility, surface oxygen species as well as acidic sites. Among acids, because of POMs featuring superacid nature and Brønsted acid-induced antipoisoning effect, POMs-grafting can obviously facilitate catalytic oxidation of chlorinated organic contaminants (e.g. chlorobenzene, dichloromethane and trichloromethane) over CeO2-based catalysts. Through comparison, CeO2 nanorod functionalized with 5% silicotungstic acid (5% HSiW/r-CeO2) is screened out as an optimal catalyst, which exhibits a remarkable activity and long-term stability to catalyze oxidation of chlorinated pollutants at realistic condition. Moreover, the monolithic catalyst test pronounces that the practice application can be satisfied by loading 5% HSiW/r-CeO2 on honeycomb ceramics. With combination of structure and performance, the synergic effect of POMs functionalized CeO2 on catalytic oxidation of chlorinated pollutants is clearly refined.

Thermochemical storage performance of a packed bed of calcium hydroxide composite with a silicon-based ceramic honeycomb support

The thermal decomposition of calcium hydroxide (Ca(OH)2) into calcium oxide (CaO) and water vapor has been suggested as a reversible gas–solid reaction suitable for thermochemical energy storage. This study aims to develop a composite material to enhance the heat transfer in a reaction bed. We focus on a novel material using CaO/Ca(OH)2 and a ceramic honeycomb support composed of silicon carbide and silicon. A laboratory-scale evaluation of the thermochemical storage performance of the composite using honeycomb support has not been sufficiently reported in the literature. In this study, a 100 W-scale packed bed reactor was used to evaluate the performance of the composite. We found that the composite had a volumetric energy density of 0.76 MJ L-bed−1 and exhibited a heat output rate of 1.6 kW L-bed−1 (for the first 5 min at the highest hydration pressure of 85 kPa), which was 1.8 times higher than the heat output rate previously reported for a pure Ca(OH)2 pellet bed. The composite also retained its high reactivity during repetitive reactions. Therefore, it was concluded that the composite using the ceramic honeycomb support is practically more useful for thermochemical energy storage than conventional pure CaO/Ca(OH)2 materials.

MnOx-CuOx cordierite catalyst for selective catalytic oxidation of the NO at low temperature.

Low-value solid waste cordierite honeycomb ceramics were used as carrier of SCO denitration catalyst, and the active component was supported by the impregnation method to improve the performance of the catalyst. Firstly, the effect of calcination conditions on the denitration performance of the Mn-loaded cordierite catalyst was studied for the cordierite-loaded active component MnOX. Secondly, the preferred catalyst was reloaded with another active component to further improve its denitration performance; the bimetal ratios were affected by the denitration performance, which was, finally, characterized by XRD, XPS, and SEM. The result shows the following: (1) Mn-loaded cordierite prepared at 450°C for 3h has a good denitration effect; (2) the MnOX-CuOX/CR catalyst is superior to MnOX-FeOX/CR, MnOX-CoOX/CR, and MnOX-CeOX/CR; (3) the MnO2 crystal form in the single metal-supported catalyst plays a major role, and Cu2Mn3O8 in the bimetallic catalyst affects the performance and activity of the catalyst.

Numerical and experimental study on hydrogen production via dimethyl ether steam reforming

This work presents the characteristics of catalytic dimethyl ether (DME)/steam reforming based on a Cu–Zn/γ-Al2O3 catalyst for hydrogen production. A kinetic model for a reformer that operates at low temperature (200 °C–500 °C) is simulated using COMSOL 5.2 software. Experimental verification is performed to examine the critical parameters for the reforming process. During the experiment, superior Cu–Zn/γ-Al2O3catalysts are manufactured using the sol-gel method, and ceramic honeycombs coated with this catalyst (1.77 g on each honeycomb, five honeycombs in the reactor) are utilized as catalyst bed in the reformer to enhance performance. The steam, DME mass ratio is stabilized at 3:1 using a mass flow controller (MFC) and a generator. The hydrogen production rate can be significantly affected depending on the reactant's mass flow rate and temperature. And the maximum hydrogen yield can reach 90% at 400 °C. Maximum 8% error for the hydrogen yield is achieved between modeling and experimental results. These experiments can be further explored for directly feeding hydrogen to proton exchange membrane fuel cell (PEMFC) under the load variations.

