In recent times, the increasing concerns about environmental pollution and public health have made the use of conventional coagulation coupled with sand filtration not effective in meeting the stringent water regulations [6, 7].In order to overcome the limitations of conventional water treatment, the development and application of enhanced composite coagulants which …
Steel slag (SS) is a solid waste produced in the process of steel smelting. Approximately 150–200 kg SS is produced per 1 ton crude steel [1].China is the largest SS producer in the world, accounting for more than half of the world's SS production, but the utilization ratio of SS is only 29.5% in China [2].The low activity and high content of unstable …

The composite TCM tends to have an increased water uptake with increasing MgSO 4 content. However, the extent of the hydration of MgSO 4 in the composite shows a decreasing trend with the hydration rate of MgSO 4 increasing with the addition of diatomite. This suggests that the diatomite improve the mass transfer of the composite TCM.

When serving in marine or groundwater environments, the service life of reinforced concrete structures is far less than expected. Due to the presence of chloride and sulfate, reinforced concrete will rapidly corrode and deteriorate [1], [2], [3], [4].In the environment of chloride and sulfate, due to the presence of a large number of chloride ions and sulfate ions, …
The properties of constituent materials and variation of the mix ingredients mostly affect the quality of concrete produced. This chapter describes constituent materials of concrete and provides information about composition and types of Portland cement (as described in the United States, Canada, and the United Kingdom) including supplementary cementitious …

1. Introduction. Calcium sulfate whiskers (CSWs) are single crystals with a large aspect ratio that have excellent properties such as good shape integrity, high strength, high temperature resistance, chemical resistance, and high toughness [1,2,3].When used as reinforcing fillers, CSWs significantly improve the impact resistance, modulus, and heat …
This can be attributed to the PE@BSO composite separator's good affinity for the electrolyte, both in terms of coating and internal matrix, as well as the ultra-thin barium sulfate coating, which allows the PE@BSO composite separator to absorb a large amount of the electrolyte to fill its internal pores, thus reducing scattering during light ...

This study aims to investigate the effect of calcium sulfate whisker (CSW) on the properties and microstructure of cement-based composites. Further, nanosilica (NS) was used as a comparison.
When sodium sulfide is used, appropriate amount of ammonium sulfate and 1:1 sodium sulfide are added. It can improve the recovery of copper oxide ore. The reason is that the decrease of PH value after adding ammonium sulfate is beneficial to the increase of HS – concentration, the acceleration of sulfidation reaction and the flotation of ...
