when the concrete whose load weight limit is 100 kg in one square meter, it is considered a low strength concrete

# data[].attributes.body
These concretes are used in false floors, false footings, slabs,
or in places where they do not have function

is important as it determines the degree settlement of the concrete, which will depend on the type of construction.

here it is possible to appreciate that they are using the 210 resistance concrete

The ACI (American Concrete Institute) tells us that high strength concrete is one that has a compressive strength, f´c= 450kg/cm2

# data[].attributes.body
The water cement ratio for the concrete of f´c= 450 kg/cm2 is 0.38 without air entrained.

# data[].attributes.body
210kg/cm² concrete is very workable and can be used in beams, footings, slabs, stairs and walls

High-rise structures or structures subject to significant stress.

In all structures where it is required to obtain high resistance at 28 days or there is an interest in reducing the sections.

In wide-span bridge superstructures and where it is required to improve the durability of the elements.

Where low water/cement ratios are needed (storage tanks, dock structures, structures in contact with sewage, etc.)

* 0.1415 m³ of sand
* 0.1415 m³ of gravel
* 1-1/2 cement sleeve
* 2 buckets of water of 5 gl

# data[].attributes.body
For one cubic meter, 5 bags of cement, 12.5 cans of water, 35 cans of sand, 40 cans of gravel are needed.

# data[].attributes.body
The resistance obtained offers the possibility of smaller sections and therefore a lower weight of the structure.

Its dense and slightly porous matrix makes it low permeability to gases and liquids.

They protect the reinforcing steel, increasing the durability of the structure.

It has high fluidity that makes it possible to place it even in areas with a high density of reinforcing steel, allowing greater performance in the execution of works.

Greater resistance to hydraulic abrasion and impact.
