One of the most common types of cellulose ether is methylcellulose (MC), which finds extensive use in construction as a thickener and a stabilizer in cement slurries. Another prominent example is hydroxypropyl methylcellulose (HPMC), utilized extensively in pharmaceuticals as a binder in tablet formation and in food products as a texture modifier. These applications showcase the ability of cellulose ethers to enhance the properties of other materials without compromising their integrity or safety.

In previous publications, the impact of molecular weight of cellulose ethers on both water retention and rheological properties of mortars has been investigated. The authors conclude that consistency was increased and water retention was improved by higher molecular weight ethers. The mortar rheology is highlighted as one of the key properties relative to water retention [12]. Other studies discussed the influence of cellulose ethers on water transport in the porous structure of cement-based materials and investigated their effect on cement hydration [13], [14]. They found that the type of substituents attached to the anhydro glucose ring of the cellulose ether is critical for water transport and development of the microstructure of fresh and hardened cement. Furthermore, the degree of substitution represents the key parameter relative to cement hydration, as was evidenced by different time periods at which portlandite precipitation occurs.
