Barryton: Don't get me wrong o.. Not all white sand have high salt content. All those construction companies have a particular mining site and must have analysed properties of their materials including sand and applied possible treatment before using it. If you prefer the white one, find white one with the properties you need and use it. Aesthetics is also a good reason for preference. 2 Likes |

I think the issue of sand is said many times here, the only way out of sand is knowing the purpose. for concrete avoid Lagos sharp sand... use odo ogun or Stone dust, Lagos dredging sharp sand or soft sand is best use for setting of block, moulding of blocks, |

megacontrol: I think the picture is clearer now. You are right about insignificant settlement with your adopted foundation (pile). settlement in deep foundations like yours is very infinitesimal. You can go with your choice of filling sand, but be mindful to compact fully in three layers and damp proof properly to eliminate permeability.......preferabely 'double layer' since according to you the site is water logged. Of course you and I kno this measure wil save the occupants the stress of running away during rainy season like most landlords and tenants in Lekki/Ajah Sorry for the delayed response though and good luck in your project!! |

KolaShangOne:@emboldened Who get that time, i no be julius berger oo. lol Maybe because lagos is a riverine area, reason for the salty sand. We don't experience it in my area in Edo state. Maybe because of presence of less river, both the white & red like sand are used for concrete works. |

KolaShangOne:This is not true. Sharp sand is sharp sand. What u just described is soft sand recommended for block work & not sharp sand. u are mixing it up, sharp sand for concrete works & it is different from soft sand. There is a distinct difference between sharp sand & soft sand. What u have mostly in lagos is soft sand & not sharp sand. Pls do your research. |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by johnson232: 10:29pm On Apr 15, 2018 |
Barryton:What they have in lagos is best classified as soft sand & not sharp sand. |

EgunMogaji: Rubbiish: By my knowledge, it is sharp sand that is more susceptible to expand or contract with or without moisture. This is because of its large particle size. The bigger the particle size the more water each particle can absorb. This is the main reason rocks undergo weathering which eventually gives sharp sand and much later soil. In laterite, plasticity index increases and decreases that causes the soil to flow or reach its liquid limit. This happens because water takes up the space between individual particles of the soil. This is the main reason clay soils crack when dry. Modified Talking about waterlogged areas, i know the practice in most places is using sharp sand. It is a very bad practice for several reasons. 3 of the most prominent reasons are 1. Porosity 2. Low shear strength 3. Low density All these problems with sharp sand are eliminated with proper COMPACTION of laterite at its OPTIMUM WATER CONTENT making laterite the most suitable filling material. Note the words in bold, they are very important to achieving the maximum density which directly means high load bearing. At the long run, a proper filling with laterite will cost an arm and a leg. Most people plan would temporarily solve the problem but not permanently, hence sharp sand. |

EgunMogaji: I did my undergraduate project on soil and its engineering properties. I read a lot of engineering literature on the subject apart from the laboratory research i did. |

Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by adanny01(m): 4:02am On Apr 16, 2018 |
EgunMogaji: I know you disagree, these things are not always what they seem. It is like getting an online diagnosis for certain symptoms but nothing beats physical examination by an experienced Doctor. Porosity is the reason sharp sand looks like it doesnt expand but infact it is most affected by water than laterite. I did permeability tests on laterite that made me sleep in the lab during my UG project. Like i said with the modification, you need to do proper compaction on the laterite and it beats sand any day any time. Have you ever seen sand on road construction? In fact, if you meet a sand deposit on road construction you have to remove it same way you would with clay. Think of it this way, sand allows water level to rise within it but properly compacted laterite stops water level.Water is the enemy here. 1 Like |

Hmmm, this is an example of the concern i raised earlier about myth or individual practices being adopted over time as industry standard process/best practice without technical justification, or like in this case scientific research. Although this is argument is difficult to accept as it completely turns everything on its head, but who are we to belittle your body of work. I actually would love to read excerpts of the report if you don't mind sharing with me privately. I understand geology in general so i get your point on porosity and permeability. Just to be sure,which sand do you refer to as sharp and laterite in this case? adanny01: |

Walins: You will have to find out the price in your area but in my area its a bag at #700. Types of aggregate material determines the mix and preferred number. On a general note (foundation stage/ sub-structure)) 6" blocks(solid/hollow)------------30/35 blocks 9" blocks (solid/hollow)----------20/25 blocks You can increase the number by +5 afterwards for after foundation stage. 1 Like |
