Experimental Study on the Mechanical Properties of the Fiber Cement Mortar Containing Polyurethane

Polymer is a kind of high molecular elastic material. The polymer cement mortar composite material formed by mixing it with cement mortar has the advantages of light weight, high strength, and good durability compared with traditional mortar materials. The effect of polyurethane polymer content on m...
