This type of hardener typically consists of high-quality Portland cement, selected non-metallic wear-resistant aggregates (such as quartz sand, copper ore sand, etc.), and various chemical admixtures. Its principle of operation involves applying the hardener as a dry shake onto the surface of freshly poured concrete that has not yet fully cured. Subsequently, through mechanical means such as troweling or power floating, it is integrated with the concrete's surface layer, forming a more durable, wear-resistant, and dust-proof surface that significantly enhances the floor's abrasion resistance and scratch resistance. This makes it highly suitable for use in industrial environments with high traffic and heavy loads.
