A Low Albedo, Thin, Resistant Unit in Oxia Planum, Mars: Evidence for an Airfall Deposit and Late-Stage Groundwater Activity at the ExoMars Rover Landing Site.

Oxia Planum, Mars, is the future landing site of the ExoMars Rosalind Franklin rover mission, which will search for preserved biosignatures in a phyllosilicate-bearing unit. Overlying the mission-important phyllosilicate-bearing rocks is a dark, capping unit-known here as the Low albedo, Thin, Resistant (LTR) unit-which may have protected the phyllosilicate-bearing unit over geologic time from solar insolation and radiation. However, little is known about the origin of the LTR unit. Here, we map the LTR unit and investigate its distribution and morphology across 50,000km2 using a variety of orbital remote sensing data sets. The characteristics of the LTR unit include draping palaeo-topographic surfaces, deposition over a wide elevation range, and a consistent vertical thickness that can be best explained by airfall deposition including a primary or reworked volcanic palaeo-ashfall. Previous research suggests that the LTR unit was not significantly buried, and we find it to be preferentially preserved with a high mechanical strength in discrete deposits representing palaeo-topographic lows. We suggest this could be attributed to localized cementation via upwelling groundwater. This scenario suggests that most of the phyllosilicate-bearing exposures may not have been protected over geologic time, as the uncemented LTR sediment would have easily been removed by erosion. However, our observations indicate that the scarped margins of the LTR unit deposits probably exposed regions of the once protected phyllosilicate-bearing unit. These areas could be key science targets for the ExoMars Rosalind Franklin rover mission.

Cement Leakage after Augmentation of Osteoporotic Vertebral Bodies.

Cement leakage is the most common complication of vertebral cement augmentation. The present study investigated cement leakage rates in spinal cement augmentation procedures and identified potential risk factors for cement leakage.140 cases (258 vertebrae) in 131 consecutive patients and nine postmortem cases were evaluated. A total of 258 cement-augmented vertebrae were studied. The data for this were obtained from the hospital records of 131 patients who underwent such operations in 2 orthopaedic trauma surgery clinics in the FRG and from the examinations of 9 postmortem cases at the Institute of Forensic Medicine of the University Medical Centre Hamburg-Eppendorf.Cement leaks were identified in 64 of the 140 cases (45.7%). Local cement leaks were the most common type of leak, accounting for 73.4% of leaks (n=47). Venous leaks were evaluated in 15 cases (23.4%) and pulmonary embolisations in 2 cases (3.1%). Within the group of retrospectively studied cases (n=131), only one patient (0.8%) suffered a symptomatic cement leak. Cement augmentation of fractures to lumbar vertebrae and application of large doses of cement were identified as risk factors for cement leakage.Both the data in the literature relevant to the topic and the results of this work demonstrate a high incidence of cement leakage after vertebral body augmentation procedures. Risk factors for cement leakage are described. Despite the low percentage of symptomatic cases, the possible factors influencing cement leakage should be considered and included in the surgical planning when planning and performing cement augmentations on vertebral bodies.

Simultaneous Removal of Toxic Ammonia (NH3/NH4 +) from Aqueous Solutions Using New Geomaterial Adsorbent: Application to Aquaculture Effluents

This study evaluates the performance of a new geomaterial (GEOM) based on sodium montmorillonite clay (Na-Mt), local activated carbon (CAC) and fine powder local cement (Chlef plant western Algeria) to remove ammonia from fish farming in a recirculating aquaculture system. The aqueous ammonium (NH4 +/NH3) adsorption efficiency of GEOM was compared with its two principals` constituents (Na-Mt and CAC) and another commercial activated carbon (CAG). The results of X-ray diffraction (XRD) and Fourier transform infrared (FTIR) spectroscopy were used to assess the chemical and physicochemical properties of studied adsorbents. The maximum adsorption capacity of NH4 + on GEOM of about 15.57 mg. g-1 seems to be similar to that of Na-Mt 16.82 mg. g-1. The study of solution pH showed that the best NH4 +/NH3 removal efficiency was at pH=6 for both GEOM and Na-Mt. The efficiency of GEOM for ammoniacal nitrogen (NH4 +/NH3) removal was 79.3% in ultrapure water, 94.05% in seawater and 97.5% in real aquaculture wastewater. Thus, the proposed material, GEOM, can be used as a filter material in a bio-filtration process to treat aquaculture wastewater in a real-world context.

