The long-term benefits of the new generation of sponge hardeners in the maintenance of public facilities: reducing maintenance frequency and improving service quality
Introduction
With the acceleration of urbanization, the maintenance and management of public facilities have become an important part of urban management. Public facilities, such as roads, bridges, squares, etc., are exposed to the natural environment for a long time and are subject to erosion by various physical, chemical and biological factors, resulting in a gradual decline in their performance, an increase in maintenance frequency, and a decline in service quality. To meet this challenge, a new generation of sponge hardener came into being. This article will discuss in detail the long-term benefits of the new generation of sponge hardeners in the maintenance of public facilities from the perspective of chemical experts, including reducing maintenance frequency and improving service quality.
Definition and Principle of Sponge Hardening Agent
Definition
Sponge hardener is a chemical additive that improves the hardness and durability of materials through chemical reactions or physical actions. It is widely used in building materials, road engineering, bridge maintenance and other fields, and can significantly improve the compressive strength, wear resistance and aging resistance of the materials.
Working Principle
Sponge hardener mainly works in the following ways:
- Chemical Reaction: The hardener reacts chemically with certain components in the material to produce more stable compounds, thereby improving the hardness and durability of the material.
- Physical filling: The tiny particles in the hardener fill the pores in the material, reducing defects inside the material, and improving the density of the overall structure.
- Surface Modification: The hardener forms a protective film on the surface of the material to prevent the external environment from eroding the material and extend the service life of the material.
The characteristics of the new generation of sponge hardener

The new generation of sponge hardeners show higher efficiency in improving material hardness and durability. By optimizing the formulation and process, hardeners can significantly improve the performance of the material in a short period of time.
Environmental
Compared with traditional hardener, the new generation of products is more environmentally friendly. It uses non-toxic and harmless raw materials, which reduces harm to the environment and the human body, and is in line with the development trend of modern green chemistry.
Veriodic
The new generation of sponge hardener can not only improve the hardness and durability of the material, but also has various functions such as waterproof, mildew, and corrosion protection, which can meet the maintenance needs of different public facilities.

Long-term Benefit Analysis
Reduce the maintenance frequency
With the use of a new generation of sponge hardener, the maintenance frequency of public facilities is significantly reduced. Taking road maintenance as an example, traditional methods require maintenance twice a year, and after using hardener, the maintenance frequency is reduced to once every 3 years. This not only reduces the maintenance workload, but also significantly reduces the maintenance cost.
Improve service quality
The new generation of sponge hardeners can significantly improve the performance of public facilities and extend their service life. Taking bridge maintenance as an example, after using hardener, the structural stability of the bridge is significantly improved, and its service life is extended from 20 years to more than 40 years. This not only improves the safety of the bridge, but also reduces traffic inconvenience caused by maintenance.
Economic Benefits
Although the initial cost of the new generation of sponge hardeners is high, their long-term economic benefits are significant. Taking square maintenance as an example, after using hardener, the maintenance cost was reduced from 500,000 yuan per year to 250,000 yuan per five years, significantly saving maintenance costs. In addition, extending the service life of the facilities also reduces investment in new construction and renovation, further improving economic benefits.
Environmental Benefits
The new generation of sponge hardener uses environmentally friendly materials to reduce environmental pollution. By reducing the frequency of maintenance, waste and emissions generated during construction are reduced, and the environment is further protected.
