Shashi was a contractor help while I interned with engineer Ashraf. And he was called “Idimutti Shashi”. Of course, you can tell he’s Gunda just by his name. When he heard that Gunda was on the scene, he thought of brushing up his defense method, but he gave up after hearing about his background.
Because Idimutti Shashi is not Gunda as we think. He’s just a mason who doesn’t even know how to level concrete properly. So his Velayudhan, a contractor, regularly assigned him the task of solidifying it after the concrete. As such, Idimutti is the local name for wooden masonry tools used during concrete work. Because he always carries an idimutti on his back, he came to be called an idimuttisasi.
But it’s not the sashi that matters here, it’s the idimutti. We’ve already talked about Idimutti, so let’s find out why the concrete has set so hard. But before we look at that, let’s take a look at the different stages of concrete. But let’s talk about content.
Slab concrete is the process of pouring a concrete mixture specified according to the water-cement ratio onto a centering surface, neatly leveled, routed and covered with cover blocks.
Compression with a vibrator then flattens the mound of concrete, revealing water on top. Soon the masons level it with planks and shovels. Plus he has to wait 20 minutes. In the meantime, another area can be fleshed out. By then, the initially poured concrete will slowly begin to dry. This takes about 20 minutes.
So let’s call Idimutti Sashi. We know his job is to level the concrete. It is technically called concrete tamping.
We’re not done yet.
Hardening concrete does not mean hitting hard. Gently tap from a height of about 4 inches. Only use wooden mallets and not thick iron mallets for some reason. Otherwise things will go wrong. So why do we need to bang like this?
When concrete is placed, small air bubbles may enter inside. Small creatures are trapped inside. These air bubbles and tiny creatures burrow through plain concrete and reach the top.
You need to walk backwards while hitting like this. Do not kick the side that has already been hit. This compaction gives the concrete a special finish. This is called tamping finish. However, when concrete is poured with large pieces of metal, this small tap is not enough. Need a good knock. It’s also a good iron strike. This pouring of ready-mixed concrete is called pounding.
These are the ones that should be underlined here.
1- Do not use steel hammers on slabs or reinforced concrete, hammer very slowly.
2- Concrete floors with large metals should use a steel-like thickness hammer.
3: Idimutti Shashi is not Gunda.
