The IR spectra showed that only precipitate C presented the characteristic band of sulfate groups (807 cm−1) and was, therefore, the sulfoacetylated derivative. CSA presented a degree of acetylation of 2.70 and a degree of sulfonation of 0.063, and the presence of sulfate groups in the derivative displaced the position of C(6) to a lower field in the 13C-NMR spectrum and influenced reduced viscosity as a function of concentration. The evaluation of CSA as an additive showed that for a polymer/cement ratio of 0.6%, an increase of 13.80% was achieved consistently, and an increase of 21.05% in the potential tensile of adhesion strength was also achieved.Submitted by Edileide Reis (leyde-landy@hotmail.com) on 2014-08-13T12:58:47Z No. of bitstreams: 1 Daniel Alves Cerqueira.pdf: 1548064 bytes, checksum: c384169a014654e8fd6dd98eae38ac1f (MD5)Approved for entry into archive by Patricia Barroso (pbarroso@ufba.br) on 2014-08-13T17:44:43Z (GMT) No. of bitstreams: 1 Daniel Alves Cerqueira.pdf: 1548064 bytes, checksum: c384169a014654e8fd6dd98eae38ac1f (MD5)Made available in DSpace on 2014-08-13T17:44:43Z (GMT).
