Underwater concrete and preparation method thereof
The invention discloses underwater concrete, belonging to the technical field of concrete. According to a technical scheme in the invention, the underwater concrete is prepared from the following rawmaterials in parts by weight: 35-45 parts of gravel, 3-10 parts of fine aggregate, 20-25 parts of machine-made sand, 6-20 parts of cement, 0.1-0.6 part of a polycarboxylate superplasticizer, 0.05-0.2part of sodium fluosilicate, 0.01-0.05 part of aluminum fluoride, 0.03-0.1 part of diethanol amine and 0.05-0.1 part of xanthan gum. The invention also provides the preparation method of the underwater concrete. The underwater concrete prepared by using the preparation method has the properties of low loss rate and rapid solidification, and can meet the requirement of rapid construction in seawater.
