As the cement grade is not enough or expired cement, water-cement ratio is too large wipe a few times is not enough pressure, premature curing during the operation of other processes, are easy to cause the phenomenon from the sand.

Owing to lack of cement grade or with an expired cement, cement ratio is too large put on pressure again, conservation during early enough for other process operations, are prone to sand streak phenomenon.

Because the cement strength insufficient or the use expired cement, the water ratio oversized wipe prematurely presses the number of times insufficiently, curing period of concrete carry on other working procedure operation, all easy to create the granulated substance phenomenon.

Because the cement marks: not enough or use outdated cement, cement water than too much pressure washer, not enough conservation during times of premature other processes, are easy to create a sand phenomenon.

Owing to lack of cement grade or with an expired cement, cement ratio is too large put on pressure again, conservation during early enough for other process operations, are prone to sand streak phenomenon.
