Simply follow the ratios above using the bucket as your measuring tool: one bucket Portland cement, three buckets sand, three buckets aggregate, and one bucket of water. This will not only produce enough mixture for most small home improvement projects but also produce a mixture that can withstand approximately 3000 PSI. Mixing the Concrete
Concrete mix ratios are usually in the ratio format of cement : Sand: Aggregate. For example, if the concrete mix ratio of M20 concrete is 1:1.5:3 then 1 part of cement, 1.5 part of sand and 3 part of aggregate in volume should be taken to produce concrete. Prescribed concrete Mix ratios for all grades of concrete are given below

Thicker concrete for things like foundations and larger mass concrete is usually a 'weaker' mix of 1:3:6 which is one cement, 3 sharp/washed sand and 6 gravel/crushed stone. In all concrete just enough water should be added until the mix folds nicely off the paddles/tines inside the mixer.
After cooling the device, the distance between indicator points is measured again. In a good quality cement, the distance should not exceed 10 mm. Autoclave Test Cement paste (of normal consistency) is placed in an autoclave (high-pressure steam vessel) and slowly brought to 2.03 MPa.
