Matters Needing Attention on Marine Sand Making Plant
In normal building sand, there usually mixed with some shells. People who have certain knowledge on sand making plant would recognize that these sand should be made from marine sand production line. China has broad coastline, so the yield of marine sand is very large and it has used in various construction.
But the thing need to be noted is that although as a kind of natural sand, marine sand cannot be compared with river sand. that is mainly because the two kinds of sand’s forming environment are completely different. Sea sand is formed through ocean tides and corrosion of sea water, so there are a lot of chloride ion in sea sand, but excessive amounts of chloride ions may cause corrosion to steel structure and reduce the service life of building. Some cracks, collapse phenomenons of houses have happened in the coastal area in China.
Therefore, we should clear know the mechanism sand and natural sand when choose sand,and whether it is river sand or sea sand. When choose sea sand used in construction, we should choose the sea sand which is produced by large manufacturers because they adopt new equipment for the production of high quality and sea sand of dechlorination process, thus can ensure the safety of construction and houses . We can buy the sea sand which pass safety inspection and this kind of sand can meet basic demands for building.
