Chemical Technologies for Modern Concrete Production

2017.1.1 A relatively higher dosage of chemical admixtures but still within a few percent of cement weight is admixed during concrete productions. Commonly used chemical admixture noticed to have relatively significant impacts on clinker and cement reductions are water reducer agents. These allow concrete production with low water to cement ratio (w/c).

Environmental impacts and decarbonization strategies in the cement

2020.9.22 The use of cement and concrete, among the most widely used man-made materials, is under scrutiny. Owing to their large-scale use, production of cement and concrete results in substantial emission ...

2021.12.28 Currently, the production of one ton of ordinary Portland cement (OPC) releases considerable amounts of CO2 into the atmosphere. As the need and demand for this material grows exponentially, it has become a challenge to increase its production at a time when climate-related problems represent a major global concern. The two main

Use of Water Reducers to Improve Grindability and Performance of ...

Assaad and Asseily (2011) researched inter-grinding clinker with water reducers to produce superplasticised cement characterised by improved workability and strength; at a rate of 09% addition ...

Effect of Al2O3/SiO2 ratio on the chroma and phase

2022.8.22 In diluted state (isolated substitution), the oscillator forces are severely reduced, changing the colouring effect in mechanism and intensity. The chroma of clinker can be changed by doping with trace elements or adjusting the chemical composition. Li et al. studied the effect of incorporating ZnO on the whiteness of white Portland cement

Industrial versus Laboratory Clinker Processing Using Grinding

2015.9.14 The evaluation of grinding aid (GA) effect on clinker processing in laboratory grinding mills is relatively simple. Yet, the results obtained cannot be directly transposed to industrial mills, given the fundamentally different operational modes and grinding parameters. This paper seeks to evaluate the scale effect by comparing the

Influence of cement strength class on environmental impact of concrete ...

2020.12.1 The results suggested that using SCMs to produce blended cements reduces the cement strength class, although some exceptions were observed (e.g., CEM I (>90% of clinker) in Portugal had a cement strength class of 42.5 MPa). The reduction in cement strength class affects the concrete performance, which can increase cement
