Method for temporarily prolonging coagulation time of water-stable mixture

The invention relates to a method for temporarily prolonging the setting time of a water-stable mixture, and belongs to the technical field of building materials. The invention discloses a method for temporarily prolonging the coagulation time of a water-stable mixture, which is characterized in that white sugar is added into the mixture, and a large number of polyhydroxy groups contained in the white sugar can be adsorbed on tricalcium silicate particles which are not hydrated in time, so that hydrated calcium silicate crystals formed on the surfaces are destroyed, the formation of the crystals is prevented, and the effect of prolonging the coagulation time is achieved; in addition, the straw is used as a base material, and the surface of the straw is modified by using polydopamine and boron nitride, so that catechol and amino are introduced into the surface of the modified straw, the surface hydrophilicity of the straw is improved, the interface performance between the straw and the mixture is enhanced, and
