• Mechanical

What type of foundation is shown?

• Pier and Beam

• Basement

• Slab-on-grade

• Piles

Unreinforced concrete is very strong in resisting------------

• Compression

• Tension

• Shear

• Both compression and tension

Rebars are added to the concrete to resist-----

• Tension only

• Compression only

• Shear only

• All of the above and specifically tension

In post-tensioned concrete slabs, when the steel is tensioned, the concrete slab becomes subjected to -------

• Compression

• Tension

• Shear

• None

This plastic is used to ---------

• Keep the water in the concrete slab for curing

• prevent water from moving from the foundation to the soil

• prevent water from moving from the soil to the foundation

• Keep the water in the concrete slab for curing & prevent water from moving from the soil to the foundation

What type of foundation is this?

• Post-tensioned slab-on-grade

• Steel reinforced slab-on-grade

• Hard to say

• Stem wall foundation

The most common type of foundation used in Texas and Southern states is ------

• Crawl space

• Slab-on-grade

• Basement

• Pier and beam

True or False:
