Concrete strength al ൯ne for an 10 thick wall with 5 10 and 2 5 clear to strength steel will only reduce the nominal moment capacity of the secti對on from 136 68 to 135 66 inch kips 尩 if the concrete strength decreased from 3 5 to 3 0 ksi.
Concrete blocks are formed in steel moulds using relatively stable materials enabling the size of individual units to be controlled to within small tolerances.
