I have read in the research papers that the solutions are to be mixed with each other one hour prior to the casting or else one day prior to the casting. The student just mixed the two solutions and poured it in the dry mix. An improper technique.

Is this related to hydroxide catalysis bonding of optical components?

Very interesting Can you comment on the long term structural stability of the Castings underwater or in wet conditions. Also has there been any leaching tests done to see if the alkali added is permanently bound to the Si-Al-O Matrix. Is it likely that under wet conditions the castings will lose strength?

Can you explain briefly...... About Geopolymer mixing

very strong stuff long lasting.

That lady should wear a mask when working with any fine/dust particles. Health and Safety first.

Its in India. Plus she is a woman. Sadly they are almost second class if my mempry is right. In short. Replaceable

What are the curing conditions?

How to make a geopolymer that does not use slag or fly ash???

hello how can i use plastic in cement . I want to make waste plastic roofs

Make concrete with raw polystyrene , mold, cure, and dip coat/ plaster on your melted recycled plastic outer coating.

Mix sand and plastic and heat it up until it’s like a paste, the press it into a mould

good

Link doesn't work

I couldn't understand the accent. Was heat used to cure?

The CC is surprisingly accurate. He says "Cured in controlled humidity conditions for three days". At a guess based on the time stated, I would say it's effectively slow cooked and humidity controlled in a dual purpose humidity/temperature control chamber at a relatively low heat. A google image search shows similar chambers, but not specifically the one shown.

super

Great ideas

My theory is this same technology is how the pyramids were built even these stone walls in Puma punku

David Shareef I highly doubt that. Geologists are shockingly good at identifying the formation processes of a fantastic number of different minerals. If those rocks weren't produced by a natural process somebody would already be a multi millionaire because of it.

Tadesan second off all u too are a fucking bozo the clown because Professor Joseph Davidovits (who came up with the Pyramids made out of GeoPolymer theory) has had man made (by his own hands) geopolymer cement tested in labs all over the world without telling them anything beforehand and not one detected it as man made. that is empirical evidence not to mention the ammonia build up inside of the pyramids which is a byproduct of heavy rain on poured geopolymerized limestone. its morons like u both why the masses never figure anything out

during thousands of years concrete turns into stone, concrete is just broken up stone its crystalline structure is broken and fuses into a giant crystal over time. the only way to create such precise stone laying and to create megalithic structure is by using Concrete.
