# Concrete Mix Design Steps according to IS 456:2000

Data Require – Mix Design of Concrete

### 1. Target mean strenth

fck’= fck+1.65s
table 8 is456:2000

Target Mean Strength- Mix Design of Concrete

### 2. Selection of water cement ratio

table 5 is 456:2000

selection of Water Cement ratio – Mix Design of Concrete

### 3. Selection of water content

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

Selection of water Content – Mix Design of Concrete

### 4. Calculation of cement content

cement content= water content/ water cement ratio

Selection of Cement Content – Mix Design of Concrete

### 5. Volume of coarse aggregate

table 3 is 456

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)

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

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

Result – Mix Design of Concrete
