The invention discloses novel frost-resistant concrete. Raw materials comprise cement, stones, yellow sands, melon seed-shaped drug slices, coal gangue, phosphorus slag powder, zeolite powder, rubber powder, a carboxylated butadiene-styrene rubber emulsion, cellulose, a water reducer, an accelerator, a compound pumping aid, an alkaline-aggregate reaction inhibitor, sodium thiosulfate, sodium acetate and water. The compound pumping aid is obtained by mixing, grinding, crushing and screening calcium lignosulphonate, a polycarboxylate efficient water reducer, anhydrous sodium sulfate, sodium abietate, hydroxyethylmethylcellulose and coal ash. The novel frost-resistant concrete is high in strength and good in frost-resistance.
