Ultramarine blue pigment degradation in cementitious materials: a new approach to the phenomenon <p>The paper analyses the degradation process of commercial ultramarine blue pigments in cementitious materials. For this purpose, two commercial pigments (with and without a protective coating) in different solutions and cement pastes are studied incrementally. The results show that pigment degradation occurs due to an ion exchange phenomenon; during hydration high ion contents are released, calcium and potassium being the most aggressive for the pigment. Calcium distorts the unit cell; between the sodium of the pigment and the potassium in the medium a cation exchange phenomenon takes place. Both processes lead to the diffusion of sulphate and sulphide ions from the pigment to the medium causing loss of colour and the formation of ettringite.</p> G. Rodríguez de Sensale S.

A total of ten numbers of mixes were produced, including HVFYA-SCC made without recycled concrete aggregates and coal bottom ash (as control) along with HVFYA-SCC mixes made with recycled concrete aggregates (from 25% to 50%) and coal bottom ash (from 10% to 30%). The compressive and shear strength of the HVFYA-SCC mixes were improved by 7% and 4%, respectively, with the incorporation of 20% coal bottom ash and 25% recycled concrete aggregates after 120 days of curing. On the other hand, scanning electron microscopic analysis revealed that incorporating coal bottom ash exhibited the pozzolanic reactions with fly ash densified the binder-aggregate matrix of the resulting HVFYA-SCC.</p> A.

The tensile strength and appearance morphology of BFRP bars were analyzed. Used scanning electron microscopy (SEM) to examine the microscopic morphology and used the bond-slip constitutive model to fit the bond-slip curves. When BFRP bars after exposed to 300 °C, their tensile strength dropped by 42%. With the increasing temperature, the bond strength and stiffness of normal concrete (NC) specimens decreased by 27.3 % and 67.5 %, respectively, while HFRC specimens decreased by 20.8 % and 55 %, respectively. Hybrid fibers increased the bond strength and stiffness of HFRC specimens by 27.1 % and 49.1 %, respectively. The best fitting models were the Malvar model and the Continuous Curve model.</p> Zhenrong Liu Huaxin Liu Weixing Xu Beibei Liu Yue Zhong Jian Geng Genjin Liu Copyright (c) 2024 Consejo Superior de Investigaciones Científicas (CSIC) 2024-03-25 2024-03-25 74 353 e334 e334 10.3989/mc.2024.361123 Life cycle analysis and economic evaluation of cement and concrete mixes with rice husk ash: application to the Colombian context <p>Rice husk residues are generated within the rice industry. In this research, the environmental impact of the use of rice husk ash is evaluated as a replacement for cement in the production of concrete in the city of Ibagué (Colombia). The environmental criteria of cement and concrete production alternatives were evaluated through life cycle analysis methodology, using SimaPro 9.3.3 software and the Recipe 2016 Midpoint (H) evaluation method. The economic cost of each of these production alternatives was included. To carry out the study, surveys and interviews had to be undertaken with rice-producing plants, aggregates, cement and concrete plants in Tolima. It was corroborated that rice husk ash (RHA) generated during the rice husk (RH) gasification process for electricity and heat production was beneficial from an environmental and economic perspective when it was used in cement and concrete in the city of Ibague (Colombia).</p> Sindy Sofía Suárez Silgado Lucrecia Calderón Valdiviezo Carolina Betancourt Quiroga Copyright (c) 2024 Consejo Superior de Investigaciones Científicas (CSIC) 2024-03-18 2024-03-18 74 353 e335 e335 10.3989/mc.2024.350723 Influence of crystallizing type chemical admixture on precast micro concretes: a statistical analysis and holistic engineering overview <p>The aim of this paper is to evaluate the influence of a crystallizing chemical admixture on precast micro concretes with two water contents (7% and 11%, by dried mass) and two different conditions of exposure. Thus, precast micro concretes with a composition of 1:3 (cement: fines) with and without crystalline chemical admixture were evaluated on compressive strength (at the age of 28 and 154 days) and water absorption by immersion (at the age of 154 days). Statistical analysis showed that the only significant factor was the effect of the water content on the compressive strength. Besides that, the most significant factors for the water absorption and voids index properties were the water content, followed by the exposure conditions, and the interaction between the water content and the presence of the chemical admixture. The crystalline admixture was insignificant in the conditions of this research.</p> R. C. Lopes G. W. Bacarji E. Bacarji A.M.

This study investigates the impact of RCA on concrete’s workability, compressive strength, flexural, split tensile, drying shrinkage, electrical resistivity, rapid chloride penetration, and microstructural characteristics using XRD, SEM, and EDAX. Test findings showed that increasing the replacement percentage beyond the optimum value (RCA 25) had detrimental effects on the strength and microstructure of the concrete. RCA 25 has a higher compressive, flexural, and split tensile strength in the order of 11.56%, 3.06%, and 5.17% respectively compared to reference concrete, as well as 5.23% increase in drying shrinkage, 8.79% higher electrical resistivity, and 4.68% higher resistance to chloride penetration than reference concrete.</p> H.

Recycled Asphalt Pavement (RAP) aggregate used as recycled aggregate has a lower water absorption than natural aggregate due to its bituminous structure, which reduces the water requirement of fresh concrete. In this study, it was aimed to determine the optimum use of RAP particles as aggregate in concrete for read pavements and to determine their durability properties. For this purpose, RAP was used instead of crushed stone aggregate used in concrete road construction. RAP was used by replaced aggregate 0%, 25%, 50% and 100% of the crushed stone aggregate used on the concrete road. The dose of the produced concrete was 350 kg/m<sup>3</sup> and the water/cement ratio was kept constant as 0.45. The fresh workability and air content of concretes containing RAP were determined. Compressive strength, splitting tensile strength, electrical resistivity value, accelerated corrosion test of hardened concretes were subjected to corrosion resistance, water absorption and porosity percentage, acid resistance, ultrasonic pulse rate and Scanning Electron Microscope (SEM) and X-ray Diffractometer (XRD) analyzes were determined. In the experimental results, it has been observed that the use of RAP ratio of 25% and 50% remains within the limit values for concrete pavement. It is recommended to be used on reinforced concrete roads that will be exposed to adverse environmental conditions with its high corrosion resistance, thanks to its anti-corrosion feature.</p> Tayfun Uygunoğlu İlker Bekir Topçu Emriye Çinar Resuloğullari Copyright (c) 2024 Consejo Superior de Investigaciones Científicas (CSIC) 2024-03-25 2024-03-25 74 353 e338 e338 10.3989/mc.2024.356823 Experimentation and numerical analysis of the influence of geogrids with emulsion insertion on the behavior of bituminous pavements - Case of Ouargla aerodrome <p>This paper presents an experimental study on a set of 30 specimens, tested on three-point bending, divided into two categories. With the insertion of geogrids and cathodic emulsions, the first category consists of 14 prismatic beams and the second of 16 pre-cracked and reinforced slab specimens. In situ tests were carried out using a heavy deflectometer (HWD) on a flexible runway of an airfield located in the city of Ouragla (800 km south-east of Algiers), before and after its reinforcement. This work showed, with a numerical calibration, that the geogrid with emulsion, improves the displacements and the stresses approximately 30% and increases the modulus of elasticity and the modulus of rupture (MOR) by 60% and 20%, respectively. The damping coefficient (k) can reach the value of 2 to 5, which increases the longevity of a reinforced flexible pavement.</p> R. Bazine M. Abdessemed S. Kenai N.
