Concrete is very strong when under compression (pushed) but when when pulled, concrete is quite weak, sometimes only 10-15% as strong as when compressed.
Reinforcement such as a steel bars is used in concrete to improve its strength. Additionally, concrete structures are often pre-stressed into compression by placing long bolts or rods under tension to squeeze the concrete so that it is still compressed even under load.

Is everything pushed or are objects also pulled?

How are the pushed together and pulled apart?
Both continental and oceanic plates float on the top surface of the mantle, which is divided into convection cells. The movement of these convection cells drag the plates along: where convection causes the mantle material to fall the plates are pushed together and where convection causes the mantle material to rise the plates are pulled apart.
How is momentum determined?
momentum is determined by the force that the object is pulled or pushed by or it can be determined by the position it's in. ex: when a cart is pushed down a hill when you're on roller skates and you're on the part of the hill that is like 5" away from top

What happens to the motion of an object if two unequal forces act on it in opposite directions?
Under these circumstances, the object will be pulled/pushed in the direction the stronger force is acting. (The stronger force overcomes the weaker one.)
