Abstract Recycled aggregates (RA) are frequently obtained from various
unknown sources, which caused variation in properties among recycled aggre-
gates concrete (RAC). This paper investigated the macro and microscopic proper-
ties of RAC prepared with RAs originated from different parent concretes with
90-day strength ranging from 30 MPa to 100 MPa. These parent concretes were
prepared in advance and crushed to produce RA of distinct qualities. The attached
mortar content can reach up to 69% in the concrete with highest strength grade.
The microscopic investigation on different RAC was conducted with the X-ray
Micro-Computed Tomography scanning technique and image process. Experi-… More >

Abstract In this paper, roots and copper slag were used to overcome the weak-
ness and reinforce the mechanical property of soft soil. The experiments were
designed by the Response Surface Method (RSM), the content optimizing of
the root permeated copper slag mixed soil for achieving appropriate values of
shear strength and the final results evaluating were also conducted by RSM. Four
independent variables including moisture content (12–21% by dry weight of the
mixture), slag content (10–20% by dry weight of the mixture), roots content
(0–1.1% by dry weight of the mixture), and aspect ratio of roots L/d (5–40) were
studied… More >

Abstract In this investigation, a new silicone rubber-based MRE material was
prepared to be used as a forming medium in manufacturing thin-walled complex-
shaped Ni-based tubes through the bulging process. Thus, it is significant to
investigate the effect of magnetic field intensity, magnetic field loading time, and
angle on the mechanical properties of the prepared MRE material during the curing
process. The obtained results showed that increasing the magnetic field intensity
during the curing process can improve the orientation of the chain structure in the
elastomer matrix effectively. However, its mechanical properties are the best under
the corresponding magnetic field intensity… More >

Abstract According to the preparation method commonly used for soy proteinbased
adhesives, alfalfa leaf protein was used as the raw material to prepare alfalfa
leaf protein-based wood adhesive. Differential scanning calorimetry analyzer
(DSC), X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR)
were used to characterize properties of the alfalfa leaf protein-based adhesive
in this paper. The results revealed the following: (1) Chemical compositions and
chemical structures of the alfalfa leaf protein were basically identical with those
of the soy protein, both belonging to spherical proteins with the basis and potential
for protein adhesives preparation, and spatial cross-linked network structures would… More >

Abstract The Chinese fir wood was impregnated using a cyclic increasingpressure method (CIPM) with phenolic prepolymers as the impregnating modifier.
Unmodified Chinese fir and progressive increasing-pressure method (PIPM)
impregnated Chinese fir were used as reference samples and were compared and
analyzed. The product’s chemical structure, internal morphology, crystal structure,
and heat resistance were characterized. The transversal and longitudinal sections
showed better filling effects, so that it bore greater external loading and reduced
the water storage space. CIPM infused more phenolic prepolymer into the Chinese
fir. Not only producing more physical filling but also forming more hydrogen bond
associations and chemical bond… More >

Abstract Biocoagulants emerges as a promising technology in water treatment,
in order to exploit renewable and biodegradable materials. The present work aims
to study the coagulant action of chitosan and carboxymethylchitosan on water
with very high turbidity (above 300 NTU), contrasting the physicochemical
results with those obtained for aluminum sulphate. Carboxymethylchitosan was
produced by the Williamson’s ethers synthesis and characterized by potentiometric titration, FTIR and 1
H-NMR. The coagulant tests were performed using
synthetic water in a Jar-test equipment, through the induction of high and low
velocity gradients, followed by sedimentation. The results showed turbidity and
color removal efficiencies above 99%… More >

Abstract The paper discusses the mechanical and thermal performance manifested in natural nanorods attapulgite (ATP) reinforced Acrylonitrile butadiene
styrene (ABS) nanocomposites in the process of fused deposition modeling
(FDM). Molten extrusion technique was taken to manufacture the filaments of
ABS/organic-attapulgite (OAT) nanocomposites with different mass fraction
and the printing operation was made by one commercial FDM three-dimensional
(3D) printer. Results indicate that the mechanical performance of these FDM 3D
printed specimens are improved obviously via the introduction of OAT, and tensile strength of the ABS/OAT nanocomposites parts with only 2 wt% OAT addition is enhanced by 48.1%. At the same time,… More >

Abstract Drought is one of the major abiotic stresses that affect plant growth and
reduce agricultural productivity. Use of algal extract as a biostimulant is gaining
increased attention from researchers. This study aimed to investigate the potential
of Ulva prolifera extract (UE) as a biostimulant when enzymatically extracted
under conditions of water deficit. UE treatments (0.02%, 0.06%, and 0.1%) significantly improved the shoot length, root length, and dry weight of roots after
120 h of drought stress relative to that in treatment with the negative control.
An increase in catalase (CAT) and peroxidase (POD) activity was also observed
that resulted in… More >

Abstract Bayer red mud (BRM) is a kind of industrial solid waste characterized
by huge volume and high alkalinity. Its disposal generates serious environmental
pollution and occupies a large number of farmland. The utilization and recycling
of BRM is currently a crucial issue and needs to be addressed as soon as possible.
The chemical composition of BRM is similar to cement clinker. In this study, the
feasibility of preparing Belite-ferroaluminate clinker (BFAC) with different BRM
was explored. The physical properties, mechanics performance, radioactivity
levels and trace harmful metals leaching were measured. XRD, BEI and EDS
were used to characterize the mineral… More >
