A new approach for production of reactive powder concrete: lightweight reactive powder concrete (LRPC)

Materials and Structures, 2016
Currently, reactive powder concrete (RPC) has been used in the production of structural beam components, manhole covers and similar road accessories etc. In this study, the production of lightweight reactive powder concrete (LRPC) was aimed by using pumice aggregate so as to gain advantage on transportation due to its lowered weight.

Usability of ignimbrite powder in reactive powder concrete road pavement

Road Materials and Pavement Design, 2016
In this study, reactive powder concrete (RPC) was used as the concrete for rigid pavement. In the production of RPC, one of the materials that increases the cost is cement. In the study, in order to decrease the amount of cement in the RPC mixture, the usability of ignimbrite powder as binder along with cement was investigated. Ahlat stone powder (ASP)

Reactive Powder Concrete as a Polymer Modified Concrete

Restoration of Buildings and Monuments, 2012
One of the varieties of cement-based composites, characterized by ultra high strength, are the materials belonging to a group called Reactive Powder Concretes (RPC). These materials, of compressive strength of several hundred MPa, are achieved through appropriate selection of components and the use of different technological treatments.

Ultrasonic testing of reactive powder concrete

IEEE Transactions on Ultrasonics, Ferroelectrics and Frequency Control, 2004
Concrete is a critical material for the construction of infrastructure facilities throughout the world. Traditional concretes consist of cement paste and aggregates ranging in size from 6 to 25 mm that form a heterogeneous material with substantial compressive strength and a very low tensile strength.

Principles of Reactive Powder Concrete

2021
There have been multiple developments and improvements in concrete technologies that had impacts on structural system in recent years. The cement mixtures are used with silica fumes in place of steel fibers and silica fumes (pozzolanic materials) in the form of superplasticizers and are classified as ultra-high-strength concretes to enhance the slab ...

Experimental Study of Durability of Reactive Powder Concretes

Journal 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.
