R - means reinforced.

in the USA it is known as Autoclaved aerated concrete, AAC...

This is cellular concrete. The density in a dry state is 600-800 kg / cubic meter. i.e. it does not sink in water. Thermal conductivity is like that of a wooden beam. It is made in large forms, then sawn into the required dimensions. It is made from sand and cement. Make a very liquid solution...

Perhaps you mean spray insulation or expanding foam. I do not use them. This is a special foam adhesive for cellular blocks, this adhesive does not have secondary expansion, it is for thin-joint block laying. I took a macro photo, the seam thickness is tenths of a millimeter. It is impossible to...

The seam between the blocks is very thin, about a millimeter, the seams will be plastered later, I have never heard about insects in masonry seams.

I lay the second row of blocks, not on cement mortar, but on polyurethane foam adhesive. The blocks are easily cut with a saw with carbide teeth.

Have you checked the oil in the differential, transfer case and transmission, looking for metal shavings?

Is this observed in OD mode only? Does the grinding noise disappear when switching from 4th to 3rd gear? In D mode, after acceleration, release the pedal - is there a grinding noise?

With monolithic concrete, this is how reinforcement is made - and then. concrete. Here, the finished masonry of cellular concrete blocks is reinforced. Without armored belts, lower and upper, it can crack, Therefore, according to the technology of laying walls from cellular blocks, it is...

I walled up the reinforcement in the armored belt, 3/8 seemed thin to me, I used 1/2 steel reinforcement. Ffirst filling the groove with concrete mortar, then sinking the reinforcement into it.

Milled channels for the reinforced concrete belt. Concrete will be poured into the channels and 3/8 reinforcement will be laid. The reinforcement will be in the first low row and in the last top row.

Floods occur every 10-15 years. The water rose more than 10 feet

The garden is located near the river Chulman, literally 30 steps away. Along the river is the best quality soil, the tallest trees and the densest vegetation.

It's all simple there, you can handle it. The eyes are afraid, but the hands do it.

To assemble the electronic part of the stand, you will need a 12V battery. A 5V voltage stabilizer microcircuit of the 7805 type, a 10kOhm resistor, FSD with a radiator and a wiring harness, several pieces of wire, a soldering iron, and insulating cambric tubes. Optionally - a multimeter, an...

Plowed up an abandoned vegetable garden for potatoes.

Pump cam sensor signal - this signal will control the FSD on the bench. Fig. 1 These are the pump contacts.

The pump has two built-in optical sensors, low resolution and high resolution. No external sensors need to be connected. The one built into the pump is used. An open collector is a type of electrical output where the presence of a signal is a low voltage, and the absence of a signal is a high...

To open the FSD, I used a signal from a low-resolution optical sensor. The sensor output is of the open collector type, it needs to be pulled up through a 10kOhm resistor to +5 V.
