The standard mix for Concrete Blocks is 1:3:5, 1 part cement to 3 parts sand & 5 parts stone aggregate, by volume. 1 part cement to 8 parts mixed aggregate is much the same thing. Note that the ratio is different by weight, since the ingredients don't have the same density. Many other mixes are also possible.
On this page, you can calculate material consumption viz., cement, sand, stone gravel for the following concrete mix ratios - 1:1.5:3, 1:2:4, 1:3:6, 1:4:8, 1:5:10. Once, the quantities are determined, it is easy to estimate the cost of a concrete block, driveway, patio, yard or any other structure with the price prevailing in your area.

This hollow Cement Block have open or closed cavity and can be used in the construction of load-bearing and non-load bearing partition walls. Hollow cement blocks have one or more hollow cores. These cores reduce the total cross-sectional area of the block by at least 25 percent. In general, a hollow-core cement block is more than 50 percent solid.
The most commonly used concrete mix design is called a normal-strength concrete, which consists of Portland cement, sand, aggregate (typically gravel or crushed stone), and water. The proportions of these ingredients are typically expressed as a ratio, such as 1:2:3:0.5, which represents the ratio of cement to sand to aggregate to water.
