دوده سیلیسی (۹۹ درصد خالص): مقاومت بتن در برابر خمش را شارژ می کند
Why Concrete Needs to Bend, Not Break Concrete forms the skeleton of modern construction. Yet standard mixes often crack under bending stress. Think of bridges swaying under traffic or warehouse floors bearing heavy loads. That’s where flexural strength matters. High-purity silica fume (SiO₂ ≥99.0%) offers a powerful upgrade. This ultra-fine powder, often called microsilica, dramatically …
