Q:

What is the mixing ratio for stucco?

A:

Quick Answer

The mixing ratio of stucco is to use at least 3 cubic feet of plaster per bag of cement for the scratch coat and a maximum of 5 cubic feet per bag of cement for the brown coat. Water is added to the mixture as needed.

Full Answer

The scratch coat is added first and is the thickest of the coats, normally around 1/2 inch. The brown coat is then added, building the thickness to 3/4 inch. The last coat of stucco applied is the finish coat, manufactured stucco, which is premixed and requires only water. The three layers require a minimum thickness of 7/8 inch over frame construction.

  • Q:

    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.

  • Q:

    When would it be necessary to use rebar in concrete?

    A:

    Rebar provides concrete with significantly more strength than it otherwise has, especially in the area of tensile strength, which makes it necessary for concrete used in infrastructure subject to heavy loads and stress. Rebar, or reinforcing steel, significantly increases the ability of concrete to handle loading pressure and stress. Reinforcing steel is much more flexible and withstands more tension than concrete, making it an ideal additive for concrete that must hold high weights or endure significant amounts of stress.
