Why is water absorption of timber higher than brick?

  Answer: 1.2.1.1 Water absorption of given brick = weight of water / weight of dry brick Or, Water absorption =( 366.5 - 355 )/ 355 = 0.03239 = 3.239% 1.21.2 Moisture content = ( Mwet - Mdry) / Mdry = ( 56 - 34) / 34 = 0.647 = 64.7% 1.2.2.1 The main difference between the moisture content and water absorption is that moisture content means concentration of water wapour and other gases present in the material whereas water absorption is amount of water in liquid absorbed by the building materials. 1.2.2.2 A building material should not absorb water more than 20 %. Water absorption of timber is higher than that of bricks because of imbibition properties in dry wood. 1.2.2.3 Moisture content in timber materials can be as high as 200 % and as low as 0%. Our aim is to keep the moisture content of timber materials below 20%. Thanks for reading 📚 😀 comment on the post if you have any queries.
