DETAILED DESCRIPTION OF THE INVENTION
One skilled in the art will readily appreciate that the present invention is well adapted to carry out the objects and obtain the ends and advantages mentioned, as well as those inherent therein. The embodiment describes herein is not intended as limitations on the scope of the invention. The present invention is a solid geopolymer composite for the use as construction and friction material. A solid geopolymer composite comprising a pozzolanic mixture containing volcano ash and an alkaline activator is disclosed. In the preferred embodiment, the pozzolanic material employed is volcano ash. The volcano ash used is proven to be comparable to Class F fly ash in silica, alumina and iron oxide composition. Hence similar to the use of Class F fly ash, volcano ash can be used as artificial aggregates in construction materials and/or friction materials.
The volcano ash used is derived from volcano mud acquired in vicinity of volcano. The volcano mud is dried, grinded and sieved to obtain volcano ash in preferred particle size. Volcano ash with finer particle size has higher surface area of reaction
during geopolymerization, hence it is able to form a geopolymer composite with greater strength stability. Preferably, the particle size of the volcano ash used is in a range of 10 - 500 μπι. Further, sintered volcano mud can be utilized as volcano ash in the geopolymer composite. The content of silica and alumina in the sintered volcano mud is higher than the original volcano mud, therefore rendering it suitable for geopolymer composite. Nevertheless, the use of sintered volcano mud increases the energy usage during manufacturing process.
Preferably, the volcano ash is presented in the range of 50-80% by weight of the pozzolanic mixture to ensure a homogeneous mixture is acquired. In a condition where the composition of volcano ash in the pozzolanic mixture exceeds the preferred range, the pozzolanic mixture would be too saturated to cause a loss in workability of the geopolymer composite. On the contrary, a solid geopolymer composite would not be formed.
The present invention is a solid geopolymer composite from volcano ash that contains silica, alumina, metal oxides or a combination thereof. The existence of polymeric Si- O-Al sialate bonds in the employed volcano ash renders the volcano ash as an excellent pozzolanic material in the production of geopolymer composite.
In the preferred embodiment, the process of geopolymerizing is conducted by mixing the volcano ash with an alkali activator. The alkaline activator is a mixture of sodium silicate and an alkaline hydroxide, having a weight ratio in the range of 0.1 to 1.5: 1.5 to 3.0. The alkaline hydroxide is preferably sodium hydroxide. However, potassium hydroxide can also be used.
Further, the present invention discloses a method of producing a solid geopolymer composite comprised of reacting volcano ash with an alkaline activator to obtain a pozzolanic mixture and curing the mixture to obtain a solid composite. Preferably, the composition of volcano ash is presented in a range of 50 to 80% by weight of the
pozzolanic mixture. The mixture is cured at temperature preferably ranged from 150 to 1500 °C for 24 to 48 hours to obtain a solid composite for construction materials and/or friction materials. The method further comprises a step of drying the volcano mud at 60 to 110 °C to obtain volcano ash before reacting the volcano ash with the alkaline activator. The method further comprises a step of grinding and sieving the volcano ash to obtain a particle size in a range of 10 to 500 μηι. In particular, dried volcano mud is grinded into volcano ash of the preferred particle size by using a ball mill. Moreover, volcano ash with finer particle size is able to form a relatively more compact geopolymer composite for the fabrication of strong construction or friction material.
The following example is intended to further illustrate the invention, without my intent for the invention to be limited to the specific embodiments described therein.
