1:1:2 (1 cement: 1 sand: 2 coarse agregate)
proportion of M30 Grade of concreete is 1 :.5 :1 .
we use M30 grade concrete commercial slabs like shopping malls . college buildings
The proportion of the bed mortar should be 4:1 for the sand : cement.
m-30 1:1.67:2.84,
The ratios of cement to sand to aggregate for the different grades of concrete are as follows. M10 has a ratio of 1:3:6. M15 has a ratio of 1:2:4. M20 has a ratio of 1:1.5:3. M25 has a ratio of 1:1:2, but M30 has no set ratio. It is a designed mixture to achieve the stress tolerance desired.
1:1:2
1:1:2 Hope it helps
M30 mix should be a mix design in laboratory with the available raw materials that is used in the preparation of concrete. The aggregates, sand have different compressive strength, water absorption and these values are used in mix design.
How should I know ;P
The mix proportion for M40 concrete is 1:1.65:2.92W/C ratio = 0.4The design calculation is as per IS mix design
proportion of M30 Grade of concreete is 1 :.5 :1 .
There is no fixed rule for this. If manual mix, cement content shall vary between 350 ~ 400 Kg / M3. Where as for Design mix (RMC), the cement content is decided by the supplier based on lot of other parameters and achieve the desired strength in 3, 7, 15 & 28 Days. Also PFA (Portland Fly Ash) shall also be added to some extent to arrive the desired strenth. The Cement & Fly Ash content shall be 300 / 80 kg per M3, to achieve the desired strength.
Define symmetry and proportion. Why are they important to artistic design?
It is pictures.
The ratio of M30 to WHAT!
Proportion in design will relate to the size of the furniture chosen for a room for example. A castle with huge rooms will require much larger pieces of furniture than a small cottage for a couple.
