In general, the hydroxyl group makes alcohols polar. 527-07-1, formula is C6H11NaO7, Because of hydrogen bonding, alcohols tend to have higher boiling points than comparable hydrocarbons and ethers. Category: alcohols-buliding-blocks
Li, Ran;Lei, Lei;Sui, Tongbo;Plank, Johann research published 《 Approaches to achieve fluidity retention in low-carbon calcined clay blended cements》, the research content is summarized as follows. High meta kaolin content (e.g. 50 wt%) present in a calcined clay blended into a composite cement is pos. with respect to early strength development, but significantly decreases the dispersing effectiveness of PCE superplasticizers. Moreover, it has been observed that for such cements, slump retention is much more difficult to achieve than in OPC or other composite cements. In this study, several approaches to achieve extended workability times in mortars prepared from composite cements holding 20-40 wt % of a calcined clay were investigated. First, it was found that the slump retaining performance of a common industrial ready-mix type HPEG PCE rapidly decreased when the portion of calcined clay was increased in the blended cement. Furthermore, a combination of the ready-mix HPEG PCE and a retarder (sodium gluconate) which is commonly applied in ready-mix concrete also could not much improve fluidity retention, thus highlighting the difficulty of slump retention for such cements. To solve this problem, a new admixture formulation is introduced based on a combination of a precast type HPEG PCE and a novel PCE-LDH nanocomposite. This approach to improve slump retention was tested on composite cements holding 20-40 wt % of a calcined clay high in meta kaolin content. Mortar tests revealed that the high water-reducing (precast) type HPEG PCE and the PCE-LDH nanocomposite work synergistically and can achieve a significant improvement in fluidity retention of such calcined clay blended cements. A mechanistic investigation revealed that the PCE which was intercalated in between the [Ca2Al(OH)6]+ main layers of the PCE-LDH nanocomposite is released gradually from the mixed metal hydroxide via anionic exchange with sulfate anions present in the pore solution This way, an extended workability time was achieved in the mortar.
Category: alcohols-buliding-blocks, Sodium Gluconate is the sodium salt of gluconic acid with chelating property. Sodium gluconate chelates and forms stable complexes with various ions, preventing them from engaging in chemical reactions.
Sodium gluconate is an organic sodium salt having D-gluconate as the counterion. It has a role as a chelator. It contains a D-gluconate.
D-Gluconic acid sodium salt is a glycol ether that is used as an injection solution. It has been shown to have antibacterial efficacy against wild-type strains of bacteria such as Escherichia coli, Pseudomonas aeruginosa, and Staphylococcus aureus. The in vitro antimicrobial action of D-gluconic acid sodium salt was found to be due to its ability to inhibit bacterial growth by interfering with the synthesis of DNA. D-gluconic acid sodium salt also has been shown to have antihypertensive effects in rats through the inhibition of angiotensin II type 1 receptor (AT1) signaling pathway and erythrocyte proliferation. This drug also has been shown to bind benzalkonium chloride and x-ray diffraction data show that it is crystalline in nature. The analytical method for determining the concentration of D-gluconic acid sodium salt is by electrochemical impedance, 527-07-1.
