Construction Particulate Matter Concentration Data

The presented data is obtained from a systematic experimental investigation of construction activity (i.e., building a solid concrete block wall). The experimental activity was executed from 3:20 to 4:00 (i.e., 40 minutes). The preparatory works such as arranging the monitoring stations and conveying materials are conducted during the initial 4 minutes. The mixing task was executed within 16 minutes (i.e., 3:24 to 3:40). Solid concrete block laying was executed in 20 minutes from 3:40 to 4:00. The sensors were kept at an 1 m horizontal distance from the PM source and 0.8 m vertical distance from the ground level. The samples are collected at 2 seconds time interval for all the sensors. The first worksheet contains PM10 concentration measured by Alphasense OPC-N2 sensors. The readings are filtered to 10 minutes moving average and presented from the beginning of the activity start time only. PM concentration measured by A1 and A2 sensors shows a higher correlation during the mixing task as both of them monitored the mixing task directly. The second worksheet contains PM10 concentration measured by Sharp GP2Y1010 sensors. The readings are filtered to 10 minutes moving average and presented from the beginning of the activity start time only. PM concentration measured by D1 and D2 sensors measured the same trend during the activity.
