The modern use of concrete developed in the eighteenth and nineteenth centuries from the interest in archaeology, the observation of some vernacular building techniques and some construction-site practices that had survived locally from the times of ancien ...
At the turn of the 19th century, the production and use of concrete were limited by the unavailability of raw materials to produce good cement in several places. From that time onwards, the progress of chemistry and a number of empirical discoveries opened ...
This paper presents a comparative study on the corrosion rate and microstructural characteristics of Portland cement (PC) and calcium aluminate cement (CAC)-based concrete mixtures subjected to microbially-induced sulphuric acid (biogenic H2SO4) attack for ...
Through a collaborative work established between CIDEM and the Laboratory of Construction Materials at EPFL, a new cementitious system based on a synergetic combination of calcined clay and limestone as Portland's clinker replacement was developed. The nov ...
The development of Ultra-High Performance Concrete (UHPC) opened new research directions for enhancing the architectural design, sustainability and serviceability of concrete structures. However, the costs and resource intensiveness trigger the need for in ...
Autogenous shrinkage is the unrestrained volume change of cementitious materials occurring at con-stant temperature without any change in mass. It occurs as a consequence of self-desiccation (de-crease of internal relative humidity) and increasing capillar ...
Progress in understanding hydration mechanisms of alite and Portland cement is reviewed. Up to the end of the induction period, dissolution rates determined by the undersaturation of the solution dominate the reaction, but, better understanding is needed a ...
BookTubers are a rapidly growing community in YouTube who shares content related to books. Previous literature has addressed problems related to automatically analyzing opinions and mood of video logs (vlogs) as a generic category in YouTube. Unfortunately ...
Through a collaborative research effort between the Ecole Polytechnique Federal de Lausanne and CIDEM a new kind of cementitious binder has been developed based on the synergy between calcined clays and limestone. Industrial trials carried out in Cuba duri ...
The aim of this thesis is to understand the mechanisms underlying the main hydration peak and later ages of alite hydration; it proposes new mechanistic models for these two stages.Alite is the main constituent of Portland Cement (PC), and is responsible ...
