This I see for the first time

In construction, quality of materials - it is a loose concept. And sometimes not clear where the distinction between normal and poor quality.

For all the construction of his house, I came across this, and this is once again brought me a strange sand.

Pit sand - what is this?

As a normal person and a layman in the construction businessI have general theoretical concepts about the kinds of sand.

❗ I know that pit sand - this is the most low-grade material, due to the presence of stones, clay, and maybe some more impurities.

But basically the same it has to be sand?

I also brought the sand with stones in a ratio of perhaps 50 to 50. Accurately measured course not, but the feeling had such. And most likely it was not done on purpose, but I just so "lucky."

There is one question: "What to do about it?" Here the important purpose of using sand. I've had a few:

The cement-sand mortar.

It was his first appointment is not my construction site. The work is complicated only by the fact that it is necessary to sift the sand. For this, I fashioned a sieve.

After sifting the sand gets excellent, and a great bunch of stones. 😁 By the way these stones also can be further applied in landscaping the yard.

Concrete.

There is one very important point, especially for beginners like me.

❗ The concrete composition includes three components - is cement, sand and gravel. And I at first a question: "Why sift through the sand on the stones, which in fact are the rubble?"

But the strength of the concrete is very important this difference. Simply put smooth stonesContained in the sand will have a significantly lower adhesion to the concrete, as compared to rough gravel.

Therefore, for concrete, which I will also need have the same sifting the sand.

Sand bed.

Here it is the perfect place for such an peska.👍

In the process of the construction of walls of the house, I had a short break due No glue for aerated concrete. And to save time, I decided to sleep a pillow under the blind area around the house.

All of the technology. First, the sand, then pouring some water and tamping (as always, my hand tool). After I manually rammed a pillow under the whole foundationThis work seemed to me easier to nowhere.

And most importantly, that with so many stones, this foundation will be even tighter.

✅ So that in the construction, as in life You do not need to complain about something that gets you, and include your head and squeeze all the benefit from the situation.
