Be constructed in the Middle East, recent overseas plant business mainly due to an increase in the amount of concrete in the construction sector is growing. When using plain concrete and concrete development of the initial expansion of the initial hydration, due to thermal stress that causes cracks in the concrete problems, and prevention of this by the use of the delay is expected to increase. In addition to the increase in domestic traffic produced in ready-mixed concrete plants and concrete due to high temperature during transportation upon arrival at the scene quickly if condensation begins to degrade due to the slump loss and workability after curing of cold joint and cause filling defects and the need for the measures . In the case of the powder that is currently on the market in order to obtain a uniform delay effects can be mixed, may be added, such as, wet, etc. Keep a less efficient storage, even if the delay has to be taken. This powder improves the delay and store it in a tablet, a delay effect to encourage the development of tablet, and the delay for compliance with basic properties was investigated.
