Incorporation and solidification mechanism of manganese doped cement clinker

open access: yesFrontiers in Chemistry, 2023
Using municipal and industrial solid waste as a substitute raw material and fuel in cement rotary kiln co-processing is considered an economic and environmentally friendly alternative to the use of traditional fuels. However, the presence of heavy metals

Risk-based Optimization of Sensor Distribution in Roof Constructions – A Conceptual Study [PDF]

open access: yesE3S Web of Conferences, 2020
The objective of placing moisture sensors in roof constructions is to warn about leakage events, and thus avoid undesirable consequences. However, considering that placing an additional sensor is directly related to increasing the total cost of the ...
