Construction industry at present is facing a major hike in material price, especially cement, sand and stone chips. The following document is prepared to highlight the reduction in concrete manufacturing cost upon using Fly Ash (BIS3812). The method of mix design has been done in reference with BIS10262-2009. Hope that any contractor over India will benefit from the given working and follow the suggested method to reduce their construction cost.
This will have the following advantages: (1) Reduction in use of construction materials which are facing scarcity now-a-days, (2) Reduction of construction cost for contractor, (3) Use of fly ash in a effective manner, which are generated as waste product from thermal power plants and various industrial plants, (4) Assisting in scientific disposal of waste product from thermal power plants and various industrial plants.
Assumed parameters for RCC M25 per Cum mix design as per IS10262:2009 :
Exposure= Moderate

Method of concrete placing= Pumping
Grade of cement= 43
Grading zone of sand= Zone 2
Type of aggregate= Saturated surface dry aggregate
Nominal maximum size of aggregate= 20mm
Chemical Admixture (IS 9103)= None
Assumed parameters for RCC M30 per Cum mix design as per IS10262:2009 :
Exposure= Severe

Method of concrete placing= Pumping
Grade of cement= 43
Grading zone of sand= Zone 2
Type of aggregate= Saturated surface dry aggregate
Nominal maximum size of aggregate= 20mm
Chemical Admixture (IS 9103)= None
