Influence of aggregates grading and water/cement ratio in workability and hardened properties of mortars
(ELSEVIER SCI LTD, 2011)
Mortar is the material responsible for the distribution of stresses in masonry structures. The knowledge about the fresh and hardened properties of mortar is fundamental to ensure a good performance of masonry walls. ...
The influence of the mixing time in the rheological behavior of cement pastes
(2008-12-01)
Rheology has the purpose to study the flux and deformation of materials when submitted to some tension or outer mechanical solicitation. In practice, the effective scientific field broached by rheology is restricted only ...

Rheology and mechanical aspects of a self-compacting soil-cement in the fresh state
(Univ Fed Rio De Janeiro, Lab Hidrogenio, 2017-01-01)
The article presents a study of design parameters for the fresh self-compacting soil-cement so that it can be framed under the action of its own weight in the production of prefabricated elements. In the experimental work, ...
Optimizing the Water-Oil Emulsification Process for Developing CPC Microspheres
(Univ Fed Sao Carlos, Dept Engenharia Materials, 2016)
Spherical calcium phosphate cement carriers were synthesized by water/oil emulsion. A 23 factorial design was employed in order to optimize the size and form of the microspheres. Stirring speed, liquid-to-powder ratio and ...
