Abstract

The inorganic polymer, e.g. geopolymer, is well known as a green construction material with its remarkable mechanical and durability properties compared to other ceramic and Portland cement-based materials. It is worth promising to explore such geopolymer properties processed by a recent innovative technology, i.e. 3D concrete printing, which has established its ground in the construction industry. This study is focused on examining the directional effect of 3D printing process on compressive strengths of geopolymer mortar made from different industry by-products such as fly ash, slag, silica fume, etc. For a comparison, the same geopolymer mix was casted and cured in ambient temperature prior to its mechanical test with printed samples. Results from experimental tests revealed an anisotropy in the compressive strengths caused due to layered deposition of the geopolymer mortar.
