Geopolymer decorative brick from fly ash and concrete residue According to this invention It consists of fly ash and concrete residue ratio 80 20% by weight. Together with the concentrated base solution, it consisted of 10 molar concentrated sodium hydroxide (NaOH) solution mixed with 60: 40% sodium silicate solution (Na2Si03) by weight, starting with sifted fly ash and concrete residue. 140 μm sieve, then sodium hydroxide (NaOH) is mixed with distilled water to a concentration of 10 molar (M) and then mixed with Sodium silicate solution (Na2Si03) with a ratio of 60: 40% wt to obtain alkali activator solution 24 hours before, take 'to 'fever The sifted fly ash and concrete residue were mixed at a ratio of 80: 20% by weight, then mixed with an alkali activator solution at a ratio of 1: 0.4. When mixed well, pour the mixture into acrylic mold. Then wrapped in clear pilm, incubated at room temperature 27-30 degrees Celsius for 7-28 days ------------ ------ 15/12/2017 ---- --- (OCR) Page 1 of number 1 page Invention summary.

When mixed well, pour the mixture into acrylic mold. Then wrapped in clear palm, aged at room temperature 27-30 degrees Celsius for 7-28 days ------------ Decorative bricks, geopolymer from fly ash and concrete residue. According to this invention It consists of a ratio of 80: 20% wt. Together with a strong alkali solution consisting of 10 molar concentrated sodium hydroxide (NaOH) solution mixed with 60: 40% wt sodium silicate (Na2SiO3) solution by The The fly ash and concrete residue were sifted with a 140 (106 (formula) m) sieve. Next, sodium hydroxide (NaOH) was mixed with distilled water to a concentration of 10 molar (M). Mix with sodium silicate solution (Na2SiO3) at a ratio of 60: 40% wt to obtain alkali activator solution 24 hours prior to use. The sifted fly ash and concrete residue were mixed at a ratio of 80: 20% by weight, then mixed with alkali activator solution at a ratio of 1: 0.4. After well mixed, the mixture was poured into acryl. Click and wrap with transparent film, incubate at room temperature (27-30 ํ C) for 7-28 days:
