材齢初期において低温養生をおこなった高曲げ強度セメントモルタルに関する研究

抄録

In this study we investigated the high bending strength cement mortar. Generally, cement mortar has low bending strength although it has high compressive strength. This problem is very important for cement mortar and concrete. Therefore we attempted to study about high bending strength cement mortar. As the technique, we aimed at curing the high bending strength cement mortar under the low temperature in early age. As the result, the effect of curing under the low temperature for 3 days from placing was found as the method for increasing bending strength of cement mortar, decreasing shrinkage and decreasing pore volume.