Effects of natural zeolite on mechanical properties and durability indexes of concrete

This study evaluated the effects of a locally available natural zeolite (NZ), on properties of concrete. To the best knowledge of the authors, this paper is the first study wherein NZ concrete has been evaluated using durability index methods. The NZ studied is presently not used as pozzolan in the local cement industry, hence its potential use in concrete would be new. In the investigation, concrete mixtures of 0.50 and 0.70 water/cementitious ratios were prepared using CEM I 52.5R cement type blended with 0, 10, 20 and 30% NZ. Performance characteristics of NZ were compared with those of 20% or 30% fly ash (FA), which is a conventional pozzolan. The mechanical properties measured were strength development, workability and setting time. Durability properties including carbonation and a consortium of indexes comprising oxygen permeability index, water sorptivity index and chloride conductivity index were also tested. Interestingly, NZ concretes exhibited good or excellent durability index values and lower carbonation results, relative to those of the corresponding FA concretes. In fact, adding 20% NZ into concrete mixtures gave optimal performance, including significant reduction of carbonation, which is a unique beneficial effect as pozzolans typically increase carbonation.

Biomechanical behaviour of a novel bone cement screw in the minimally invasive treatment of Kummell's disease: a finite element study

ObjectiveTo investigate and evaluate the biomechanical behaviour of a novel bone cement screw in the minimally invasive treatment of Kummell's disease (KD) by finite element (FE) analysis.MethodsA validated finite element model of healthy adult thoracolumbar vertebrae T12-L2 was given the osteoporotic material properties and the part of the middle bone tissue of the L1 vertebral body was removed to make it wedge-shaped. Based on these, FE model of KD was established. The FE model of KD was repaired and treated with three options: pure percutaneous vertebroplasty (Model A), novel unilateral cement screw placement (Model B), novel bilateral cement screw placement (Model C). Range of motion (ROM), maximum Von-Mises stress of T12 inferior endplate and bone cement, relative displacement of bone cement, and stress distribution of bone cement screws of three postoperative models and intact model in flexion and extension, as well as lateral bending and rotation were analyzed and compared.ResultsThe relative displacements of bone cement of Model B and C were similar in all actions studied, and both were smaller than that of Model A. The minimum value of relative displacement of bone cement is 0.0733 mm in the right axial rotation of Model B. The maximum Von-Mises stress in T12 lower endplate and bone cement was in Model C. The maximum Von-Mises stress of bone cement screws in Model C was less than that in Model B, and it was the most substantial in right axial rotation, which is 34%. There was no substantial difference in ROM of the three models.ConclusionThe novel bone cement screw can effectively reduce the relative displacement of bone cement by improving the stability of local cement. Among them, novel unilateral cement screw placement can obtain better fixation effect, and the impact on the biomechanical environment of vertebral body is less than that of novel bilateral cement screw placement, which provides a reference for minimally invasive treatment of KD in clinical practice.

Assessment of the potential of coprocessing as a destination for municipal solid waste in the state of Minas Gerais, Brazil

The current climate crisis has resulted in efforts to reduce greenhouse effect emissions (GEE) both in the industrial and in the public sanitation sectors. In the year of 2022, there were 10 operational cement kilns licensed for coprocessing in the state of Minas Gerais, with a combined production capacity of 18.8 Mt/year. In the same year, 40.2% of the 853 municipalities in the state still disposed of their municipal solid waste (MSW) in irregular dumps and landfills, which corresponds to approximately 2Mt of MSW per year. Given the strong presence of cement industries in the region, the coprocessing of MSW could represent both a useful tool in MSW management and a strategy to reduce the carbon footprint of the sector, as long as the waste characteristics are made adequate to the technical demands of the process. This work assesses different pre-treatment routes in order to prepare MSW for coprocessing in cement kilns. For each scenario, a preliminary analysis of the potential treatment capacity of these wastes by local cement industries is performed. The results indicate that reducing MSW water content, whether through triage or thermal treatment, drastically increases the lower heating value (LHV) and its applicability as an alternative fuel in cement plants. When considering a 25% alternative fuel ratio in cement kilns, up to 590,000 t/year of MSW could be coprocessed in the State of Minas Gerais.

