Roof Concrete Mix Ratio

This ratio of concrete also gives very high strength of cement concrete and is recommended for following works.

Roof concrete mix ratio.

Example calculation estimate the quantity of cement sand and stone aggregate required for 1 cubic meter of 1 2 4 concrete mix. This type of mix makes the roof slab strong. 702 5 pounds of cement. The concrete mix ratio for m20 grade of concrete is 1 1 5 3 that mean 1 part of cement 1 5 part of sand fine aggregate and 3 parts of aggregate crushed stone in volume and then batched for mixing.

Structure carries in heavy loads. Never ever add excess water to mix concrete. Rounded off it s basically a 1. The lower the w c ratio the higher the concrete strength.

Where cement concrete 1 1 5 3 is used. To know the concrete mix design follow below. 1587 pounds of stone. The mix ratio of 1 2 3 consists of 1 part cement 2 parts sand and 3 parts stone plus some water to make a concrete mix you can use for most any building project.

Labor guideline for steel bars in rcc. To make ease in understanding we are finding the concrete mix design of m20 grade concrete. Concrete mix ratio compressive strength is the most important property of hardened concrete. 1217 pounds of sand.

As long as you re consistent you ll get a good strong mix. When we take concrete mix in a plate it should become like a scoop. If i break the weights down per cubic yard of concrete it comes to. Materials required are 7 nos.

Size of aggregates mm water for dry aggregates liter water for aggregates condition from dry to moist batch liter water for best consistency liter small precast work fence posts poles garden furniture and other work of very thin sections. 2 26 parts stone 1 73 parts sand. 2 concrete mix ratio. In case of single or two story house the ration of concrete mix will be 1 2 4.

Of 50 kg bag of cement 0 42 m 3 of sand and 0 83 m 3 of stone aggregate. It can be measured easily on standard sized cube 15 cm and is often taken as an index of the overall quality of concrete. It means 1 part of cement 1 5 part of fine aggregate coarse sand and 3 parts of coarse aggregate. Water cement ratio theory states that for a given combination of materials and as long as workable consistency is obtained the strength of concrete at a given age depends on the w c ratio.
