Cement-based grout ZG400

The installation & fixing on foundation base plates is the most important and sensitive part in steel structures. Installation of base plate on the foundation should be done without any errors and with taking into account all relevant points and details. After installing the base plates by anchor belts and closing the nut and leveling the base plate surface and ensuring about correct placement of the plates on the screen, the most important job for finishing the installation process is pouring mortar below the base plate. Because of little resistance and shrinkage out of losing water through the gripping process, any usage of ordinary mortars or concretes is not a suitable option in the setting process. Also it may cause settlement of structure due to water loss and shrinkage. To solve this problem, ready-made mortars without shrinkage and capable of construction have been formulated and produced under the name of grout. Cement-based grouts are much more powerful than construction mortars and in addition to having high strength, in terms of their special formulation, they create special properties for installing column bases. Special cement-based grout, rather than having higher strength, it has a good lubricant property. This may facilitate the flow of mortar under the support plates.
 Also, some materials have been used in the formulation of cement grouts that increase the volume of mortar. This special property will compensate the reduction of volume due to hydration of cement and will prevent the mortar from shrinking and contraction after drying. This parameter is very important in installing and fixing the support plates on the foundation. In the composition of cement-based grout, powder lubricants are used, which in addition to creating fluidity in the mortar, due to the water-reducing properties, ultimately make it possible to achieve higher strength. Also, the lubricating property of grout will cause excellent mortar flow to farther points and easier filling of sections with higher reinforcement density without the need for a vibrator. Cement-based grout has a higher efficiency than ordinary mortars for filling sections in paste and has a high resistance against temperature changes.

Packing: 25Kg bags​​​​​​​

Mode: Powder (Gray)​​​​​​​

Properties:

Finding primary resistance without any need to apply gripping accelerating materials
Reducing permeability & absorption of water
Controlling the shrinkage of concrete plastic due to the gas expansion
High resistance against melting & freezing cycles
Quick utilization from construction
Controlled expansion (volume changes)
High resistance against climatic condition
Resistance against high static loads
Lack of tracking after hardening

Consumption method:

Please mix the product with enough water to obtain a harmonized and integrated composition. The important point is not to pour great amount of water, because it may reduce its pressure resistance rate. It is suitable to use 120 -140 gr of water for 1kg of grout powder.

Consumption rate:​​​​​​​

It is possible to specify consumption rate by calculating the section volume and considering the special weight of cement- based grout. But it is generally equal to 2240 kg of grout against one cubic meter of space. One 25kg bag of cement-based group will fill about 13 liter of space.
