on-site hydration concrete complex having edge-dropping prevention of cement mixed powder and its on-site hydration concrete mat

摘要

The present invention relates to an aggregate for on-site hydration concrete and a mat for on-site hydration concrete having a function of preventing the edge of cement mixed powder from flowing down. Specifically, a concrete loss prevention unit for preventing the loss of concrete filled at both ends in the width direction The present invention relates to an aggregate for on-site hydration concrete having a function of preventing the flow-down of the edges of the formed cement mixed powder and a mat for the on-site hydration concrete. The present invention relates to a densely knitted first layer and a looser knitted upper part. An aggregate for in-situ hydration concrete consisting of a second layer and a connecting fiber extending across the space between the first layer of the lower part and the second layer of the upper part, in both the width direction of the first layer of the lower part and the second layer of the upper part It is characterized in that it includes a loss prevention part formed by densely planting fiber piles that prevent the loss of cement filled in the interstitial space that is sewn to connect the first and second layers at the ends.
