Calcium hydroxideFresh propertiesCarbonate concentrationThis study represents the fresh state behavior of Na2CO3-activated ground granulated blast furnace slag (GGBS) pastes. Sodium carbonate (NC) is a suitable activator, though with an extended setting time. To accelerate the hydration process, NC was ...
For example, HMB can be prepared as its calcium salt (Ca-HMB) by a similar procedure to that of Coffman, et al. in which the HMB acid obtained is neutralized with calcium hydroxide, and recovered by crystallization from an aqueous ethanol solution. For example, a 95% ethanol solution can...
Among the ions of Cu, the cupric (Cu+2) ion is commonly found in water as a more widespread oxidation state, forming complexes with carbonate (CO3−2) and hydroxide (OH−1) ions. The development of insoluble mineral Malachite with the chemical composition [Cu2(OH)2 CO3] in water ...
Additionally, highly reflective white coverings (albedo near 0.88) based on the usage of calcium hydroxide were created and tested in summer settings versus typical white pavements (albedo near 0.76). The material has an infrared emittance of approximately 0.85. These low-cost, ecologically friendly ...

However, Wang [190] claim that a high calcium ion quantity limits the quantity of hydroxyl ion released during calcium hydroxide dissolution, resulting in a pH drop. Because of the decline in optimum alkalinity for bacterial action, precipitation may be slowed. Calcium ions cannot easily infiltrate...
