Study of the Microstructure of Industrial Residues and its Application in High Performance Concrete

Article Preview

Abstract:

Along with the rapid development of China and its eye-catching economic take-off, industrial production has brought about increasingly enormous negative impact. Industrial residues (coal ash, iron-ore slag, phosphorous slag and ganister sand) have accumulated in large quantities, thus severely contaminating the environment and greatly restricting the sustainable economic development. This paper conducts research on microstructure of the industrial wastes that are massively applied in domestic architectural material industry, such as coal ash, (S95S105) slag powder, S75 phosphorous slag, micro-bead (ultra-fine coal ash) and the micro ganister sand so as to analyze its size distribution and particle appearance and introduce its functions and effect in concrete and other cement products.
