Description

technical field [0001] The invention relates to the technical field of marine engineering materials, in particular to a sea-sand interlocking block for a port storage yard and a preparation method thereof. Background technique [0002] Cement concrete interlocking block pavement is a new type of pavement. It was introduced into my country in the mid-1980s. It has the characteristics of strong load-bearing, not easy to deform, and strong anti-skid ability. It has been used in various port and wharf yard projects. a wide range of applications. With the depletion of river sand resources, more and more attention will be paid to the rational use of sea sand resources. my country has a long coastline and a large number of ports. Every year there is a problem of sediment deposition, which directly affects the safe operation of the port. In order to ensure that the waterway is deep enough, a large number of dredging operations are carried out every year. Most of the dredged sea sand...
