UTILIZATION OF SLAG POWDER AND RECYCLED CONCRETE WASTES IN REACTIVE POWDER CONCRETE

open access: yesMateriali in tehnologije, 2023
Using recycled wastes and industrial by-products in construction materials has become mandatory to conserve the natural resources and manage waste-disposal environmental problems. This experimental work investigates the workability and strength properties of reactive powder concrete (RPC), utilizing slag powder and finely ground recycled concrete waste

Experimental and numerical studies on the fire resistance of prestressed reactive powder concrete beams

open access: yes, 2022
The prestressed reactive powder concrete beam (PRPCB) is an advanced structural member that can take full advantage of the ultra-high compressive strength of reactive powder concrete (RPC) and the high tensile strength of tendons.

Durability of Reactive Powder Concrete

open access: yesIOP Conference Series: Materials Science and Engineering, 2019
Abstract Concrete is a generally used material in building construction. The construction will be built on the ground and could also be in places exposed to sea water. Sulfate contained in ground water and sea water could cause sulfate aggression to concrete itself.

Experimental Study of Durability of Reactive Powder Concretes

open access: yesJournal of Materials in Civil Engineering, 1996
The durability of reactive powder concretes (RPC) has been defined by measuring porosity, air permeability, water absorption, diffusion, and migration of chloride ions, accelerated carbonation, resistance to reinforcement corrosion, resistivity, and resistance to mechanical abrasion.
