Q:What are the low cost of using lightweight brick partitions and gypsum board partitions? Labor costs and materials costs together

Light steel keel gypsum board wall construction is simple, single gypsum board partition wall total cost is low, but its strength, moisture and water quality is far less than light brick wall, brick wall is not only high labor costs, and wall follow There are mortar of the process, than the stone to wear Cao Fei 丨 crossing to kill intestinal paste board wall complex many.

Q:What is the difference between packing density and bulk density in building materials?

in the material volume Porosity: Porosity is the percentage of the volume of voids between the particles in the volume of the bulk material in a container Porosity (Hollow Rate): Percentage of the ratio of the sum of the volume of holes and slots of hollow bricks and hollow blocks to the volume calculated from outside dimensions the higher the relationship density, the greater the apparent density, the smaller the porosity The greater the porosity, the apparent density is not necessarily small, the density is not necessarily small The greater the porosity, the greater the bulk density The greater the water absorption
