Abstract: The present invention discloses cement mortar containing excavated soil prepared by replacing natural sand with engineering soil, and a preparation method therefor and an application thereof. The preparation method includes drying and grinding waste engineering soil taken from a construction site first, sieving and mixing it to form recycled engineering soil, and putting the recycled engineering soil and natural sand into a mortar mixer according to a certain proportion to form a sandy soil mixture; then pouring water and cement into the mortar mixer, adding a part of the sandy soil mixture and a part of a water-reducing admixture, and evenly stirring; and finally, adding the remaining sandy soil mixture and water-reducing admixture, and evenly stirring to obtain the cement mortar containing excavated soil.
