Ⅳ. Details & Results of R&D
In order to produce eco-friendly light-weight composite panel using industrial by-products such as blast furnace slag and paper ash, etc., we conducted an experiment to verify various properties of panel core and panel. The results of experiment were as follows:
1. Domestic and overseas panels for construction applications, which are available in the market, have a density ranging between 1.2 g/㎤ and 1.3 g/㎤. Panels, which are produced through curing method such as autoclave, etc., or produced by using lightweight aggregate such as EPS, etc., have a density of approximately 0.75 g/㎤.
The material used in this study was industrial by-product having the foaming properties and were considered to exhibit lightweight properties equivalent to those of autoclave and panels using EPS because many pores were formed inside binder when foaming performance was accelerated.
As strength was similar to that of cement paste of matrix produced experimentally by stimulating the industrial by-product, the targeted performance of lightweight matrix was set to 3 MPa or higher in compressive strength of panel core and to 0.8/㎤ or less in density.
2. The material selection experiment was conducted in such a way that the targeted performance of primary material for panel core could be met. The results showed that relatively higher strength and stable durability were chieved with NaOH or KOH when blast furnace slag was used as binder, and therefore blast furnace slag was found to be suitable for panel core application. In addition, paper ash was found to be a material that could help achieve lightweight properties of panel by reacting with materials containing OH^- and creating a large amount of gas as a result.
3. As pores can be created even with small amount of paper ash, the ratio of used materials was derived through experiment in order to meet the targeted performance of matrix. The results showed that the ratio of blast furnace slag and paper ash was 95:5 and that excellent performance was exhibited with alkaline activator containing 12.5% NaOH.
2. R&D process in the 2nd year
1) Selection of optimal blending to meet the targeted performance of dry binding system
Based on the results of this study, blast furnace slag and paper ash were used in lightweight matrix to meet the targeted properties of panel core while optimal ratio of blast furnace slag and paper ash was found to be 95:5. For the materials to reduce the use of alkali activator, it would be the most reasonable to slash the amount of NaOH through quantitative calculation of the amount that can lead to maximum generation of hydrogen gas in consideration of unreacted Si in paper ash, rather than using industrial by-products separately. Regarding the materials for improving density and strength, lightweight matrix with lightweight properties and high strength can be manufactured if 6-9% perlite, an inorganic material, is used, considering that density of perlite itself is in the range from 0.1 g/㎤ to 0.2 g/㎤ and therefore can reduce unit volume weight.
2) Selection of optimal blending of lightweight matrix and performance verification
Optimal blending of core was selected for application to dry lightweight wall. To validate performance based on optimal blending, we conducted experiments on water-resistance, thermal insulation, fire-resistance, and durability. The results suggested that all experiment items, such as water-resistance, thermal insulation, etc., met the standards satisfactorily.
3. R&D process in the 3rd year
1) Establishing design, manufacturing/production system for eco-friendly high-strength lightweight composite panel
We collected information and data related to curing conditions and regulations related to manufacture of existing eco-friendly high-strength lightweight composite panels. There were no separate regulations. For existing products, inorganic cementitious lightweight panels and cement composite panel were used mainly as cement. The production was made using inorganic fibrous materials, such as mineral wool, glass wool, ceramic wool, etc. In this study, we established the curing conditions while experiments were carried out based on type of surface materials and bonding method to derive optimal design plans for prototype.
2) Preparing the manual for evaluation of eco-friendly performance, manufacture/construction of flame-resistant/ thermal insulation composite panel manufacturing system
The products completed in this study were verified for dynamics, water-resistance, thermal insulation, and lightweight properties. To verify environmental performance of eco-friendly wall system, we measured the formaldehyde emission, deodorization rate, and far-infrared radiation.
