| description |
Research was done to investigate whether the addition of nanoclay influenced the
properties of the rice husk ash/kaolin based geopolymer coating composite in fire
resistance and bond strength. This geopolymer coating composite that mostly consists of
silicon and aluminium are activated by alkaline activator which are the combination of
sodium silicate (Na2SiO3) solution and sodium hydroxide (NaOH) solution to produce
the coating resin.
The preliminary works were initially done in order to obtain the best mixture proportions
of geopolymer coating composite. The sodium hydroxide molarity of 8 M, 1.0 ratio solid
to liquid and 5.5 ratio of alkaline activator were chosen as the control parameters while
the ratio between rice husk ash and kaolin was varied.
The fire-retardant test results showed that with 20:80 of rice husk ash to kaolin, better
fire performance was obtained as the temperature at equilibrium of that coating is 230°C.
The fire performance of geopolymer coating composite improved with nanoclay addition
and the maximum of bond strength obtained was 3.48 MPa. These performances were
seen in samples with 3 wt. % of nanoclay addition. However, the adhesion strength of
the geopolymer coating composites were not majorly affected by nanoclay addition. |
