Q:

What is the ratio to mix mortar?

A:

The ratio to mix mortar is historically accepted as 1:3 of sand and cement. Mortar is a mixture of cement used in the building trade to hold bricks together.

The type of sand and cement mixture needed will dictate the exact ratio. This varies according to the needs of the task: above ground is 5:1, below ground is 3:1 and internal walls is 8:1. As outlined on diydata.com, an older method of mixing mortar included portland cement, hydrated lime and sand. Newer methods consist of a mixture of masonry cement and fine sand. An incorrectly mixed mortar can effect the durability of the structure being built.

    What's the difference between concrete and mortar?

    A:

    Concrete is thinner, stronger and more durable than mortar; whereas mortar is used as a bonding agent between building materials, concrete is used for structural projects, such as beams or walls. The differing compositions of these materials makes them ideal for different purposes. Concrete and mortar are not used interchangeably without compromising the structural integrity of a building.

    What is the ratio of steel to concrete?

    A:

    The ratio of steel to concrete is 100:130 for 1 cubic meter. The ratio means that for every 130 kg of concrete, 100 kg of steel is needed to support the structure. This is a rule of thumb in civil engineering that must be observed at all times, as failure to observe it renders buildings prone to ductility and cracking.