The Effect of Existing Soil on the Unconfined Compressive Strength (UCS) Value on Cement Treated Recycling Base (CTRB) Type Flexible Pavement

Recycling technology or Cement Treated Recycling Base (CTRB) is one method for repairing damage to ancient road pavements, however, when the process is in place (Mixed in place), difficulties can arise, such as mixing with existing soil material that shouldn't be mixed in its implementation. because this will affect the results of Unconfined Compressive Strength (UCS). As a binder in the form of local cement from South Kalimantan, the brand is cheaper because production costs are cheaper. This study aims to obtain UCS Results at minimal cement levels that still meet the requirements with the use of brand local cement, obtain the typical influence of existing soil on UCS and what percentage of existing soil material can still be tolerated either curing or non-curing and correlation and get recommendations for the maximum percentage of influence of percent of existing land on UCS in curing or non-curing conditions. RAM samples were obtained for the purpose of investigation, which was done in a lab, existing soil and additional materials in the field. Inspection of old aggregates, making test specimens with variations in cement content of 1-10%, after obtaining minimum UCS according to technical requirements then making test specimens with variations in soil examinations and soil content of 0%, 5%, 10%, 15%, 20%, and 25% again then conducting data analysis to find correlations / relationships. The results of the research showed variances in cement content of 1% (one) - 10% that still meet the technical specifications of UCS (at least 30 kg/cm²) obtained a minimum cement content of 5% (five percent) with a UCS of 33.77 kg/cm². Then the test results of the influence of existing soil on UCS that is still tolerated are mixed, namely in curing conditions is 17% with the equation Y = -0.10075 x + 46.894 (R2 = 0.964). and non-curing 8.9% with the equation Y = -0.1113 x + 39.814 (R2=0.956). The R2 conclusions for both indicate a very There is a substantial correlation between the two factors

The Milwaukee Formation (Givetian, Wisconsin): gone but not forgotten

Abstract The Milwaukee Formation, a sequence of Givetian (Middle Devonian) marine strata deposited in what is now southeastern Wisconsin, USA, was recognized as preserving an exceptionally diverse biota of invertebrates, placoderms, and plants, when local cement companies mined the rock for the manufacture of hydraulic cement from 1876 to 1911. It is now recognized as containing one of North America's most diverse biotas of its age coming from a single formation, having roughly 250 species, 100 families, 16 phyla, and four kingdoms. Intense collecting has revealed the rich biodiversity that prevailed during the Devonian Period in what is now the Milwaukee area. When the cement mines shut down, the quarries were filled and what was already regarded as a localized series of outcrops became even more restricted. Today the formation is known almost exclusively from limited exposures in Estabrook Park and the adjoining Lincoln Park, in Milwaukee County, in the area once occupied by the cement quarries. These outcrops (the type locality) are protected by a Milwaukee County Park Ordinance that prohibits removing materials from the parks, thus enabling the type locality to remain intact for educational and non-destructive research purposes, while largely unstudied museum collections remain available for ongoing research.

Experimental Research on Natural Pozzolan as Cement Replacement

This paper presents the properties of mortar and concrete with NBRRI pozzolan as partial replacement of cement. In this research, NBRRI pozzolan from NBRRI and local cement (Dangote) are used. Firstly, chemical composition of NBRRI pozzolan and Dangote cement are analyzed. And then the physical properties of local materials used in this research are determined according to ASTM procedure. Partial replacement percentages of pozzolan are considered 10%, 20%, 30% and 40%. The strength of mortar and concrete with NBRRI pozzolan (0%, 10%, 20%, 30%, and 40%) is tested at 7 days, 14 days and 28 days. From the trial mix design, the water-cement ratio (0.555) is obtained by using the least square method. To get target strength (4000 psi), by using water-cement ratio (0.555) and 68% of maximum aggregate size (20 mm), the concrete mix proportion (1:1.9:3) is obtained. The compressive strength of concrete with various percentages of NBRRI pozzolan at 21 days and 28 days are more than 7 days and 14 days strength. Therefore, it can be concluded that NBRRI pozzolan can be used as cement replacement material when high strength performance in structures is not required.

