We are using this formula of concrete mix ratio for many proposes in construction industries. There are many terms like, concrete mix ration for foundations or concrete mix ratio by volume, etc.
How Much Concrete Mix Ratio Do I Need??? Today here we see some of interesting facts and figures about ratio specifications. As a person of construction industries, i think this beautifully carved out concrete specification texture, in terms of facts and figures, you like it. Strong Concrete Mix Ratio for Concrete Grade. Every Concrete mix have a particular grade.
So, what is a Concrete Grade? Or What is the meaning of M15 M20 M10 concrete? Here is the simplest term of your question: M10 M15 M20 etc. Are all grades of concrete in the Indian Standard issued by Bureau of Indian Standards. The ‘M’ denotes ‘Mix’ followed by a number representing the compression strength of that mix in N/mm^2. A mix is a specific ratio in which cement, fine(sand) and coarse aggregate(gravel) are mixed.
Concrete Materials Calculators. Volume after being mixed to make concrete. Calculator are provided for a general mix and a paving mix, the different ratio of.
• M5 = 1:4:8 • M10= 1:3:6 • M15= 1:2:4 • M20= 1:1.5:3 • M25= 1:1:2 Clear Mix Ratio Cover to Main Reinforcement. Concrete cover for reinforcement is required to protect the rebar against corrosion and to provide resistance against fire. The thickness of cover depends on environmental conditions and type of structural member. The minimum thickness of reinforcement cover is indicated in the drawings, or shall be obtained from the relevant code of practice. Below are the specifications for reinforcement cover for different structural members in different conditions. • FOOTINGS: 50 mm • RAFT FOUNDATION.TOP: 50 mm • RAFT FOUNDATION.BOTTOM/SIDES: 75 mm • STRAP BEAM: 50 mm • GRADE SLAB: 20 mm • COLUMN: 40 mm • SHEAR WALL: 25 mm • BEAMS: 25 mm • SLABS: 15 mm • FLAT SLAB: 20 mm • STAIRCASE: 15 mm • RET.

Whether you are planning on re-paving your driveway, installing a footpath, building a patio, or even making a plant box, the one thing that these common DIY projects is that they all involve concrete. By definition, concrete is the combination of a binder which is cement, fine aggregates such as sand, and coarse aggregates like gravel. But even though you know what makes up the composition of concrete, that does not mean you can create an effective concrete mixture just by guessing what amounts of which ingredients goes where. There is actually a concrete mix ratio, a recipe if you will, that ensures that the concrete you create is as strong enough for your intended purposes.
Otherwise, you could end up with concrete that is too brittle, or too dense, for your needs. This error, depending on your specific task, could prove to be catastrophic in the end. Concrete Components Cement – This is the binding material that attaches all of the other components in the concrete altogether. There are different kinds of cement being manufactured today, but for ordinary household DIY projects you will mostly be using Ordinary Portland cement, or OPC. You may also come across white Portland and masonry cement is some projects as well.
Aggregates – The aggregates are the components that actually give body and strength to the entire concrete mix. Fine aggregates include sand and fine pebbles, while coarse aggregates include large pebbles, rocks and gravel. You will always use coarse aggregates when mixing concrete, the size of the coarse aggregates you need to use will depend highly on how you will be using the concrete; if you are planning on exposing the concrete on extremely high compressive forces, like a driveway, then you need to use larger size diameter aggregates like gravel for the job. Water – The cement needs water to activate and start hardening. You need to use just enough water to complete wet all the cement in the mix, put too much and the concrete will take a long time to dry and cure, put too little and there will be patches of unmixed cement and gravel in between the concrete which will greatly decrease its strength.
