lime to sand ratio = 2 / 5 17 bags of lime * 5 / 2 = 42.5 bags of sand
2/5 = 17/x (17 times 5) = 2x (17 times 5) divided by 2 = x 85/2 = x 42.5 = x
5/2 x17 = 42.5 bags of sand
normally a 4 20mm Ballast mixture to at least one million Cement ratio is enough. Works supervised by employing Architects/ development surveyors would require a cube or Sphere try. these try the crushingpersistent of the Concrete at an analogous time as cured for a era of time. the final way is to reserve in a waiting blend concrete to the comprehensive of cubic meter required, this would allow a non-supply up skip with out jointing.
