M350 concrete

M350 concrete is considered elite. It is used where it implies the presence of large loads. After hardening, the concrete becomes resistant to physical stress. It has very good performance, especially in terms of compressive strength.

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

Sand can be of different grains. Crushed stone can be either gravel or granite.

• For the preparation of concrete M 350 using cement brand M400 10 kg. cement accounts for 15 kg. sand and 31 kg. rubble
• When using cement of the M500 brand on 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 of the M400 brand on 10 l. cement accounts for 14 liters. sand and 28 liters. rubble
• When using cement brand M500 10 l. cement accounts for 19 liters. sand and 36 liters. rubble

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

Plasticizers are added to concrete M350 to harden faster. Because of this, it is very important to do work quickly. When laying experts prefer to use immersion vibrators. The structure should not be exposed to direct sunlight. Within a month after pouring, it is important to maintain an optimum level of humidity.

• In the manufacture of plates that must withstand a large load. For example, for roads or airfields.
• Creation of reinforced concrete structures.
• The manufacture of columns for mounting in the design with a significant weight.
• For the filling of the monolithic base on large objects.
