Chemistry is traditionally divided into organic and inorganic chemistry. The former is the study of compounds containing at least one carbon-hydrogen bonds. 1836-62-0, Name is 2-(2-Methoxyphenoxy)ethylamine, molecular formula is C9H13NO2, belongs to ethers-buliding-blocks compound, is a common compound. In a patnet, author is Li, Chen, once mentioned the new application about 1836-62-0, HPLC of Formula: C9H13NO2.
Effect of polycarboxylate ether on the expansion of ye’elimite hydration in the presence of anhydrite
Polycarboxylate ether (PCE), a commonly used superplasticizer, is known to influence the morphology of ettringite during the early hydration of C(3)A- and ye’elimite-containing cements. According to existing theories, such morphological changes may be crucial to the expansive behavior of these cements. This paper studied the expansion of ye’elimite-anhydrite pastes and found the use of PCE to reduce expansion after 4 days of curing. Hydration studies were conducted by calorimetry, X-ray diffractometry, scanning electron microscopy, mercury intrusion porosimetry, inductively coupled plasma-optical emission spectrometry, and X-ray microtomography. The results show that the influences of PCE on the morphology of ettringite and the hydration of ye’elimite were quite small after 2 days. Based on the crystal growth theory, the range of pores in which ettringite can grow was calculated to explain the observed expansive behaviors. The presence of ettringite nano-crystals in aluminum hydroxide was also revealed and considered as a possible expansion mechanism.
We¡¯ll also look at important developments in the pharmaceutical industry because understanding organic chemistry is important in understanding health, medicine, 1836-62-0. The above is the message from the blog manager. HPLC of Formula: C9H13NO2.
