Corrosion Behavior of Steel Embedded in Ternary Concrete Mixtures

International Journal of Electrochemical Science, 2011
The main reason for the premature failure of reinforced concrete structures is corrosion of the reinforcements. The use of new mortars based on ternary mixtures, an alternative to ordinary Portland cement (OPC), requires extensive research in order to ...

A Study of the Hydration of Lime-Pozzolan Binders

Journal of Thermal Analysis and Calorimetry, 1998
DTA/TG and TG/DTG thermal studies and XRD investigations were carried out on pastes of lime-pozzolan binders to examine the relative hydration process. The binders were prepared with two natural pozzolans and hydrated lime, mixed together in different proportions. The main hydrated phases formed in the pastes are calcium silicate hydrate (CSH) and mono-

Evaluation of Foamed Concrete Properties Containing Engineered Pozzolans and Compressive Strength Prediction Through Artificial Neural Networks

International Journal of Concrete Structures and Materials
The performance of foamed concrete (FC) is significantly influenced by the type and proportion of supplementary cementitious materials (SCMs). However, comprehensive studies investigating the combined effects of engineered pozzolans on the thermal ...

Particle size distributions and shape identification of pozzolanic materials via various dimensional representations

Hybrid Advances
Although pozzolanic materials exhibit unusual particle properties, their particle size distributions and shape identification remain poorly understood. Approximating these geometrical features using simplified plugins is critical for optimising the use ...
