Sand Raw Materials: More Than You Think!
2025-12-02Sand Raw Materials: More Than You Think! Most people associate sand with beach/river grains, but construction, road, and glass sand comes from diverse sources—far beyond natural quartz sand. Here’s the key breakdown: 1. Natural Sand: Nature’s Gift Formed by long-term natural processes, it has three main types: Quartz Sand: Most common (70% of natural sand use), from quartzite/granite. Hard, wear-resistant (SiO₂-based), ideal for construction/concrete. Feldspar Sand: From feldspar rocks (e.g., orthoclase). Less hard than quartz, red/pink, used in ceramics/glass auxiliaries—more affordable. Limestone Sand: From limestone/dolomite (CaCO₃). Soft, grayish-white, low-cost, for mortar/road bases. Over-mining harms ecosystems; China strictly restricts natural sand extraction. 2. Manufactured Sand: Natural Sand’s Main Replacement Mechanically crushed rock/ore, now mainstream (60% of China’s construction sand): Granite: “Golden raw material”—hard, angular, high compressive strength for high-rises/bridges. Limestone: Economical, abundant—40% of China’s manufactured sand, for ordinary construction/mortar. Basalt: Volcanic rock, wear-resistant—for expressways/airport runways. Slag Sand: Recycled steel mill blast furnace slag—green, enhances concrete density/corrosion resistance (marine/underground projects). Controllable particle size, no ecological damage. 3. Special-Purpose Sand Niche but critical: Glass Sand: High-purity quartz sand (SiO₂ ≥99.5%), impurity-free—core for glass production. Foundry Sand: Zircon/chromite/high-purity quartz sand—heat-stable for metal casting (precision parts). Beauty/Filter Sand: Round, impurity-free quartz/feldspar sand—for scrubs/water filtration….
