Self Compacting Concrete Pp

I'm_____________, everybody knows me.

My project's name is "Innovation in construction"
You wonder what is this?
This is a big advance for engineering.
I'll talk about Self Compacting Concrete.Self Compacting concrete (SCC)
(by the acronym in English)
Is a mixture, of materials like sand, gravel, water and additives.

Is characterized by a high yield, high deformability and moderateviscosity necessary to ensure uniform suspension of solid particles during transportation and placement.

Transporting to jobsite and
placement means strained in place and accommodation.

Thisconcrete can be used for reinforce sections in the places where there can be no access to vibrators for compaction and in complex shapes of formwork.

I'll tell some advantages and somedisadvantages to use SCC.
Advantages | Disadvantages |
This is concrete is economic in the use of precast industry | The relatively high cost of material used in this concrete for built only house. |Access to restricted areas | |
Enhances flowability and stability | |

And finally I'll explain five tests necessary for use the SCC.

* The first is slump-flow.

In this picture thetechnicians added the self compacting concrete in the Abrams cone, then they removed the cone and wait the mixture is disperse.
Is permitted that the diameter measured between 650 and 800 millimeters.* The second is V Funnel

This test is to check the flow.
Added the mixture in the v funnel, there is a blockage.
Then you take the blockage and the mixture release.
The mixture should berelease between 6 and 12 minutes.

If it doesn't reach the requirements, it can't be used.

* L box

Here added the mixture again, here is a blockage too.
The mixture be released, but with abarrier of 90 degrees and the SCC goes through the barriers between 20 and 40 centimeters.

* Fill Box

In this test added the mixture in the box, and the concrete must pass between holes or...
