Concrete Mix Design Steps according to IS 456:2000

Mix Design of Concrete

Mix Design of Concrete
Data Require – Mix Design of Concrete

1. Target mean strenth

fck’= fck+1.65s
table 8 is456:2000

Mix Design of Concrete
Target Mean Strength- Mix Design of Concrete

2. Selection of water cement ratio

table 5 is 456:2000

Mix Design of Concrete
selection of Water Cement ratio – Mix Design of Concrete

3. Selection of water content

table 2.. 186ltr
super plasticiser reduce 20% water content

Mix Design of Concrete
Selection of water Content – Mix Design of Concrete

4. Calculation of cement content

cement content= water content/ water cement ratio

Mix Design of Concrete
Selection of Cement Content – Mix Design of Concrete

5. Volume of coarse aggregate

table 3 is 456

Mix Design of Concrete
Coarse Aggregate – Mix Design of Concrete

6. Mix calculation

for1 m3

volume of cement = (quantity of cement/sp gravity)*(1/1000)

volume of water = quantity of water/1*(1/1000)

volume of chemical admixture = quantity of admixture/ specific gr*(1/1000)

sp 2% by mass of cement

volume of all in aggregate = 1m3- b-c-d

quantity of coarse aggregate = e*volume of coarse agg*specific gravity coarse aggregate

quantity of fine aggregate = e*volume of fine agg*specific gravity fine aggregate

Mix Design of Concrete
Calculation – Mix Design of Concrete

Here we get the

Cement content in Kg

Sand Quantity in Kg

Fine Aggregate in Kg

Coarse Aggregate in Kg

Water Content in Litre

Mix Design of Concrete
Result – Mix Design of Concrete
