Idea

This application estimates the age of any construction based on observatory value and construction parameters. Since Construction Industry have variety of structures, so, primarily we will focus on bridge and consider expanding to other structure if time permits. The estimation is based on standard mathematical expressions for age calculations.

Motivation

Most construction projects are located far aware from organizations or companies promises. Construction Engineers when at site need to perform some test and get result immediately. The only device that is appropriate for such test is our mobile that can make instant calculation on the site .It is in view of this that we are developing “ageometer” whose main purpose is to help construction engineers to be able to perform test on concrete (bridge) to determine how long a concrete can stay (life expectancy) which include the ability to perform and get result on site everywhere without permanent physical connection to cable networks

Inputs

Crack information with Sensor/ Else picture processed with image processing techniques to detect the crack (obviously we are not proccessing the image now in this code camp)

Bridge Information from Archieve or Database or manual input

Cloride Ion Value of the Concrete Structure

Outputs

Mathematically calculated estimated age of the construction.

Description

This application makes easier for Construction Engineers to make a estimation of age of a concrete structure. Since the variety of construction structure is very wide, we would focus on only few structures.

The formula given below is for calculating the estimation age of concrete structure but to make it easier for our application we have generalized the formula :-

where:

C(x,t) = the measured chloride concentration at a desired depth,x;
Co= the surface concentration measured at 0.5 in below the deck surface, lbs/yd3 ;
t = the time in years; and
Dac= the diffusion constant, in in/yr.
The erf (y) function is the integral of the Gaussian distribution function from 0 to y.
