In this work, the effects of partial replacements of Portland cement by rice-husk ash (RHA) on
the autogenous shrinkage were investigated. Pastes with water/binder ratio 0.30 and …

Cementitious materials are known to be sensitive to cracking at early ages. During the first
days which follow the contact between water and cement, the system is continuously …

Building construction and building operations have a massive direct and indirect effect on
the environment. Cement-based materials will remain essential to supply the growth of our …

Early age deformations, when restrained, lead to an increase of cracking risk of the material,
especially in the case of high strength materials to which we apply modern high energy …

A crescente utilização de betões de alto desempenho (com grande libertação de calor
durante a reacção de hidratação do cimento) tem vindo a acentuar a importância da análise …

L'objectif du présent travail est de développer un outil facile à utiliser qui est capable de
prédire l'évolution au jeune âge et le comportement de matériaux cimentaires. Le code de …

Autogenous shrinkage is of concern in high performance concrete mixtures, when specific
properties like strength and durability are enhanced. Factors like low watercement ratio, low …

L'objectif de ce travail de thèse était de concevoir un outil capable de simuler le
comportement chemo-mécanique des bétons bas-pH employés dans les structures de …

Slag cement concrete is usually preferred for the design of mass concrete structures
exposed to the marine environment, due to chloride binding capacity and low heat of …
