dense state then the influence of water content (w = 0, 1, 2, 3%) on the shear strength and on the mechanical characteristics c and φ of clean sand and finally the influence of the preparation method on the shear strength of the sand-silt mixtures with a fines content 0, 10, 20, 30 and 40% and water content in the dry and the wet case. 2 Laboratory Test Program 2.1 Tested Materials The tests were carried out on the sand of Oued Chlef (Chlef, Algeria), containing 0.5% of non-plastic silt with I p = 5.02%. The sand was sieved to 0.08mm to obtain the fines, and

Investigating The Water Absorbance of Different Insulation Materials

Abstract

In this work, the moisture absorbance of 6 different building insulation materials are inspected in a laboratory environment. After being dried to a constant weight, the materials were exposed to five different, equally distributed, relative humidity environments, ranging from 0% to 100%. At each chosen relative humidity range the weight of absorbed water content was measured. Then the results were analysed. The insulation materials were then ranked using results from this and the author’s previous work.
