The　development　of　high-performance　aggregate　is　a　key　direction　of　sustainable　concrete.　One　effective　synthetic　technology　for　producing　artificial　aggregates　is　hydrothermal　synthesis.　Using　waste　basalt　mud　from　the　construction　of　a　low-carbon　industrial　park　as　a　raw　material　further　facilitates　the　utilization　of　solid　waste　resources.　Therefore,　this　paper　adopted　the　hydrothermal　synthesis　method　to　produce　artificial　aggregates　developed　from　basalt　mud　(AABM).　Subsequently,　it　was　used　to　partially　replace　mechanical　aggregate　in　the　preparation　of　concrete　with　strength　grad　C30.　The　engineering　properties　of　concrete　prepared　with　AABM　(C-AABM),　including　workability,　densities,　mechanical　properties,　and　frost　resistance,　were　investigated　to　assess　the　feasibility　of　using　AABM　as　concrete　aggregates.　The　results　showed　that　the　fluidity　of　C-AABM　can　be　significantly　improved　by　using　AABM.　The　hardened　C-AABM,　prepared　with　10　∼　30　vol%　AABM　instead　of　mechanized　aggregate,　exhibited　a　dry　density　decrease　of　less　than　5　%,　indicating　the　feasibility　of　using　AABM　for　ordinary　concrete.　However,　excessive　AABM　negatively　affected　the　mechanical　properties　of　the　concrete.　When　the　AABM　substitution　was　no　more　than　15　vol%,　the　impact　of　AABM　on　the　compressive　strength　and　modulus　of　elasticity　of　C-AABM　was　less　than　15　%.　Nevertheless,　the　performance　of　the　concrete　deteriorated　dramatically　with　the　addition　of　AABM　under　freezing　conditions.　As　described,　the　primary　engineering　advantage　of　preparing　C30　concrete　with　AABM　is　to　improve　the　workability　of　the　fresh　matrix　without　significantly　reducing　the　mechanical　properties　of　the　hardened　concrete.　It　proves　the　viability　of　AABM　as　an　alternative　aggregate　for　ordinary　concrete　production.　©　2024　The　Authors
