Mechanical properties of soilcrete mixtures modified with metakaolin

The present article discusses the synthesis of soilcrete mixes with the addition of metakaolin as a mineral admixture for their potential utilization in civil engineering, either as grouts in soil applications (especially in corrosive environments such as coastal regions) or as a material that can be used for the construction of structural elements (i.e. piles). Soilcrete mix design optimization and mechanical behaviour of the produced samples have been experimentally investigated. It has been found that the beneficial properties of metakaolin may be used in producing soilcrete mixes with improved mechanical properties, which, provisionally, can be used as a structural material.
