When steel makes contact with concrete a non reactive film develops on the surface of the rebar that helps protect it from corroding. Strength reduced from 136 7 to 114 9 in kips. Pour the concrete slowly keeping an eye on the steel mesh as you do so to make sure that it doesn t become displaced.

Building a reinforced concrete block wall solid grouting and a hefty rebar schedule turn a unit block wall into a monolithic shear wall. The trick is to insert vertical steel rods from top to bottom in the hollow cores and fill those hollow cores to the top with mortar. For example you can make a concrete block wall stronger than a poured concrete wall by simply adding some reinforcing steel and additional mortar to the block wall. It should take about 24 48 hours for your concrete to dry and set.

Use a metal rake to make sure the concrete is evenly spread throughout the entire forming. The deformations in rebar bond to concrete and the strong bond enables loads to be transferred between the two materials. Reinforced steel is manufactured as bars rebar or welded wire mesh. But unlike plain concrete which can last for centuries reinforced concrete can deteriorate in decades as the reinforcing bars succumb to rust.

Slenderness ratio is equal to least of l t or h t where l is effective length of wall h is effective height of wall t is thickness of wall if 12 the wall is short and if 12 the wall is slender. Arrange the rods in two layers of an equal number such as three rods above three rods beneath.
