What is the reason for punching with Expansive Mortar?

Time:2024-08-05 Browse: 289

The punching phenomenon is caused by improper temperature control of the Expansive Mortar, resulting in a rapid reaction and causing the actual stone to crack. When using rock expansion agents, the following points should be noted:

Drill holes in the rock to be demolished, taking note that using smaller drill bits may reduce the expansion strength.

Mix the expansion agent and water in a certain ratio, usually 1:3 or 1:4.

Pour the mixture into the stone hole and wait.

During use, attention should be paid to safety to prevent punching and eye injuries.

The cracking time is usually 8-24 hours, and do not observe the situation inside the hole with your eyes within 5 hours after injection.
