A binder added during concrete manufacturing to increase the strength, durability and watertightness of concrete structures and improve workability and economy.
| Overview | ￭ Luge-S4 is a high-performance cement that shows practical strength within a short time (4 hours), and exhibits excellent performance in emergency construction, maintenance, and low temperature environments. |
|---|---|
| Features | ￭ Practical strength develops 3 hours after placement ￭ Practical strength develops 3 hours after placement ￭ Condensation time can be adjusted according to season and site conditions ￭ Production of stable quality products using a zero-gravity mixer |
| Usage | ￭ For emergency repair of concrete pavement ￭ Repair and reinforcement of bridge expansion joint equipment ￭ For emergency maintenance such as railways, bridges, runways, etc. ￭ For low temperature emergency maintenance ￭ For mechanical equipment foundation work |
| Overview | ￭ Luge-S12 is a high-performance cement that shows practical strength within a short time (12 hours), and demonstrates excellent performance in emergency construction, maintenance, and low temperature environments. |
|---|---|
| Features | ￭ 1 day after casting Normal Portland cement develops 7-day strength ￭ It is suitable for Korean-Chinese construction because it has excellent strength development at low temperatures. ￭ Excellent bleed prevention effect due to short initial curing time ￭ A material that is convenient for emergency maintenance work and has excellent workability |
| Usage | ￭ For emergency maintenance of concrete roads and bridges ￭ On the gravel road below the railroad rails such as railroads and subways ￭ Improvement and emergency maintenance for midwinter construction |
| Overview | ￭ It develops strength faster than crude steel cement and shows 7-day strength of normal Portland cement (1 type) after 1-day curing, and is used for emergency maintenance work and winter work. |
|---|---|
| Features | ￭ High early strength ￭ It shows excellent strength even at low temperatures and can be used for Korean-Chinese construction. ￭ Since the curing time is short, bleeding can be effectively prevented. |
| Usage | ￭ For emergency maintenance of concrete roads and bridges ￭ Railroad, subway, etc. Railroad rail sewage gravel Road improvement and emergency maintenance ￭ For floor foundation work for hardware installation ￭ For midwinter construction |
| Overview | ￭ Since it has a high degree of powder, it has excellent permeability to fine cracks, and is a cement injection material with excellent durability and strength development. |
|---|---|
| Features | ￭ Fine average particle size and excellent injection characteristics ￭ No effect of contamination on soil or groundwater after injection ￭ Excellent long-term strength improvement effect ￭ Easy to adjust curing time and low bleed rate |
| Usage | ￭ Tunnel wall lining and ground reinforcement ￭ Injection into the Dam and bank ￭ Prevention of leachate at waste treatment plants ￭ Prevention of subsidence of ground structures, etc. ￭ Leakage blocking of underground structures |
