Cement materials with cellulose added

The use of cellulose, including nano- and microcellulose, in the formulation of cement-based materials, in particular, in composite materials of the construction industry is considered. Cellulose-based materials are a class of biopolymers that can be synthesized by plants, bacteria and algae. When combined with a cement-containing base, they can not only improve the mechanical performance of composite materials, but also have a positive impact on their environmental friendliness throughout the life cycle of the products. The main environmental advantages of cellulose additives include high biodegradability, low toxicity and minimal environmental and health risks. A review of recent work shows that the inclusion of cellulose nanofibers in cement-containing composites can increase the viscosity of matrices, give the material the ability to retain water, and improve a number of its mechanical properties. There is also a trend to increase the compressive and flexural strength of the matrices compared to the samples without such additives.
