Core features:

　　Fast setting, fast hardening, and early strength.

　　1. Ultra early strength feature: This is its most prominent advantage. Its strength within 12 hours to 1 day can reach the same level as the 28 day strength of ordinary cement. This greatly accelerates the construction pace.

　　2. High frost resistance: Due to the rapid development of early strength, even in low or negative temperature environments, its strength can quickly increase, and its ability to resist freezing damage is strong, making it very suitable for winter construction.

　　3. High corrosion resistance: Due to the absence of calcium hydroxide, which is easily corroded by ordinary cement, in its hydration products, it has strong resistance to corrosive media such as seawater and sulfates.

Application scope:

　　The unique properties of sulfoaluminate fast hardening cement determine that it is mainly used in emergency, fast, and special requirements engineering.

　　1. Emergency repair and rapid construction:

　　Military engineering: rapid repair of airport runways, roads, and bridges, requiring the restoration of navigation/opening within a few hours.

　　2. Municipal engineering: rapid repair of highways, urban roads, tunnels, and airports to minimize traffic interruption time.

　　3. Industrial facilities: rapid repair of factory floors and equipment foundations.

　　4. Winter construction and low-temperature engineering: Due to its high early strength and high frost resistance, it can be constructed normally and rapidly develop strength even without or with only simple insulation measures in low-temperature environments ranging from 0 ° C to -10 ° C to -15 ° C.

　　5. Prefabricated components and special mortar: used for the production of prefabricated components that require rapid demolding and improved mold turnover.

　　Used for preparing special dry mix mortars such as quick leak sealing agents and anchoring agents.

　　6. Compensating shrinkage concrete and self stressing concrete: Utilizing their micro expansion properties, they are used to prepare structural self waterproofing concrete, post pouring strips, pipe joints, etc., which can effectively prevent concrete cracking and leakage.
