Why we do multiply 1.54 for dry volume of concrete?
1.54 is a factor that helps us to convert the Wet Volume of Concrete into Dry Volume. So that we can calculate the number of materials in dry condition. 1.54 is nothing but a 54 percent increment of Wet volume of concrete along with Wet Volume. For that, we have to increase the Wet volume to 54 percent.
How do you calculate the volume of concrete mixture?
The prescribed Nominal Concrete Mix Ratio of M20 grade concrete is 1:1.5:3.
- Cement = 1 Part.
- Sand = 1.5 Part.
- Aggregate = 3 Part.
- Total dry volume of ingredients required = 1.57 cu.m.
How many volume of dry concrete is required for 1m3 of wet compacted concrete?
volume of dry concrete =1.54 times volume of wet concrete.
What is volume of cement?
1 bag cement volume in cft:- volume of 1 bag cement (50kgs) is around 1.226 cft (cubic feet). 1 bag cement volume:- volume of 1 bag of 50kg cement is around 1.226 cft or 0.0347m3 and for 1 bag of 25kg cement this will be 0.613 CFT or 0.0174 m3.
What is concrete mix ratio?
In terms of the ratio for concrete, it depends on what strength you are trying to achieve, but as a general guide a standard concrete mix would be 1 part cement to 2 parts sand to 4 parts aggregates. For foundations, a mix of 1 part cement to 3 parts sand to 6 parts aggregates can be used.
Why dry volume of concrete is more than wet volume?
Dry volume of concrete is mixture of cement, sand and aggregate without water in dry condition, their volume is increased by 54\% of wet volume due to presence of air voids between cement, sand and aggregate particles.
Why is concrete volume wet?
When we mix the concrete ingredients in dry conditions, they contain voids in them with loosely filled materials. When we estimate the volume of the concrete structure, we get the volume of the wet concrete. So, we have to convert this into dry mix concrete volume, while batching and preparing the concrete.
Why do we use 53 grade cement?
Initial Strength OPC 53 cement gains faster strength as water is added in cement and achieves 30\% strength in 3 days, 70\% in 7 days, and 100 \% strength at end of 28 days. Therefore, OPC 53 is the grade of cement that is most used in construction where faster concrete is required.
What is the dry volume of 1m3 of concrete?
The dry volume of total materials required is considered as 1.54 times the wet volume of concrete, due to voids present in sand and aggregates in dry stage. Therefore, for our calculation, we will consider the total volume of materials required as 1.54 m 3 for 1 m 3 of wet concrete.
How many bags of cement are required for 1m3 of concrete?
Therefore, for our calculation, we will consider the total volume of materials required as 1.54 m 3 for 1 m 3 of wet concrete. Volume of cement required for 1m 3 of Concrete = =0.28 m 3 Then number of bags of cement (volume of one bag of cement = 0.0347 m 3 ) = = 8.07 bags of cement.
How do you calculate the volume of a concrete cube?
Volume of concrete cube = length x Width x Height = 1 x 1 x 1 = 1 m³ (Wet volume) When we convert this wet volume into dry volume, the volume is increased by 54\% of wet volume. ∴ Dry volume = Wet volume + 54\% of Wet volume = 1 + (54/100) x 1 =1 + 0.54 = 1.54
What is the volume of aggregate required for cement to sand ratio?
Since we know the ratio of cement to sand (1:2) and cement to aggregate (1:4) Volume of Aggregate required would be = 0.035*4 = 0.14 cubic meter (cum) To convert Sand volume into weight we assume, we need the dry loose bulk density (DLBD).
