Abstract

The invention discloses a production method of wind-resistant and wave-resistant cement mortar for an offshore engineering. The wind-resistant and wave-resistant cement mortar for the offshore engineering comprises the raw materials: machine-made limestone sand, rapid hardening sulphoaluminate cement, superfine silicon powder, a composite coupling agent, a dispersible latex powder, cellulose ether, starch ether, a water reducing agent and slag powder. The wind-resistant and wave-resistant cement mortar for the offshore engineering, disclosed by the invention has low alkalinity, acid and alkaliresistance, early strength and rapid hardening and is sustainably improved in later strength, beneficial to the improvement of safety and durability of reinforced concrete, high in wind and wave resistance and suitable for offshore engineering construction such as ports, seawalls, coastal protection, cross-sea bridges and offshore filling stations.

Description

technical field [0001] The invention relates to the technical field of building materials, in particular to a production method of marine cement anti-storm mortar. Background technique [0002] Since the second half of the 20th century, the world's population and economy have expanded rapidly, and the demand for protein and energy has also increased sharply. With the exploitation of oil and natural gas in the continental shelf sea area, as well as the continuous expansion of marine resource development and space utilization, it adapts to it. China's offshore engineering has become one of the fastest-growing projects in the past 30 years. [0003] Due to the continuous erosion of seawater, seawater rich in chloride ions and sulfates can easily corrode the marine projects constructed with marine cement. According to the particularity of marine cement technical indicators, it mainly lies in the requirements for chloride ion diffusion coefficient and sulfate erosion resistance ...
