In recently years, with the construction industry greatly development, many new type advanced construction concrete mineral making technological process has larger demand.
A famous research aimed at studying the effect of replacing part of portland cement with fly ash and bottom ash, both from municipal solid waste incinerators . Fly ash was subjected to a washing treatment to reduce the chloride content, while bottom ash was subjected to dry or wet grinding underwater. Concretes with addition of different types of ashes, including a traditional coal fly ash (FA), were manufactured. Fresh and hardened properties of the concretes were compared in order to study the advantages and the side effects of each type of addition. Results showed that MSWI bottom ash is potentially attractive as mineral addition for the production of concrete, provided that the risk of entrapment of hydrogen bubbles produced by corrosion of aluminium metallic particles in the fresh concrete is prevented. This could be achieved by wet grinding the bottom ash so that reactions leading to gas development exhaust within the slurry before this is added to the concrete mixture. Nevertheless, when the hydrogen development in the fresh concrete could be avoided, wet ground MSWI bottom showed a good pozzolanic behavior and proved to give a significant contribution to the development of the strength and impermeability of concrete.
Concrete mineral processing plant design practice and control:
New Concrete mineral processing plant design practice and control system Except for adopt the new material bottom ash for concrete making plant, but used many new concrete grinding mill machines in order to control the capability and efficiency.
Our concrete grinding mill which including the concrete TGM series trapezium grinding mill, concrete raymond mill and ball mill, concrete lm vertical mill, concrete HGM Series roller mill and so on.
That all the information about the Concrete mineral processing plant design practice and control.
