Abstract

The invention relates to a tunnel concrete additive with slushing, high-early strength and impervious three-in-one effects, which comprises the components with following proportioning by weight: 20-30 portions of surfactant, 45-50 portions of excitant and 20-30 portions of water-proofing agent; and comprises 230-400% of carrier. The additive is prepared by homogeneously mixing the surfactant, the excitant and the water-proofing agent according to certain proportioning and then homogeneously mixing with the carrier material (commercial fly ash). The additive is added with energy-conserving environment protection products comprising a great amount of industrial waste from the thermo-eletric plant matched with part of inorganic and organic waste form the chemical plant, which reduce dosage of cement, and can sufficiently exerts gelation of active substance in the fly ash with action of excite and catalysis of the excitant and the water-proofing agent, thereby greatly enhancing compactness and water proof impervious capability of the tunnel concrete, and raising engineering quality.
