Nuvoco Vistas Corp. Ltd., India's fifth-largest cement group in terms of capacity, announces it has been granted a patent for its product, the “Fibre Reinforced Cement Composition”, branded in the market as “Duraguard Microfiber Cement”. The patent, effective from the date of application - April 4, 2018, cites exclusive rights for the next 20 years.
The concept of using fibres for concrete reinforcement emerged in the 1960s. Duraguard Microfiber Cement leverages this historical development to revolutionize the Indian cement market. This fibre-based cement significantly enhances the bonding process, improves crack resistance, reduces permeability, improves impact strength and durability, and delivers a smoother surface finish.
A distinctive feature of Duraguard Microfiber Cement is the visible presence of fibres in the product, which act as micro-reinforcing agents, enabling the cement to withstand seepage, dampness, cracks, shrinkage, and thermal stresses over the years. Manufactured from high-quality clinker with 48-52% Tricalcium Silicate (C3S) and low Tricalcium Aluminate (C3A), the cement contains high-quality electrostatically precipitated dry fly ash, meeting the highest quality standards.
Duraguard Microfibre Cement finds applications in every stage of construction, from laying foundations to plastering and roof-casting, providing long-lasting protection against micro-cracks. As a result, structures benefit from increased service life and reduced maintenance costs.
