I have a manual press machine. I did a soul test first to see what the clay % was. It tested at 80-85% clay. I then weighed in 5 gallon buckets for consistency of mix a ratio of 5.5 type m sand, 3.5 clay, and one part Portland cement. The water mix must be right also. If a brick breaks in the mold I found it wise to put it back in mix and reuse it after proper mix is done. You can’t pull a bad block from the machine unless there are obvious cracks if you do. I then air dry the blocks that same day and the next day I leave them in a tub of water for the next 20 days. I pull them out and air dry them for 3 days. When tested random blocks (1 out of every hundred at that point) it measured between 3500-3800 psi with 3700psi the most common rate. As I stack them I add rebar, pipes for electrical and plumbing, and other supports. Every meter I did a concrete beam across the blocks with rebar attachment. I also rebarred all windows and door frames and poured concrete there too. I did one course of brick a day until I got to the point of needing a scaffold system to lay block. Then I would need two days and as I got higher I needed more time. I used Portland cement to stabilize the clay and sand and block as a whole. Check out my TikTok (anteperic2) for comparison videos against red fired clay blocks and cinder block. Also my UA-cam channel has 11 videos for you to watch. It works if it’s done right.
I think you need good quality interlocking blocks professionally done and cured. Every brick is not just a good brick like every ndarugu stone is not necessarily a good stone. Passing a judgement without first telling us your technical know-how is peddling propaganda. Remember transport cost, labour and time are the key issues to consider. After setting the bottom block you do not need much skilled labor for interlocking blocks. They have global acceptance if you are properly informed.
Thanks. That was a good one for consumption. What happens when one is using ballast chips on masonry blocks production. Does the plaster hold or peel off. And is screening necessary before mixing considering that the chips have dust on them.
With the blocks you were making, you should be using a 4 gravel (1.6 to 5 mm screened), 3 washed concrete sand, 2 cement and 1 water formula. You should also have reinforcing rods running vertically through your wall, and the reinforcing rods need to be backfilled with cement through the cores. I would not use the hydraform blocks, as they are not able to be vertically stabilised via cores, as there are no cores on those blocks. The other benefit with 'cored' blocks and bricks is that you can run your services and utilities through the cores. This saves cutting into the wall to install the services / utilities.
I like the video. I think the problem of not holding plaster with interlocking bricks is because the masons maybe do not first chisel the bricks abit for the plaster to hold...May be they do it i dont know. Thank you for the video. Very educative
They break because 1. Ratio of cement to soil 2. Preparation of the soil eg seiving etc 3 . When building. Use a spirit level.the first block level need to be same level. On all axis. X, y and z for weight distribution. Something a quack with no engineering background can do
I will have to politely disagree with your conclusions here that interlock Brick are not suitable to build within Kenya, In South America and Asia they have been using ISSB for a long time with no issue at all and they are also in a tropical climate with a lot of rain even more that Kenya ... The issue with ISSB reside - 1. Manufacturing process - mix ratio - force of compression - curing process 2.- Construction expertise 3.- Foundation stability as all other bricks/Block A very good ISSB looks like a rock usually with 10% of Ciment as a stabilizer and up to 100 tonnes of pressure and properly cured for at least 3 weeks ... Thanks for your videos please i really enjoy them.
Hi I wouldn't disagree on the above input, I raised the above issues and when the above are all met I realized costs are similar with ndarugo,, then y go through with all this plus the headache??..
So to control the quality of the block you need to do the manufacturing itself, and the proper and more qualified fundis are more expensive, and for ndarugo you basically get fundis on the cheap and no hustle for quality control...nway financially speaking at the moment I still prefer ndarugo
@@mianomuthii Instead I would say this is a technology is new for us in Africa, we just need to understand the basic and grow from There ... Every country I have traveled to, they have at least standards for bricks and different pre-determined strength and size like Europe they have M150, M250 ... For different uses ... I will invite you next year to visit my factory, so you can see yourself what i'm talking about here
@@mianomuthii With good interlock Brick, they cost of construction is about 30% to 40% lower depend on the plan, usually you save on time, labor, Ciment (plasta & Mortar) and if 2 level even in structure depend of the architect... And other aspects like strength, water resistance, temperature control, quiet (sound proof), beauty and others ...
