Zrete Heat-Resistant Concrete is designed for high-temperature environments (200–900°C), offering outstanding thermal stability, abrasion resistance.
Product Introduction
Zrete Heat-Resistant Concrete is a thermal protective cementitious grout designed for extreme service conditions. Whether you're reinforcing a tunnel, lining a furnace, or upgrading aerospace or civil fire barriers, this concrete ensures stability, and resilience from 200°C up to 900°C. It resists surface cracking, maintains over 50% of its strength at elevated temperatures, and provides a dense, durable, water-resistant matrix.
Its sustainable composition also allows industrial waste materials to be reused, contributing to greener infrastructure projects.
