High autogenous shrinkage property is one of the disadvantages ultra‐high‐performance concrete (UHPC), which may induce early age cracking and threaten safety structure. In present study, different dosages calcium sulfoaluminate (CSA) cement were added in UHPC as an effective expansive binder. Hydration mechanism, property, compressive strength carried out to investigate effect CSA addition on mechanical properties UHPC. Scanning electron microscopy was also employed characterize intrinsic...
The compressive strength of complex binders containing two or three blended mineral admixtures in terms glass powder (GP), limestone (LP), and steel slag (SP) was determined by a battery solution type testing machine. morphology microstructure characteristics binder hydration products were also studied microscopic analysis methods, such as XRD, TG-DTA, SEM. mechanical properties the cement-based materials analyzed to reveal most appropriate admixture content. early sample development with GP...
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...
Portland slag cement (PSC) and supersulfated containing phosphogypsum (SSC) both contain large volume of ground granulated blast-furnace (GGBS), which can present few carbons’ emission promising broad application. This paper investigated the evolution characteristic performance microstructure these two pastes under sulfate attack compound chemical attack, including visual appearance, compressive strength, pore structure, hydration products morphology. The results show that SSC group...
Cement production is associated with a significant CO2 footprint. Substituting waste resources for cement not only reduces consumption but also contributes to the sustainable development of environment. The incorporation glass slag and steel into cementitious materials addresses resource conservation enhances properties resulting materials. In this work, synergistic effect powder (WGP) (SSP) on mechanical microstructure cement-based has been studied.The results show that when WGP added...
Abstract In this study, the sequential Mann-Kendall and Yamamoto test analysis are used to determine abrupt changes in temperature Huang-huai-hai River Basin, while time series via traditional linear regression for different period is identify basic trend of temperature. The results suggest that data can be divided into three periods: 1961-1985, 1986-1995 1996-2011. slope annual during 1996-2011 were -0.07°C(10yr) −1 , 0.40°C(10yr) 0.04°C(10yr) respectively. These stages defined as follows:...
