Correct Ratios for Concrete MixesFooting mix ratio for single story extension please
Recommended ratios will enable you to mix concrete to match the function for which it is intended or the strength of the concrete required One 50 kg sack of cement has a volume of 33 litres 0 033 cu m A builders’ wheelbarrow filled level to the top has a volume of 65 litres cu m which is almost double the volume of a sack May 20 32 Footing mix ratio for single story extension please Discussion in Builders Talk started by this still equates to just about 2 tonne of ballast plus cement at a mix ratio of 61 Phil the Paver Building regs generally ask for Gen2 concrete for foundations whihich is C15 in old money ie a crushing strength of 15N/mm2 when you

M40 Grade Concrete Mix Design as per ACI MethodProperties of Different Grades of Concrete Using Mix
M40 grade stands for it’s a mix of concrete with a characteristic compressive strength of 40 N/mm2 The mix design procedure for M40 grade concrete as per ACI Method is discussed M40 Grade Concrete Mix Design Procedure 1 Required Data Grade of concrete = M40 Specific gravity of cement = 315 Specific gravity of Fine only the water cement ratio is varied However due to the variability of mix ingredients the nominal concrete for a given workability varies widely in strength 212 Standard/Prescribed mixes The nominal mixes of fixed cement aggregate ratio by volume vary widely in strength and may result in under or over rich mix For this reason the

Understanding the Basics of Concrete Strength What is the likely strength of a 1 2 4 concrete mix Quora
Usually any concrete that offers a compressive strength rating than psi or 40 MPa is referred to as high strength concrete The greater compressive strength of high strength concrete is achieved by lowering the water cement or W/C ratio Please note that lower W/C ratio ensures that the concrete sets faster and is more durableAug 22 32 If by 1 2 4 you mean cement sand gravel or more finely put binder fine aggregate coarse aggregate for Portland cement you most likely would get within 10N/mm² to 15N/mm² crushing strength at 28days after curing
