Defects of sea sand in the construction engineering application

Sea sand with low volume, good shape, fineness, sea sand is divided into two kinds of beach sand and sea sand. Beach sand is relatively thin, mostly belong to the fine sand category, while the sea sand is mostly sand, but different regions of the sea sand grading and other differences. However, the sea sand contains high chloride, shell, light substances and other harmful substances, therefore, untreated sea sand easily lead to premature corrosion of concrete in the reinforcement, laying a serious quality problems for the construction.

After the sea sand has been effectively purified, if the chloride ion content and other technical indicators meet the standard requirements, can replace the river sand production of structural concrete, concrete and all the technical performance are good. Sea sand purification technology is the use of fresh water rinse, but the use of fresh water rinse technology to purify the sea water prevalence of large water consumption, high energy consumption, wide coverage of the problem, therefore, the use of mechanism of sand instead of sea sand and river sand is in line with the right strategy for environmental protection.