Development of a novel 124 MPa strength green reactive powder concrete employing waste glass and locally available cement

In this study, a new reactive powder concrete (RPC) was developed, with environmentally friendly typical RPC components obtained from ground quartz substituted by the waste glass. In this manner, the carbon footprint and final cost are minimized by replacing aggregates and reducing cement. A challenge in this study was using high-celite phase available cement and avoiding the alkali-silica reaction. The Box–Wilson design and Derringer–Suich optimization were used to create an RPC mixture with a low cement content and high-volume waste glass dosage that achieved a compressive strength of more than 120 MPa. It was demonstrated that having all ground waste glass particles smaller than 1000 µm is not sufficient to prevent the alkali-silica expansion. Furthermore, commercially available cement with a high celite proportion had a modest beneficial influence on the compressive strength at an early-age but a significant detrimental impact on the RPC’s compressive strength at 28 days. Finally, the current study proved the potential of manufacturing an RPC that satisfied the strength threshold criterion while utilizing a local cement with over 12% celite and a substantial volume of waste glass powder comprising more than half of the RPC weight.

Modification of the Aeration-Supplied Configuration in the Biodrying Process for Refuse-Derived Fuel (RDF) Production

Biodrying is an essential part of the mechanical–biological treatment process that minimizes moisture content and simultaneously maximizes heating value for refuse-derived fuel (RDF) production. Although the mechanical separation process operates effectively in Thailand’s RDF production, high organic content levels and their degradation cause moisture contamination in RDF, producing wet RDF. Aeration is essential for an effective biodrying process, and can reduce RDF’s moisture content as well as increase its heating value. To maximize the biodrying effect, aeration should be optimized based on the waste conditions. This study proposes a modified aeration-supplied configuration for wet RDF biodrying. The aeration rate was modified based on the period within the biodrying operation; the first period is from the beginning until day 2.5, and the second period is from day 2.5 to day 5. The optimal aeration supply configuration was 0.5 m3/kg/day in the first period and then 0.3 m3/kg/day until the end of the process; this configuration yielded the greatest moisture content decrease of 35% and increased the low heating value of the biodried product by 11%. The final moisture content and low heating value were 24.07% and 4787 kcal/kg, respectively. Therefore, this optimal aeration-supplied configuration could be applied to meet the moisture content and low heating value requirements of the RDF production standard for Thailand’s local cement industry.

Development of high-volume recycled glass ultra-high-performance concrete with high C3A cement

Ultra-high-performance concrete (UHPC) is a special cementitious composite material with outstanding qualities like compressive strength greater than 120 MPa, and outstanding durability in comparison to other types of concrete. However, its production implies a large carbon footprint and significant consumption of natural resources such as quartz powder and fine quartz sand, both classified as carcinogenic to humans by the International Agency for Research on Cancer. This study produced a UHPC paste created with greener pozzolans and aggregates compared to current UHPC mixture proportions. In this regard, quartz powder and fine quartz sand were replaced by two different sizes of recycled glass powder. Furthermore, reducing the cement dosage was a goal in optimizing the UHPC mixture. This total replacement of the aggregate and reduction of the cement reduces the carbon footprint and the costs of the final material in two different ways: firstly, by decreasing the use of natural resources to produce quartz powder and sand, and secondly, by using waste material that otherwise would occupy landfill space. To reproduce the findings of this paper in developing countries with limited-quality cement, high C3A locally available cement is used in this research. The latter represents a significant challenge in the production of UHPC. Statistical methodologies such as center composite design and multiobjective optimization were undertaken to develop an efficient, healthy, safe, and environmentally friendly mixture design that meets the ASTM strength criteria for UHPC while maintaining the lowest cement content and the highest waste material dosage. The results showed that the fact that all the ground recycled glass particles have a size of less than 1 mm is not a sufficient condition to avoid the harmful alkali-silica reaction. In addition, it was observed that the high C3A content of the locally available cement had a slight positive effect on the 1-day compressive strength but a significant negative effect on the 28-day compressive strength of the UHPC. Finally, the present investigation demonstrated the feasibility of producing a UHPC that, using a local cement with almost 10% C3A, met the threshold criteria with a large volume use of recycled glass powder representing more than fifty percent by weight of total concrete.

