Investigation of C-A-S-H composition, morphology and density in Limestone Calcined Clay Cement (LC3)
Karen Scrivener, Emmanuelle Boehm Courjault, François Henri Avet
In this study, the C-A-S-H composition, morphology and density are characterized for Limestone Calcined Clay Cement (LC3-50) blends containing clays with various kaolinite contents. Significant incorporation of aluminium is observed for LC3-50 blends compa ...
PERGAMON-ELSEVIER SCIENCE LTD2019Concrete Performance of Limestone Calcined Clay Cement (LC3) Compared with Conventional Cements
Karen Scrivener, Lionel Sofia, François Henri Avet
This study aims to demonstrate the robustness of concrete made of limestone calcined clay cement (LC3). Two campaigns were carried out using 375 kg.m(-3) and 500 kg.m(-3) of binder and targeting plastic and self-placing workability, respectively. The concr ...
AMER SOC TESTING MATERIALS2019Rapid, Robust, and Relevant (R3) Reactivity Test for Supplementary Cementitious Materials
Karen Scrivener, Ruben Anton Snellings, François Henri Avet, Xuerun Li
Although supplementary cementitious materials (SCMs) are now commonly accepted and widely used, consensus has not been reached for methods to test their chemical reactivity. A multitude of test methods exist but often fall short on one or more of the key f ...
AMER CONCRETE INST2019Performance of Limestone Calcined Clay Cement (LC3) with various kaolinite contents with respect to chloride transport
Karen Scrivener, François Henri Avet, Hamed Maraghechi
The durability of mortar and paste mixtures with respect to chloride ion ingress was investigated for binary blends of Portland Cement Calcined Clay, and ternary systems of Limestone Calcined Clay Cement (LC3). Five clays from various sources with differen ...
SPRINGER2018Chloride Transport Behavior of LC3 Binders
Karen Scrivener, François Henri Avet, Hamed Maraghechi
Corrosion of metal reinforcement is the most important durability concern of concrete infrastructures. In this research, chloride transport in mortars prepared using ternary blends of OPC-calcined clay-limestone (LC3) as the cementitious materials is asses ...
SPRINGER2018Hydration Study of Limestone Calcined Clay Cement (LC3) Using Various Grades of Calcined Kaolinitic Clays
Karen Scrivener, François Henri Avet
In this study, the influence of the calcined kaolinite content of calcined clay on the hydration of Limestone Calcined Clay Cement (LC3-50) is investigated. It is shown that with the increase of the calcined kaolinite content of the calcined clay, the clin ...
SPRINGER2018Reaction Degree of Metakaolin in Limestone Calcined Clay Cement (LC3)
Karen Scrivener, François Henri Avet
The amount of reacted metakaolin is determined using two methods: mass balance and thermodynamic modeling. It is found that mass balance is the most promising method. Thermodynamic modeling gives slightly underestimated results at late ages. ...
SPRINGER2018Investigation of the grade of calcined clays used as clinker substitute in Limestone Calcined Clay Cement (LC3)
The combination of calcined kaolinitic clays and limestone in Limestone Calcined Clay Cement (LC3) is a promising approach to reduce the cost and the CO2 emissions of cement production by reducing the clinker content of cement. This thesis investigates the ...
EPFL2017Development of a new rapid, relevant and reliable (R-3) test method to evaluate the pozzolanic reactivity of calcined kaolinitic clays
Karen Scrivener, Ruben Anton Snellings, Mohsen Ben Haha, François Henri Avet, Adrian Alujas Diaz
The present paper introduces a new rapid, relevant and reliable (R-3) test to predict the pozzolanic activity of calcined clays with kaolinite contents ranging from 0 to 95%. The test is based on the correlation between the chemical reactivity of calcined ...
