The cement base polychromy mortar accumulation of salt in the surface soil is a relative complex physics, chemically and physically chemical process.Different
Researcher has different understanding to the formation mechenism of the cement base polychromy mortar accumulation of salt in the surface soil, however what is accepted mostly is in mortar
The soluble-salt that the water translocation in portion and surface moisture evaporation are taken out of is caused by mortar surface forms white deposits, serious shadow
Ring decorative effect.The primary product CaCO of the accumulation of salt in the surface soil3It is mainly derived from two aspects：First is that being generated during silicate cement hydration big
Measure Ca2+And OH-, these ions penetrate into mortar surface with the migration of pore solution moisture content testing, with the CO in air2Reaction generates
CaCO3；Second is that water soluble alkali that the other components of mortar such as supplementary cementitious material, mineral admixture and additive itself contain and
Salt, these water soluble alkalis and salt form CaCO in mortar surface by a series of physical chemical change3.And CaSO4·2H2O、
Na2SO4、K2SO4On the one hand derive from mortar raw material itself, be on the other hand because portland cement in alkali content it is excessively high,
After corresponding mortar adds water mix, largely free Ca is formed2+、Na+And K+, Ca2+、Na+And K+With the SO in cement-based material4 2-
Reaction generates water-soluble alkali salt, these water-soluble alkalis are precipitated using water as carrier migration to material surface as moisture evaporates.
