“…(2) The material's yield stress decreases, together with reductions in the rest of the curve, as the total amount of shear energy experienced by the sample increases. This can be due to mechanical mixing [26] and the effect can be quantified in terms of the total shear energy received by the sample prior to the test [27,28].…”

According to former President of Petrobrás, Maria das Graças Silva Foster, in 2013 the Brazil produced about 1 million barrels per day, that is, much of the nation's economic demand is subject to extraction of oil, what determines the country scientific investments for the Betterment of this economic mode, in order to maximize the extraction and prevent environmental damage. On the extraction of oil in the drilling process, a step that is required is the cementing of the well. The cement used in the process is subject to strict conditions of temperature and pressure, and must support fragile and porous rocks, fluids corrosive and pressurized. Therefore, it is necessary to check the rheological behavior of cement paste. This work aims to evaluate the study of rheology and rotational dynamics in cementing oil wells. It is therefore important to improve the homogeneity of the cement and ceramic suspensions because they lose these characteristics when subjected to the transport, mixing and pumping. Was held the addition of minerals and additives in the folder for the oil well cement in accordance with the regulations in force, with the implementation of models of Bingham and dynamic power or oscillatory. Where was evaluated by testing the determination of the potential for speed and tests zeta compression and mechanical traction. Evaluated by testing for developers and rheological tests to determine zeta potential of more than 30 mV being the same stable and mechanical compression and traction test.

“…At the moment, polymeric materials are used as concrete or mortar additives in order to control the rheological properties or to improve the toughness, as protective coatings for civil structures, as adhesives for the reinforcement of bridge structures by bonded composites, and as sealing resins for injecting cracks in concrete [3,4]. Epoxy adhesives are even in most of these applications, a good wettability of the cementitious substrate by the polymer is required in order to promote physico-chemical interactions and ensure an optimal level of adhesion between the mineral and organic phases [5,6]. Therefore, the surface interactions of cementitious substrates, and especially the dispersion and acid-base properties, are of great importance.…”

“…The mixing procedures for the epoxy cement mortar were fairly complicated by the two-component mixing, epoxy resin, and any hardener. The epoxy resins can harden in the presence of alkalis formed from the hydration of cement [1,5,6].…”
