Loess composition for constructional material is provided to emit a lot of UV far-infrared ray and have excellent compression strength and reduced weight, thereby improving constructional workability, by comprising loess as a major ingredient and additives including foaming agent, solidifying agent, feldspar, expandable mica based clay and reinforcing aid. The loess composition comprises: 100wt. parts of loess; 3-5wt. parts of at least one foaming agent selected from silicon carbide, sodium hydrogen carbonate, alumina powder, zinc powder and iron powder or animal protein foaming agent; 2-10wt. parts of polymer aggregation solidifying agent containing polyacrylamide polymer aggregating agent and clay in a ratio by weight of 50:50 to 5:95 or clay solidifying agent; 10-30wt. parts of feldspar; 5-30wt. parts of expandable mica based clay with water content of 0.001 to 1wt.%; 5-15wt. parts of resin based reinforcing aid or glass fiber; and 30-200wt. parts of water.
