"Poor man's concrete" is an informal term used in construction and landscaping to describe lean concrete, soil-cement mixtures, or low-cost fill materials engineered with a minimal amount of cement binder. Unlike standard high-strength concrete mixes designed to bear heavy structural loads, poor man's concrete is intentionally formulated with a high ratio of cheap aggregate, sand, or native dirt to save money on expensive cement powder. It is frequently employed for non-load-bearing applications such as stabilizing soft sub-grade soil, filling utility trenches, creating a clean working base layer under foundation footings, or anchoring non-structural posts where maximum compressive strength is unnecessary.
