Abstract:- Aim of the study is to analysis the properties 20 mm aggregates taken as coarse aggregates were
of concrete with adding fly ash. so using this waste in taken from construction site.
road construction can dispose this waste and also Use potable quality of water. It should be free from
beneficial in minimize pollution in environment due to
impurities and harmful ingredients. It should be within
this waste. It saves the cement requirement for the same
strength thus saving of raw material. In present study the tolerable limits specified by BIS
aims preparing concrete by replacement of Ordinary
Portland Cement (OPC) with fly ash . A comparison is III. TEST AND RESULT
made between fly ash and cement properties which are
used as sub-grade, base in Highway construction.

Table 2. Initial setting time of cement concrete Result- Fly ash increased slump values increased. Fly ash also
has not more binding property so slump values increased.

Thus by result it can see that as amount of fly ash
increased in cement, initial setting time also increased and it Table 4. Compressive strength test Result
take more time to settle.
