Abstract

The invention discloses seawater-resistant cement, and belongs to the technical field of building materials. The cement comprises the following constituents in parts by weight: 10-15 parts of cement clinker, 2-6 parts of coal ash, 2-4 parts of zinc oxide, 10-20 parts of magnesium oxide, 5-8 parts of aluminum oxide, 5-8 parts of volcanic rock fibers, 10-15 parts of silica and 0.8-1.7 parts of ammonium nitrite. The cement is good in weather resistance, adhesion and oxidation resistance, and can effectively resist chemical corrosion and microbiological corrosion in seawater, as well as seawater erosion and temperature difference caused by climate change.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to seawater-resistant cement. Background technique [0002] The conditions of high salinity and numerous microorganisms in the marine environment put forward higher requirements for underwater construction materials. At present, ordinary Portland cement and a small amount of sulfate-resistant cement are mainly used in ports, docks, and marine engineering in my country. This type of cement has poor impermeability, wear resistance, and compactness. Therefore, seawater erosion resistance, seawater erosion resistance and freeze-thaw resistance cannot fully meet the technical requirements of marine engineering, resulting in poor engineering quality and short service life, which has brought greater losses to national economic construction. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a seawater-resistant cement,...
