Warped studs can frequently be returned to original alignment with additional bridging. Headers, lintels, and sills can be returned to horizontal position by proper shimming. |
|
|
True |
|
|
False |
| 20. |
Any major structural repairs or replacements such as the latter should not be undertaken in load bearing walls without first removing the loads from the wall under repair by adequate shoring and jacking. |
|
|
True |
|
|

| 21. |
Some of the advantages of steel framing include: |

|
|

| 23. |
Exterior walls that support loads from floors, roof, and equipment plus their own weight could be classified as: |
|

Weathering may cause damage on mortar joints under the best conditions. Poor mortar mixes are usually at fault. When the face of the masonry walls is marred by stains and efflorescence. Impure water containing acids or organic matter and improper sand in the mortar mix not only cause stains through bleeding( spillage of water over a masonry surface during construction of curing), but also accelerate weathering of the mortar joints. |
|
|
True |
|
|
False |
| 25. |
Mortar preparation in a brickwork can be a mixture of 1 part Portland cement, I part lime paste, and 6 parts sand, or of 1 part masonry cement and 3 parts sand. Add sand so that it is distributed uniformly through out the mass. Then add water gradually until the mortar is plastic enough for use. |
