The wood plastic recycled composite are the reworked materials manufactured from waste , and have the possibility to be invateted by the microorganism. However, there is no data verified to the microorganism now. Then, fungi and the wood-rotting fungi were spraied, cultured in typical wood plastic recycled composite , and the level of the material degradation was examined in the present study. It has been understood that the material deterioration of internal doesn't occur though these microorganisms are grew on the material surface as a result.

In order to develop new eco-friendly building materials, authors tried making non-baked tile by densification of powders through carbonation and hydration after pressure forming. The studies on properties of casting calcium carbonate by same process have been already done by Arinaga. In this study, to make improvement of the casting calcium carbonate and apply the process to recycle by-product powder derived from used concrete, authors produced some kind of tile material experimentally and investigated the properties of them. In the result, authors presented the possible way to produce tile material by simple and energy saving process mainly using by-product powder which effective way of recycling is strongly hoped for.

In the previous report (part 1) we calculated solar reflection of the paint to examine an effect of the high reflectance paint and mechanism and reported that we measured a temperature change in the outdoors with various examination devices. In this report we installed all box specimens in the outdoor exposure site of the Building Research Institute and accumulated data during one year. We increased number of box specimens of other colors more than the previous report (part 1). We studied a correlation between the solar reflectance and the thermometry.

In the previous report (part 4) we calculated solar reflection of the paint to examine a correlation between the solar reflectance and the thermometry and reported that we measured a temperature change in the outdoors with the box specimens. The high reflectance paint is usually coated on a roof part, where deterioration of the paint is likely caused most rapidly and severely and, therefore, it is thought that the durability of the paint is related to the durability of the performance to block the heat. In this report, following the previous report(part3), we investigated about the durability of the heat blocking performance of the high reflectance paint measured by both the outside natural wethering test for two years and the accelerated weathering test for 3000 hours.

The rheological properties of cementitious materials are important to evaluate workability of cementitious materials. The properties of fresh cementitious materials conform the Bingham model which has a plastic viscosity and a yield stress. The purpose of this study is to evaluate the properties of fresh cement pastes and fresh cement mortars by a viscosity index and a yield stress index measured by the inclined blades rotational rheometer which was developed by authors in previous study. As a result, it was found that the mixing proportions such as water-cement ratio, sand-cement ratio influence rheological behavior of fresh cementitious materials, and the inclined blades rotational rheometer could evaluate the rheological bahaviour of cement mortar. Furthermore, it was cleared that the viscosity index and the yield stress index are related to the flow value measured by a table flow test according to JIS R 5201.

With regard to the stain-proof material by means of photocatalyst, the clear-type coating materials have been able to be used on the surface of general paints to provide the performance of stain-proof without damaging to the texture of finishing. However, there are little data of the durability with the combination of such finishings as general paint and the stain-proof materials. Therefore, the authors have tried to examine the durability of clear-type coating materials on the surface of general paints by means of accelerating test. This paper describes the results of the accelerating test and the examination of the evaluating method for the stain-proof performance.

Progressive deterioration of the paint film is attributed to resulting from the synergistic effects of ultraviolet rays and oxygen. The photo-oxidation reactions generate free radicals at a molecular junction of the paint film,which in turn generate other radicals from neighboring molecules and degenerate the wider area of the film. The one way to suppress the deterioration is converting the radicals into a stable material using an light stabilizer,for example,HALS.We report herein the results of the performance tests on a ceramic compound HALS-Hybrid resin paint that was constituted with the light stabilizer and ceramics stably incorporated into a resin.Compared with a thermoplastics type fluorine resin paint and a thermosetting urethane resin paint,our HALS-Hybrid resin paint demonstrates superior performance for outdoor construction materials.