Technogenic magnetic particles in topsoil: Characteristic features for different emission sources

Variations in mineralogical composition, grain size internal structure and stoichiometry of technogenic magnetic particles (TMPs) deposited in topsoil may provide crucial information necessary to trace main pollution sources and recognize various technological processes. The aim of the study was to characterize, by means of magnetic parameters and Mössbauer spectra, the TMPs from non-ferrous metallurgy, cement, coke, glass production as well as long range transport (LRT) and compare the obtained data with previous results focused on iron mining and metallurgy. This research shows that only certain pollution sources (e.g. mainly iron mining, iron metallurgy, LRT and partly glass production) can be successfully distinguished by the applied parameters. The main features characteristic for TMPs produced by Fe-mining are: high values of concentration-dependent magnetic parameters, low values of coercivity, significant contribution from coarse MD (multi-domain) grains and a relatively high stoichiometry of magnetite. The most discriminative feature for TMPs generated by the glass industry is the abundance of goethite in the topsoil samples, which is confirmed by magnetic and Mössbauer techniques. The TMPs released by the Ni-Cu smelter and the Pb-Zn waste exhibit significant differences in the Mössbauer parameters, indicating different stoichiometry of magnetite for each group. Such variations are due to replacement of Fe by other elements at tetrahedral sites in the case of TMPs released from the Ni-Cu smelter. TMPs characteristic for the LRT emissions contain higher amount of finer fraction of low-stoichiometry magnetite (mostly single-domain SD particles) than those originating from other sources. The TMPs accumulated in the topsoils around the coking plants cannot be clearly discriminated by the applied methodology due to strong influence of the local pollution sources. Magnetic studies of the TMPs generated by cement production are complicated, since their properties mainly depend on individual technology (e.g. additives) used by the local cement plants.

The Effect of Adding Expanded Polystyrene Beads (EPS) on Polymer-Modified Mortar

This study assessed the efficiency of Expanded Polystyrene (EPS) waste as a 10, 20, 30, 40, 50, and 60% substitute for fine aggregate in the manufacturing of lightweight cement composites. A 4% low-cost latex paint emulsion was added to the cement mortar to reinforce it as an alternative to the more expensive polymer admixtures. This improved the bonding between the cement matrix and the EPS particles because SBR films were produced in the cement matrix. The flexural strength of regular EPS concrete may also be significantly increased by SBR treatment. Eight alternative mix designs were created and evaluated for compressive and flexural strength, thermal conductivity, water absorption, and dry density. The polymer-modified mortar was created using a 0.4 water/cement ratio of local cement, polymer, and polystyrene. The results showed that compared to the standard combination at 28 days of aging, the compressive strength increased up to 29.26Mpa, flexural strength increased to 6.83Mpa, dry density increased up to 1930kg/m³, and absorption decreased by 4.95. Thermal conductivity decreased by 0.8291W/m.k.

Improvement of energy recovery potential of wet-refuse-derived fuel through bio-drying process.

This paper proposes novel wet-refuse-derived fuel (Wet-RDF) bio-drying process with the variation of initial organic substrate and moisture content. The bio-drying was carried out using 0.3 m3 lysimeter aerated continuously at different rates. Two conditions of Wet-RDF feedstock tested included: Experiment A ‒ 37% organic substrate and 58% moisture content with an initial heating value of 2,889kcal/kg; and Experiment B ‒ 28% organic substrate and 35% moisture content with an initial heating value of 4,174kcal/kg. The bio-drying was performed in both experiments under negative ventilation mode and non-ventilation mode, the ventilation mode was set at the aeration rates of 0.2 m3/kg/day and 0.4 m3/kg/day. The results suggest that the optimum aeration rate was 0.4 m3/kg/day, achieving a 30% moisture reduction and a 60% heating value increase from their initial values. As a result, the improved wet-RDF qualified for the local cement industry's standard in terms of heating value.

Some properties of Reactive Powder Concrete Contain Recycled Glass Powder

Every year, millions of tons of waste glass are created across the globe. It is disposed of in landfills, which is unsustainable since it does not disintegrate into the environment. This study aims to produce reactive powder concrete by using recycled glass powder and determine the influence on the mechanical properties. This study investigated the effect of partial replacement of cement with recycled glass powder at two percentages (0, 20) % by weight of cement on some mechanical properties (Fresh density, Splitting tensile strength, Impact Strength, and voids%) of reactive powder concrete containing 1 % micro steel (MSRPC). Furthermore, using steam curing for (5 hours) at 90 degrees celsius after hardening the sample directly, RPC was produced using local cement, silica fume, and a super plasticizer, with a w/c (0.2). It was found the Fresh density increased by about (7.27%), splitting tensile strength increased by about (23.5%) at age 28day, energy that causes 1-st crack increased by about (77.7%), energy that causes ultimate failure increased by about (54.9%) at age 60 days, and a reduction in the voids % by about (12.5)% at age 28 day compared with the reference mixture.