Thermal shock resistance behavior of auxetic ceramic honeycombs with a central crack or an edge crack

In this paper, the thermal shock resistance of an auxetic ceramic honeycomb plate is studied based on the fracture mechanics concept for the cases of a central crack or an edge crack. The transient temperature field and transient thermal stress field are obtained for both auxetic and non-auxetic structures. The relationship between the thermal stress intensity factor (TSIF) and the internal cell angle, crack length and time is determined and the critical temperature for the initiation of crack propagation is predicted. Results show that compared with the non-auxetic ceramic honeycombs which are at an internal cell angle of 30°, the critical temperature of the auxetic ceramic honeycombs whose cell are orientated at an angle of −30° increases by 78.5% and the TSIF at the crack tip decreases by 40%, respectively. Hence, the auxetic structures have better thermal shock resistance. This study indicates that auxetic ceramic honeycombs have significant potential applications in harsh temperature environments.

PGM based catalysts for exhaust-gas after-treatment under typical diesel, gasoline and gas engine conditions with focus on methane and formaldehyde oxidation

The HC and CO oxidation activity of Pt/Al2O3, Pd/Al2O3 and Pd-Pt/Al2O3 catalysts was compared under three exhaust-gas model conditions typical for stoichiometric gasoline as well as lean burn diesel by means of temperature programed conversion tests on laboratory test benches. In order to understand the differences in emission reduction performance, the impact of gas mixture composition was systematically studied with a particular focus on methane and formaldehyde conversion.The catalysts used in this study were prepared by incipient wetness impregnation of Al2O3 followed by washcoating on ceramic honeycombs, and were pre-treated in an equal manner before each activity test.Distinct differences in pollutant conversion were observed over the three catalysts under the investigated conditions. Pd-based monometallic and bimetallic catalysts revealed the lowest temperature for CH4 oxidation (<450 °C) under lean conditions, being lower under lean Diesel than Compressed Natural Gas (CNG) conditions. The reason for this behavior seems to be the higher water concentration in the CNG gas mixture. Furthermore, it was found that the presence of HCs shifts the conversion of methane to higher temperatures, most probably due to produced water during combustion of the HCs. Pt/Al2O3 on the other hand only converts methane at temperatures above 500 °C but no sensitivity to water or the amount of additional HCs was observed. The lowest light-out temperature for formaldehyde oxidation in excess of oxygen was measured on Pt/Al2O3 with full conversion below 125 °C. While this was the case for a model gas mixture of HCHO, H2O and O2, under simulated lean burn gas engine conditions, formaldehyde is oxidized at lower temperature on Pd-Pt/Al2O3 than on Pt/Al2O3 due to the strong inhibiting effect of CO on Pt-particles.Under stoichiometric gasoline conditions, Pt had the highest activity for methane oxidation whereas Pd/Al2O3 and Pd-Pt/Al2O3 hardly convert methane below 500 °C. Unsaturated HCs and CO on the other hand were converted at lower temperature over Pd containing monometallic and bimetallic catalysts in comparison to Pt/Al2O3, showing once again the multiple and complex effects generated by variations in exhaust gas mixture and catalyst composition.

Optimization of the preparation conditions of cordierite honeycomb monoliths washcoated with cryptomelane-type manganese oxide for VOC oxidation

ABSTRACT Ceramic honeycomb monoliths were washcoated with cryptomelane-type manganese oxides and their catalytic performance was evaluated in the oxidation of ethyl acetate. The effect of a mixture of ethyl acetate with toluene and of the presence of water vapour was also assessed. Different coating parameters, namely size of catalyst particles, number of immersions in the washcoating solution, presence of an initial coating with alumina, calcination temperature of this coating, as well as the amount of binding agent and ethanol in the washcoating solution were studied and optimized based on the catalytic activity of the structured catalyst. Small particles are required for a correct impregnation; however, since the smallest particles are less active, an intermediate size achieved the best catalytic results. Increasing the number of immersions over 3 did not significantly increase the catalytic activity of the structured catalyst. The presence of an initial coating with alumina and a binding agent (colloidal alumina) in the washcoating solution was found essential to increase the activity, whereas increasing the calcination temperature after the initial alumina coating above 500°C decreased the activity of the catalyst. The presence of ethanol in the washcoating solution did not significantly improve the activity of the structured catalyst. The optimized structured catalyst presented high catalytic activity in the removal of ethyl acetate (90% conversion into CO2 at 256°C) and high stability during 100 h of reaction. The addition of toluene or water vapour in the feed gas did not significantly affect the activity of the coated monolith.

