Properties of slag based geopolymer reactive powder concrete

Ain Shams Engineering Journal, 2021
Reactive Powder Concrete (RPC) is a high strength concrete with excellent engineering properties. High cement content is one of the important key parameters in the development of RPC. Production of cement considered a non-sustainable eco-friendly process.

Effect of Steam, Carbonation, and Autoclave Curing on the Mechanical, Durability, and Microstructure Properties of UHPC: A Comprehensive Review

Advances in Civil Engineering, Volume 2026, Issue 1, 2026.
Ultra high‐performance concrete (UHPC) is a material that brings revolutionary changes to modern building construction due to its outstanding mechanical, durability, and microstructural properties. This study investigates the impacts of these properties under three distinct curing regimes—steam curing, carbonation curing (CC), and autoclave curing (AC),

Effect of Crushed Concrete on Some Properties of Modified Reactive Powder Concrete Reinforced With Micro Steel Fibers

Journal of Engineering
Conventional RPC does not contain coarse content aggregate, but some researchers incorporate coarse aggregate. Those researchers used coarse aggregate to produce RPC, the new RPC known as modified reactive powder concrete (MRPC).

RPC Effect of Crude Oil Products on the Mechanical Characteristics of Reactive-Powder and Normal-Strength Concrete

Periodica Polytechnica Civil Engineering, 2020
This study includes detailed information on the mechanical characteristics of the hardened concrete mix for normal concrete (NSC) and reactive powder concrete (RPC) after exposure to crude oil products. Two types of crude oil products (kerosene and gas oil) were investigated after exposure for a period of 180 days. The experimental program consisted of

Study of Pressure and Curing Temperature in Reactive Powder Concretes (RPC) with different amounts of Metallic Microfibers [PDF]

Revista de la construcción, 2013
Reactive powder concrete (RPC) is one of the greatest breakthroughs in concrete technology, as it enables the manufacturing of thinner structures without passive reinforcement. That reduces the load in buildings and increases durability, especially in aggressive environments.

An updated review and perspective on efficient hydrogen generation via solar thermal water splitting

WIREs Energy and Environment, Volume 13, Issue 4, July/August 2024.
Solar thermal water splitting (STWS) produces renewable (or green) hydrogen from water using concentrated sunlight. Abstract Solar thermal water splitting (STWS) produces renewable (or green) hydrogen from water using concentrated sunlight. Because STWS utilizes energy from the entire solar spectrum to drive the reduction–oxidation (redox) reactions ...
