Common Challenges
When making decorative concrete blocks, common difficulties include cracking, air bubbles, and surface imperfections. These can arise due to improper mixing, insufficient curing, or poor mold construction.
Innovative Solutions
To address cracking, use a plasticizer in the concrete mix and apply a curing compound to retain moisture. Eliminate air bubbles by vibrating the mold during pouring. Smooth surface imperfections by sanding after removing the mold. For a sturdy mold, employ strong materials like polyurethane or epoxy resin.
