how much tensile strength of M20 grade concrete at 28 Days
M20 - 6.20bags
To calculate the amount of sand and metal (aggregate) in M10 and M20 grades of concrete, you first need to determine the mix ratio. M10 is typically a 1:3:6 ratio (cement:sand:aggregate) and M20 is a 1:1.5:3 ratio. For a given volume of concrete, calculate the total parts in the mix, then divide the total volume by the sum of the parts to find the volume of each component. Finally, multiply the volume of sand and aggregate by their respective mix ratios to find the quantities needed.

95 miles taking this route:Take M25 (E) GATWICK (to M20), from Woking, to M20 towards the CHANNEL TUNNEL and DOVER, via M26 (@ JCT 5).Take M20 & A20 to Dover.
M20 give you strength of 20Mpa and M25 give you strength of 25 Mpa after 28 days of curing.
M20 Mrefers to mix and 20 refers to 20 n/mm2 strengh and M200 mix 200n/mm2
An M22 'rockcrusher' transmission is far noisier than an M20 due to the straight cut gears.
