The method generally adopted to increase the durability of precast concrete piles and pipes carrying sewage is called as
1). Autoclaving
2). Ocrate Process
3). Derusting
4). Carbonation
One of the important surface treatments adopted to increase the durability of concrete is known as ‘Ocrate Process’.
In this, concrete member is impregnated with Silico fluoride under pressure.
Ocrate Process has been adopted to increase the durability of precast concrete piles and pipes carrying sewage.4. If x = 2/3, y = 4/5 and z = 22/125, then find the value of A. If A = (x + y)% of y ÷ z.
