Multiple layer composite material consisting of cement-bound concrete and polymer-bound concrete and method for producing the same

The invention relates to a method for multilayer composite material and preparation method thereof. The vacuum closed a layer of water at least cement and adhesive layer of water at least one polymer coalescence. The layer of water and polymer agglutination's of cement and region of the layer of water at least three two small strength of the material is. The layer of the steps of polymer coalescence the patient transgression of water, and no can permeating of liquid water. The vacuum closed to prepare the water with factor.
