Alkali-activated materials (AAMs) have been extensively studied for their superior performance and eco-friendliness. While previous researches primarily focused on the hardened properties of AAMs, assessment fresh has often overlooked. The preparation process AAMs involves key factors in mix design that significantly impact workability. This study comprehensively evaluates workability different types analyzing a total 402 mixtures extracted from 26 individual papers. examination focuses AAM...
Abstract Carbonated cement pastes (CCP) can be used as stable carbon storage. In this work, CCP were systematically investigated supplementary cementitious materials (SCMs)‐like components in ordinary Portland (OPC) paste. The fully hydrated pulverized into powders and then exposed to different CO 2 pressure conditions (i.e., 1.0, 2.0 2.5 MPa) for 24 h. These mixed with OPC form a new binder. Various fresh, hardened microstructural properties of the mixtures investigated. Initial results...
In the majority of world, tap water is not available for construction and containing various salts only choice. However, effect such has been scrutinized systematically. this work, mechanism drying shrinkage ordinary Portland cement paste prepared with was investigated The wastewater three types salts, i.e., sodium hydroxide (NaOH), sulfate (Na2SO4), calcium (CaSO4), cured at two different relative humidity (RH) conditions. Various fresh hardened properties mixtures were examined. Tests...
Design and synthesis of high-performance single-molecule magnets (SMMs) have long been a research focus. Inspired by the best dysprosium(III) metallocene SMMs bis(methanediide) SMMs, we assumed dysprosium which had electrical neutrality combining two types ligands. As Dy
Abstract This project studied the drying shrinkage of alkali-activated cement paste exposed to 75%RH environment, considering effects types (i.e. NaOH, Na2SO4, and CaSO4) dosages 1M, 2M, 5M) alkali activators. In this work, length weight changes ‘mini-bar’ samples were measured evaluate degree for each group. Through comparing results pastes mixed with different salts, it has been found that was usually exaggerated due addition salts. However, when 5M OPC showed fewer strains (even volume...
Asphalt concrete (AC) exhibits significant inherent anisotropic behavior due to the preferential orientation of internal aggregates. In previous work, anisotropy compacted AC sample was quantified by using inclination angles aggregate particles. However, limited attention has been devoted study how predict degree through geometric parameter before specimen compaction. Moreover, relationships between and parameters particles have not established. this paper, four types specimens were prepared...
