What is mixing ratio for concrete grade 30
Why does concrete mix with low water cement ratio resulted in hardened concrete having higher strength than those with high water cement ratio?
The Concrete mixing ratio for M35 grade concrete as per IS Mix design is1:1.6:2.907 (cement:Fineaggregate:Coarse aggregate)The ratio obtained is as per design calculations by considering the grade of aggregates and the type of cement used.The Water/cement ration is 0.43
1:2
A plain concrete with a large ratio aggregate to cement than structural concrete. It is used for filling and not structural duties
M40 Concrete ratio 1:1.65:2.92 (cement:FA:CA)W/C ratio = 0.4As per Indian Standards.
1:4:8
1:1:2
How to mix 4500 psi cement?
the strength of concrete is effected by water /cement ratio as the water/cement ratio increases the strength of the concrete decreases
1:2:41 :2:3
1:2:41 :2:3
The water/concrete ratio, not mixing it well enough, quality of raw materials, the age of the concrete, and the temperature and humidity of the area surrounding the concrete.
1:1.5:3:0.45 (cement,fine aggregate,coarse aggregate, water cement ratio)
There is no set ratio for a concrete requiring a compressive strength of m50. It is usually created according to the factors of the site condition and location.
This information is probably somewhere on the bag.
cemet: sand: Agg=1:1:2 (Nominal Mix) Above answer is not as per engineering standards. For concrete mixing ration in M30 grade concrete, the mix has to be designed after testing all the materials including water in labs. When you go for higher grade of concretes the mix has to be designed , it is the water to cement ratio which has to be monitered for higher grades of concrete
