So if you have any query regarding the concerned matter, just drop a comment and we will try to solve it as soon as possible.
sir,
I want to information about “relation between liquid limit and resistivity “
Could you please send me document on the importance of test on structure piles and foundation ie pile intergrity test, concrete rebound test etc, detail methodology, equipment requirement, data analysis/calculation and report writing guide.
Thank you.
Sir,currently i have started my project on permeabillity studies on nano cement……so i wish to know where i could get the references.details or any ideas of my topic
To Saran
Nano concrete involves the use of carbon nanotubes into concrete. In addition to increasing toughness the nanotubes, which are thousands of times thinner than a human hair, are highly conductive. As such, they could be used to create a nervous system within concrete that could be used to detect cracking and weaknesses in structures.
hello
i am designing a bored cast in-situ pile foundation for a transmission tower and i need to know the deflection criteria for the same and it would be great if you can refer me to any standard which gives details of the safety in bored insitu piles
thanking you

Please clarify the following detail:
1. How many(%) laps/Splices can be used in a raft of 5 Mtr X 5 Mtr? Please mention the particular IS code which is being taken into consideration.
what is meant by friction grip bolt?
To Nagappan
High friction grip bolts are commonly used in structural steelwork. They
normally consist of high tensile strength bolts and nuts with washers. The
bolts are tightened to a shank tension so that the transverse load across
the joint is resisted by the friction between the plated rather than the bolt
shank’s shear strength.
HSFG bolts have the following advantages when compared with normal
bolts:
(i) The performance of preloaded HSFG bolts under fatigue loading is
good because the prestressed bolts are subjected to reduced stress
range during each loading cycle when compared with unloaded bolts.
(ii) For structures adjacent to machinery which generate substantial
vibration, preloading bolts can help to avoid the loosening of bolts.
(iii) HSFG bolts are used in connections where any slight slip movement
would render the integrity of the whole structures break down.
(iv) Owing to its high tensile strength, it is commonly used in connections
which require the taking up of high flexure and the tensile stress
generated could be readily resisted by it high tensile strength.
i am doing a project in school an it involves me asking a few questions about civil engineering so if you can answer these short questions it will be great.
where this type of engineer might work? duties and resposibilities for this engineer? what made you want to be an engineer? what is a typical day on the job like? any personal advice?
Hi, how r u?, there are now dayz new courses in some universities “Civil Engineering Design”, so please can u tell me about its scope, job opportunities???.. thanks.. and waiting for your reply??
hi, i am in search of a nice seminar project on SEISMIC ISOLATION DEVICES. can u please help me out with it. please reply soon
sir,i am doing civil engg 3rd yr .i am to deliver a presentation on DAM after a week ,,so would u plz provide me a material,if possible.
To mriganka,
Please be specific. You can’t expect that that I can write down 20 pages of information about DAM here.
plz suggest me also how can i improve the skill of my presentation ?
Sir, I just took over a concrete paver making plant. I am having problem with my mix design. I have gone through the old records there is no standard mix. my mixer capacity is 1cu.m is there a standard mix for concrete paver or can use mix design 1:2:4. I have to get the compressive strength to 49N/mm2 in 14 days
can you please advise how do i go about these.
To Chelladurai
Without standard mix, please go through the followings steps of designing your required grade of concrete:
Step 1. Set a target mean compressive strength, fm
Step 2. Obtain required material information, including availability of materials (what kind of aggregate and cement available), sieve analysis of both coarse and fine aggregate, BD, UW and MC of aggregate, and maximum size of aggregate.
Step 3. Determine the w/c ratio
Step 4. Specify the slump value. Usually, slump values of the concrete to be designed will be specified according to the job nature of the concrete construction. Determine free water content.
Step 6 The cement content can then be calculated by dividing the water content by w/c ratio.
Step 7. The total aggregate content is then obtained by estimating the wet density of the fully compacted mix
Step 8. Determine the proportion of sand. The proportion of fine aggregate to total aggregate depends on the grading of the sand and maximum aggregate size, the workability and w/c ratio.
hi
Iam a civil engineer with 4 yrs experience in designing field (petrochemicals)
Now I want to work from home due to some personal reasons. Please suggest me how to get work which can be done from home. I have experience in foundations, RCC & steel structures. softwares: Good exposure to Staad Pro, autocad and handful experience in manual designing
I have to give a presentation on ‘quality control of construction’
please provide me relevant material as soon as possible.I am eagerly waiting.Thank you.
i want to do softwear (cad ,cam,stat pro……….)related job plzzz say how can i get present i am doing civil3rd year ……….&which softwears iwant to lern
can i get the weight calculatiopn of steel sections of angles, channels, beams etc which are manufactured by, SAIL, VIZAG, TATA ESSAR or jindal. as the weights of rolled sections are lesser compared to the above manufacturers.
To Rajat
Quality control (QC): A management function whereby control of the quality of (a) raw materials, assemblies, produced materiel, and components, (b) services related to production, and (c) management, production, and inspection processes is exercised for the purpose of preventing undetected production of defective materiel or the rendering of faulty services.
Quality Control is defined as “the part of quality management focused on fulfilling quality requirements.”
Another definition of quality control descibes it as “the process relating to gathering process data and analyzing the data to determine whether the process exhibits nonrandom variation.”
Quality Control often referrs to Inspection of finished products, meaning to check whether they meet the desired Requirements and Specifications. But it is not limited to inspecting products as it might also include detecting the cause for non-conformities and not meeting the requirements documented in the specifications for the product.
In all production processes, the extent to which products meet quality specifications must be monitored. In the most general terms, there are two “enemies” of product quality: (1) deviations from target specifications, and (2) excessive variability around target specifications. During the earlier stages of developing the production process, designed experiments are often used to optimize these two quality characteristics.
quality assurance (QA): 1. All actions taken to ensure that standards and procedures are adhered to and that delivered products or services meet performance requirements. (188) 2. The planned systematic activities necessary to ensure that a component, module, or system conforms to established technical requirements. 3. The policy, procedures, and systematic actions established in an enterprise for the purpose of providing and maintaining a specified degree of confidence in data integrity and accuracy throughout the lifecycle of the data, which includes input, update, manipulation, and output.
In compaction test, the compliance criteria of moisture content of soil shall be within +/-3% of the optimum moisture content. If the measured moisture content is outside the range, what effects will it have on the compacted soil in the field apart from specification requirement non-compliance?
What value of compressive strength is expected if we are using following mixture proportion for concrete making:
Water (0.5): Cement(1.0): FA(1.45): CA(2.98)
185: 390: 568.87: 1164.12 for one cum concrete
We have a concrete tennis court, it has many potholes of about 2-3mm deep & 8-9mm in diameter. Kindly suggest best possible way to repair it
Thanks
