Can anybody tell me about the reactive powder concrete. Is it a good topic for research?

what is the simplest definition of ion exchange capacity

What this unit identifies for the ion exchange capacity ca. 0.92 meq. g-1. I am a newcomer in the membrane area. I just started. I highly appreciate your help

Can we classify HV and LV lines based on line length?

I have dataset which shows the length of power lines. I need to classify the lines based on the line length. Is there a rule to classify the High voltage (HV) and low voltage (LV) lines based on...

Resistor definition in Piezoelectric bimorph with ANSYS workbench

Hello, good day! I am trying to simulate similar bimorph piezoelectric harvester with below commands. However, the output power doesn't change with resistor value. Please help to find the reason. ET,10,CIRCU94,0 !SET UP RESISTOR R,1,100000 !RESISTANCE VALUE TYPE,10 !SET ELEMENT TYPE E,1,2 !CREATE RESISTOR BETWEEN NODES 1 AND 2 Thanks in advance Regards,

Hi... To get more details about the Reactive powder concrete goto this below web link. This site is maintained by BTCM Div., Civil Dept. IIT Madras.

Me too is working on this Pozzolan effect but trying to work out with something else other than silica fume. I had my thoughts on Fly ash. Compared to other powder, FA has been one of popular approach for Pozzolan effect. What say you?

Ashutosh Kumar

Ya we can use fly ash but it is not going to be a new research, it is only change of one material and the basic concept is same . And there are different types of f.a, all are not contains goog percentage of silica.

When I was at Structural Engg Research Centre, I had carried out considerable research on RPC. Please be in touch with me, if you and your college/dept is serious to work on the topic.

Emanuela Emanuilova Manolova

Hello, I am a Ph. D student and my thesis is related by Reactive Powder Concrete, so you could find an interesting information about the application and the idea of this special concrete, on this web site: http://www.ductal-lafarge.com/

Yes, ductal is known sinve long.

RPC requires deep understanding of particle packing (Larrard, Dewar, etc), special mixing tool, besides excellent selection of ingredients. At my earlier time at CSIR-SERC, we could reach 250 MPa strength level. Ms Emanuela Emanuilova Manolova can share her actual title and details of the work undertaken.
