Chemical and mechanical characterization of ternary cement pastes containing metakaolin and nanosilica
This paper, for the first time, focuses on the characterization of the chemical and mechanical properties of ternary cement pastes with the addition of up to 18% of metakaolin and colloidal nanosilica. The paste containing 15% of metakaolin and 3% of nanosilica presented an increase of 44% on the compressive strength and a reduction of 66% on the average pore diameter at the age of 91 days, in comparison with the reference paste. Results obtained remark the high potential of ternary cement mixes produced with
the combination of metakaolin and nanosilica for the production of high performance cementitious materials.The authors would like to thank the postgraduate program in Structural Engineering and Construction from University of Brasília, Furnas Centrais Elétricas, Addendum to the Framework Agreement for Collaboration between University of Brasilia (UnB-Brazil) and Spanish National Research Council (CSIC-Spain) (ref: 201504001653451013W-2017), Eduardo Torroja Institute for Construction Science, Geology Institute from University of Brasília, Geochronology Laboratory from University of Brasília, Chemistry Institute from Federal University of Goiás, State University of Goiás and Unievangélica Center of Anápolis.Peer reviewe
Investigation of C-S-H in ternary cement pastes containing nanosilica and highly-reactive supplementary cementitious materials (SCMs): Microstructure and strength
This pioneering study reports on the investigation of C-S-H in as-produced ternary cement pastes while
highly reactive supplementary cementitious materials, such as silica fume (SF) and metakaolin (MK), and
colloidal nanosilica (NS) are included into the mixtures. Several techniques are used to evaluate the
microstructure of the pastes containing colloidal NS (3%), SF (10%) and MK (10%): Consistency, compressive
strength, thermogravimetric analyses, Fourier transform infrared spectroscopy, scanning electron
microscopy (with energy dispersive X-ray spectrometry), 29Si-nuclear magnetic resonance, and mercury
intrusion porosimetry. Ternary mixtures containing SF or MK require the highest superplasticizer (SP)
consumption of 1.55% and 1.92%, respectively. Impressively, in late stage of aging, i.e 28 and 91 days
of hydration, ternary mixtures reach compressive strength respectively above 90 MPa and 100 MPa,
meaning an increase of about 30% above of the compressive strength of the reference paste. Moreover,
the ternary MK-based paste shows increase C-S-H production, decreasing Ca/Si ratio and superior
increasing mean chain length (MCL) of about 11.1 while compared with the MCL of the reference paste
(about 4.6). Likewise, the highest relative reduction in mean porous size (56%) and the lowest totalThe authors would like to thank the Furnas Centrais Elétricas, Chemistry Institute from Federal University of Goiás, State University of Goiás and Unievangélica Center of Anápolis, Postgraduate Program in Structural Engineering and Construction from University of Brasília, Brazil Geology Institute from University of Brasília, Geochronology Laboratory from University of Brasília, Addendum to the Framework Agreement for Collaboration between University of Brasilia (UnB-Brazil) and Spanish National Research Council, Spain (CSIC-Spain) (ref: 201504001653451013W-2017), Eduardo Torroja Institute for Construction Science.Peer reviewe
Properties of ternary cement pastes with nanosilica and rice husk ssh
The present study reports on the pioneering addition of rice husk ash (RHA) and silica fume (SF) into portland cement-based (PC-based) materials, combined with nanosilica (NS), aiming to assess the impact of the RHA on the mechanical and microstructure properties of ternary mixtures. Pastes were prepared to perform compressive strength tests, thermal analysis (DTA/TG), infrared spectroscopy, and mercury porosimetry. The highest reduction in the calcium hydroxide index (CH.I) and the highest calciumsilicate- hydrate (C-S-H) formation are found in the PC-based ternary mixture containing NS plus SF and NS plus RHA after 91 days of hydration. In line with the aforementioned trends, the ternary mixtures containing NS show the highest compressive strength values and reduction of mean diameter of porous. Indeed, we found strong evidence of synergistic effect in ternary mixtures incorporating NS plus RHA or SF, thus supporting their use in fabrication of cementitious materials.Peer reviewe
Effect of partial substitution of highly reactive mineral additions by nanosilica in cement pastes
