replacement of cement with red mud and replacement of fine aggregate with quarry dust

ABSTRACT

The Bayer Process for the production of alumina from Bauxite ore is characterized by low energy efficiency and it results in the production of significant amounts of dust-like, high alkalinity bauxite residues known as red mud. Currently red mud is produced almost at equal mass ratio to metallurgical alumina and is disposed into sealed or unsealed artificial impoundments (landfills), leading to important environmental issues. It comprises of oxides ....etc

Abstract

The high cost of conventional construction material affects economy of structure. With increasing concern over the excessive exploitation of natural aggregates, synthetic lightweight aggregate produced from environmental waste is a viable new source of structural aggregate material. The uses of structural grade lightweight concrete reduce considerably the self-load of a structure and permit larger precast units to be handled. Recently in the environmental issues, restrictions of local and natural access or sources and disposal of wast ....etc

the coconut shell powder when used to replace the fine aggregate partially in the concrete mix; is degradable. what admixtures were used to prevent this? the fineness and specific gravity is also low. what is the size of the coconut shell powder used? ....etc

The fine aggregate is to be replaced with wooden powder and waste plastic. Two separate concrete blocks are to be made with and without the replacement of waste materials. Initially 10 - 15% of waste material has to be replaced and the two blocks are attempted for the crushing load. Based on the results the wastage content will be increased. Now the problem is that, if we can't get such a better result, we can't understand how to go ahead and how to collect the waste materials and if in case is there any chance of replacing any other material. ....etc
