Why Does Concrete Turn Black What Causes Discoloration

Why Does Concrete Turn Black What Causes Discoloration

Jan 29, slag is a byproduct of refining iron and steel. it has many of the same properties found in cement, which makes it an effective replacement. slag concrete tends to have a lighter color than usual, which makes discoloration even more noticeable. all the same issues effect slag concrete just as they do standard.

Utilization Of Waste From Steel And Iron Industry As

Utilization Of Waste From Steel And Iron Industry As

Jul 05, the viability of combining waste slag produced from steel (basic oxygen furnace) and iron (blast furnace) industry as replacement of cement in cement mortars was investigated. the impacts on the normal consistency, setting times, soundness, compressive strength, microstructure, and durability of cement paste/mortar were.

Sustainable Approach For Linz

Sustainable Approach For Linz

Jul 13, linz-donawitz (ld) slag, solid waste produced during steel manufacture in basic oxygen furnace, is difficult when it comes to handling and disposal and has very limited utilization. to increase its reusability, the suitability of supplanting cement with ld slag in concrete was examined. to study the impact of partially replacing cement with ld slag on strength, microstructure, and durability.

Utilisation Of Steel Slag As An Aggregate In Concrete

Utilisation Of Steel Slag As An Aggregate In Concrete

Mar 18, for some time, these slags have been used as a cement supplement but, since slag is a very hard material and the cost of its grinding is increased, thus causing the higher cost of cement production, grinding of slags has turned out to be unprofitable. for that reason the use of steel slag as an aggregate in concrete is currently being.

Utilisation Of Steel Slag As An Aggregate In Concrete

Utilisation Of Steel Slag As An Aggregate In Concrete

Mar 18, this paper aims to investigate the possibility of utilizing steel slags produced in croatian plants as a concrete aggregate. aggregate properties were determined on coarse slag fractions (4–8, 8–16 mm) according to the relevant european standards. considering the obtained results, slags were specified in accordance with the classes as given in the main european standard for aggregates.
