Embodiment Construction

[0019] The anti-corrosion and anti-cracking mortar for ocean engineering provided by the present invention comprises the following raw material components in the mass percentage relationship: 20-40% of ordinary Portland cement; 5-10% of fly ash; 5-15% of slag powder; 20% of sand -40%; early strength agent 1-3%; water 10-20%; superabsorbent resin 1-5%; rust inhibitor 1-4%; water reducing agent 1-3%.

[0020] In the present invention, the grade of the ordinary Portland cement is 42.5 grade or above, and the chloride ion content is ≤0.1%. The CaO content in the fly ash is more than 10%, the fineness is ≤ secondary ash, and the chloride ion content is ≤ 0.1%. The slag powder is granulated blast furnace slag powder, the activity index is greater than or equal to S95 grade ash, and the chloride ion content is less than or equal to 0.1%. The sand is any one of river sand, sea sand and machine-made sand, 1.5≤fineness modulus≤3.0, and chloride ion content≤0.1%. The early strengthenin...

Abstract

The invention relates to the field of ocean engineering construction, and aims to provide an ocean engineering anticorrosion and anti-cracking mortar, and a preparation method and a use method thereof. The mortar comprises, by mass, 20-40% of ordinary Portland cement, 5-10% of fly ash, 5-15% of slag powder, 20-40% of sands, 1-3% of an early strength agent, 10-20% of water, 1-5% of super absorbentresin, 1-4% of a corrosion inhibitor and 1-3% of a water reducing agent. Conventional materials and processes are selected, so the cost is low, and the mortar is suitable for large-scale engineering application. The super absorbent resin and the corrosion inhibitor are matched with a reasonable cementing material, so that early self-shrinkage of a cement-based material is obviously reduced, and the comprehensive durability of the mortar is improved. The mortar can easily protect the surface layer of the coastal engineering concrete material and avoid the influences of the addition of the superabsorbent resin on a concrete matrix.

Description

technical field [0001] The invention relates to an ocean engineering anti-rust and anti-crack mortar, which belongs to the field of ocean engineering construction. Background technique [0002] With the rapid development of marine economy, large-scale marine engineering has a huge demand for engineering materials. However, the marine environment is complex and changeable, and marine engineering often has to withstand the comprehensive effects of typhoons, waves, tides, ocean currents, sediments, etc., and also suffers from the synergistic effect of corrosive ions in seawater. The ocean atmosphere is extremely corrosive, and even within tens of kilometers offshore, engineering structures will be affected by salt spray to varying degrees. These environmental and working conditions will have a serious impact on the reliability and durability of marine engineering structures and offshore infrastructure projects, as well as industrial and civil buildings. In order to improve th...
