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 ...
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 ...
Limestone calcined-clay cements (LC3) take advantage of the synergetic effects of calcium carbonate reaction with the additional aluminium provided by the calcined clay. As temperature decreases, calcium carbonate solubility increase, therefore, the early- ...
During carbonation, the microstructure of a cement paste is strongly modified, which induces a dynamic feedback loop impacting the global advancement of the reaction. In this study, we investigate the effect of the microstructure model on simulations of ac ...
With the ongoing sustainability movement, the incorporation of limestone powder in cementitious binders for concrete in the U.S. has become a subject of renewed interest. In addition to accelerating the early age hydration reactions of cementitious systems ...
The interest of German building masters towards hydraulic binders grows at the third decade of the 19th century. This acute interest is stimulated by the import of «Roman Cement» from England and by the acquisition of the knowledge related to it. The disse ...
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 ...
Supplementary materials that are utilized to replace ordinary Portland cement (OPC) decrease the workability of the cementitious mixtures and superplasticizers are usually added to cement to control their fluidity. In general, current superplasticizers are ...
This paper evaluates feasibility of alkali activation to boost the reactivity and cementitious properties of recycled glass powder ( GP), when it is used in four different binary mixtures with ordinary Portland cement ( OPC), alkali activated slag or fly a ...
Among different methods of measuring early age autogenous deformation of cementitious materials, the corrugated tube method described in the ASTMC1698-09 standard is one of the most commonly used. Despite the standardization and the common application of t ...
