Concrete block molds could last approximately 80000-10000 cycles, however, this totally depends on:
If raw material used are gentle to the mould( i.e. round river sand and pebbles such as round stones). Mould lifespan will increase, crush granite/stone with hard edges will cause abrasion to the mould, thereby decreasing its lifespan, hard raw material will also decrease its lifespan.
Vibration time & pressure:
Some products require a higher vibration time( to achieve higher strength of products) an increase of vibration time increase the abrasion to the moulds causing the decrease in its lifespan.
Some products required high precision (i.e. pavers) thereby the mould might not be useable within a short period of time. However if precision of products are not important(i.e. hollow block), a deviation of 2 mm on the moulds will still enable the mould to be usable.