Behavior of reactive powder concrete containing recycled glass powder reinforced by steel fiber

AbstractEnvironmental sustainability is described as one that avoids the depletion or deterioration of natural resources, while also allowing for the preservation of long-term environmental quality. By practicing environmental sustainability, we may assist to guarantee that the requirements of today’s population are satisfied without risking the capacity of future generations to meet their own needs in the future. Engineers in the field of concrete production are becoming increasingly interested in sustainable development, which includes the utilization of the locally available materials in addition to using the agricultural and industrial waste in construction industry as one of the possible solutions to the environmental and economic issues. This study investigated the effect of partial substitution of cement with recycled glass powder (0, 15, 20, and 25%) by weight of cement at various ages (on compressive strength) after determining the optimal ratio of replacement. This optimal ratio is used to study its effect on some mechanical properties (such as flexural strength, absorption, and dry density) of reactive powder concrete containing 1% micro steel fiber (SRPC), and furthermore, utilizing steam curing for 5 h at 90°C after hardening the sample directly. Reactive powder concrete (RPC) has been designed with the use of the local cement, silica fume, and super plasticizer with a water/cement ratio of 0.20 in order to achieve a compressive strength of 137.09 MPa at the age of 28 days. When recycled glass powder replacement (20%) was utilized, the findings revealed that the compressive strength of RPC improved by 4.2%, the flexural strength increased by 15.3%, the dry density increased by 0.61%, and the absorption was reduced by 32% at 28 days after the test results were compared to the reference mix.

Lagrangian particle dispersion (HYSPLIT) model analysis of the sea breeze case with extreme mean daily PM10 concentration in Split, Croatia.

The case of a sea breeze where the mean daily PM10 concentration reached the recommended limit value for human health for the period from 2007 to 2009 at the air quality station AMS3 Split-1 in Split, Croatia, is analysed. The Pennsylvania State University/National Center for Atmospheric Research (PSU/NCAR) atmospheric model MM5 and the Hybrid Single-Particle Lagrangian Integrated Trajectory (HYSPLIT) model are used to simulate the lower atmospheric flow and dispersion within 100km from the coast. The simulation is made with four point sources in the hinterland of Split: Kaštel-Sućurac, Solin and Klis, where the local cement plants are located, and Vranjic, where an asbestos-cement plant is located. Statistical analysis and rotational statistics showed good agreement of the measurement data with the modelled wind speed and direction at 10m and temperature at 2m height. The backward trajectories show that the pollutants are caught in the sea breeze circulation from all sources and in the early afternoon the plume is placed over parts of Split from all sources. From the peak concentrations during the selected day, it can be concluded that pollution from Kaštel-Sućurac had the greatest impact on the high PM10 concentrations measured at the Split-1 station.

Effect of Sustainable Glass Powder on the Properties of Reactive Powder Concrete with Polypropylene Fibers

Global warming and environmental damage have become major problems. The production of Portland cement releases large quantities of gas, which cause pollution to the atmosphere. This problem can be solved via the use of sustainable materials, such as glass powder. This study investigates the effect of partial replacement of cement with sustainable glass powder at various percentages (0, 15, 20, and 25%) by weight of cement on some mechanical properties (compressive strength, flexural strength, absorption, and dry density) of Reactive Powder Concrete (RPC) containing a percentage of Polypropylene fibers (PRPC) of 1% by weight. Furthermore, steam curing was performed for 5 hours at 90oC after hardening the sample directly. The RPC was designed using local cement, silica fume, and super plasticizer with a water/cement ratio of 0.2 to achieve a compressive strength of 96.3MPa at the age of 28 days, and it was tested at percentages of sustainable glass powder replacement of 0 and 20% by weight of cement. According to the study's findings, RPC's compressive strength rose up to 4.2% as a consequence of the use of sustainable glass powder replacement by 20%, flexural strength up to 15.3%, dry density up to 0.49%, and absorption reduction by 31.7% at the age of 28 days and in comparison with the reference mixture.
