Abstract |
The objective of this study is to find out variations of indoor air quality according to application of environmentally friendly and absorbent materials which can be applied to sites at the construction stage of buildings. 2 construction sites were chosen for environmentally friendly and absorbent materials tests. The test for environmentally friendly products was carried out at 6 units(the most excellent grade of HB mark and EO class of KS at 3 units and the excellent grade of HB mark and E1 class of KS at 3 units) for 71 days and the other for absorbent materials(J and S productus) was done at 3 units for 183 days. VOCs(volatile organic compounds) and formaldehyde were sampled and analyzed by GC/MS and HPLC. The results shows that VOCs concentrations with the most excellent grade were lower than that with the excellent grade but a difference of formaldehyde concentrations between E0 and E1 can not be found through the test of environmentally friendly products and it could be said that J product is better than S product comparatively through the absorbent materials test. |
