Is Calcium Hydroxide waking up this morning relieved or disappointed at not getting a reminder that she's forgotten he exists?

Nanoparticles with quantum dots for restoring monuments

The fluorescence emitted by zinc oxide quantum dots can be used to determine the penetration depth of certain substances used in the restoration of historical buildings. Researchers from Pablo de Olavide University (Spain) have tested this with samples collected from historical quarries in Cadiz, where the stone was used to build the city hall and cathedral of Seville.

One of the main problems in the preservation of historic buildings is the loss of cohesion of their building materials. Restorers use consolidating substances to make them more resistant, such as lime (calcium hydroxide), which has long been used because of its great durability and high compatibility with the carbonate stone substrate.

Now, researchers at Pablo de Olavide University, in Seville, have developed and patented calcium hydroxide nanoparticles doped with quantum dots that are more effective as consolidant and make it possible to distinguish the restored from the original material, as it is recommended for the conservation and restoration of historical heritage. Details are published in the Construction and Building Materials journal.

There was a time last year — I don’t know if I’m supposed to say anything — but she was dating someone. I’d actually never met this person, but I could just tell every time I would talk to her, she would hunch over. I sent her this picture of her as Quasimodo that I edited. Because I was like, “You cannot turn into Quasimodo for this guy. Every time you say his name, you hunch over.’”

A recipe for concrete that can withstand road salt deterioration

Recycled materials used to make a better concrete mix

Road salt, used in copious helpings each winter to protect them from ice and preserve safe driving conditions, is slowly degrading the concrete they're made of. Engineers have known for some time that calcium chloride salt, commonly used as deicer, reacts with the calcium hydroxide in concrete to form a chemical byproduct that causes roadways to crumble. A civil engineer from Drexel University is working on a new recipe for concrete, using cast-off products from furnaces, that can hold its own against the forces of chemical erosion.

More than 900,000 tons of deicing salt is used each winter in Pennsylvania alone. While winters in the Northeast put pressure on departments of transportation to keep roads clear and deicer is an effective part of that process, it also contributes to the thousands of miles of roads that need to be patched and repaired each year.

Yaghoob Farnam, PhD, an assistant professor in Drexel's College of Engineering and director of the Advanced and Sustainable Infrastructure Materials Research Group, is looking for a solution to this problem in the recipe for concrete. Farnam created a method for using fly ash, slag and silica fume -- leftovers from coal furnaces and the smelting process -- in a new concrete mix that is more durable because it doesn't react with road salt. He recently published his findings in the journal of Cement and Concrete Composites.

Calcium Hydroxide for Water Treatment – Uses, Benefits & Industrial Applications

Calcium hydroxide, also known as slaked lime or hydrated lime, is widely used in water treatment processes to improve water quality and maintain proper pH levels. It helps neutralize acidic water, remove heavy metals, and reduce impurities in municipal and industrial wastewater treatment plants. Calcium hydroxide plays an important role in water purification, sludge treatment, and environmental protection. Vigyan Lime, a trusted manufacturer since 1948, supplies high-purity calcium hydroxide suitable for water treatment and wastewater purification applications.
