The invention relates to a preparation method of special-shaped
polymer structure reinforcing composite light-weight
cement, relating to a preparation method of composite light-weight
cement and aiming at obtaining a light-weight high-strength
cement building material. The preparation method comprises the following steps of 1, preparing a special-shaped
polymer structure; 2, preparing
cement slurry; 3, forming a light-weight cement
composite material. The preparation method disclosed by the invention improves the reinforcing mechanism of the cement-based
composite material from the independent reinforcement of a discontinuous reinforcement phase into the synergetic enhancement of a continuous reinforcement phase by substituting a continuous
polymer special-shaped structure network for a discontinuous polymer
fiber, thereby effectively enhancing the usage property of the cement-based
composite material. The preparation method disclosed by the invention effectively reduces the weight of the material by 40%-50%, does not change the flowing property of the
cement slurry, can be used for freely designing the structure of the reinforcement phases and integrally forming the composite material and a prefabricated structure, has the advantages of simple preparation process, low cost, high designability of a technical process, abundance in used
raw material and the like and can effectively reduce the weight of the cement
building material.
