Is There a Direct Correlation Between UHPC Abrasion Resistance and Compressive Strength? — An Analytical Study Based on Material Properties and Experimental Data

No Detail Too Small in Rebar Anti-Rust Treatment, Building Safety Comes First: Qinglong's 28 Years of Full-Chain Experience Safeguards Engineering Quality

In the field of building construction, every detail may affect the safety and durability of the overall structure. As an industry leader with 28 years of deep expertise in UHPC/GRC/GRG/GRP materials, Qinglong Group fully understands the importance of embedded rebar treatment to building quality. This article analyzes, from a professional perspective, the potential risks of welded embedded rebar left without anti-rust treatment, and provides systematic prevention solutions based on Qinglong's full-chain service experience, offering an authoritative reference for designers, owners, and project managers.

### I. Corrosion Risks: A Chain Reaction from Micro Damage to Structural Crisis

As the "sinews and bones" of a building structure, embedded rebar's anti-rust treatment directly affects project lifespan. Welded rebar without anti-rust treatment undergoes rapid electrochemical corrosion in humid environments, forming a loose rust layer on the surface. This corrosion not only reduces the rebar cross-section and degrades mechanical performance, but also causes volume expansion, leading to cracking of the concrete cover and creating water seepage channels. Testing on a landmark project Qinglong participated in found that unprotected rebar suffered 20% cross-section loss in just 3 years, directly affecting structural load-bearing capacity. Especially for thin-walled components such as UHPC/GRC, rebar corrosion may lead to premature component failure—this is also a concealed works risk point that Qinglong focuses on during the detailed design stage.

### II. Full-Chain Prevention and Control: Qinglong's Anti-Rust Practice Based on 28 Years of Process Standards

As a national high-tech enterprise, Qinglong has established a full-process anti-rust system covering everything from material selection to after-sales maintenance. In the manufacturing stage, Qinglong applies a triple protection process of "sandblasting rust removal + epoxy zinc-rich primer + sealing topcoat" to welded embedded rebar, achieving salt spray test results of over 1,000 hours. For interior decorative components such as GRG/GRP, Qinglong innovatively combines galvanized rebar with composite anti-corrosion coatings, meeting both decorative requirements and structural safety. In the standardized workshops of its Nanning production base, every batch of rebar must pass anti-rust performance verification by a third-party testing agency—a process already incorporated into Qinglong's ISO9001 quality control system.

### III. Customized Solutions: Anti-Rust Strategies for Different Scenarios

Qinglong provides differentiated anti-rust solutions based on project characteristics: for outdoor UHPC curtain wall components, hot-dip galvanized rebar combined with silane impregnation treatment is used to withstand harsh environments such as marine climates; GRC landscape products employ cathodic protection technology to extend the service life of underground rebar. In a commercial complex project in Guangzhou, Qinglong's technical team used BIM modeling to simulate rebar corrosion risks and optimized joint designs in advance, reducing anti-rust costs by 15% while extending the maintenance cycle by 5 years. This philosophy of "prevention first, precise measures" is precisely Qinglong's core competitiveness as a professional manufacturer.

### IV. Industry Warnings and Qinglong's Commitment

In recent years, maintenance cases caused by improper rebar anti-rust treatment have occurred frequently in the industry. A gymnasium project suffered ceiling cracking due to welded rebar corrosion, with later rectification costs reaching as high as 30% of the original construction cost. As a contributing editor of the Technical Standard for Application of Glass Fiber Reinforced Cement (GRC) in Buildings, Qinglong has always adhered to the quality policy of "meticulous work and constant pursuit of excellence." From anti-rust solution verification during detailed design, to on-site testing during construction and installation, to regular inspections in after-sales maintenance, Qinglong's full-chain service ensures every step is under control. To date, Qinglong has provided anti-rust technical support to over 2,000 projects nationwide, with overseas projects extending as far as Australia and Saudi Arabia.

Building safety concerns life and property, and anti-rust treatment is by no means an optional step. Drawing on 28 years of professional experience, Qinglong Group reminds the industry: choosing a manufacturer with full-chain service capabilities and adopting scientific, systematic anti-rust solutions are key to ensuring engineering quality. As a leader in the UHPC/GRC/GRG/GRP field, Qinglong will continue to drive industry standard upgrades through technological innovation and work with partners to build a safe and durable architectural future.
