It shows that the shrinkage caused by the large content of cement can reduce by partial filling prewetting haydite in the high-strength and lightweight aggregate concrete.
Based on field measurements and experimental analyses of underwater shrinkage cracks, we discuss formation processes of the cracks, sedimentary models of their filling, factors that influence them.
The grouting material have great fluidity, no shrinkage, early strength, gravity flow, excellent filling performance and so on… Simple construction Operation and easy accession to technology.
