Block moulding 1. One trip of sand 2. 30bags of cement 3. N800/bag to mould the block We actually get 30blocks/bag and we get 30bagsper each trip of sand Total blocks per trip of sand = 900blocks The block is stronger and cheaper by N50/block

Thanks for this info. Is the trip of sand 5 ton or 10 ton? I want to ask you how many trips of 5 ton sharp sand can set (not mould) 5000 blocks? Thanks |
Re: The Construction Of 14 Class Room At Emuhoa Community Rivers State by abdulwastecx(m): 5:46pm On Mar 26, 2015 |
micbjrex: A bag of cement will set 60blocks using a mix ratio of 1:6. You need 83bags of cement for the 5000blocks You need about 25tonnes of sharp sand to lay the block 1 Like |

Thank you but what about materials for doors and window From your post, I understand that I will need 20 rods for the longitudinal pillars, 15 links.....i dont get that part, please help break that down in layman's term, 12 bags of cement, 1 ton sand, 3 ton gravel then for the 2 arcs, i need 3 rods, 2 bags of cement, 1 bar of Y8 rod, then use from the above sand and gravel. please, help do the math for pillar base mat and doors and windows too..thanks |

Re: The Construction Of 14 Class Room At Emuhoa Community Rivers State by jfkenny(m): 10:10am On Mar 28, 2015 |
abdulwastecx:Thanks and do justice to these: 1.What is the correct cement :sand mix for laying blocks. 2.I always read 1:2:4 as standard for concrete mix but I have not seen the builders implement such. what I normarly is 1 bag of cement:8head pans of sand :10headpans of stone. Or sand and stone will be made equal 8:8. Thanks and b blessed. |
Re: The Construction Of 14 Class Room At Emuhoa Community Rivers State by abdulwastecx(m): 12:11pm On Mar 28, 2015 |
jfkenny: In order to achieve a minimum concrete strength of 25N/mm2, a mix ratio of 1:2:4 ( 1bag of cement to four head pan of sand and 8 head of gravel. The sand most be clay free, The gravel must be retained on 20mm sieve. Water for the mixture must be drinkable and water to cement ratio can either be 0.45 or 0.55 Note the following: 1. The more the water content of a concrete the weaker the concrete 2. Most of concrete strength comes from the coarse aggregates (gravel) 3. Cement serve as a binder 4. Sand help to filled the void space between gravel and increase the volume of concrete The correct mix for laying blocks is 1:6 One bag of cement to 12 head pan of sharp sand . 3 Likes 1 Share |

Re: The Construction Of 14 Class Room At Emuhoa Community Rivers State by jfkenny(m): 2:30am On Apr 01, 2015 |
Sir in 1:2:4, will the sand and cement be able to bind the stone if the size of the stone is bigger than gravel.. Sir which is preferred: constructing an overhead tank for baths separately on mounting the tank on top of the building in a bungalow.. |
Re: The Construction Of 14 Class Room At Emuhoa Community Rivers State by abdulwastecx(m): 9:41am On Apr 01, 2015 |
jfkenny: it is cheaper to mount the over head tank on top of a platform (slab) Constructed on top of the building floor rate is a function of height ( Known as head in hydraulic). all you need to have sufficient head is to locate the tank at higher level than the bath. It is important to plan properly for this and to design the columns and beam supporting the platform. 1 Like |