Hahaa am sorry about your experience, however we shall revisit this video in a few months time. We have an upcoming project that we'll be using interlocking bricks method. Meanwhile let's keep doing more research on the same.
The 15 shillings on the red interlocking blocks from MuMi is NOT the purchasing price but service price with your own materials. I have had a project with them now calling themselves JoMu interlocks and It was a good experience.
I am in the USA. I could not understand because the language was changing to swahili. I want to make an interlocking stabilized soil block (ISSBs) project iwth 90% soil and 10% sand. I would like to use Makiga's machine to do it. I have an architect's design of the building project. What do you think? about using ISSBs.
Okay, the most important part of blocks is the artisans and quality of blocks you make. The artisans Will determine both the quality of the blocks and building. Another thing to consider is the ratio of materials you will use. Like you still need a little of cement in the ratio for cement is a great binder or treat the bricks on an oven/kiln. Heat helps. After getting the building done don't leave the bricks exposed to the element without some sort protection especially from rain and termitez...
@@mianomuthii I would. try to ask people from the Makiga company to build it. Since they might be the best or they might have the most experience. The advertising about Makiga's Interlocking Stabilized Soil Blocks is very impressive. I would hope that the reality lives up to the advertizing. For example I would hate to find that after it is built it quickly deteriorates from insects and rain. Does it live up to the reality of all the advertizing ? or are there there some rapid deterioration problems?
@@gogexperience we can have a video call or virtual call on what's app anytime from 10am to 5 pm Mon to sat.. I could take you through some of my experiences
At 0:46, you are showing a masonry block - NOT a CSEB or ISSB. Those masonry blocks are made from plastic moulds, and are a wet pour block manufacture. Whereas the CSEB and ISSB are dry pour moulding, made in a press, then popped out. The thing that does not sit well for me with ISSB bricks is that, depending on the machine, they can either be inconsistent in either height or length. At this time, am in the process of building a screening table that is worked using a bicycle! Where there is no electricity available, burn fat, not oil! A wheelbarrow with the raw material sits outside of the machine. A second wheelbarrow sits underneath the screen and catches the small sized material. The required material is trapped on the screen, and the screen is removed from time to time to empty and replaced and refilled, one shovel at a time. I may change the design of the machine but to do that will require a third wheelbarrow. The next project after that above is the manufacture of a machine that will be able to make the masonry blocks mentioned above, CSEB and roofing tiles from the one machine! It may even be set up to produce large format paving!!! But, we see how things progress.
Seems you interlock bricks are very poor quality, I'm not sure what machine you use and your mix ratio ... Try a good quality interlock brick and compare ... Of course there are a lot of factors on saving especially on labors, cement, time and quality of construction... On durability, it depends on your techniques and know how ...
A best mix is A bag of 50kg cement, 5 wheelbarrows of soil (quality soil), 2 wheelbarrows of sand, and 2 wheelbarrows of lava debries. You will produce an evalasting interlocking block. I do not recommend the design you displayed there are other better double interlocking block designs.
Govt has hydraform machines in all 47counties. They provide the expertise which seems to be driving your conclusion. It is like saying one car is safer than the other because of one having a careless driver.
@@bkadenge like the footage of sand interlocking bricks you see it's in the government offices in kirinyaga county and they did lessons only for a period of,3 months and abandoned the project completely
I find your analysis shallow and biased. Interlocking bricks are teh way to go. If you have a machine it costs only 15 shillings per piece. It is faster to build and uses little plastering if you need to do that. Stones are expensive and cause environmental destruction.
But you never took best care of the project. So many projects of these bricks I've seen are bettering. In our Uganda kigo prison was built using them and it is ok. Anything however good it is, if mishandled can degenerate quickly. Same with life brother. Sorry for this but I disagree with you. Try good handling of them u will testify
True... Hi this soil bricks 🧱 were from a government project.. mine was the concrete ones and still doing fine... Just compared to the cost of building with this and stone I still prefer stone in Kenya... As cost is relatively the same and stone will definitely outlast the soil bricks
