About Paper:

Air pollution has evolved into a severe global environmental problem [1]. Air pollution has been linked to being the source of numerous respiratory diseases. When inhaled, particulate matter can lead to several respiratory diseases and be the direct cause of premature deaths [2]. The construction sector is one of most countries' most prominent contributors to air pollution. While recent technology of the 3D printing of buildings using various build materials like geopolymers have been researched to reduce setting time and improving strength, the dust emissions and health risk associated from the entire process have been merely addressed in the available research. The conventional concrete production has dust as one of the primary airborne pollutants formed but recently 3D printing of buildings have been introduced using various build materials. Construction 3D printing using various build materials is actively being researched to achieve higher strength, faster settling time and better layer cohesion of the material. This particular research focuses on three different materials used for 3D printing which includes geopolymer mix composed by TAMUQ team, CyBe material, and another material developed under the collaboration between TAMUQ and DCP. Even though using these materials can potentially improve the concrete properties, it is unknown about the concentrations of dust produced during the different activities of making the structure. Therefore, our research would target to measure the dust concentrations with the particle sizes of PM 10 and PM 2.5 produced during the mixing, printing, curing, and finishing phase of these 3 different materials. Once all the data is collected our goal would be to compare the measurements to the air safety standards set by Health Canada.
