The production process of MHEC powder involves several sequential stages. It commences with the extraction of cellulose from natural sources like wood pulp or cotton. Subsequently, the extracted cellulose undergoes alkalization. The ensuing step encompasses etherification via sodium mono chloroacetate, culminating in the production of MHEC. This resultant substance is then subjected to purification, drying, and milling, ultimately yielding the final MHEC product.
This study was conducted using a CEM I 52.5N sample (“Milke®” from HeidelbergCement AG, Heidelberg, Germany). Its properties are presented in Table 1. Composition of the cement was obtained by Q-XRD using a Bruker axs D8 Advance instrument (Bruker, Karlsruhe, Germany) with Bragg–Brentano geometry. Topas 4.0 software was employed to quantify the amounts of individual phases present in the sample by following Rietveld's method of refinement. The amounts of gypsum (CaSO4·2H2O) and hemi-hydrate
