Building materials must meet several requirements so that they can be used in a given application. These requirements are determined from the measurement of physical properties, depending on the nature of the components. This paper presents a set of mathematical processes and analyses to be carried out for new materials development according to the theory of dispersed or polydispersive systems, including a set of proposed steps to characterize such materials as the criteria for the study. Studies are considered at the microscopic level from the interaction of the elements and the macroscopic level from properties for emulsion cases, including viscosity.

This article engages in a survey on the countryside’s building materials in Zhejiang province, and indicates problems in the new countryside construction during the early 1990s to 2005: on one side, rarely few new materials for energy-conservation is being used; on the other side, traditional materials of local characteristics are abandoned. Therefore, this article indicates a range of materials which make improvement or innovation on traditional ones for the characteristic of Zhejiang rural areas. Then comparison is made between clay brick and these ecological materials. As a result, this guides villagers to improve the indoor thermal comfort and to promote rural economic development without large investment.

Experimental Charge Density

The ongoing increase in the number of experimental charge-density studies can be related to both the technological advancements and the wide applicability of the method. Regarding materials science, the understanding of bonding features and their relation to the physical properties of materials can not only provide means to optimize such properties, but also to predict and design new materials with the desired ones. In this tutorial, we describe the steps for a charge-density analysis, emphasizing the most relevant features and briefly discussing the applications of the method.

Color Attribute

The sensory experience of visual perception and quantification of physical properties of colors are combined in this paper, and with the colors commonly used in buildings materials in the cold region of China as an example, based on the visual perception principle, the changes in such color attributes of buildings as chromaticness, blackness and hue in vision in different weather and observation distance conditions are analyzed. The result shows that the stimulus degree of chromaticness and blackness decreases with the increase in observation distance, directly related to weather changes, while hue basically remains unchanged. Keywords: cold regional, color attribute, weather factors

Rock Wool

Production of building materials is mostly energy consuming. In the sphere of insulation materials we mostly see rock wool based materials or foam-plastic materials whose production process is demanding from material aspect and raw materials aspect as well. At present the demand for thermal insulation materials has been growing globally. The thermal insulation materials form integral part of all constructions in civil engineering. The materials mainly fulfill the thermal insulating functions and also the sound-insulating one. The majority of thermal insulation materials are able to fulfill both of the functions simultaneously. The paper describes questions of thermal insulation materials development with good sound properties based on natural fibres that represent a quickly renewable source of raw materials coming from agriculture. The main advantage of the materials are mainly the local availability and simple renewability of the raw materials. In addition an easy recycling of the materials after their service life end in the building construction and last but not least also the connection of human friendly properties of organic materials with advanced product manufacture qualities of modern insulation materials.

This paper provides an introduction to shipboard signage design, construction, and installation. It is intended to assist the naval architect and marine engineer in the design of signs for shipboard use, help the shipyard in its initial procurement and installation of shipboard signage, help the ship's crew determine what additional signs are needed during the life cycle of the vessel, and aid in the sign replacement process. There are a number of standards and specifications, both commercial and military, that deal with signage but few are in complete agreement. Research into these standards has resulted in the development of a user-friendly shipboard signage guide, applicable to both military and commercial vessels, which is paraphrased in this paper. Guidance is provided for the most commonly used shipboard signage applications and includes the use of new materials which are less expensive, lighter weight, and more visible even in low or no light conditions. By using this guide, effective signs which offer reduced cost (material and installation) and weight, with improved readability, clarity, and meaning will result. Specific areas addressed include signage types, layout, wording, symbology, physical properties, installation, and cost.
