When it comes to the mechanical performance of terrazzo flooring, the material inherently possesses solid foundational strength. However, its surface remains somewhat brittle and lacks sufficient wear resistance. In demanding work environments, terrazzo floors may struggle to hold up, showing noticeable signs of enamel wear over time.
The application of concrete sealing and curing agents significantly enhances the durability of terrazzo floors. These agents improve wear resistance, compressive strength, and impact tolerance. On average, the compressive strength of cement-based surfaces treated with these agents increases by approximately 27.3%, while their flexural strength rises by more than threefold. This transformation makes terrazzo floors far better suited for high-stress conditions.
From a chemical standpoint, untreated terrazzo floors are vulnerable due to the spacing between gravel and aggregates. This allows acids, bases, water, oils, and other substances to infiltrate and potentially damage the flooring. Conversely, terrazzo floors treated with concrete sealing agents exhibit enhanced chemical stability. They effectively block most external substances, including water, acids, alkalis, oils, juices, dirt, and algae, providing an additional layer of protection.
Terrazzo floors often suffer from poor waterproofing due to numerous pores within their structure. These pores result in a water absorption rate of up to 8%, meaning significant amounts of moisture can seep into the ground during routine cleaning. Concrete sealing agents address this issue by hardening the surface and drastically reducing water absorption. Within 24 hours, the water absorption rate can drop by up to 96%. While not entirely waterproof, this treatment minimizes moisture penetration, making it an ideal choice for projects requiring robust subterranean construction.
In terms of safety, terrazzo floors generally have weak slip-resistance, scoring only around 50 on the friction coefficient scale. In contrast, concrete sealing agent-treated floors offer superior grip, with a dry-floor friction coefficient of 86 and a wet-floor coefficient of 69. Both types of flooring meet the highest standards for fire safety, achieving the A1 classification. Additionally, the use of inorganic conductive phase materials in terrazzo floors ensures effective static dissipation, and the application of concrete sealing agents does not interfere with this property.
Aesthetically, untreated terrazzo floors with a glazed layer boast a glossy finish but require regular waxing to maintain their appearance, adding to maintenance costs. Floors without a glaze appear dull and lackluster, detracting from their visual appeal. Fortunately, older terrazzo floors can be revitalized through concrete sealing agents, restoring their former brilliance without the need for continuous waxing or extensive renovations. This process not only enhances beauty but also prolongs the lifespan of the flooring, offering a cost-effective solution for those seeking to preserve the elegance of their terrazzo floors.
