What are concrete pouring mean? To place a fresh concrete from truck or mixer using a various method to the structural element like slab,beam and so ever.
First of all that is a tradisional method using a wheel barrow or dumper truck or bobcat now collect a fresh concrete from mixer to the place of concrete and by using a scop to fill the concrete to the footing,beam and so on
This type of pouring are suitable for small project whereby ingnore about quality.Ftom mixed of concrete until pouring of concrete too difficult to control the quality.To control the mixed procedure using a box snd then tranfer it to the placing take a long time to finish the job at the day and also the workers not a robot can doing a job at same quality and msybe morning can get grade 25 of concrete but afternoon the grade down to grade 15.
This type of pouring still usef for small project not a structure one like base og fence pole,fence beam and a small building like a huts and project not concern about quality.
The second method poured used a crane with bucket.The fresh concrete from the ready mix truck pour to the bucket and using a crane to transfer the fresh concrete to the place.This the faster way right now.'But this mehod have a limit depending on the height of the building and distance from between the structure and the truck or mixer.The mobile crane also have a size between 20 T and 40 T depending on the height of the building.
Right now tall crane are used for high building to transfer and pour the fresh concrete.The bucket also have a size from 1/2 mcu to 1 meter cube.Its depend how big the structure.Normally a site ready mix or imported ready ready are used and this type of pouring more faster snd cheaper and also the quality is there.
The third method of pouring is using a pipe boom and concrete pump to transfer and pouring if the fresh concrete.Normally fresh concrete from the truck pour to the concrete pump and pumping through the pipe until to the structure.This type of pouring suitable for condition that trucks cant go near to structure may be no road or have an obtruction like many building before and then far the way from the truck place.
Author have an experience supervised pouring concrete using a boom with concrete pump.Concreting for spill way structure at Batu Dam whick trucks cant go near the structure coz the terrain condition.The most important thing to make sure that the mixed not to dry and can stuck inside the pipe.The stuck concrete can make a concrete pump jamned.To released have to detect which point stucked and dismantle the pipe and then pump the stuck concrete out before continuing concreting and this type of pouring maybe costly and not suitable for small project.
Pouring have a quality aspect to control it are the height of pouring to the element.To avoid segigration the height between the start point of pour to the final point of pour not more than 4 feet.The second is the pattern of pour like a slab pour that the pouring system must easy to vibrate that not too thick and not too thin to avoid honeycom.
