Love this topic,i having been thinking same too,cos no one no the mixing ratio of this so called vibrated blocks.
i prefered to mould blocks than to buy,but time and supervision is a hidrance here.

I have an idea i tend to use when am set for my projectprobaly next year,a block industry is directly opposite ma plot so i will arrange with
the guy,that is i will but cement,buy water and sand then i will ask them to moould for me,i will only pay cost of moulding which is about 700#/bag.
abi wetin una think,by so doing i will get the desired strenght and good mix i want.

how do i creat a topic on this forum

am interested have car been painted before,whats ur last price

This affect me too,at times when i finish spendoing i feel like cry.because i have to
wait till another month end.
But i think am working on this though.
