Environmentally friendly viscosity-modifying agent for self-compacting mortar: Cladophora sp. cellulose nanofibres

A Comprehensive Review of Plant-Based Biopolymers as Viscosity-Modifying Admixtures in Cement-Based Materials

“…In addition, cellulose has been used in other forms, including cellulose nanofibers (CFFs) and cellulose filaments (CFs), which constitute a new class of nanocellulose materials. It was agreed that CFs (95% cellulose and 5% hemicellulose) improve the rheological properties particularly the yield stress, the plastic viscosity, and the stability of SCC [32,33]. Hisseine et al claim that the rheological and the stability improvements are due to the hydrophilicity, the high aspect ratio, and the flexibility of CFs [33].…”

Hisseine et al claim that the rheological and the stability improvements are due to the hydrophilicity, the high aspect ratio, and the flexibility of CFs [33]. Furthermore, CFs increase the heat of hydration without causing a delay of the hydration.…”

“…Identically to CFs, they increase the yield stress and the plastic viscosity. Finally, it was mentioned that using 0.03% of CFFs, the performances of concrete were favorable for projected concrete applications [33].…”

Effect of Basalt Fiber Aspect Ratio on Mechanical and Workability Properties of Self-Compacting Concrete

“…Low labor costs and less energy used for compaction are also advantages over conventional concrete [3]. SCC is produced similar to conventional concrete and is produced with a mixture of aggregates, binders, water, mineral, chemical additives and natural additives [4]- [6]. Although concrete is the most used building material with a good performance in terms of compressive strength, its tensile strength and brittleness are problems that need to be solved.…”
