Method for improving durability of concrete through lime water
The invention discloses a method for improving the durability of concrete through lime water. According to chemical thermodynamics calculation of a carbonization reaction of the concrete and analysis of chemical constituents of pore fluid, a method that the lime water is sprayed to the surface of the concrete is provided by calculating the thermodynamics solubility product Ksp of Ca(OH)2. Due to the rule that Ca2+ in the lime water can not permeate into the concrete and can only be separated out in surface-layer pores, along with execution of the carbonization reaction, volume expansion is generated, the surface-layer compactness is improved; particularly, micro-cracks on the surface can be plugged, invading of harmful media is prevented, and therefore the durability is improved.
