Brucite powder concrete: frontier exploration of performance tests and engineering applications

As a new type of building material, brucite powder concrete has attracted widespread attention from researchers and engineers in recent years due to its unique performance advantages. The following is an overview of some key points about the performance test and engineering application of brucite powder concrete:

Performance test

1. Basic mechanical properties: The mechanical properties of brucite powder concrete are the basis for evaluating its application potential. Tests usually include the determination of compressive strength, flexural strength, elastic modulus, etc. to compare its differences with traditional concrete. The addition of brucite powder may affect the early strength development of concrete, but it can usually improve its later performance, such as improving long-term strength and durability. 2. Durability test: Durability is a measure of the ability of concrete to maintain its performance under harsh environmental conditions. The durability test of brucite powder concrete includes tests such as impermeability, resistance to freeze-thaw cycles, resistance to chloride ion penetration, and resistance to sulfate erosion. Because brucite powder has a certain alkalinity, it can neutralize the acidic substances in concrete and help improve the corrosion resistance of concrete. 3. Fatigue performance: Fatigue performance is particularly important for structures that bear repeated loads, such as bridges and roads. The test will simulate actual working conditions, conduct fatigue life tests, and evaluate the performance of brucite powder concrete under repeated loads. Studies have shown that the addition of brucite powder may improve the fatigue resistance of concrete. 4. Shrinkage and creep: The shrinkage and creep characteristics of concrete affect its dimensional stability. The shrinkage rate and creep of brucite powder concrete are also important test items, which are related to the long-term stability of the structure.

Engineering Application

1. Infrastructure construction: Due to its improved mechanical properties and durability, brucite powder concrete has begun to be used in infrastructure projects such as roads, bridges, and tunnels, especially in places where crack resistance and durability need to be improved. 2. Environmental remediation projects: The alkalinity of brucite powder can neutralize pollutants in acidic soil or water. Therefore, brucite powder concrete also shows application potential in some environmental remediation projects, such as wastewater treatment and soil improvement. 3. Building structure: In the load-bearing and non-load-bearing structures of buildings, the use of brucite powder concrete can improve the overall durability and service life of the structure, especially in corrosive environments such as the seaside or near chemical plants. 4. Rural roads: Due to its good cost-effectiveness and construction convenience, brucite powder concrete has also been explored and applied in rural road projects, which helps to improve the quality and durability of rural roads.

Performance tests and engineering applications of brucite powder concrete show that it is a potential building material, especially in improving the durability, mechanical properties and environmental performance of concrete. With the deepening of relevant research and the accumulation of engineering practice experience, the application scope of brucite powder concrete is expected to be further expanded.
