Pouring concrete in columns and walls needs great caution to ensure the achievement of designated strength and durability.
Pour concrete wall definition.
As a material concrete is usually divided into concrete blocks and poured concrete walls.
Poured in place concrete or sometimes called cast in place concrete is a type of building material that is poured into forms where it will set be finished and remain almost permanently.
They are generally economical up to 10 feet in height for cast concrete structures.
Gravity poured concrete retaining walls.
A abrams law the rule of concrete stating that with given materials curing and testing conditions concrete strength is inversely related to the ratio of water to cement low water to cement ratios produce higher concrete strengths accelerator chemical substance added to a concrete mix that reduces the set time by increasing the rate of hydration.
Follow the instructions on the bag of cement and mix accordingly.
If the wall exceeds four feet in height footings should be poured separately.

Pour footings and wall.
Once you have mixed the cement in the cement mixer dump it into the wheelbarrow.
Concrete is a substance used for building which is made by mixing together cement sand.
Roll the wheelbarrow of cement over to your wooden forms and pour the cement into the footing and form area.
Create contraction joints every 4 6 feet.
Pour the retaining wall.
The hollow block wall is depending solely on the strength of the thin mortar bed between each concrete block.
The poured concrete wall has more mass or interlocking cement paste crystals to resist the cracking force.
Counterfort retaining walls are more economical than cantilever walls for heights above 25 ft.
Several factors determine the cost of a poured concrete wall such as the dimensions of the wall the thickness its height and its length the number of reinforcements present and the quality and type of concrete used.
See below for more information on contraction joints remove forms and install waterproofing and drainage system.
The addition of reinforcing steel to either wall system complicates the issue.
Place the concrete in layers and compact each layer properly to obtain a consolidated concrete mass that encircles steel bars and has low permeability.
Gravity retaining walls depend on their own weight and any soil resting on the concrete in resisting lateral earth forces.
Allow concrete to cure.
