Dear sir,
Kindly sent me design mix for M100 and above & right now i am tamilnadu ,we are manufacturing sfrc manhole cover. I am finding difficulty to get test certificate ,so kindly suggest me some lab with this infrastructure.
Thanking you,
With warm regards,
Ranjithkumar c.m
please i need a list of structural project topics that have recently been worked upon
What are the proper methods to repair a post tension foundational slab? The slab is used for a house and the one end has settled creating some floor cracks.
We have constructed a RCC sump , but it is leaking Kindly give some ideas to arrest the leakage.
We have constructed one I T Park project in Mumbai having three continuous blocks, seperated by 25mm wide expansion joints. The plan area of each unit is 5000 Sqm ( 70m x 72m ). The RCC roof have been constructed in slope of 400mm from the ridge having RCC gutter on both sides. We have carried out Brick Bat Coba water proofing treatment over the roof slab duly tested for any leakage by water ponding. This is a Gold rated green building project. Hence the thermal insulation treatment have been done from the top and over that membrane water proofing treatment also have done by the client’s for terrace gardening. But after completion of the thermal insulation and membrane water proofing, we are finding leakages from the roof. My question is ‘ whether this is a correct method’. The cross section of the total treatment done over the roof slab are as follows :
1. RCC Roof slab
2. B.B.coba Water proofing treatment over RCC roof slab.
3. 100mm thk thermal insulation boards fixed over B.B.coba by adhesives.
4. Geo textile cloth placed over the insulation boards.
5. 1.5 – 2mm thk membrane
6. Geo textile cloth over the membrane
7. 50mm thk concrete screed over geo textile cloth for protection.
8. over the screed gardening soil will be placed by providing suitable drainage system
We find the screed concrete developed cracks in many places and rain water finding its way through the cracks.
I would like to have an expert comment about the suitability of the system & the leakage problem.
im a b.tech student..we have a competition n we should build a concrete boat that floats n it is tested by adding weights… can anyone please give me suggestions on how to build n the mix designs..
Is there any book to learn staad pro software

Please can you tell me what the term ‘scarificial matter’ relates to many thanks Irene
To Irene
Scarificial protection means it sacrifices itself to protec another material. Take paint as an example to illustrate it.
The main component of painting system which serves to inhibit corrosion is the primer
because it is in direct contact with steel surface. In general the primer is
pigmented with inhibitors like zinc and zinc phosphate which protect the
steelwork by sacrificial protection. Initially the primer is porous and the
products generated by sacrificial protection of zinc fills these voids and the
primer acts as a barrier.
sir,,i have to work upon a project named culvert design..sir,pls tell me the key points to be considered while designing,,please sir,,ill b very grateful..
To ananya
Please read my book “Mastering Different Fields of Civil Engineering” Chapter 4 Part II on box culvert.
Sir in the calculation of BBS. of beam if the top reiforcement is in odd nos. and bottom in odd nos. then how we are going to place the 4 legged stirrups in the beam. EG. There are 5 nos. of 20mm bars in the top and 10nos. at the bottom. Please send me a graphical suggestion.
Sorry your question is not understood. it is better you present your question in graphical form.
sir,i am doing civil engg 3rd yr(5sem) in diploma.I would like to go for higher studies. i live in kolkata.i wish to study b.tech.i have some queries-
1.how to go to b.e/b.tech through diploma
2.how shall i prepare ?is there any relevant coaching centre or individual coaching in kolkata surroundings,please recommend .
3.name & address of the colleges that permits lateral entry.
any one can told about formula for to fing out air circulation area in a building.
Hi. Sir im an b.e student.. I wanted to know how the multistoried structure is built on a black cotton soil..
To Suraj
Please define properly “black cotton soil” before I can answer.
Black cotton soil is one of the type of soil sir.. like laterite soil etc..its can found in northern part of karnataka..
Hi, What is difference between FAR (Floor Area ratio) and FSI (Floor Space Index)
To Sudesh Kumar Siwal
They refer the same concept. The Floor Area Ratio (FAR) or Floor Space Index (FSI) is the ratio of the total floor area of buildings on a certain location to the size of the land of that location.
Different countires use different terms to refer the same thing.
Australia: Floor Space Ratio
UK: Plot ratio
Hi,
Can you help me calculate the SBC of a rock when the compressive strength of the rock is known
Thanks
To Satish
Please state long form for SBC to avoid misundertsanding. Thanks!
hi sir,my question is about the dia of tremie pipe used in casting bored piles.in our site we are using 150mm dia for 20mm aggregate..but,it gets choked inspite of cleaning the tremie now and then.the contractors proposal is to change the dia of tremie pipe to 250mm.i referred the bs8004(7.4.5.4.2d) where nothing in particular was mentioned.is there any ratio or table for check this?what are the demerits in using a larger dia ?further what are defects that may cause in piling?
To shabu shah
Aggregate maximum size for reinforced placements by tremie method should be 20mm so your proposed concrete mix has reached the limit of aggregate size. Fine aggregate content of 45 to 55 percent by volume of total aggregate and entrained air content of up to about 5 percent are generally desirable.
The second factor in influencing blockage is workability of mix. A slump of 150mm to 230mm is commonly used, but a slightly higher range may be needed when reinforcing cages restrict the flow or when horizontal flow over long distances is required.Please check if your concrete mix meets the workability requirements.
Another factor is the size of tremie pipe. Tremie pipe diameter usually ranges from 200mm to 300mm. Obviously, your original design of 150mm is too small to avoid concrete blockage.
I want to know what is the minimum & Maximum reinforcement tonnage required in one Cubic meter of concrete.
To Arun prasada
Different min. and max. area of reinforcement are specified in code and it depends on the structural type, steel types and the purpose of reinforcement.
For example, in beams minimum percentage of reinforcement (tension)for 460MPa steel is 0.45%. Maximum area of reinforcement is 4% of gross sectional area of concrete.
Please refer to concrete design codes for these details.
In estimating,what are all the items we can calculate the sub items quantity by means of the primary items measurements.For example by having the wall quantity we can able to calculate the other items like plastering & painting like this in what are the items we have possibilities.
