A retaining wall is 200 mm (8 in) thick; the steel has 40 mm (1 1/2 in) of cover. What size aggregate should be used?
Homework Answers
For retaining walls and abutments the maximum size of coarse aggregate is 75mm.
According to Indian roads of congress the maximum size of aggregates should not be more than 1/4th of wall or concrete thickness i.e;200/4=50mm.
So,here maximum size of aggregate that should be used is 50mm.

A differential nitrogen pressure exists across a 2-mm-thick steel furnace wall. After some time, steady-state diffusion of the nitrogen is established across the wall. Given that the nitrogen concentration on the high-pressure surface of the wall is 5 kg/m3kg/m3 and on the low-pressure surface is 0.3 kg/m3 , calculate the flow of nitrogen through the wall (in kg/m2.h) if the diffusion coefficient for nitrogen in this steel is 1.0 ×10−10m2/s at the furnace operating temperature. Express your answer to three...
