Understanding of the factors slowing down metakaolin reaction in limestone calcined clay cement (LC3) at late ages

Karen Scrivener, Paul Bowen, Mohsen Ben Haha, François Henri Avet, Yosra Briki

Factors which could explain the slowing down of the metakaolin reaction in LC3 blends are investigated. Portlandite availability and the presence of aluminium ions in the pore solution are shown not to be limiting factors. ...

Factors affecting the reactivity of slag at early and late ages

Karen Scrivener, Mohsen Ben Haha, Yosra Briki

This study investigates the difference between the reactivity of slag in NaOH solution (w/s = 100) and in cement paste (w/b = 0.4). The reactivity of slag is much higher in NaOH solution than in cement paste. When the NaOH solution is saturated with portla ...

Maximizing the use of supplementary cementitious materials (SCMs) in blended cements

Yosra Briki

Partial replacement of clinker with supplementary cementitious materials (SCMs) is an effective approach to reduce CO2 emissions related to cement production. However, there is a maximum substitution level with SCMs beyond which strength decreases. The und ...

Investigation of the use of Limestone Calcined Clay Cement (LC3) applied to Thailand

Wilasinee Hanpongpun

The replacement of clinker with supplementary cementitious materials (SCMs) is the most interesting solution to reduce the CO2 emissions from cement production. The abundant availability of clays, which have a sufficient amount of kaolinite content in Thai ...

Reaction 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. ...

Development of physical and mechanical properties of a cold-curing structural adhesive in a dry bridge environment

Thomas Keller, Anastasios Vassilopoulos, Maria Savvilotidou

The effect of physical aging and continuation of curing on the physical and mechanical properties of a commercial cold-curing structural epoxy adhesive used in bridge construction has been investigated during the first year. Since adhesive bridge joints ar ...
