Gravels constitute the majority of coarse aggregate used in concrete with crushed stone making up most of the remainder. Natural gravel and sand are usually dug or dredged from a pit, river, lake, or seabed. Crushed aggregate is produced by crushing quarry rock, boulders, cobbles, or large-size gravel.

Gravel Mix (Concrete Mix) Posted on April 12, 2011 by admin. GRAVEL MIX is a quality blend of Portland cement, graded sand and stone/gravel.

Velay-Lizancos studies concrete and works to make it a more sustainable building material. Concrete, a variable mixture of water, cement paste, and aggregates such as sand and gravel, was invented millennia ago. Since then, it has changed to suit civilizations' evolving needs and available materials.

A small amount of mortar mix or Portland cement can be mixed in with the crushed gravel. I use a concrete mixer. Maybe 2 or 3 shovels full of the cement product per wheelbarrow of stone aggregate. The idea is that the aggregate still needs to drain, but the cement makes it so that it is a little firm so that it cannot erode.

Lets calculate volume of sand and gravel needed to prepare M15 grade concrete. Mix Ratio of M15 grade concrete is 1:2:4. Hence for every 1 part of cement, we have to use 2 part of sand and 4 part of gravel to get M15 ratio concrete. The volume of 50 kg cement bag is 1.25 CFT.