The phenomena involved in portland cement hydration and interactions with nanosilica are very complex and not yet fully understood. In addition, few papers have currently proposed to investigate the microstructure and mechanical properties of ternary mixtures using portland cement, colloidal nanosilica, and highly reactive mineral additions. This article investigates, for the first time, the behavior of different highly reactive mineral additions (silica fume and metakaolin) when partially replaced by colloidal nanosilica in the microstructure and hydration of cementitious materials. For the study of the cementitious material microstructures, a Langavant calorimeter, compressive strength, X-ray diffraction, thermogravimetry, infrared spectroscopy, and mercury intrusion porosimetry were used. The pastes with a 1% substitution of highly reactive mineral additions by nanosilica showed higher compressive strength and more refined porosity than the pastes with only silica fume or metakaolin. The results show that nanosilica appears to have better synergism with metakaolin than with silica fume.The authors also acknowledge the support provided by the European Commission, by Marie Curie IRSES Project GREAT (FP7-PEOPLE-2013-IRSES-612665), Addendum to the Framework Agreement for Collaboration between University of Brasilia (UnB433 Brazil) and Spanish National Research Council (CSIC-Spain) (ref: 201504001653451013W-2017), and by the Laboratory of Ceramic Materials (LACER) of the Federal University of Rio Grande do Sul (UFRGS-Brasil) for the laser granulometry and specific surface BET tests.Peer reviewe
Analysis of the Microstructure and Porosity of Cement Pastes with Functionalized Nanosilica with Different Contents of Aminosilane
This research aims to analyze the effect of functionalized nanosilica (NSF) with different levels of amine groups in the formation of hydration products. Four cement pastes were investigated, one reference with Portland cement and three replacing 1% of Portland cement by nanosilica (NS), NSF with a low content of amine groups, and NSF with a high content of amine groups. The heat of hydration of the pastes was evaluated up to 7 days of hydration, the amount of calcium hydroxide (CH) and hydrated phases by means of the thermogravimetric analysis (TGA) test and compressive strength at 2, 7, and 28 days, and porosity through tests of mercury intrusion porosimetry and computed tomography at 28 days of hydration. It was possible to observe that the NSF directly influenced the hydration kinetics of the pastes, delaying the hydration of the Portland cement; however, it demonstrated a similar mechanical performance to the paste with NS at 2 days of hydration and an increase of 10% at 28 days of hydration due to the improvement in the hydration process. Thus, it is possible to conclude that the functionalization of NSF with a low 3-aminopropyltriethoxysilane (APTES) content is promising for use in cementitious materials and may improve hydration and mechanical performance at more advanced ages compared to NS
Energy Balance, CO2 Balance, and Meteorological Aspects of Desertification Hotspots in Northeast Brazil
The main objective of this study was to evaluate meteorological variables and the simulated components of energy and CO2 balances in desertification hotspots in Northeast Brazil. Meteorological data were obtained from the National Institute of Meteorology measurement network for the Cabrobó and Ibimirim sites. Initially, hourly linear trends were calculated for the meteorological variables using the non-parametric Mann–Kendall test. Then, the seasonal variability in the components of energy and CO2 balances was assessed through simulations of the simple tropical ecosystem (SITE) model. Results showed evidence of increasing air temperature trends in the Cabrobó site in the first months of the year, which was not observed in the Ibimirim site. Regarding relative humidity, increasing trends were observed in a few months over the Cabrobó site, while decreasing trends were observed in the Ibimirim site. Opposite behaviors were also identified for the trends in wind speed in both sites. Gross primary production (GPP) and net ecosystem exchange (NEE) simulated values were higher in the first half of the year in both sites. GPP varied from 0.8 to 1.2 g C m−² h−¹, and NEE fluctuated around approximately −5 g C m−² h−¹. These results indicate that rainfall seasonality is a crucial factor for the modulation of CO2 and energy balance fluxes in the Caatinga biome
