- What is the super plasticizer?
Superplasticizers are used to enhance the fluidity of the concrete without adding water.
Molecules physically separate the cement particles, these molecules temporarily neutralize forces of attraction between the cement particles. This gives the concrete much more liquid consistency.
Superplasticizer available at globmarble.com...
The power of TECHNOLOGY!! Great video, thank you for the knowledge!!
Thank you for the comment.
Thank you
nice
Excellent product. Could you use less water, example a/c: 0.20? that is, 1.8k of cement, 360g of water. It will give a little less fluidity, it will increase resistance! It's possible?
Yes, absolutely. The mix designs are very flexible. The superplasticizer just guarantees lower water demand in your mix, the consistency you wish to achieve is all up to you
Wait, 9 years and nobody noticed at 1:19 that 4 x 0.20 is not 1 but 0.8?
Can we use it for decorative objects?
flower pot, vase, candle holder etc.
Super))
Thank you! Cheers!
What would you recommend for making concrete sculptures (clay like workability)? Would super-plasticizer work? It looks too runny here (or just use less water)? Thanks. Also great video, very clearly showing the process and how the workability changes.
I would reccomend not using superplasticizer because its job is to make the concrete runny. Instead, use some 13 mm fibers and play around with water dosages until you get a consistency you like :) globmarble.com/alkali-resistant-glass-fiber-reinforced-concrete.html
@@GlobMarble will do thanks for the information!
but u dint add coarse aggregate in this one could i know that what strength will we get here ?
What would be the amount of cement and sand for your Veneer Stone Mold VS 101?
Every mold has the specific casting instructions in the description on our website. globmarble.com/veneer-stone-mold-vs-101.html
Hola que tal. Me gustaría saber si venden el plastificante. Gracias
Yes, we sell and ship it worldwide- globmarble.com/concrete-additive-water-reducer-super-plasticizer.html
Superplastisizer make what pce in add other chemicals pls reply
Superplasticizer reduces the amount of water you need to add into your concrete. This makes your concrete much stronger. You can buy it here- globmarble.com/concrete-additive-water-reducer-super-plasticizer.html
After use superplastisizer what setting time
Same time as regular concrete :)
Are you just using Portland cement as your cement
Yup!
Thank you for answering questions. I am in a Caribbean country where self-leveling mixes are not readily available. Can your super-plasticizer work with Portland cement and triple washed masonry sand to create an acceptable self-leveling underlayment?
Super plasticizer works with cementitious material, it doesn't react to sand or any other filler. You can definitely use plasticizer with Portland cement to cut your water usage and make your concrete stronger, but you will have to test plasticizer on your cement. We offer high quality plasticizer globmarble.com/concrete-additive-water-reducer-super-plasticizer.html with dosage rate 0.5-1% by cement weight. If you use other plasticizer, check dosage rate prior using.
Powder or liquid which is better?
It doesn't really matter powder or liquid, it really depends to your preferences. Make sure you get highly concentrated plasticizer for best result. We recommend this one: globmarble.com/concrete-additive-water-reducer-super-plasticizer.html
Hi, what's the average setting/working time from when its placed to when you can walk off job?
You can cast and walk off your job if you don't use fast setting additives :) Concrete can take anywhere from 8 hrs to 24 hrs to set, it all depends on what concrete mix is used, weather conditions, the size of the mold, and the amount of water used. The cycle time can be reduced further by using only enough water in the mix as is absolutely needed, or using a faster setting concrete mix. Make sure that the concrete has dried and hardened before you try to release it from the mold, concrete will shrink slightly, during the hardening process, and will be easier to remove, just turn the mold over and pull with even pressure from the edges, do not use tools to pry the part out, as this can damage the part and mold.
can i use the liquid super plastisizer in same ammount ? and liquid superplastisizer will work same or not ? and what if i use overdosing of superplastisizer what will be the effect of that on the copncrete ? after 28 days and before placing please tell me in breif
To prevent over dosage and get expected result, please check manufacturer's dosage instruction prior use other brand " liquid super plasticizer" . Our plasticizer dosage rate 0.5-1% by cement weight.
Hello sir
Can we use this super plasticizer in making gypsum molds
If yes what should be the ratio of water to gypsum to that of plasticizer
You can use plasticizer with Gypsum. We'll make the plasticizer with gypsum casting video soon.
@@GlobMarble thank you for your response
1:19 w/c ratio 0.2 4 x 0.2 = 1 buddy you need a better calculator, now because of that, I don’t know the exact w/c ratio, is it 0.25 or 0.2, huge difference there
Hey I am trying to use it on the outside of my basement walls. It is a bit difficult to use it there but it makes them completely vapor proof.
