摘要: Abstract Objective : This paper investigates the potential and limitations of using relatively low volume fractions cellulose nanofibre as reinforcement in cement pastes. Materials methods General use limestone (GUL) gel suspension were used preparation paste. Mixture conductivity, hydration, flexural strength, energy absorption fibre dispersion hardened matrix evaluated. Results Cellulose reduced conductivity early age hydration mixtures. However, at 28 days, cumulative heat degree pastes containing higher than those unreinforced reference mixture. Optimum mechanical properties observed for paste 0.1% nanofibre. The decrease content is a result agglomeration. In comparison to paste, strength increased by approximately 106% 184%, respectively.
