Abstract: An attempt is made in this paper to reduce the foundry slag's environmental footprint by recycling it. Recycling is a key concept of modern waste management and is the third component of waste hierarchy. While most of the foundry industries manage to minimise its waste, the difficulty exits with the small scale industries. Foundry slag which causes series environmental issues when disposed as land fills is the prime focus of this paper. This paper paves a way of disposing this waste by partially replacing cement with foundry slag in cement concrete to prevent its disposal into land which pollutes surface and ground water. To achieve this ferrous slag waste from foundries is replaced partially with cement in concrete. Experimental investigations are carried for M20 and M25 grade concrete. The mix design is carried out by Indian standard method. The properties of fresh concrete are measured in terms of slump, Vee-Bee and Compacting Factor to find the workability. The test on hardened concrete properties such as Compression, Tension and Flexure are carried and the results are compared with the conventional concrete. The experimental investigations are carried in M20 and M25 grade concrete. From the experimental results it is observed that foundry slag can be partially replaced in concrete for cement.

CONCRETE VEE-BEE CONSISTOMETER METHOD(IS 1199) DEMO BY SACHU
Переглядів 226 тис.13 років тому
This deals with the determination of consistency of Concrete using a Vee Bee consistometer, which determines the time required for transforming, by vibration, a fresh concrete specimen in the shape of a conical frustum into a cylinder. Demostration of the test conducted in Concrete Lab, Department of Civil Engineering, Bharath University, Chennai.
CONCRETE COMPACTING FACTOR TEST (IS 1199) DEMO BY SACHU
Переглядів 89 тис.13 років тому
Procedure for determining the workability of concrete ,where the nominal maximum size of the aggregate does not exeed 38mm.This is designed primarily for use in the laboratory,but if circumstances permit, it may also be used in the field. It is more precise and sensitive than the slump test and is particularly useful for concrete mixes of very low workability as are normally used when concrete ...
CONCRETE SLUMP TEST DEMO BY SACHU
Переглядів 76 тис.13 років тому
Slump Test- This method of test specifies the Procedure to be adopted, either in the laboratory or during the progress of the work in the field, for determining, by the Slump test the consistency of concrete, where the nominal maximum size of aggregate does not exceed 38mm. Demonstration of the Test conducted in Concrete Lab, Department of Civil Engineering, Bharath University, Chennai - 73
U r sach a great teacher... U have so much clearity to explain concept
Helpful ❤

Compaction factor test ua-cam.com/video/gsLulA9s6JI/v-deo.html
Compaction factor test ua-cam.com/video/gsLulA9s6JI/v-deo.html
Nice try. He clearly tamped 26 times after the second layer was added, invalidating the test.
Woooh
Hindi me bolie
Watching it in 2022 n learning. Thank you
narrator's Voice triggers the shit outta me.
Come on that's bit rude. Man is just trying to help us.
Who else watching in 2022😅😅
Thanku sir ❤️
Very well demonstrated
traduccion tienen, esta hablando en indu?? creo y no entiendo
The video demonstration is good 👍 But u not mentioned what the value is for which type Here i can say to all of you Vee bee time 32-18 sec than this is Extreme dry Vee be time 18-10 sec very stif Vee be time 10-5 sec stif Vee be time 5-3 sec for stiff plastic Vee be time 3-0 sec workability plastic 👍
Thanku sir for this best explaintion
Wonderful explanation.
Xlent sir
Thank you 🙏
Can't we add sand + coarse aggregate + cement
ua-cam.com/video/4lbI-cBhkm8/v-deo.html
Simply good 👍👍
Our college... Miss the lab
Great stuff! So how long must the concrete take to change to a cylindrical shape during the vibration process to ensure better workability?
thanks a lot sir for this. really helpful
Pls discuss the result
Sir why compacting rod is not used
Good explaination
Compaction factor = weight of partially compacted concrete/ weighg of fully compacted concrete =W2-w1/W3-w1 Where, W1= weight of an empty cyclinder W2= weight of cylinder + weight partially compacted concrete W3 = weight of cylinder + weight of fully compacted concrete ✌😀
Sir you can explain me civil engineering concepts basiclu
Which admixture are used in the experiment
I mean the final reading..
Sir...wt is the avg.time taken by the concrete to be levelled after switched on the machine....?
Very nice 👌 thanks 👍
Good job Thank you 😊
Aur banao vedio ku bnd kr dia vedio bnana
English speaking and pronunciation is poor...
Thank you, it helped a lot. 👍😇😇
Nice slump... True slamp
Nice
Nice vedio.👌👍 Very helpful for students...
Good explanation
Tanks sir
How to find final reading? Pls guide me!
When we start vibrator we should start stop watch to notice the time required for concrete to spread over the cylinder container due to vibration
@@vudavath3618 good explanation
Superb explanation
Fantastic mind blowing
Thanks
points you forgot to mention being a civil engineer: 1. Grade of concrete. 2. Weight of the concrete ingredients: cement, fine aggregate, coarse aggregate and water. 3. Size of Coarse aggregate and zone of fine aggregate.
Thanks
wonderfull explanaition
very nice vedio. Thanks.
