What Is Calcium Carbonate? What Is Calcium Carbonate Use for in Construction? Calcium carbonate (CaCO₃) is a versatile mineral compound widely used in construction as a functional filler, strength enhancer, and sustainability driver. Among its most common forms is finely ground limestone powder, sourced from limestone, marble, or industrial byproducts. This material alone accounts for over 200 million tons of annual consumption in building materials, powering innovations in coatings, concrete, wall panels, and synthetic stone. Calcium Carbonate in Architectural Coatings: The Science Behind Wall Aesthetics As a key functional filler, calcium carbonate dominates architectural coatings, improving both performance and cost-efficiency. Key Benefits: Enhances hiding power, abrasion resistance, and surface smoothness. Reduces VOC emissions and material usage. Case Studies: Nano CaCO₃ in Nippon Paint’s ‘Odorless 120’ series: 80-100nm particles boost hiding power by 30%, cut coating usage by 18%, and achieve VOC <10g/L (French A+ certified). Three Trees’ Graphene-Modified CaCO₃ Coating: Reduces thermal conductivity by 40%, winning the 2023 Geneva Invention Award. Market Impact: China’s architectural coatings consume over 6 million tons of CaCO₃ annually, with premium products featuring 35-45% filler content and a 9.2% annual growth rate. Calcium Carbonate in Ready-Mix Concrete: Balancing Strength and Sustainability In concrete, CaCO₃ acts as a microfiller and aggregate modifier, optimizing multi-dimensional performance. Technical Advantages: Fills cement particle gaps to enhance density, impermeability, and compressive strength. Reduces carbon footprint via partial cement substitution. Innovative Formulations: China National Building Material Group’s C80 High-Strength Concrete: 10% cement replaced by CaCO₃ micropowder (450m²/kg surface area) boosts strength to 92MPa and cuts carbon emissions by 18kg/m³. China Resources Cement’s Hong Kong-Zhuhai-Macao Bridge Project: CaCO₃ nucleation activation technology achieves ±15-minute setting time control, chloride ion diffusion coefficient ≤1.8×10⁻¹²m²/s, and 7.3% cost savings.

This article details the top five technical requirements for precipitated calcium carbonate (PCC), covering chemical composition, physical properties, and thermal – chemical stability. It explains how purity, impurity control, particle size, and other factors impact PCC performance. Additionally, it introduces Jintai, a renowned manufacturer, whose PCC products adhere to these requirements for diverse industrial applications.
Light Calcium Carbonate (Precipitated Calcium Carbonate) has evolved from a conventional filler to a multifunctional “performance modulator.” With ongoing innovations in functionalization and green manufacturing, PCC continues to redefine material science boundaries, driving efficiency and sustainability across industries.
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.
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.
