Effect of Chloride Ion Content and Replacement Ratio of Manufactured Sand on Performance of Sea Sand Masonry Mortar
https://orcid.org/http://orcid.org/0000-0002-5909-9477
Because of the increasing demand for construction and the limited river sand resources in China, using sea sand to prepare sea sand masonry mortar (SSMM) in coastal areas can save river sand resources, but it will have a certain impact on the performance of mortar. Sea sand with different chloride ion (Cl−) content and replacement ratio of manufactured sand were prepared. The effects of hydroxypropyl methyl cellulose ether (HPMC), Cl− content and replacement ratio of manufactured sand on the workability, mechanical properties, cement hydration and pore structure of SSMM were studied. The results show that HPMC can increase the consistency and water retention of SSMM, decrease the 2-h consistency loss rate and prolong the setting time of SSMM. Cl− in sea sand has different effects on the mechanical properties of SSMM. Sea sand partly replaced by manufactured sand has a positive effect on the mechanical properties of SSMM. Cl− has an obvious promoting effect on cement hydration. Cl− in sea sand can optimize the pore size distribution of SSMM, but increase the total porosity, total specific surface area and pore connectivity of SSMM. Sea sand partly replaced by manufactured sand makes the total pore volume of SSMM decrease and optimizes the pore structure of SSMM.
