Why do all concrete slabs need rebar?
When the slab is loaded and force applied to it, the top of the slab directly under the load will be put in compression. However at the bottom of the slab. the concrete will pull itself in tension. Put the ends of your fingers together than flex your wrist up. You will feel the pressure at the top of your fingertips and you will see a gap open at the bottom. That is what is happening in a slab. Concrete is strong in compression, poor in tension. Rebar, or steel, is the opposite. By combining the two, you develop a product that is superior and complimentary to the strengths and weaknesses of the individual materials.

What is General formula for calculating compressive strength of concrete?
Load divided by area of load applied (Load per unit area)
How do you determine if my wall is load bearing for my condo with a concrete flat roof I live in an older two story condo which I live on the second floor and I want to open up a wall?
If the concrete roof is on a brick load bearing wall you cannot open up the wall unless you have a concrete-steel beam below it . If you want a small door or window as opening you can open up the wall (not completely) but lay a beam under the wall for strength .
What is modular ratio of concrete?
The modular ratio of concrete is a measure used in structural engineering to relate the elastic moduli of concrete to that of reinforcing steel. It is defined as the ratio of the modulus of elasticity of steel to the modulus of elasticity of concrete. This ratio helps engineers determine how much the two materials will deform under load and is crucial for analyzing the behavior of reinforced concrete structures. Typically, the modular ratio for concrete is around 8 to 12, depending on the specific types of concrete and steel used.
How much concrete does a concrete truck carry?
some concrete trucks can carry up to 12yards of ready mix concrete. But most times they keep it under 10 yards per load.
Why although concrete components are elastic concrete is inelastic?
Well this is not quite true. Aggregate is a key component of concrete and is inelastic. In addition concrete pillars and beams will bend slightly under load and is thus not 100% inelastic. Polymer modified concrete and rebar modified concrete is also slightly elastic.

What is noun of the load?
The noun form 'the load' is a singular, common noun; load is both a concrete (a load of bricks) or an abstract (a load of guilt) noun, depending on use. The word load is also a verb (load, loads, loading, loaded).

What is the creep of concrete?
Creep of concrete refers to the long-term, gradual deformation of concrete under sustained load over time. This phenomenon occurs due to the viscoelastic nature of concrete, where it continues to deform even after the initial loading, especially under high humidity and temperature conditions. Creep can lead to structural issues if not properly accounted for in design, as it can affect deflections and stress distributions in concrete structures. Understanding creep is essential for ensuring the durability and performance of concrete in construction.
What is creep in concrete?
Creep is what happens when concrete changes form because of pressure or load on the concrete. It can occur immediately or long term.
What would cause clacking sound when car is in gear under load this is a new motor and sound appears to be at the flex plate area?
check your flexplate for small cracks from the bolt holes too the center of it
