Secondary aluminum ash (SAA) is a type of common solid waste which leads to pollution without treatment. Due its chemical reactivity, the application SAA reactive powder concrete (RPC) may help solidify this while increasing performance. However, RPC usually in active service when used with steel bars. NaCl can corrode bars reinforced coastal environment. In study, corrosion resistance was inve...

micro silica (ms) is an extremely fine, spherical powder that is used as an additive for improving concrete performance. it is obtained as a by product of silicon metal and ferrosilicon alloy production.  due to its pozzolanic nature, micro silica can be used to enhance the qualities of both  fresh  and  hardened  concrete. addition of micro silica into the concrete as a cement replacement, dec...

Experiences in the development of Ultra High Performance Concrete found a very high flowability in concrete with low water powder ratio. Because of the high viscosity of the cement paste, compaction was necessary. To improve the compaction characteristics of the concrete the idea of adding coarse aggregate was developed. The first tests showed a good workability of the fresh concrete and a good...
