When diesel drips on the slab, it doesn’t evaporate but rather soaks into the concrete. Diesel can evaporate but it is really really slow. A lot slower than water actually.
Infiltration and Evaporation of Diesel and Gasoline Droplets Spilled onto Concrete Pavement
Pollution at gas stations due to small spills that occur during refueling of customer vehicles has received little attention. We have performed laboratory experiments in order to assess the processes of evaporation and infiltration of fuel spilled onto concrete samples. Changes in mass of both spilled diesel and gasoline droplets as a function of time have been analyzed. The infiltrated mass is affected by variations in humidity, among other parameters, which influence the amount of water condensed onto the concrete. Therefore, we used a humidity data logger and statistical tools to predict the evolution of the real mass of infiltrated fuel. The infiltrated mass roughly decreases exponentially, but the difference in behavior between both fuel types is important. The percentage of evaporated mass is much larger for gasoline, while infiltration is more significant for diesel. Also, the percentage of infiltrated liquid depends on the initial droplet mass. We also developed a multiphysics model, which couples pore-scale infiltration to turbulent atmospheric transport, to explain the experimental data. In conclusion, a substantial amount of fuel could both seep into the ground to contaminate groundwater and be released to the atmosphere. More studies are needed to quantify the public health implications of the released pollutants.

FAQ
Will diesel evaporate off concrete?
How long does diesel last on concrete?
How long does it take diesel to evaporate?
What does diesel fuel do to concrete?
Does diesel evaporate?
Diesel fuel does evaporate. Its evaporation rate is slower than other fuels, primarily because it’s denser and more oily. Compared to most other fuels, diesel has longer chains of carbon atoms. Weak interparticle interactions exist in the diesel carbons. Diesel fuel changes its physical properties when it evaporates.
How long does diesel evaporation take?
Due to these varying factors, it is difficult to provide a precise time frame for diesel evaporation. Generally, diesel fuel evaporates more slowly than gasoline due to its higher boiling point and lower volatility. At higher temperatures, diesel will dissipate faster, as the fuel molecules gain more energy to escape the liquid surface.
Why does diesel evaporate faster than gasoline?
Generally, diesel fuel evaporates more slowly than gasoline due to its higher boiling point and lower volatility. At higher temperatures, diesel will dissipate faster, as the fuel molecules gain more energy to escape the liquid surface. In contrast, increased humidity and low air movement can slow down the process.
Does diesel fuel vaporize?
Although diesel fuel is less volatile than gasoline, it can still vaporize under the right conditions. However, the rate of evaporation varies depending on several factors, such as the specific formulation of the diesel fuel, the environmental conditions, and even the size of the fuel spill or the container in which it is stored.
