A Comparative Study of Portland Cement-Based Materials and Hydraulic Cement-Based Materials for 3D Printing Concrete

Abstract

The issues related to construction remain unsolved. Three-dimensional (3D) printing concrete has capability to solve the problems such as cost materials and the need of skilled worker because this construction method is formless method. However, the technique requires specific concrete material for printing through print head, for example printability and stability. Therefore, this study is aiming to comparison of Portland cement-based material and Hydraulic cement-based material for 3D printing concrete. Hydraulic cement was selected due to less carbon emission that is sustainable material. Two cement materials were properly mix into concretes, then were carried out by flow table test, setting time test and compressive strength test. After that, the results were analyzed.
