Feasibility of Using Sugar Cane Bagasse Ash in Partial Replacement of Portland Cement Clinker

open access: yesBuildings, 2023
This work presents a technical and economic study using sugar cane bagasse ash (SCBA) to partially replace Portland cement clinker. To evaluate the technical viability, the replacement rates of 10, 20, and 30% of Portland cement were used in the ...

Study of alkaline hydrothermal activation of belite cements by thermal analysis [PDF]

open access: yes, 2010
The effect of alkaline hydrothermal activation of class-C fly ash belite cement was studied using thermal analysis (TG/DTG) by determining the increase in the combined water during a period of hydration of 180 days.

Portland cement clinker from reduced basic oxygen furnace slag [PDF]

open access: yes, 2021
Basic oxygen furnace slag (BOFS) is a by-product of the steelmaking process, of which about 10.4 Mt are produced annually in the European Union. Besides its predominant use in road construction, earthwork, and hydraulic engineering, it is also possible ...

Proposed textural indexes to quantify the distribution of the portland cement clinker phases

open access: yesMateriales de Construccion, 1988
Some textural parameters to quantify the distribution of the Portland cement clínker phases are proposed. These parameters are evaluated under reflected-light microscopy and allow the characterization of Clinker homogeneity.

Properties of concrete incorporating locally produced Portland limestone cement

open access: yesAin Shams Engineering Journal, 2018
Blended cements are increasingly being used in concrete to reduce the amount of clinker in the cement, thus achieving both economic and environmental gains. The use of limestone as a component of Portland cement is now common practice worldwide. Reducing

In-situ curing mechanism of Portland cement [PDF]

open access: yesEPJ Web of Conferences, 2019
The paper presents the results of predictive modelling of the curing mechanism of the type CEM I 42.5B Portland cement using the VCCTL tool. The curing lasts during 28 days at 20 оС and the water-cement (W/C) ratio of 0.26, 0.30, 0.35 and 0.40.
