What is Calcium Carbonate Used for in Construction?
Introduction: The Mineral That Builds Our World Calcium carbonate (CaCO₃), a naturally abundant mineral found in limestone, marble, and marine shells, has been the backbone of construction for millennia. Today, it bridges ancient techniques and modern innovations, offering solutions from high-strength concrete to carbon-negative materials. As the world shifts toward sustainability, calcium carbonate is redefining how we build—stronger, greener, and smarter. Traditional Applications: The Pillars of Construction 1. Cement, Concrete & Asphalt Cement Production: Limestone (CaCO₃) is calcined to produce lime (CaO), a key component of Portland cement. Concrete Enhancement: Adding 10%-15% ultrafine CaCO₃ (particle size <10μm) improves early compressive strength by 8%-12% (Cement and Concrete Research) and reduces shrinkage cracks. Asphalt Optimization: CaCO₃ enhances aggregate adhesion, extending road durability. 2. Functional Fillers & Architectural Solutions Paints & Coatings: Replaces 30%-40% titanium dioxide, achieving >10.000 scrub cycles (ASTM D2486) and reducing costs. PVC Building Materials: 40%-60% CaCO₃ increases rigidity (elastic modulus +15%-25%) in pipes and profiles. Fireproof Boards: CaCO₃-based panels (density <1.5 g/cm³) with Class A1 fire resistance for partitions and ceilings. Innovation Frontiers: Sustainable & High-Performance Solutions 1. Calcium Carbonate Whiskers Micro-Crack Bridging: Adding 1%-2% whiskers (length 1–6 μm, diameter ~1 μm) boosts concrete flexural strength by 30% . Polymer Composites: Increases tensile strength by 54%, ideal for lightweight, high-strength facades. 2. Eco-Technologies Enzyme-Induced Carbonate Precipitation (EICP): Binds loose soils using plant-derived enzymes, consuming 80% less energy than cement grouting . Bio-Concrete: Microbial CaCO₃ mineralization transforms urea waste into 50 MPa-strength materials, cutting cement-related CO₂ by 80% . 3. Carbon-Negative Materials CO₂ Sequestration: Jintai Group’s collaboration with CarbonCure injects captured CO₂ into concrete, reducing emissions by 10% per cubic meter . Why Choose Chinese Calcium Carbonate Suppliers? China produces 65% of global calcium carbonate, offering unmatched advantages: 1. Cost Efficiency & Quality Competitive Pricing: 30-50% lower than EU/US suppliers due…

What is the Use of Ground Calcium Carbonate (GCC) in Coatings? A Comprehensive Guide
Ground calcium carbonate (GCC) is a versatile, cost-effective filler and pigment in coatings, improving opacity, durability, and sustainability. This article examines its role in architectural paints (interior/exterior), floor coatings, waterproofing, and fire-resistant systems. Key topics include particle size optimization, surface modification techniques, and emerging trends like eco-friendly formulations.
What Are the Different Types of Calcium Carbonate?
Calcium carbonate exists as PCC (chemically refined), GCC (mechanically ground), and NCC (nano-engineered). PCC offers high purity for premium uses, GCC excels in cost-sensitive industries, and NCC drives innovation in biomedicine and eco-materials. This guide compares their properties, applications, and selection criteria, empowering industries to optimize performance and cost-efficiency.
Analysis of Calcium Carbonate Surface Modification Technologies
Explore calcium carbonate surface modification technologies across heavy (GCC), light (PCC), and nano grades. Uncover core methods like chemical grafting, plasma treatment, and hyperdispersant strategies, and their high-end applications in automotive, bioplastics, and energy storage.
What is the Difference Between GCC and PCC Calcium Carbonate?
Calcium carbonate, a critical industrial filler, exists in two primary forms: GCC (Ground Calcium Carbonate) and PCC (Precipitated Calcium Carbonate). GCC is mechanically ground from natural limestone or marble, offering cost-effective bulk filling for plastics, rubber, and paper. PCC is chemically synthesized, providing finer particles, higher brightness, and enhanced mechanical properties for premium applications like coatings and adhesives.
