Expanding grout

Expanding grout


RW Expand Grout Expansion grout is added to concrete with the aim of creating controllable expansion and the possibility of better connection with the surrounding space. And complies with the following standards:

ASTM C940-989 / ASTM C 845_04 / ASTM C 806


Manufacture of consumer mortars in steel structures of buildings and heavy machinery
Performing injection operations in dams and tunnels
Carrying out repair and repair operations of concrete structures that must prevent the shrinkage of concrete or mortar

Consumption benefits:

Controllable expansion path in concrete
Prevent concrete from shrinking and cracking
Prevent concrete from leaking
Accelerate the time of obtaining initial and final resistances
Compatibility with all types of Portland cements except Type 5
Increase the compressive strength of concrete
Free of iron particles and rust stains

Consumption rate:

Depending on the amount of expansion required and taking into account the amount of C3S and C3A in the cement and the air temperature, the consumption for the mortar is between 2% to 8% of the weight of the cement.

Note: To make low-expansion mortars, it is necessary to perform workshop tests.

Method of Use:

Expansion group should be added to concrete or mortar after complete mixing of all components. (The time required to mix with concrete is about 3 to 5 minutes)

The prepared mortar or concrete should be used for 15 to 20 minutes.

Careful maintenance and processing of executed concrete is mandatory.
