What are Rebar Shakers?
A rebar shaker is a vibratory device attached to steel bars which turns them into a vibratory instrument to consolidate the concrete. It is designed to compact concrete in reinforced concrete elements that cannot be reached easily, such as congested ...
Concrete Revibration: Effects on Concrete and Applications in Building Construction
Concrete revibration is a deliberate and systematic vibration of concrete that has been vibrated sometime before. It can be carried out at any time provided the concrete remains plastic and the vibration instrument penetrates concrete under its weight. However, the ...
Practical Tips for Using Concrete Vibrators in the Field
Vibration is one of the methods used to consolidate poured concrete to achieve required density and, subsequently, the designated concrete strength. Vibrators (internal and external or shutter vibrator) need to be used properly and skillfully; otherwise, the concrete may get ...

The major problems that one encounters when pumping concrete are blockage of pipeline, and segregation and bleeding of concrete mix. Blockage is the failure of concrete to emerge at the end of the pipeline. It is characterized by an increase ...
How to Prevent Honeycomb in Concrete Structures? Video Included
The prevention of honeycomb in concrete structures can save time and money, and help construct structurally sound concrete members. Therefore, undertaking preventive measures to avoid the occurrence of honeycomb is of utmost importance. The measures include proper compaction, use of ...
How to Consolidate Concrete in Congested Reinforced Concrete Members?
Consolidation of fresh concrete in congested concrete members should be performed using proper concrete pouring and compaction procedures. Otherwise, the concrete element suffers from strength deficiency and durability loss due to problems like honeycomb and poor concrete cover in addition ...
Understanding Water Leakage in Concrete Structures: Its Causes and Prevention
Proper understanding of the causes behind water leakage in concrete is necessary for designers and site engineers to incorporate the preventive measures. Several factors, like the use of poor-graded aggregate, overdose of admixtures, deviations from designated mix, improper concrete placement, ...
