A facile approach to a corncob biorefinery, focusing on both carbohydrate valorization and lignin stabilization, was proposed to coproduce platform chemicals (glucose, xylose, arabinose, and furfural) and lignin. Different metal chloride prehydrolyses of c ...
Since the introduction of cementitious materials over 200 years ago, its use has multiplied many fold to be currently at 3 billion tonnes per year, accounting for about 8% of worldwide carbon emission which is forecast to double within the next 30 years. U ...
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 ...
Cement hydrates and their chemically bound water content are sensitive to changes in relative humidity (RH) and temperature. This may cause specific solid volume changes affecting dimensional properties of hydrated cement paste such as shrinkage, swelling ...
Supplementary cementitious materials (SCMs) are currently used to replace part of the clinker to reduce the environmental impact of cement and to favor the use of local materials. Two representative SCM have been used in this work: slag and fly ash. Each o ...
Crystallization is a process of great practical relevance in which rare but crucial fluctuations lead to the formation of a solid phase starting from the liquid. As in all first order first transitions, there is an interplay between enthalpy and entropy. B ...
This paper is the work of working group 3 of the RILEM Technical Committee on Hydration and Microstructure of Concrete with SCM (TC 238-SCM). The pore solution is an essential but often overlooked part of hydrated cements. The composition of the cement por ...
Calcium silicate hydrate (C-S-H) is the main hydrate phase in Portland cements. Its composition
varies depending on the Ca/Si ratio and on the presence of other ions such as aluminium (called CA-
S-H) or alkalis.
This thesis aimed to study the compositi ...
The content of individual amorphous supplementary cementitious materials (SCMs) in anhydrous and hydrated blended cements was quantified by the PONKCS [1] X-ray diffraction (XRD) method. The analytical precision and accuracy of the method were assessed thr ...
Rietveld quantitative phase analysis has become a widespread tool for the characterization of Portland cement, both for research and production control purposes. One of the major remaining points of debate is whether Portland cements contain amorphous cont ...
