Contemporary building are becoming enlargement and high-rise.
Also steal reinforced concrete buildings are increasing. for this reason, the methods of concrete delivery and placement varied and developed. Among those, conveying method using a pump is used commonly because is superior to bucket on hoist for cutting a term of works and economical efficiency. It is able to convey directly to high stories by improved pumping capability and improved concrete quality.
In this research experiment to estimate changing of physical properties about fresh concrete by increasing pressure, increasing. pumping distance. the methods of this experiment are analysis and comparison about. fresh concrete condition. before, and after pressing. throughout this the purpose of this research is furnish basic data of physical properties.
The more concrete was pressured by pressing devise, the more Slump flow was increased. Air content with the pressure increasing was decreased. It is similar to the result of existing research on the pump conveying. So was strength.
