Hire a welder to make you one, I had 2 made for only P2,000 each.

New, they sell for double and aren't as solid.

how much do u save when blocks are 7 php/Pr

 

You save a lot of stress from watching those 7 peso blocks melt in the rain before you even get to use them and you get the piece of mind of knowing how much cement is actually in each block.

after buying the mixer, mold, sand, cement how much do u save when blocks are 7 php/Pr ?

I pay P14.6 per 6" block here and because I have them made special to my specification with 3X more cement than their normal. But if you're only going to use say 2 to 4K blocks it may or may not be worth doing your own. But for me it would have been worth it having laid 18,000+ so far and a lot more to go yet. However, I had no place early on to store anything safely so buying was the only option. So, wanting to employ a family member is just about reason enough to do it all yourself and the cost of his salary will come off the saving on the blocks and you can monitor the quality of the mix etc as well. I'd tend to go with the weld your own option mentioned. The units for sale in the big hardwares here (Belmont) do only 3 blocks at a time and cost around P26,000 from memory but I might be wrong on the price as maybe it's half that??? Whatever, it's too expensive for a fairly simple steel structure.

If you want the best blocks you want the block maker at Belmont. It has a motor that turns an unbalanced shaft that shakes the hell out of the whole machine so the material compresses into to the mold much better than pressing by hand. I think the unit is about p17K and then you have to buy the steel bottom plates for I think p80 each. If you buy 200 plates you can make 200 block per day. It does only make 3 at a time and it takes maybe 2 minutes to make the 3. Then you raise them from the machine and set them aside to make another 3. Following construction, the machine can be used as a family business or the unit can be sold for not much loss.

 

On those little electric mixers, they really are kind of junk and only good for small projects. Not very well made and only do half a bag of cement at a time if that. And if you get in the middle of something and you have a blackout, it sucks.

its not a money saving thing .i can pay a relative who i know will do a good job to do it so he has a fair wage,i get good blocks so its a win win deal. im hoping to find a used one --some one did the same thing and now has no need of it and will be cheaper for me .

im also not in a big hurry so we can stockpile the blocks till we start building the second house .

 

and you right im tired of picking up blocks that ive bought and have them crumble in my hand . thats that story

IF you have the means the quality control you have to make your owe is worth it. When I started to build the contractor had made our own because we had only a long path to use all most cliff like to bring materals to the site. The blocks had to be rough and tumble or there would be nothing to use. In the end the mold form seemed to have walked. You can always use good blocks. I hear some places sell the better block meaning they use a litle more cement. Good Luck

The trick is to NOT make P7 blocks, but P25 blocks which would cost you double in the states and pound them together 10-12 times instead of the 3-4 times they do here.

They save money on materials by not pounding out oall of the air and not having to add the extra couple of scoops of cement mix to the new block.

As far as a cement mixer goes, it would be a waste of time because as thick as you have to make block mix, you would have to add water and remix off and on all day long, saving no time at all.

I make mine on the cement floor of my carport and set them on a plywood sheet in the shade of the carport.

Nice and solid, not crumbly as stale cookies.

I would have loved to have had that last year when I was armpit deep in block orders!

I didn't even know they sold them here.

make at no more than 35 blocks per 1 sack of cement,,,, It is custom here to make them 75 or more to one sack of cement. One must also be careful with the type of sand you use. Often it is beach sand which contains large amounts of salt, which will greatly eat away at your steel rebar and seriously weaken the concrete blocks. It is always best to get freshwater bank sand or quarried/pit sand whenever possible.

 

This is one reason I refuse to purchase a use home here in the Philippines. I will build my own concrete blocks and insure that the rebar is both of quality steel and of adequate size and spacing. Most homes here are only one good shake away from being a rock pile.

Yikes. I think the newly rebuilt gas towable one bagger mixers run about p45K. My guess is the rest of their prices are equally inflated.

Oh and I can personally make 150-200 blocks a day, with a 2 day head start for curing, I can stay way ahead of any single block layer here in the Philippines.

I have not researched block makers so i can not comment on the cost. I have however done extensive research into buying a mixer . A one bagger - new, with a choice of either diesel or gas engine runs just shy of 50,000 pesos .

