摘 要：Wood nanofibers from industrial waste have been used as polymeric material to reinforce the cement paste to a content of up to 2%by weight of *** effect of the wood nanofibre content on the porosity,the compressive strength and the degree of hydration of the cement was *** results showed an improvement in compressive strength of over 50%with 1%of added *** modification of nanofiber wood by grafting alkyl chains to their surface can reduce the amount of water absorbed by the *** of an anionic additive(SDBS)to the mixing water improves the surface of the samples more and more by minimizing the pore size by emulsion effect,hence the water absorption *** degree of hydration of the cement increased with the cellulose content containing *** analysis revealed that the presence of nanofibers favored the hydration of the cement by producing more calcium silicate gel and portlandite,probably the main reason for this improvement in compressive strength.
