Alkali-activated slag with 3D printing waste: Self-heating potential pretests
Original language description
The basic premise of self-heating function of construction materials is favorable electrical properties, which is not fulfilled in the case of common geopolymers, cementitious or alkali-activated materials. To gain self-heating ability of such materials, an optimized amount of metal- or carbon-based admixtures is used to form electrically conductive paths which in case of higher amount of admixture results in a significant increase in electrical conductivity. It was reported at low voltage load an outstanding self-heating ability of cementitious composites with nickel powder. Nevertheless, such composites are of high environmental impact due to cement and nickel production. Therefore, it is beneficial to seek promising self-heating construction materials based on byproducts or wastes. The paper is focused on metallic 3D printing waste characterization and the determination of electrical and thermal properties of alkali-activated slag mortar with 3D printing waste. It was proved by measurements of electrical properties and confirmed by measurement of volt-ampere characteristics in the range of 40 to 100 V that even a high dosage of 3D printing waste admixture rich on nickel alloys, that the effective electrical conductivity of the composite is not sufficient to allow meaningful self-heating ability.
