無収縮モルタルでコンクリートのひび割れ補修の補修【素人はDIYで水養生】

I'm repairing cracks in the concrete of my parking lot. I used non-shrink mortar to repair cracks in the concrete floor, but it cracked again the next day. Previous video: Repairing cracks in concrete with non-shrink mortar [Amateur DIY thin application]    • 無収縮モルタルでコンクリートのヒビ割れ補修します【素人はDIYで薄塗り】   After uploading my last video, I received some additional advice from a viewer, so I'll try using that advice. This time, I'll be repairing the area using non-shrink mortar again. Before applying the mortar, I chipped, cleaned, and applied a primer to the area. I've included a lot of explanations so anyone can follow along. I'm not very good at a lot of things, but I hope you'll enjoy watching this as a documentary on amateur work. 〇By the way, This time, I water-cured the concrete immediately after pouring. However, a viewer commented that water-curing after the cement has hardened and allowing it to harden slowly will significantly increase its strength. Exposing the concrete to water before it hardens can cause efflorescence, which can reduce the cement's surface strength and lead to a loss of strength. I had already repaired the cracks before receiving that advice, so perhaps I should have delayed water-curing. As for the efflorescence, I'll monitor its progress. 〇Video Contents 1.
