It shows that tools using resin liquid as moistening agent by adding 4wt%~5wt% of the amount of bond and diamond to forming materials has the best performance in formability and bending strength of green and finished abrasive segment.
According to previous research, it can be concluded that under proper low temperature bond ratio and sintering parameters, diamond grinding wheels show good performance in processing specific materials.
Fig. 2 shows powder accumulation graph corresponding to different wetting agent in 3wt% used in forming materials.
So, using resin liquid as wetting agent in 4wt%~5wt% adding to forming materials can result in the best formability, green and finished abrasive segments bending strength.

Polyurethane can be prepared by simple addition reaction using polyol, isocyanate, foaming agent and chain extender as raw materials.
The existence of a large number of microporous bubbles makes polyurethane materials have light weight and better elasticity.

Soil Material Quality and Environmental Potential of Metallically Contaminated Soils J.
Material and Method The researched area of central Spiš (Krompachy, Rudňany, Slovinky and Poráč) is located in the Spiš region Fig. 1, which represents the territory of the 2nd environmental quality, i.e. a region with a slightly disturbed environment.
Mining of mineral resources together with the utility component also relocated large volumes of residual material, which was subsequently stored in the form of mining deposits, heaps and tailings ponds, which significantly disturbed the landscape structure and contaminated individual components of the environment.

A solution was found in the materials recyclability process.
RAP can be recycled and incorporated in different types of mixes like Hot Mix Asphalt (HMA), Warm Mix Asphalt (WMA) or Cold Mix Asphalt (CMA) or as aggregate in granular or stabilized base materials [4] together with “virgin” materials.
When a road pavement reaches the end of its service life, the materials can still maintain considerable value.
Austria does not confront the crisis as bad as Spain and they still have high quality ”virgin” materials.
Cost analysis suggests significant savings due to the use of RAP mixes, resulting from savings in materials and energy costs.

Introduction The improved GPS system for specification and verification of workpiece geometry is an engineering tool for product development and manufacturing, which is necessary as companies rapidly move ahead with new technologies, new manufacturing processes, new materials and technically advanced products in an environment of international outsourcing [1].
Concerning the expression of measurement uncertainties, the GUM [9] and ISO 14253-2 [10] offer methods to determinate their origins and of quantifying the latter (physical and chemical phenomena, mathematical modeling of the understood phenomena, interactions between materials and operating conditions).
