My favourite GINGER,
We design such type of "rail-sleeper on ballast" with the help of the Reynold's Handbook on Reinforced concrete to get quick but slightly conservative solutions.
Dear krd,
I agree that the unit weight of concrete to be considered for the subject calculation shall be in the range of preferably 1MT/CUM (10KN/CUM) to conservatively 2.5MT/CUM (25KN/CUM). My opinion is that the liquid pressure height should be restricted to only the layer under vibration or...
Mr. boo1 (Mechanical)
Please briefly elaborate on the hydro blasting (w/ blast media), by which you had reduced the dust generation and waste disposal, for our use.
While we are aware that the active pressure on the cohesive soil is gh-2c, where g is unit weight, h is head and c is cohesion, if we apply this philosophy to the concrete we find that c is zero initially and increases gradually as the setting time increases. Hence we should worry only for the...