Do you make 8x8x16 blocks ? Much better than the sizes i saw here as you can use them to pour columns(posts).

I made 6" and 8" blocks, the 6" blocks work well for interior walls and save a small amount of space for the rooms.

Not much, but even an inch can be a help when you consider the length and width of the rooms.

I sold my forms to a friend a while back, my heart condition keeps me too weak to do hard labor, the best I can do is to walk 5 miles a day at a leisurely pace.

If I had an electric block maker though, wow! I bet I could start making blocks again and would be glad to as there is little or no competition when it comes to hard blocks.

You are absolutely right, there is no need for a 8 " interior wall . if i had a heart condition i would stay away from any work involved concrete. very physicaly demanding , especially in a hot climate.

However, you might have a good idea for a quality block manufacturing..

My wife's younger brother was helping me, but it proved too demanding, but as I said, I could get along with the machine and her brother (he is a good worker) and start making a bit of money too.

I mean, one could put out a lot of quality blocks pretty fast with one of those machines and here I didn't even know they were sold here, even the block yards I learned from did them one at a time like we were doing.

You can buy, manual molds in most of the small hardware outlets downtown around the Carbon area.

 

I think that as soon as CHB is mentioned all, of the old fallacies start coming out.

 

There is absolutely no reason to make blocks stronger than 50 blocks per bag, and very little reason to use 6' blocks, unless the blocks are to be left exposed or used as "load bearing" walls.

 

A CHB, in a concrete filled and rendered wall is only a volume spacer. You could use polystyrene instead of CHB and the wall would have perfectly satisfactory integrity.

 

A mixer is imperative to mix adequately.

 

Cement and sand are mixed dry! Otherwise the cement sticks to itself, not to the sand, resulting in a weaker mix.

 

Using salty water or salty sand, is "not" detrimental to strength of CHB. But it will effect cure time because of the change in hydration. Once cured, the majority of chlorides will have been removed by efflorescence.

 

For steel reinforced concrete, in a tropical littoral climate such as is found in most of Cebu, reinforcing bar "needs" to be protected by an impermeable barrier. Epoxy coatings are recommended.

 

Concrete is porous and permeable, chlorides will migrate through concrete due to capillary action (from the soil) and hydroscopic pressures. It is a compound hydrate solid that will alternate between anhydrous and semi saturated. It is often this cycle that corrodes rebar by electrolysis.

 

If you haven't studied this stuff, find a qualified civil engineer who has, and pay him.

 

You can't just wing it, although most contractors here do.

Question is, how many can you sell monthly to make it viable biz ?

Tell me that when your 50 blocks per bag are cracking and mine are still solid.

Mine were 40 per bag and that makes a big difference in strength.

I talked to a lot of local block makers and theirs were averaging about 100-150 per bag!

I don't believe everything I read, but that's just me I guess.

Oh and most factory molds are expensive and flimsy.

A welder can make them to your specifications for only about P2,000 each.

I don't like having to buy only what is available, no true survivalist would.

I really haven't figured with the new machine I could get, but with the old one block, manual mold, I could break even in a month with about 300 block sales a day, but it took 2 days to get that many made with one man.

Manual block making is normally 200-300 per day if you rush, but if you want quality and take the time to mix, compress, etc. and do it right, maybe 150 per day.

I would had to have had 2 molds going to have done that, but sometimes things got slow so that wasn't a necessary action.

If we caught up on our 8" orders, we made 6" and had a small stock pile of about 1,000 of them.

The locals want 4" and 6" only, but I refused to make 4", too thin to support a 2nd floor as far as I am concerned.

I was getting P25 per 8" block and P22 per 6" block if that makes it easier for you to figure, also I was picking my sand up in the boonies (creeks in Consolacion hills), paying two guys P300 each flat multicab load which saved me quite a bit of money.

One really should split a barrell and rinse the mud and crap out of the sand though or the strength and color could be jeopardized.

Where is this block maker? We were looking at a used one a while back and it was more than that. Hmmm maybe I should sell the block makers?
