M350 concrete

M350 concrete is considered elite. It is used where heavy loads are expected. After hardening, the concrete becomes resistant to physical stress. It has very good characteristics, especially in terms of compressive strength.

For production, they use cement, crushed stone, water, sand, and special additives.

The sand can be of different grain sizes. Crushed stone can be both gravel and granite.

• For the preparation of concrete M 350 using cement grade M400 per 10 kg. cement accounts for 15 kg. sand and 31 kg. rubble.
• When using cement of the M500 brand for 10 kg. cement accounts for 19 kg. sand and 36 kg. rubble.

If it is more convenient to use the volume, then:

• When using cement grade M400 per 10 liters. cement accounts for 14 liters. sand and 28 liters. rubble.
• When using cement of the M500 brand for 10 liters. cement accounts for 19 liters. sand and 36 liters. rubble.

• Belongs to class B25;
• Mobility - from P2 to P4.
• Frost resistance - F200.
• Water resistance - W8.
• Increased resistance to moisture.
• The maximum pressure is 8 kgf / cm2.
• Weight of 1 m3 - about 2.4 tons.

Plasticizers are added to concrete M350 so that it hardens faster. Because of this, it is very important to get the job done quickly. When laying, experts prefer to use deep vibrators. The structure should not be exposed to direct sunlight. It is important to maintain the optimum moisture level for a month after pouring.

• In the manufacture of slabs that have to withstand heavy loads. For example, for roads or airfields.
• Creation of reinforced concrete structures.
• Manufacturing of columns for mounting in a structure with significant weight.
• For pouring a monolithic foundation on large objects.
