Abstract

The invention relates to anti-corrosion high-strength coastal building cement and a preparation method thereof. The anti-corrosion high-strength coastal building cement comprises the following materials in parts by weight: 30-40 parts of sulfate aluminum cement clinker, 5-10 parts of ganister sand, 5-10 parts of gypsum, 20-30 parts of quartz sand, 0.1-0.5 part of silicon nitride, 10-20 parts of titanium bearing slag, 1-3 parts of water reducer and 1-3 parts of compound early strong preservative. The coastal building cement provided by the invention has the excellent performance of high strength, compactness, and resistance to permeability, marine corrosion and marine water flushing, and is particularly applicable to underground, port and wharf projects and the other projects corroded by corrosion mediums such as sulfate.

Description

technical field [0001] The invention relates to a corrosion-resistant high-strength coastal building cement and a preparation method thereof, belonging to the field of building materials. Background technique [0002] Most of the main structures of coastal water conservancy projects are concrete structures. And judging from the current development situation, in the next few decades, the materials used in the construction of coastal water conservancy projects will still be dominated by concrete structures. As we all know, once a durability problem occurs in a concrete project, it is very difficult to repair it. Therefore, the coastal water conservancy project should pay great attention to the durability design. For a long time, many coastal water conservancy projects mainly use ordinary cement, and the corresponding seawater erosion-resistant concrete is mixed on site according to the requirements. However, due to the on-site mixing process and quality control problems, it i...
