The activators comprised a mixture of sodium silicate (Na2SiO3) and sodium hydroxide (NaOH). The geopolymerization process formed different microstructure and physical properties. This study aimed to determine the effect of alkaline activators ratios on the artificial aggregate properties for use as road and airfield pavement materials.

3. Stand the barrel on end and mix vermiculite and sodium silicate to a sticky mass and pack into the bottom to form a level surface and reduce the length of the inside. 4. Cast a layer of insulating castable across the vermiculite to form a back wall. 5. Cut a 6" hole in the wall of the barrel for the burner.

Sand castingWikipedia

Sand casting also known as sand molded casting is a metal casting process characterized by using sand as the mold material. The term "sand casting" can also refer to an object produced via the sand casting process. Sand castings are produced in specialized factories called foundries.Over 60 of all metal castings are produced via sand casting process.

The output results are achievable with a Weld current of 62.6148 Amp Frequency of 23.1821 Hz and Peak current of 65.9104 Amp. Using Die penetration test the weld joints were also classified in to 2 categories as good weld and weld with defect. This will also help in getting a defect free joint when welding is performed using GTAW process.
