In modern large-scale infrastructure construction, from towering hydroelectric dams to bridge piers spanning rivers and seas, from nuclear power plant containment vessels to the thick foundations of skyscrapers, large-volume concrete structures are ubiqui
Concrete, as the most basic material in modern construction, is widely trusted for its strength and stiffness, yet it always faces a hidden enemy—shrinkage.
In engineering scenarios such as industrial plants, bridge bearings, heavy equipment foundations, and rail transit, concrete structures often endure continuous heavy loads or high-frequency mechanical vibrations.
. High-strength repair grouting mortar—a dry powder material composed of polymers, ordinary silicate cement, ultrafine aggregates, expansion agents, and various special admixtures—is becoming a key technology in modern structural repair due to its superio
Lightweight porous aggregate, an artificial aggregate made from inorganic minerals through high-temperature processing, has found a delicate balance between the seemingly contradictory demands of weight reduction and load-bearing capacity thanks to its un
. Traditional repair methods often only address the symptoms, not the root cause. Concrete protective repair materials, through intelligent design at the microscopic scale, achieve a leap from "passive covering" to "active repair."
