Hi guys, I am currently facing an issue of water damp in my building. It's so frustrating. I have broken the plaster about 2 feet above the ground in the interior, and it has risen to the upper part within 2 months, causing the screeded wall to peel off. I am completely tired of maintaining and maintaining a new house. I need your advice please.

olukaygold: But 1:2:4 will not even give you the minimum required strength for most reinforced concrete applications. If most reinforced concrete work. I use 1:2.5:3.5 which will give characteristics of concrete compressive strength of 25N/mm2 after 28days. Also, the water-to-cement ratio is so important. W/C of 0.5 which will translate into 1 bucket for one bag mix should be the way to go. For example, if Mr. A uses a mix of 1:1.5:3 with too much water, 1.5buckets, and Mr. B uses a mix of 1:2.5:3.5 mixed with 1 bucket, the strength achieved by Mr. B will be better than that of Mr. A with all things equal. In summary, quality control is as important as the volume of cement used in concrete production. Also, I experiment with mixes and carry out tests from time to time. 4 Likes 1 Share

Slimszy: Good evening Sir, was your house built on DPC or DPM?, Is the height of the floor of the surrounding compound same level, lower or higher than your building? |

Slimszy: Dampness is a big problem with most Nigerian homes. The primary case of dampness in buildings is capillary action. This is a phenomenon where water around the wall areas rises through the wall through this action. The primary way to prevent this is to institute a dampness program during construction. If the site has a high water table, properly drain the foundation, use moisture barriers on all walls, and create a damp-proof membrane on the ground floor before the oversite concretes and provide a french drain to take accumulated rainwater from the building perimeters. For this case, you will need to constantly remove water from the building perimeter using a french drain. Then peel the plastering up to around a meter high from the foot of the building, and replaster this portion of the building with a cement-riched plaster (1:4, one bag of cement with 6 parts plaster sand and 2 parts sand) also add a water sealant cement to the mix. If you can also paint the external wall with water sealant paint it will also help 2 Likes 1 Share |

abdulwastecx: Good day engineer, pls if am not wrong ur 1:2:5:3:5 means, 1 bucket of water, 1bag of cement, 10 headpan of sharp sand, 6 headpan of soft sand, 10 headpan of Granite Pls correct me if am wrong! Also how many litres of water is ur 1 bucket equivalent? |
Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by abdulwastecx(m): 10:53pm On Oct 14, 2022 |
Akerewe: I think 1 bucket is 25liters. It's one bucket of water to one bag of cement. Let me use this simple calculation to buttress the point. assuming that you want to use a Water/cement ratio of 0.5. Hence for 50kg of cement, you will need 25kg of water. Since the density of water is 1000kg/m3, and mass = density x volume. since one bucket is 25litres = 25/1000 m3 mass = 25/1000 x 1000 = 25kg. hence 25litres of water is 25kg. Also to the final question that you asked, 1:2.5:3.5 mean for every bag of cement ( which is 2 head-pan (flat) 5 head-pan of sand ( flat the surface, don't hip it) 7 head-pan of gravel (flat the surface don't hip it) 3 Likes 1 Share |

abdulwastecx: Oga Abdul, your 1,2.5,3.5 gives you M25 grade concrete.. That's 1 cement to 5 sand to 7 aggregates.. Do you use additives? Or could it be the 42.5R cement? Or the size of the aggregates? I know it's 1.1.2. that's guaranteed to give M25.. I use 1,3,4.5 for my bungalows.. I get up to 18 -20N/mm² after 28days.. |

Re: General Topic Thread-To Discuss Anything And Everything in Building Construction by abdulwastecx(m): 12:58am On Oct 15, 2022 |
KolaShangOne: The magic here is grading, limiting the water-to-cement ratio to 0.5, proper curing and proper vibration. If these variables can be controlled properly I think, 1:3.5:4.5 can easily be achieved. I've been using this mix design for some time now and whenever I carry out a test on the cured concrete I always get over 25N/mm2 I think I will have time soon to discussed and shared some of my findings soon. 2 Likes |

abdulwastecx:Like I said earlier, depending on the kind of strength the builder wanted to achieve but in building code of Standard,her Mixing ratio of 1:2:4 is Grade A mixing ratio which is generally acceptable as Standard mixing ratio. |
