On a survey conducted in Gulf of Mexico in 1991, it was found that nearly 11000 casing string of 8000 wells posed with SCP problem. ... tangential stress, axial stress, shear stress. Among all these, tangential stress is the principal stress acting on the cement. ... most of the expansion test of oil and gas well cement on laboratory scale is ...
The cement-bone interface was more compliant under tensile than compressive loading at the 0° loading angle only (p=0.024). The coupled transverse to axial compliance ratio, which is a measure of the coupled motion, was small for laboratory prepared (0.115±0.115) and postmortem specimens (0.142±0.101).
For the axial compression tests of the concrete blocks, a thin layer of cement plaster to correct the imperfections of settlement and of the materials was used. This procedure reduces defects that can generate stress concentrations. Reaction walls were used to test the structural masonry, according to the Brazilian Standard NBR 16522 [23].For the …
The basic function of cyclone preheater is gas-solid separation, and the separation effect is determined by the cyclone structure and the distribution of gas 3-dimensional flow field. In this article, a test system is used to measure the 3-dimensional flow field of gas in the preheater cyclone tube. Meanwhile, the resistance loss of the cyclone tube and the …

Even if the cement is not low-alkali cement (below 0.60%), the amount is important for three reasons: Air-entraining agents generally produce more air as the alkali content goes up. Where the alkali occurs in the cement can affect this, but to get a first approximation, we need to track the equivalent alkali content.
The cement and sand were supplied by Lion Head Cement Company in Taiyuan, China. The cement used was P.O. 42.5 Portland cement, with a specific surface area of 4500 cm 2 /g, an initial setting time of 160 min, and a final setting time of 220 min. Its chemical composition is shown in Table 2.The sand underwent screening to ensure …
