The diary of Merer, (found in 2013) did it finally solve the mistery of the Pyramids?

Per the article, the diary logs the transportation, but not use of, limestone.

The author then interjects opinion on what that might have been used for.

If the hieratic portion of the text specifically chronicles them shipping literal cut blocks of limestone, then it's a total fraud. Given Zahi Hawas's involvement, that's not at all hard to believe.

The limestone blocks in the great pyramids are chemically homogenous (meaning they are nearly 100% pure limestone throughout - no variety, no veins of other minerals, etc.). Limestone doesn't exist in this form in nature anywhere on Earth. It had to have been pulverized, perhaps superheated into a "clinker" (easy to do using glass to magnify the sun's rays - and the Egyptians were master craftsmen with glass), then mixed with water to form a slurry & poured like concrete.

People have known this since the 1700s. I'm shocked that the quackademics continue to peddle this fictional mystery (but they most certainly do). BTW, same exact thing with the buildings in Teotehuacan & Sacsaywahmen (sp?). Concreted limestone covered in plaster.

There are mindblowing megalithic cut-stone structures all over the world, but these ain't it.
