The invention discloses a concrete foaming agent. The concrete foaming agent is prepared from the following components: sodium dodecyl sulfate, triethanolamine, methyl cellulose, sodium alpha-olefinsulfonate, polyallylamine, propane diacid, modified bentonite and water. According to the invention, through modification of bentonite, foam is allowed to be more uniform and finer, and foam concrete prepared from the concrete foaming agent has higher strength and better heat insulation performance; methyl cellulose and triethanolamine are doped, methyl cellulose can guarantee the foaming rate of the foaming agent, triethanolamine can greatly improve foam stability, and mixed modification of the foaming agent by methyl cellulose and triethanolamine enables the foaming agent to have ideal effect and stability of foaming of the mother liquor of the foaming agent to be improved; and the concrete foaming agent uses widely available raw materials, has low cost, is simple to prepare, and overcomes the problems of poor foamability and foam stabilization performance, high cost, complex preparation technology and the like in the prior art.
