Research on the Properties of Sea Sand Concrete

With the rapid development of construction, the amount of sand used in construction is increasing, and the river sand resources is difficult to meet the growing demand for river sand. With the awareness of ecological protection in recent years, the country have gradually taken measures to limit the over-exploitation of the river sand. Using sea sand to produce building materials is a general trend, such as sea sand concrete. In this paper, using sea sand and river sand to make concrete, and comparing the performance of them. Studies have shown that, compared with the ordinary concrete, the strength of the sea sand concrete modified by colloidal crystal has improved significantly.
