Hello, everyone.
This is Enta.
With these strong winds, it's a real pollen nightmare, lol.
This is the best time to wear goggles and a mask, lol
By the way, there’s quite a bit of waste during the spraying process, isn’t there?
Do you know what that is?
Even though it was a mortar that didn’t cause any loss when applied with a spray machine,
By the time the materials arrived at the site through the hose, they were completely wasted!!
As the material traveled through the hose along with the air, some of the moisture in the mortar dried out, and
The mortar will end up dry and crumbly.
This results in loss due to material bouncing back from the natural ground during spraying.
Since the residue does not harden any further and lacks strength, it must be removed.
For this reason, we perform frequent air cleaning during the spraying process.
It wouldn't be good to have weak spots in otherwise strong mortar, after all.
There are several ways to minimize this loss, but
To get to the heart of the matter,
1. Change the sand lol
This is the best.
Ultimately, there are significant differences depending on the type of sand.
Any craftsman would understand this, right?
There are quite a few differences depending on the region, after all.
2. Use a little more water.
I completely understand when people say, “That won’t work because we have to measure the surface moisture content, right?!” but,
Adding a little more water helps quite a bit.
It costs a little, but,
3. Add the admixture.
This is also quite effective.
Surprisingly, just installing LeoBuild makes a difference, lol.
The first mix is a bit of a challenge, though.
4. Shorten the spray distance (by reducing the number of hoses).
This is another surefire hit.
After all, the shorter the distance, the less separation there is.
Well, on-site, it’s just part of everyday life that the craftsmen come up with all sorts of ways to make the work possible, so,
The director doesn't think much of it, but there's a certain level of experience that comes with a craftsman's skill that can't be measured by numbers, right?
It really takes a skilled craftsman to install it in a way that minimizes waste.
See you later.
