Study of Efflorescence on Different Types of Bangladeshi Bricks and Relation between Degrees of Efflorescence with the Type of Bricks

The work presents a practical investigation on the degree of efflorescence on different types of bricks available in Bangladesh. A relationship between the type of brick and degree of efflorescence is observed. The study is performed on five different types of samples. For this purpose the general procedure for a brick production is followed by making two samples of customized brick from two di...

Prompt deliquescence and efflorescence of aerosol nanoparticles

Literature reports have differed on the possibilities of discontinuous and continuous (i.e., prompt and nonprompt) deliquescence and efflorescence of aerosol particles in the nanosize regime. Experiments reported herein using a hygroscopic tandem nano-differential mobility analyzer demonstrate prompt deliquescence and efflorescence of ammonium sulfate particles having diameters from 6 to 60 nm....

Deliquescence and efflorescence of small particles.

We examine size-dependent deliquescence/efflorescence phase transformation for particles down to several nanometers in size. Thermodynamic properties of inorganic salt particles, coated with aqueous solution layers of varying thickness and surrounded by vapor, are analyzed. A thin layer criterion (TLC) is introduced to define a limiting deliquescence relative humidity (RH(D)) for small particle...

Mitigation of efflorescence of wallboard by means of bio-mineralization

Cement-based material is one of the most versatile and largest amounts of building materials which can not only be used in load-bearing structure but also be used as decoration materials, like brick, wallboard, and tile. However, white calcium carbonate always be found on the surface of wallboard. This phenomenon is generally called efflorescence, which has no damage to wallboard, but has aesth...
