- Luigi Cassar, an Italian chemist, invented self-cleaning concrete in 2013 using titanium dioxide (TiO2) which breaks down nitrogen oxide (NOx) pollutants into powder when exposed to light and heat. The TiO2 process oxidizes NOx gases into powdered NO and NO2 particles, cleaning the building surface. The mix design is similar to m20 grade concrete but with 3.5-4% TiO2 added to the cement. When water rinses the surface, it cleans away the powdered NOx particles, keeping the building depolluted without other chemicals. Self-cleaning concrete has been used in tunnels, pavements, and building surfaces as an ecofriendly way to

Self cleaning concrete
Self-cleaning concrete uses titanium dioxide to break down air pollutants like nitrogen oxide through a photocatalytic process when exposed to sunlight or UV lamps. This converts the pollutants into inert particles that can be easily rinsed away with water. The concrete was invented in 2013 and has been used in buildings, tunnels, and pavements in several countries. It helps reduce air pollution and corrosion while keeping the concrete surface clean without the need for chemicals or pressure washing.

Rainfall intensity duration frequency curve statistical analysis and modeling...
Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.

Applications of artificial Intelligence in Mechanical Engineering.pdf
Historically, mechanical engineering has relied heavily on human expertise and empirical methods to solve complex problems. With the introduction of computer-aided design (CAD) and finite element analysis (FEA), the field took its first steps towards digitization. These tools allowed engineers to simulate and analyze mechanical systems with greater accuracy and efficiency. However, the sheer volume of data generated by modern engineering systems and the increasing complexity of these systems have necessitated more advanced analytical tools, paving the way for AI.

Self cleaning concrete2.pptx
- 1. Self cleaning concrete -AN ECOFRIENDLY THOUGHT PRESENTED BY CH. INDRAJA B181923
- 2. Introduction Self cleaning or depolluting photo catalytic concrete, by the name itself it shows its affordability. The name that it looks like futuristic ideas and some of us may think that it is possible. But it is practical now, many foreign countries are stick to the concrete for its unbelievable beneficial results.
- 3. Luigi cassar(the innovative inventor) Luigi cassar( Italian chemist) invented the self cleaning concrete in 2013. Got European inventor award in 2013. He invented the fabulous concrete in italicement.
- 4. Nitrogen oxide(the foreign intruder) Nitrogen oxide NOX is the air pollutant which presents in the atmosphere more amount due to smog, smoke, vehicle, emission etc.
- 5. Why titanium dioxide(TiO2) Titanium dioxide is the only component which makes the building effectively non polluted. TiO2 through its process of oxidizing the NOx into NO andNO2 in powdered form it makes the building depolluted.
- 6. The mix design Similar to m20 grade concrete. Addition of 3.5% to 4% of Tio2 to the 96.5%of cement. Without any other chemical admixtures.
- 7. Procedure to be followed Light and heat are the main source. Make sure these hits the concrete. Automatically the reaction takes place. Then the gaseous particle break down into dust particle. Rinse it with water to make it clean.
- 8. The operation of self cleaning concrete Once the sunlight is falls on the building the UV rays of certain range will allowed to fall on the building. Photocatalytic process Tio2+Nox+sunlight. The hazardous gas becomes powdery particle and stays over the building like a dust.
- 9. After the process Water plays main role as a source of rain fall or manual cleaning. So clean the concrete with the water. Or otherwise it was self cleaned by rainfall and makes the building non polluted. Water droplets rinsing the NOx dust.
- 10. Before and after
- 11. Tunnels and pavements Tunnels are most denser atmosphere. Due to this larger air pollution occurs by vehicle. UV lamps are used here as source. As well as pavements also provided by self cleaning concrete.
- 12. Some of the tunnels and pavements
- 13. Buildings in the concept of self cleaning concrete
- 14. Merits of self cleaning concrete Reduces NOx content in atmosphere. Keeps the concrete young. Depollute other pollutants. Eco friendly. Reduces depletion of ozone layer. Reduces corrosion and patch formation in the concrete.
- 15. Conclusion Photocatalytic concrete materials have been used in horizontal and vertical applications. Inventors are the one who invents and engineers are the one who makes it comfortable to the environment. Using the articles like self cleaning concrete it is possible. It is preferable to use self cleaning concrete as an ecofriendly approach.
- 16. Thank you
