Application of calcium carbonate in construction

💎 Calcium carbonate｜The "white gold" of the construction industry, from rough to fine decoration, it all depends on it! 50 cents cost to get 50,000 results!

🌟 6 amazing applications of calcium carbonate in construction

1️⃣ The heart of cement:

▪️ Limestone is calcined into cement clinker, and it is used to build buildings and pave roads! 💪 1 ton of cement ≈ 700kg of calcium carbonate, and your load-bearing walls are all due to it~

▪️ Cold knowledge: The world consumes 5 billion tons of cement every year, which can circle the earth 1,200 times!

2️⃣ Concrete aggregate:

▪️ Crushed into gravel/sand, mixed with concrete to build houses, high hardness and save money! 🏗️ The cost is 30% lower than quartz sand, the secret weapon of the construction site boss~

3️⃣ Wall whitening master:

▪️ Putty powder adds ultra-fine calcium carbonate, and the wall surface is smooth like grinding skin! ✨ It is also used for self-leveling floors, and the rough house becomes minimalist in seconds~

▪️ Pitfall avoidance guide: Choose a fineness of 1250 mesh or above, and there will be no lumps when brushing the wall!

4️⃣ Stone substitute ceiling:

▪️ Artificial marble = 80% calcium carbonate + resin, the price is less than 1/3 of natural stone! 💸 Kitchen countertops and bathroom wall panels are all using it~

▪️ Black technology: Nano calcium carbonate coating, tile anti-fouling ability +200%!

5️⃣ Environmental protection dark horse:

▪️ Calcium carbonate is used to absorb sulfur dioxide in industrial waste gas treatment, the terminator of smog days! 🌍 New low-carbon cement reduces emissions by 30%, and the country is promoting it mandatory~

6️⃣ Aesthetic buff:

▪️ Add calcium carbonate to architectural coatings, waterproof, mildew-proof and color-developing! 🎨 Mediterranean-style white walls and wabi-sabi-style micro-cement all rely on it to maintain their appearance~

🛒 Guide for self-installation party to find bargains

✅ Look for "Guangdong White Calcium": Guangxi/Guangdong calcium carbonate purity>98%, price per ton<500 yuan!

✅ DIY formula: wall repair = calcium carbonate powder + white glue + water, cost 0.5 yuan/square meter!

✅ Lightning protection magnesium carbonate: dripping dilute hydrochloric acid and bubbling is real calcium carbonate (CaCO₃+2HCl→CaCl₂+CO₂↑+H₂O)

🌍 Cold knowledge attack

▪️ The limestone of the Egyptian pyramids contains calcium carbonate, which has been exposed to wind and rain for 5,000 years!

▪️ The Winter Olympics venues use calcium carbonate aerogel, and the thermal insulation performance is comparable to down jackets❄️

▪️ Future technology: self-repairing concrete (calcium carbonate + microorganisms), cracks heal automatically!

❓ Soul-searching question

Are you willing to use artificial calcium carbonate stone instead of natural marble?

🔥 Summary in one sentence

From 50 cents putty powder to 5 million/ton low-carbon cement, calcium carbonate uses "earthy science" to undertake architectural aesthetics - it is the king of cost-effectiveness hidden in reinforced concrete! 🏠✨
