Evaluation of Pozzolanic Reactivity of Artificial Pozzolans [PDF]

open access: yesMaterials Science Forum, 2012
Pozzolanicity is a very interesting issue regarding building materials, as a way to enhance mortars and concrete durability. This property results from the reaction between calcium hydroxide and silica and alumina based materials. Different types of natural and artificial pozzolans show pozzolanic activities that differ depending on the materials ...

Studying the compressive strength, permeability and reinforcement corrosion of concrete samples containing silica fume, fly ash and zeolite [PDF]

open access: yesJournal of Structural and Construction Engineering, 2021
Reinforced concrete is the most commonly used construction material. The durability of reinforced concrete mostly depends on the surrounding environmental and exposure conditions such as carbonation, corrosion, and freezing and thawing.
