Considering concrete density = 2400 kg/cum, One bag of cement and other ingredients can produce = 400/2400 = 0.167 Cum of concrete (1:2:4) 01 bag cement yield = 0.167 cum concrete with a proportion of 1:2:4. 01 cum of concrete will require. Cement required = 1/0.167 = 5.98 Bags ~ 6 Bags. Sand required = 115/0.167 = 688 Kgs or 14.98 cft
You may also decide to work in the warmest time of the day, so the concrete is firm enough before the cold. Conclusion. The right composition of your concrete with the materials in the recommended ratio is instrumental in having good concrete. Using a proper mixing technique and helping your concrete cure well will also make the concrete durable.

C25 concrete grade uses. Ordinarily a concrete project will be undertaken using the appropriate concrete grade to save on costs, but also to make sure that any structural features are capable of standing on it safely. This grade of concrete is a safe mix for use in foundations, which means it is strong enough to use for more substantial or more ...
The grade of concrete is also termed as C16/20, C20/25, C25/30, etc. 1MPA = N/mm 2 Several grades of concrete contains various concrete mix proportions or ratios. How to work out the quantities of cement, sand and aggregate in 1m 3 of concrete:-Guess a nominal mix grade of concrete as M20.
C25 Concrete Mix Ratio UK. Depending on the jobs you need concrete for, the right C25 mix ratio could mean everything. Therefore, do be sure to buy concrete supply from a team who can mix you the best quality blends off-site, and who will pump everything through to you on-site. It's a fast, cost-effective and convenient way to make sure you get exactly what you need, when you need it, and ...
6. For all structural elements, M25 grade concrete will be used. However, higher M30 grade concrete is used for central columns up to plinth, in ground floor and in the first floor. 7. Sizes of all columns in upper floors are kept the same; however, for columns up to plinth, sizes are increased. 8. The floor diaphragms are assumed to be rigid. 9.
