CONCRETE COMPOSITION FOR PLAIN CONCRETE USING DREDGED SOIL

摘要

PURPOSE: A concrete composition for plain concrete using dredged soil is provided to remarkably reduce the usage of cement and aggregate by adding an admixture including natural ingredients, and dredged soil instead of aggregate. CONSTITUTION: A concrete composition for plain concrete contains 10~15 parts by weight of cement, 60~70 parts by weight of dredge soil, and an admixture including 20~30 part by weight of a natural ingredient including an agar extract, a grateloupia elliptica holmes extract, and a waterproofing emulsion with sodium silicate component. The admixture is consisted with 10 parts by weight of agar extract, 87~88 parts by weight of grateloupia elliptica holmes extract, and 2~3 parts by weight of waterproofing emulsion with sodium silicate component.
