kopell:By laterite do u mean red sand? If that is the case comparing sharp sand & laterite for filling for waterlogged is not debatable because of its properties. Sharp sand is better. |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by kopell: 8:56pm On Apr 14, 2018 |
Rubbiish:is its sand, looks like red mod clay to me or what even its called. may be is better in my language oh, Amon pupa. Seriously I'm very curious that is why I asked the question. Sypder is the only one I've seen in one of his project that he used sharp sand to fill on one of his foundation here, most of the project displayed here are always using laterite in water logged area. |

kopell: That should be laterite. The issue with laterite is that it expands and contracts with moisture. |

Thank you. A soil test was done though, the result indicates that the immediate underlying soil is made of LOOSE GREYISH FINE GRAINED SANDS followed by SOFT DARK BROWNISH PEAT. Is compaction really all that necessary with a pile foundation? i am just wondering, given that the superstructure will be supported by piles which are connected directly to the hard rock deep down. this is why i think the filing medium will not make that much difference. there will not be significant settlement (if any) to the structure whether you use sharp sand or not. i stand to be corrected. for a two plots of land waterlogged seriously in excess of 1m, then you could easily be talking about over a million naira difference between this two choices of filling sand. if it were a raft foundation, then the type of filling sand takes a greater significance.

kopell:Lol...It's laterite. It expands when subjected to water, reason why it is bad for waterlogged areas. |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by megacontrol(m): 9:17pm On Apr 14, 2018 |
yes laterite is the red filling sand. Actually i was initially referring to two types of sharp sand, but it appears not many are aware of the other type. If you were using a pile foundation will you still use a sharp sand as against other cheaper alternatives Rubbiish: |

kopell: Sand generally are better filling sand, the sand here means soil with no cohesion. They are better because they compact readily, they don't swell or expand when they are wet and don't undergo secondary consolidation. 1 Like 1 Share |

akinolaolujide:Sharp sand varies but it is still called sharp sand, or do u have another name for it? It sharpness which affects its colour will definitely affect its sizes. The difference in name we hear are localize name given due to its location source, but they are all sharp sand. 3 Likes |

Please oh my people that stay on Lekki phase 1,lagos, how do you purify your water for bathing and cooking?

The main or important factor is really that one has salt content which is more corrosive to metals so odo Ogun sharp is more desirable than osa sharp but often times your location determines which one you have access to. p Rubbiish: 3 Likes |

Rubbiish:My Oga I don't think we should overflog this matter we all agree that there are different sharp sand . What we are simply saying is that these variations have different engineering properties and usage. Afterall tiles is tiles but we still have floor and wall tiles designed for different purpose. What we are trying to dissuade people is fallacy of hasty generalisation. As we all agree everything in construction has consequence. The quality of advice we give also have consequences . I will conclude like this granite might have a general name but I have it in different sizes. For different types of engineering. Job, same for cement. Even our local gravel.

You have demonstrated that you actually know more than the average "Nigerian Architect". This is much better than generalizing that sharp sand is sharp sand. This is the kind of logical and factual submissions that we need to encourage. akinolaolujide: 3 Likes |

Anything sharp sand is location, every local govt. in my place has its own sharp sand & each location will preach its own to be best. That's for newbies. But for me, i group all to be same. Apart from the colour of which some are white, all other properties are same. Particle sizes & salty content is inconsequential if u ask me. I have used all in my state & i can say they give same end results, just colour difference. So i don't give peference to any particular local govt. sharp sand. |

nokia46:Which areas of your house are u having these termites? |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by KolaShangOne(m): 2:37pm On Apr 15, 2018 |
nokia46: If you're in a termite infested area with surrounding bushes, you may have to treat your foundation or wood with chemicals periodically (say every 2 months), clear and burn surrounding bushes. If you have just mild attack, you can use salt and water solution, solignum, ravages and other chemicals.. I don't know if any plants prevents termites. 3 Likes |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by KolaShangOne(m): 2:40pm On Apr 15, 2018 |
Rubbiish: Well.. They are kind of different. Salt content in these sands differ. The whitish ones tend to have more salt which can attack the concrete and iron rods in your foundation. 2 Likes |

KolaShangOne:So it isn't advisable to use white sharp sand for concrete works? Because i do see big construction companies using it on bridges & i have always preferred it to the red like type because of its fine finish. |
