How To Extend The Service Life Of Inorganic Grinding Stones Through Technology? How Long Is The Maintenance Cycle?

Analysis of Process and Maintenance Cycle for Extending the Service Life of Inorganic Grinding Stones
1, The core method of extending service life through process optimization
Strengthening grassroots treatment
Strength requirement: The strength of the base concrete should be ≥ C25 (according to CECS 400-2023 standard). If the strength is insufficient, GS-101 reinforcement agent should be applied and cured for 7 days.
Flatness control: The error of the 2-meter ruler should be ≤ 3mm. If it exceeds the limit, self leveling repair material should be used to level and maintain for 24 hours.
Moisture content management: If the moisture content at the grassroots level is ≤ 8%, a dehumidifier should be used to reduce humidity and a moisture-proof film should be laid if it exceeds the standard.
Waterproof layer setting: A 20-30mm waterproof layer should be laid in damp areas to prevent water infiltration and hollowing.
Material ratio optimization
Aggregate selection: Priority should be given to using quartz aggregate (Mohs hardness level 7), which has three times higher wear resistance than limestone (hardness level 3) and stronger acid and alkali resistance.
Cement aggregate ratio: strictly mix cement and aggregate in a ratio of 1:3 to ensure structural stability.
Upgrading of the cementitious system: using special cement and polymer modification, the surface hardness reaches 6-7 levels (ordinary cement is only 5-6 levels), and the wear resistance is significantly improved.
Surface treatment process
Grinding accuracy: The final grinding needs to reach 800 mesh or more, and with the help of infiltration curing technology, the surface hardness can be increased to 4-5 levels, and the wear resistance can be increased by 1.8 times.
Seamless pouring: Thoroughly solve the problem of leakage and dirt in the gaps of traditional terrazzo, and extend its service life.
Construction process control
Water cement ratio: strictly controlled between 0.38-0.42 to avoid structural fragility caused by improper proportioning.
Maintenance conditions: The maintenance time should not be less than 7 days, and the ambient temperature should be maintained at 5-35 ℃ to prevent cracking due to temperature differences or dryness.
Construction period: A standard 100 ㎡ project requires 7-10 days (2 days for base treatment, 3 days for pouring, 2 days for polishing, and 2 days for curing) to avoid quality hazards caused by a short construction period.

2, Maintenance cycle and scientific maintenance plan
Daily cleaning
Tool selection: Use a dry mop or oil-free mop to avoid abrasive wear on the surface.
Cleaning agent usage: Use only clean water or neutral cleaning agents, and avoid strong acidic cleaning agents (such as hydrochloric acid) with a pH value<5 to prevent corrosion.
Cleaning frequency: Clean outside of business hours daily, promptly remove dust and small particles to prevent scratches.
Regular maintenance
Crystal surface treatment: Use a floor crystal surface machine once a month in combination with a specialized crystal surface protector to form a translucent protective film, increase glossiness by 15%, and increase stain resistance by 3 times.
Sealing agent maintenance: Use sealing agent every six months to prevent the ground from darkening or scratching, and extend its service life.
Oil stains and pollution treatment
Instant cleaning: Oil stains should be cleaned with a versatile cleaning agent, wiped dry, and rinsed with clean water. After complete drying, subsequent maintenance can be carried out.
Partial repair: If there is damage, inorganic grinding stone special repair materials are used for seamless repair, with a lower cost than overall replacement.
Strengthening protective measures
Entrance and exit management: Place dust removal pads to reduce the entry of sand and gravel, and lower the risk of wear and tear.
Sharp objects prohibited: Avoid using sharp tools such as steel wire balls for cleaning to prevent surface scratches.
Pedestrian flow control: The high flow area adopts ultra hard polishing technology, with a wear resistance of 8 levels and a reduction of 87% in bacterial growth rate.

3, Life extension effect and data support
Theoretical lifespan: High quality inorganic grinding stones can reach over 30 years under ideal conditions, approaching the lifespan of buildings.
Actual test case: The Hangzhou Yuncui Jinlanfu project has undergone third-party testing and has a compressive strength of over 50MPa, with an expected service life of over 30 years.
Maintenance cost comparison: The 10-year comprehensive maintenance cost is 62% lower than traditional terrazzo, and the long-term cost-effectiveness is significant.
4, Operational suggestions
Construction phase: Strictly follow the CECS 400-2023 standard to ensure that the base treatment, material ratio, and construction technology meet the standards.
Maintenance phase: Develop monthly cleaning plans, quarterly crystal surface treatment plans, annual comprehensive inspection plans, and establish standardized maintenance procedures.

Emergency response: Establish a rapid response mechanism for issues such as oil stains, scratches, and hollowing to prevent small problems from escalating into major repairs.
