How to Make a Standard Cement Block
Transcript of video:
“In this episode we will be visiting a block making factory to see how to make a cement block – the standard way.
Every industry and profession abides by a set of rules, guidelines and standards that ensures best practises in all of it’s operation. In like manner, there are rules
guiding the making of cement blocks. Therefore, we will be exploring these simple basic rules.
First things first. Storage is key. It is important to pay attention to the storage of all the production components. Cement should be stored on a raised platform in a suitable
weather tight condition building. Sand should be stored in an open and clean environment and protected against clay, dirt and organic matters. Water should be store in
galvanised steel or plastic tanks.
Mixing each of these components in a measurable and consistent proportion is also important and is the key to the quality of the cement block that will eventually be produced.
One bag of cement to four wheelbarrow measurement or eight handpans measurement of sand all manual mixed. This should be done about six times – that is, dry mix three times before adding water and wet mix three times after adding water.
Scoop the mixture into the vibrating machine for compaction. Let the cement blocks form and air cure for 24 hours and then water cure by spraying with water for 7 days before stacking. Note that stacking should not be more than five courses high.
Deji Ola (MD/CEO Doff Signatures Architecture and Planning), “The quality of that vibration also help to compact materials together to give you a very awesome well vibrated block. Now, once it’s been produced, you need about 7 days of cure, of continual wetting of water on them so they gradually gain strength until it gets to a point when these gain full strength. Beyond that you can also supply to construction sites for use. The quality of curing, the timing ..(?).. much the strength of you block at the end of the day. So if you know that you are going for the best quality and it’s important to adhere to standards. If the block is being used in load bearing points, then it’s important that during the course of production, the production house has submitted (?) about the minimum weight that that block should have because it’s serving as a weight carrier – that is why we call them loadbearing, because they are carrying weight. There are areas where you could lay the block where they are not load bearing so you are not (?) about it but you realise that most people are putting a premium on getting the right blocks especially when you are using them for load bearing points.””
