Producing Synthetic / Polymer Granite

01/14/2008 12:25 PM

Will some one give more information about producing Synthetic Granite -- to be made from Crushed Granite aggretgate mixed with Silica / quartz filler material and Epoxy compound.

1 What should be the mix ratio of aggregate to Epoxy. ?

2 For making the parts of desired size and shape with Minimum porocity what should be the particle size and mix ratio of Granite to silica / quartz ?

3 For making the aggregate with varying working life from 45 minutes to 120 Minutes what kind of retarders are to be used ?

4 Mixed agreegate after poring in wooden mould needs to be vibrated on Vibration platform and after curing needs to be removed from mould so what kind of Mould release agents are required ?

Above information is required for guiding Enginerring students for the project work by them.

If any company / consultant is offering services would like to know their details. Have already tried on Google but not much success hence this request

You are going to have to figure it out for your self.

If someone has the info they are probably in the business and would consider that proprietary. Sorry but you may just do a better job for your demographics.

You could try to get one of the manufactures to let you do some low cost research for them in trade for the info. And use vacuum during the vibration table to remove gas bubbles.

I've always thought a poured granite kitchen floor would be cool.

Think Terrazo, using a cement which is same/complimentary colour as the granite

plastic / epoxy binder = fail

since epoxies are very costly and poisonous to work with, polishing epoxy...?? not easy.

some types of stone dust are very poisonous, aside from silicosis. [wet grind only!]

if you're making tiles, buy them... cheaper by far since you will be hard put to compete with a factory. [< 3$ per sf wholesale in us, less in other countries]

custom counter tops etc? better check around.. those are done in overseas factories at a fraction of what you can do.

on site fabrication/poured? maybe..

then, polishing. thats where the factory or well equipped tradesman will excel.

diamond polishing equipt is a bit pricey. You can use ancient techniques if you have lots of cheap labor.

Granite and quartz are not a good choice for making artificial stones.

More (confidential) information is available:

type of natural stones that give good results,

size-distribution and mixing,

type of epoxi,

reinforcements and attachments,

and more.

I was looking for a granite countertop in my kitchen and some company offered to make one with poured epoxy-crushed granite mixture in 2 days from measurement to installation. The artificial granite was to be only half an inch thick and would be poured on the existing countertop, but I found that the price for this was a little more than getting real granite installed directly over my kitchen cabines after removing my existing countertop, so I prefereed to get Corian in stead of Granite knowing that natural granite is porus and subjet to stains which Corian is not.

I think you want geopolymer resin binder, not plastic epoxy.
