Porosity is an important parameter concerning clay bricks due to its influence on properties such as chemical reactivity, mechanical strength, durability, and the general quality of the brick . The amount of water a brick or a brick structure absorbs varies depending on the properties of the brick.
example, the Kozeny-Carman relationship relates permeability to porosity: K ~ e3/(1 - e)2/ where e is the total porosity and S is the total surface area of the pores. This equation requires a value for the porosity expressed in terms of pore surface area. Thus,
The heat and sound conductivity of bricks vary greatly with their density and porosity. Very dense and heavy bricks conduct heat and sound at a greater rate. They have, therefore, poor thermal and acoustic (sound) insulation qualities. For this reason, bricks should be so designed that they are light and strong and give adequate insulation.

Mar 21, 2002 · The ability of brick and masonry walls to insulate against sound transmission is an important design characteristic. How these properties are measures and how to improve the insulation properties of masonry walls are covered.
Sound Attenuation - The brick sound insulation is normally 45 decibels for a 4.5 inches brick thickness and 50 decibels for a nine-inch thick brick. Insulation - Bricks can exhibit above normal thermal insulation when compared to other building materials.
Common Commercial Concrete batching plant. The main types of common commercial concrete batching plant are: HZS120, HSZ180, HZS200, HZS225, HZS250, HZS300 which have advantages such as environmental-protection, energy-saving, high-efficiency, stability and safety.
Concrete shares the same soundproofing advantages and disadvantages of brick and is more cost-effective in many circumstances. While acoustic tiles are designed to help soundproof a room, bed comforters are cheaper and, therefore, more practical if you're on a tight budget. Adding insulation to drywall helps improve its sound dampening properties.
Partitions of Porous Materials. Double Wall Partition. Cavity Wall Type Construction. 1. Rigid and Massive Homogeneous Walls. A rigid wall consists of stone, brick or concrete masonry construction, well plastered on one or both the sides. The sound insulation offered by these rigid walls depends upon their weight per unit area.
