4 TYPES OF VIBRATORS COMMONLY USED FOR CONCRETE

Aug 03, 2015 · Vibrators are commonly used as a way of compacting concrete on site. In case of vibration, compacting gets effected by reduction in internal friction between various particles of concrete due to oscillation of particles which results in a dense and compact mass of concrete. Vibrations can either be Produced in the interior of the concrete []

Minimizing Concrete Costs

Minimizing Concrete Costs The most expensive ingredient in concrete is the cement, so minimizing concrete costs means minimizing the amount of cement. Is there a practical minimum? Sure! Ideally, each piece of fine or coarse aggregate should be totally surrounded by cement paste and all the voids between aggregate particles should be filled in.
