Frequently Asked Questions
What is concrete mixing?
Concrete mixing is the process of reducing the amount of trapped air, voids, and air packets in the newly installed cement mix, usually using manual or mechanical mixing methods.
How can you determine the radius of the impact of the internal vibrations using the field view?
Determine the radius of impact on the field by noticing how far away the bubbles from the vibrator's head are to escape the concrete. Alternatively, use a range of 1-1.5 times the radius of influence.
What happens if the poker vibrator is active in the air?
Active poker or indoor vibrator can cause overheating and malfunction of the tool.
Why is it important to maintain the form edge and internal vibration space?
Keep a distance of 7-10 cm between the edge of the formwork and the head of the vibrator to avoid damage to the formwork.
How long should the concrete be moved using internal or external vibrators?
Continue to vibrate until concrete levels form, coarse coarse particles are embedded, a thin film made of mud on top and surface of the formwork, and the appearance of air bubbles on the concrete stops.
What happens when the concrete collapses?
When the concrete stops vibrating, it loses its consistency and suffers from cracking. Aggregates will remain at the bottom of the formwork, and the cement paste will rise to the top of the element. As a result, the strength of the concrete decreases to bees.