You're trying to apply concrete on the wall or its a bit difficult to apply casted stone to the wall?
GlobMarble Inc
Is this tile water proof? And what adhesive to adhere to wall, is it sound and thermal insulator?
The tile is made form concrete so there is a degree of sound and thermal insulation. Also, it isnt waterproof, only water repellant, so you can use a sealer on it to make is 100% waterproof. you can find our sealers here- globmarble.com/decorative-concretes/concrete-sealers/
Is there any difference in dry(powder) or liquid PCE based super plasticizer
The only difference is that liquid release has a higher chance of breaking and spilling during shipping :) This is why we sell powder release
Thank you
I have used superplasticizer PCE based of SIKA company which is available here in Pakistan but not getting the same finished surfaceas like yours
I have used same proportions and mixing pattern but result is nkt like yours
I am using silicone rubber mold
Sir can you give me your whatsapp no
I want send you the pictures
@@armkf2343 from where did u get the plasticizer from in Pakistan?
@@ahmedanwar87 sir i have got it from my friend working with vertex chemicals
hello. when i make tiles with this mix design there are many pinholes on the tile.my materials is the same(silaca sand-melflux-cement and water).when you pour concrete on the mold many air bubbles come on the surface but mine is very low. what's the reason? quality of cement? tnx
Hello. Can be quality of cement, your sand maybe not clean, you may need to mix little longer, you may need to add bit more water depends to your filler type..... It may be many reasons. Always make a several different tests with your material and select best working for you option.
@@GlobMarblehello again . this time add a basf defomer too in the mixture and mix longer time. what happened was that the concrete changed from self-leveling to a fixed concrete. is that because of defomer or over mix? what happens when concrete be over mix?
@@hamidrezar1040 I believe it because of defoamer. Please read the defoamer TDS
How thick is that piece you made in this video?
1/2 inch or 1.27 centimeters

Hi. Im having trouble getting the concrete to flow. How dry is your sand initially? (before adding water)
Sand has to be dry. if you have a wet send you should reduce your W/C ratio.
Send your mix details and material weight details to info@globmarble.com we'll figure out what you did wrong.
can you help me by telling me where I can get the superplasticizer product, thanks
You can order superplasticizer on our web site globmarble.com/concrete-additive-water-reducer-super-plasticizer.html
hello, I live in Brazil and would like to know the name of the plasticizer that is used in this video.obrigado
its a Melflux Super Plasticizer
thank you
@@GlobMarble donde puedo comprar el. Plastificante melflux
i just wondered, it is worked for lightweight concrete.
Yes, it will work for all concretes including lightweight concrete. Super plasticizer - its a water reducer for cementitious materials. Lightweight- just a filler
Can this be used with helix and icf.. did you send to get tested
Plasticizer can be used with any Cementitious type material. You can order any quantity to test at globmarble.com/concrete-additive-water-reducer-super-plasticizer.html
what is mould Model
MS 821 globmarble.com/concrete-stones/concrete-stone/mosaic-stone-molds/
Global, are you using portland or csa? And, what aggregate size - what silica size I mean? Thanks for your answers... Finally, what is the HSC end results in psi?
For this casting we used portland cement, sand, plasticizer and water.
We have another video with Portland cement and pure CSA, check the following link please ua-cam.com/video/PVK252n-SyI/v-deo.html . Unfortunately we didn't test it for PSI, but there is should be at least 10 000 PSI
Awesome - looking forward to doing more business with you.
GlobMarble Inc
In this case we used Portland cement, sand and super plasticizer.
we didn't use an aggregate. This panel is 1/2 inch ( 1.2 cm) thick, general purpose sand with different size granules works good.
You can try 1 part cement + 2 parts filler ( sand + aggregates).
We used 1 x 1 cement by filler in this case, our PSI more than 10.000. with 1 part cement + 2 parts filler and w/c ratio 20-25% you'll have close to 10 000 PSI
Dear, what is plasticizer in Spanish?
Sorry, don't speak Spanish
El- plasticiser

Is this as strong as GFRC
It's more then strong enough. You can reinforce the stone with fibers, but it doesn't make any sense. You can also make 1 part cement + 2 or 3 parts sand. All additives have to be re-calculated based on cement weight.
Use Metric!!!... International Standard
I like metric too, you can check out our website, there is a lot of cool stuff on there and all the info is available in both metric and imperial
