Mortar and concrete based on calcium sulphate binders [PDF]

open access: yes, 2006
In this study both hemi-hydrate and anhydrite are tested as calcium sulphate binders for structural mortar and concrete. The advantage of using calcium sulphates instead of cement as a binder is the fact that the production of calcium sulphate is more ...

Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Die ältesten schriftlichen Belege für den Gott Seth [PDF]

open access: yes, 2001
The present paper addresses the alkali activation of Portland cements containing blast furnace slag (20 and 30% of the cement by weight) with a view to the possible use of these materials in oil well construction. The hydration studies conducted showed

Concrete in architecture: Redefining form, space, function, and insights from bibliometric analysis

open access: yesStructural Concrete, EarlyView.
Abstract Concrete has become a cornerstone in architectural and engineering innovation, as it seamlessly integrates structural performance with artistic expression. Its evolution from ancient opus caementicium to contemporary ultra‐high‐performance concrete illustrates its adaptability to the change in technological, environmental, and design paradigms.

Durability and compressive strength of blast furnace slag-based cement grout for special geotechnical applications

open access: yesMateriales de Construccion, 2014
Special foundations, most prominently micropiles and soil anchors, are frequently used in construction today. In Spain, the grout for these special technical applications is generally prepared with portland cement, although the codes and standards in ...

Mechanical and electrical properties of magnetically aligned micro steel fiber‐reinforced self‐compacting concrete

open access: yesStructural Concrete, EarlyView.
Abstract This study investigates the impact of magnetic alignment of micro steel fibers (0.35%, 0.70%, and 1.05% contents) on the mechanical and electrical properties of fiber‐reinforced self‐compacting concrete. A simplified magnetic circuit was designed and built to align the fibers within the concrete matrix.

Optimizing the construction process: State‐of‐art, innovations, and potential benefits of temperature match curing

open access: yesStructural Concrete, EarlyView.
Abstract The temperature match curing (TMC) method significantly enhances the accuracy of concrete property assessments by replicating in situ curing conditions in test specimens. While this method has remained underutilized and relatively unknown in the industry due to its complexity, the advent of Internet of Things and wireless sensor technologies ...
