Characterization and properties of cementitious composites with cellulose fiber, silica fume and latex

In this investigation, the behavior of the composites was analyzed through mechanical and physical tests, scanning electron microscopy and X-ray diffraction at 28 days cure time. Central composite design with four center points and using alpha for orthogonality of 1.41421, resulting in 18 experiments, was used. The diffractograms show a possible decrease of portlandite in mixtures with the presence of silica fume and natural rubber latex....
