SBR Latex Modified Polymer Cement Mixtures for 3D Concrete Printing and Its Manufacturing Method

摘要

The present invention relates to a SBR latex-modified polymer cement mixture for 3D concrete printing. By appropriately mixing SBR latex, a water-soluble high molecular compound, to cement, it improves fluidity, extrudability, lamination and open time to facilitate printing and compressive strength. , Flexural strength, modulus of elasticity, drying shrinkage, etc. are improved, so it is possible to secure the safety and durability of the printed structure. The present invention not only facilitates construction by obtaining properties before hardening, particularly suitable fluidity, extrudability, lamination, and open time, but also properties after hardening, especially compressive strength, flexural strength, modulus of elasticity, drying shrinkage, etc., are improved and printed structures Stability and durability can be secured.
