Title:
沿岸異形構造の３Ｄ印刷コンクリート、加工プロセス及び応用
Document Type and Number:
Japanese Patent JP7362083
Kind Code:
B2
Abstract:
A coastal special-shaped structure 3D printing concrete, a processing technology and the use thereof. The raw materials thereof are compounded cement, regenerated sand, fly ash, polyvinyl alcohol, graphene oxide, steel fibers, organic fibers, a water reducing agent, a thickening time control agent, a mineral admixture and water. The 3D printing concrete has a good cohesive water retention and adjacent thin layer interface cohesiveness. The formation of a micro-capacitor by combining GO with a PVA electrolyte avoids the formation of a corrosion cell in a thin layer of concrete, and the concrete has a good marine durability.
