Dye adsorption by magnetic modified biochar has now received growing interest due to its excellent performance and facile separation for recycling. In this study, nano iron oxide-modified was fabricated via the successive hydrothermal-pyrolyzing method using Chlorella vulgaris (Cv) FeSO4·7H2O as raw materials, on Rhodamine B (RhB) in aqueous solution studied. Multiple techniques such X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM),...
The effect of atmospheric pressure on performance air entraining agent (AEA) and concrete was studied in Tibet Hubei, China. result shows that the reduced increased surface tension lowered foaming property solution. AEA with excellent ability stability is preferred low pressure. freeze‐thaw deterioration process hardened pastes relatively faster under frost resistance more sensitive than mechanical property. bigger pores poor uniformity internal pore size distribution led to macroscopic...
We proposed a type of low-alkali liquid state setting accelerator , named HLSA; it was environmentally friendly product. To investigate the temperature adaptation and cement flexibilities HLSA, time strength development properties with HLSA were discussed in this paper. The effects on hydration process, products, microstructure studied by means X-ray diffraction (XRD), thermogravimetric analysis (TGA), scanning electron microscope (SEM), mercury intrusion porosimetry (MIP). results show that...
The goal of this paper provides better understanding the effect sodium gluconate (SG) on ordinary Portland cement (OPC) hydration behavior. Pastes’ performances cement, including setting time at 20°C and 35°C curing temperature, mechanical strength, fluidity, zeta potential are studied. Furthermore, effects SG behaviors investigated by means isothermal calorimetry measurements, X‐ray diffraction (XRD), thermogravimetric analysis (TGA). results show that is difficult to maintain significant...
Purpose The purpose of this paper is to introduce an interval finite element method (IFEM) simulate the temperature field mass concrete under multiple influence uncertainties e.g. environmental temperature, material properties, pouring construction and pipe cooling. Design/methodology/approach Uncertainties significant factors such as ambient adiabatic rise, placing cooling are comprehensively studied represented numbers. Then, IFEM equation derived a for obtaining results based on...
Comparison of the influence amino trimethylene phosphonic acid (ATMP) and sodium gluconate (SG) on performance concrete are investigated in this paper.The comparison effects ATMP SG setting time at 20°C or 35°C, slump loss, compressive strength cement pastes dry shrinkage investigated.The results show that retard effect is much stronger than dosage higher obvious, "temperature adaptability" worse ATMP; both have "auxiliary water reducing effect" "slump loss resistant effect", nevertheless...
The present study envisaged the development of a novel admixture based on composites amino trimethylene phosphonic acid and boric (AB) that exhibited an intense inhibition hydration effects for Portland cement. was aimed to lay solid foundation utilization AB in large volume concrete by reducing temperature control measures. setting time at different temperatures, compressive strength cement pastes containing were examined. characteristics investigated using isothermal calorimetry...
Enhancing the durability and extending service life of concrete are crucial for promoting its sustainable development. Applying surface coatings is primary technical method used to improve durability. In this study, based on plasma thermal spraying technology, a thermal-sprayed, ceramic-based coating was prepared evaluated using drawing method, X-ray diffraction scanning electron microscopy with energy dispersive spectroscopy, computed tomography (X-CT), frictional wear. Subsequently,...
Abstract To improve the accuracy and efficiency of fish behavior assessment, this paper focuses on quantitatively exploring variations relationships between different monitoring dimensions. A systematic comparison was conducted 3D 2D behavioral factors using an infrared tracing system, during both day night. Significant differences in swimming distance were observed among methods, as determined by two‐way ANOVA Tukey's test. correction applied to account for disparities distance, ensuring...
Abstract Improving the durability and extending service life of concrete is one most important means to improve sustainable development concrete. Surface coating main technical method In this study, based on plasma thermal spraying technology, a thermal-sprayed ceramic-based was prepared surface evaluated using drawing method, X-ray diffraction scanning electron microscopy with energy dispersive spectroscopy, computed tomography, frictional wear. Subsequently, performance tests were...
Abstract The microstructure differentia of fly ash doped cementitious materials between before and after dissolution was observed by XRD MIP to analyze the microstructural deterioration characteristics different samples. Results showed that there were great changes in hydration products, cement clinker particles dissolution. Pore structure evolution during indicated effect C-S-H decalcification on pore not negligible traditional definition harmful harmless applicable.
Abstract The performance development of the composite cementitious material system with fly ash and milled dam were investigated. results show that, compared ash, special morphology has not significant effect microaggregate at initial hydration stage. Under same conditions, a larger water demand ratio longer setting time, early strength concrete is relatively low, but later increases rapidly, which basically equivalent to ash. After mixing phosphorous slag powder, cementing obviously...
