In order to develop a low-cost electromagnetic interference shielding and especially absorbing cement materials. the present study, utilization of natural magnetite in matrix for this purpose was investigated. The dielectric, magnetic wave properties magnetite/cement composites were characterized frequency range 2.6–3.95 GHz (S band). results show that dielectric losses increased, performance is greatly improved by adding powders as absorbers. For magnetite/composites, two matching thickness...
This study is focused on the effect of basalt fiber road performance asphalt mixture. The mixture with different dosages was comprehensively evaluated using Marshall Stability test, wheel tracking three-point bending beam test and freezing-thaw splitting test. lignin reinforced polyester also were tested to compare results showed that can enhance mechanical properties, low-and high-temperature water sensitivity significantly. Considering economic benefits, appropriate dosage about 0.3%....
The performance of an asphalt mixture will deteriorate under the condition salt erosion, but there are different opinions on mechanism deterioration. Few studies have focused relation between change void characteristics and deterioration exposed to erosion. To explore air voids mechanical damage in was measured by splitting strength. specimens, immersion solutions, mortar, aggregate were scanned with CT technology. segment voids, Otsu method used over mortar solution range values. A...
This study aimed to analyse the attenuation law of skid resistance steel slag asphalt mixture (SSAM) based on differential wear. In this study, an indoor accelerated wear instrument was used accelerate SSAM surface. A pavement laser scanner and a dynamic friction tester measured three-dimensional morphology coefficient (μ) SSAM. Then, improvement mechanism expounded by analysing surface microtexture, mineral composition, chemical composition aggregates. The results showed no linear...
Lignin fibers typically influence the mixture performance of stone matrix asphalt (SMA), such as strength, stability, durability, noise level, rutting resistance, fatigue life, and water sensitivity. However, limited studies were conducted to analyze on percent voids in mineral aggregate bituminous (VMA) during design. This study analyzed effect different fiber contents VMA SMA A surface-dry condition method test Marshall Stability applied with four (i.e., flocculent lignin fiber, polyester...
This study intends to predict the long-term skid resistance of steel slag asphalt mixture (SSAM) from mineral composition aggregates. The polished stone value (PSV) and aggregates were assessed using accelerated polishing test X-ray diffraction, respectively. hardness (H) surface texture richness (STR) calculated aggregates, then a multivariate linear model was established between PSV H STR. British pendulum number (BPN) three-dimensional morphology SSAM evaluated pavement laser scanner,...
This study was intended to evaluate how citric acid influences the time-dependent rheological properties of magnesium oxychloride cement (MOC). For this purpose, parameters, setting time, electrodeless resistivity, crystal phases, morphology, hydration product, and compressive strength were investigated. The results show that addition can improve MOC pastes due retarding effect acid. dosages 0.15, 0.25, 0.35% stabilize paste in 1, 2, 3 h, respectively. prolonged stage by introducing free H+...
In order to evaluate the macro-mechanical performance of asphalt mixture suffered from sulphate–water–temperature–load coupling action, self-designed dynamic water–salt attack apparatus was adopted for accelerated simulation real service conditions in sulphate enrichment environment. Splitting test at room temperature and low conducted assessing still water immersion multi-factor action. Then damage characteristics under different were explored. The multi-linear regression analysis t-test...
The long-term friction performance of safety-focused surfacing, especially high-friction surface treatment (HFST), relies primarily on the properties aggregate. Nevertheless, inconsistencies exist in and attributes requirements for aggregates across country. A study was conducted to evaluate calcined bauxite steel slag selected HFST. Differences were identified between British Standard (BS) AASHTO test methods aggregate abrasion polishing. Laboratory tests determine mechanical, physical,...
