Abstract: A concrete crack repair material based on nano materials includes raw materials as follows: seaweed, sulphoaluminate cement, natural sand, nano-silica fume, calcium formate, fly ash, anhydrous calcium sulphoaluminate, a polyester fiber, a water reducing agent, a corrosion inhibitor and water. By reasonably selecting the raw materials of the concrete crack repair material and making a reasonable ratio of the raw materials, the concrete crack repair material is obtained with excellent performance such as good compressive strength, bending strength and bond strength, and excellent impermeability and frost resistance. The concrete crack repair material can be used for the concrete crack repair in the marine environment, which has very important application values.

Abstract: An interface joint material based on industrial solid waste includes raw materials in parts by weight: portland slag cement, 80˜130 parts; metakaolin, 80˜130 parts; the industrial solid waste, 80˜130 parts; sodium silicate, 25˜35 parts; alkali, 8˜12 parts; acrylate, 30˜36 parts; a trivinyl ether compound, 1˜3 parts; inorganic sulfite, 1˜3 parts; persulfate, 1˜3 parts; a water reducing agent, 3˜6 parts, and water, 60˜80 parts. The interface joint material is suitable for a concrete interface of different components, with good bonding, high strength, and the advantages of pumping, fast hard, early strength, micro expansion and high ductility; In addition, the industrial solid waste is added into the interface joint material, which improves a utilization rate of the industrial solid waste in construction joint materials, and has significant for recycling of the industrial solid waste.
