A typical mixture of concrete will be 10 to 15% cement, 60 to 75% aggregate, and 15 to 20% water.
In this M refer to Maximum compressive strength and 20 refer that concrete that with stand upto 20KN compressive strength.
The compressive strength of M20 concrete at 28 days typically falls in the range of 20 to 25 megapascals (MPa), which is equivalent to 2900 to 3600 pounds per square inch (psi). M20 is a mix designation for concrete, where "M" stands for "mix" and the number 20 represents the characteristic compressive strength of the concrete mix in MPa. Please note that the actual compressive strength of M20 concrete can vary depending on several factors, including the quality of materials used, the water-cement ratio, the curing conditions, and the testing procedures. To ensure the desired strength, it's essential to follow the recommended mix proportions and proper construction practices during the preparation, placing, and curing of the concrete. Additionally, testing of concrete samples is typically conducted in a laboratory environment to determine the 28-day compressive strength accurately.
Nothing. Concrete doesn't come in gallons for measuring. Milk is in gallons.
100 cubic meters.
Digit 30 stands for minimum strength required after 28 days and 20 stands for maximum size of aggregate
That is an area measurement, whereas concrete is measured in volume, typically cubic yards in the US. The costs vary widely based on local availiblity of materials and the type of concrete mix. The national average is about $100 for a cubic yard of concrete.
