Grinding aids are materials that added to cement mixtures improve the characteristics of or increase efficiency milling systems both in clinker grinding (finish grinding) stage. In this study, effects four (Triisopropanolamine based (TIPA), Triethanolamine (TEA), Hydroxylamine (HA), and Calcium nitrate (CN) aids) process were evaluated on essential produced cement: namely specific surface area ...

C-S-H seeding in Portland cements is well known from basic scientific works and field applications. Moreover, this activation approach could be beneficial for low-CO2 under development where a general drawback poor mechanical strengths during the first week of hydration. However, mechanistic understanding different processes taking place when still not developed. Here, we contribute to knowledg...

The equilibrium solubility data of CO2 in the various aqueous blends of triisopropanolamine (TIPA) + monoethanolamine (MEA) with the total alkanolamine concentration of 2 mole / dm3 were measured at the temperatures of 30, 40, 50, 60 and 70 oC and CO2 partial pressures below 100 kPa. The experiments were done in an atmospheric gas absorption syste...

Groundwater is a major drinking water resource but its quality with regard to organic micropollutants (MPs) insufficiently assessed. Therefore, we aimed investigate Swiss groundwater more comprehensively using liquid chromatography high-resolution tandem mass spectrometry (LC-HRMS/MS). First, samples from 60 sites were classified as having high or low urban agricultural influence based on 498 t...
