In construction terminology, "poor man's concrete" typically refers to a low-cost, low-strength cementitious mixture or backfill material known as lean concrete, soil-cement, or mud-slab mix. It is created by using a significantly lower proportion of cement powder mixed with sand, native dirt, or unwashed gravel compared to standard structural concrete mix designs. This budget-friendly alternative is widely used for non-structural applications where high compressive strength is unnecessary, such as creating a temporary sub-base under foundation footings, filling vacant trenches, stabilizing loose soil before pouring a proper slab, or setting fence posts where maximum load-bearing capacity is not required.