A method using porous media to deliver gas-phase phthalates rapidly and at a constant concentration: Effects of temperature and media

Phthalates are widely used as additives to consumer products. Many diseases have been shown to be related to the uptake of phthalates. To achieve equilibrium constant phthalate generation for mass transfer and exposure experiments, the present study developed a porous media based method using Teflon generators connected to the media with stainless steel connectors. Carbon sponges with the porosities of 20 ppi (pores per inch), 30 ppi, 40 ppi and honeycomb ceramics of 14 ppi were used as porous media fillers to evaluate the effect of temperature-controlled states, materials, and pore sizes on the generating performance of phthalates. The results showed that 30 ppi carbon sponge fillers at 25.0 ± 0.4 °C performed satisfactorily. DMP, DiBP and DEHP were used as examined phthalates and were generated at 12,800 ± 740 μg/m3, 330 ± 13 μg/m3 and 2.37 ± 0.15 μg/m3, respectively. The times to reach stable concentrations were 4.5 h, 18.5 h and 89.5 h, respectively. The reproducibility of DiBP and DEHP delivery deviated by less than 2.4%. Long-term generating experiments should be performed in the future. The porous media based method could stably deliver gaseous PAEs and tends to be widely used in the research of the adsorption of PAEs on surfaces (airborne particles, settled dust and indoor surfaces) and exposure experiments.

Effect of shunt honeycomb ceramics thickness on finned tube heat transfer in VAM oxidation for hydrogen production

Shunt honeycomb ceramics (SHC) are proposed to constrain operation parameter fluctuation within commercial hydrogen production through gasification method with the steam produced with ventilation air methane oxidation heat. However, the effect of SHC thickness on heat extraction trait was ignored in the former studies. An improved numerical simulation was carried out to study the effect of SHC thickness. Results show that the existence of SHC increases pressure drop is increased by 23.5%, decrease the temperature difference between inlet and outlet, increases average heat flux may be increased by 7.4%. Radiation heat transfer accounts for 0.2374–0.3398 of total heat exchange, and as the SHC thickness grows, radiation heat transfer increases gradually.

Self-sustained combustion of CO with transient changes and reaction mechanism over CuCe0.75Zr0.25Oδ powder for honeycomb ceramic catalyst

A CuCe0.75Zr0.25Oδ catalyst was prepared by the sol-gel method and successfully coated on honeycomb ceramic (HC) carrier. The activity of CuCe0.75Zr0.25Oδ/HC was determined by the CO-TPO + FLIR, with the results performing that the critical condition for CO self-sustained combustion is 3 vol% CO + 3 vol% O2/N2 at 0.5 L/min. As the CO concentration increases from 1 vol% CO to 3 vol% CO, the induction process (<T15) shifts toward a slower CO conversion, while the light-off process (>T15) shifts to rapid ignition with a transient change for the CO oxidation reaction. The furnace temperature for CO self-sustained combustion decreases with increasing the CO and O2 concentrations. Upon increasing the CO2 concentration, however, furnace temperature is needed to increase and realize CO complete conversion. The thermal stability test combined with SEM + EDX results indicate that the CuCe0.75Zr0.25Oδ /HC retains an excellent thermal stability after a 200 h, and the high-temperature region remains at 225 ± 1 °C during the CO self-combustion reaction. The activity of catalyst is reduced slightly after the 200 h test because of the carbon deposition on the catalyst surface, but such a slight deactivation can be eliminated by the air oxidation method. In situ IR results show a competitive adsorption of CO/O2 and CO2 on the Cu-Ce active sites, indicating that the addition of gaseous CO2 performs an inhibition of CO oxidation. CO preferentially adsorbs linearly at Cu+ sites to form carbonyls that react with lattice oxygen to produce CO2 to release, which can be ascribed to M-K mechanism. The L-H mechanism is less important, which involves the relatively weak reaction of adsorbed CO and adsorbed oxygen on the Cu-Ce active sites to form carbonate species.

Controlling the setting times of one-part alkali-activated slag by using honeycomb ceramics as carrier of sodium silicate activator

A solid alkali source is a great choice to make one-part alkali activated materials (AAM). Conventional slag-based AAM always suffer from short setting time and unsafe operation with liquid alkaline activators, thus restricting their usage in industry. This study aims to synthesize a new kind of one-part alkali-activated slag cement by using a porous honeycomb ceramic (HCC) as the carrier of sodium silicate activator. The solid activator was produced by making the honeycomb ceramic absorb water glass (Ms = 3.24, 8.21 wt% Na2O, 25.8%wt SiO2), drying for 5 h at 125 °C and then grinding it to powder with particle sizes between 10 and 50 μm. In this study, the result indicates that setting time of alkali activated slag cement (AASC) was successfully extended to at least 5 h by using the solid activator. The maximum compressive strength of the specimens made with 5% NaOH + 40% HCC and 6% NaOH + 40% HCC was ~40 MPa after 28 d of curing time. XRD (X-ray diffraction), FTIR (Fourier Transform infrared spectroscopy), SEM (Scanning Electron Microscope) and linear shrinkage analysis were applied in order to study the hydration product and the effect of the addition of HCC to the AASC. In terms of the strength properties and setting time, this one-part AASC could be classified as a Type 32.5 N and CEM IIIC class cement according to the European standard EN-197.
