One will be poured concrete while the other one will be standard 8 inch hollow core block.
Concrete walls poured in lifts.
The one force is a downward force gravity load created by the load placed upon the wall.
There are two forces which act primarily upon foundation walls.
Pouring of concrete in columns and walls if the height of these elements is large then it is recommended to place concrete in layers.
They are typically used for larger structures with higher dead loads.
It is constructed as a load bearing structure to transfers loads from floor to the wall below or to the foundation in addition to divide spaces in multi storey buildings.
In this project 40 foot concrete walls were poured using formwork rated at 1650 psf.
This is done in multiple lifts of around 4 feet or less.
A grout pour is the total height of masonry to be grouted before additional masonry is installed.
However let s compare two 8 inch thick walls.

Pouring concrete walls in lifts.
Moreover concrete wall is a desirable structural element in earthquake prone areas since it exhibit.
Grout lifts greater than 12 inches must be mechanically vibrated twice once at the time of grout placement and a second time after water has been absorbed by the masonry units but before the grout loses.
Another type of common footings are pilings.
Forms are placed in drilled holes steel reinforcement is placed and then concrete is poured in lifts with mechanical vibration to ensure.
In actual practice each wall was completed in a single continuous pour in one day.
The other force is a sideways or lateral force.
In typical residential construction concrete is commonly placed in a wall to a maximum of 10 to 12 feet in height during one concrete pour.
Pilings are used to reach more deeply through unsuitable soil to bearing soil or bedrock.
In commercial construction walls may be higher 14 to 18 feet.
Cast in place concrete also known as poured in place is a concreting technique which is undertaken in situ or in the concrete component s finished position.
Construction of concrete walls is a crucial phase in building construction.
If the full hydrostatic pressure assumption was imposed the lift height would be limited to 11 feet requiring more than three separate concrete placements.
