School of Civil Engineering，Shenyang Jianzhu University，Shenyang110168，China; aqianqian45220@126.com Keywords: Retarder; Grouting material; Ultra strength; Final setting time Abstract: To explore retarders on performance of ultra-early strength grouting material, Retarder, which are commonly used in the market after a preliminary screening, are further tested and analyzed for initial fluidity, setting time and mechanical strength properties of super early strength grouting material.
In practical engineering application process, the improper use of retarder, or the suited between admixture, result in abnormal condensation of grouting material.

Determination of the apparent activation energy of concrete by adiabatic test Wang Jiachun 1, a 1 Department of Civil Engineering, Xiamen university of technology, Xiamen, 361024, China ajchwang@xmut.edu.cn Keywords: Concrete, Apparent activation energy, early age, adiabatic test .
For engineering application, the ratio between the liberated heat of hydration Q (t) at time t and the total liberated heat at complete hydration Qmax is considered the most convenient index to express the hydration degree Where is liberated heat at time t, kJ kg-1 is total liberated heat of complete hydration, kJ kg-1 The heat liberated at time t can be determined from continuous measurements of the adiabatic temperature rise, measured during tests performed by adiabatic calorimeter is adiabatic temperature rise, ℃ is specific heat of concrete, kJ kg-1℃-1 The maximum amount of heat Qmax liberated at complete hydration can be directly determined from the clinker composition of the cement.
