Brick debris that makes up the majority of construction waste has not received proper waste disposal in Indonesia. On the other hand, brick debris could be potentially reused as non-structural building materials to reduce its negative impact on the environment. This study aims to test the effectiveness of soundproofing on recycled brick debris. The soundproof test was carried out on brick debris in the form of fine and coarse grains. The simulation box is then used as a support for the brickwork material and then the box is exposed to a sound source with a certain level of noise that is considered disturbing human comfort. Noise level measurements are made in the outside and inside the box. These measurements are tabulated and then analyzed to see the success of the two aggregates in reducing noise. Basically, the brickwork material has succeeded in becoming a recycled building material that can absorb noise, although further research must be carried out to be able to state that this material is truly ready to be used as an alternative building material with good acoustic capabilities.

The number of destroyed cities in Iraq has increased significantly over the last five years. It presents a negative impact on the country's economy on the one hand and on the environment on the other. Reconstruction of these cities requires substantial capital to provide building materials needed for reconstruction and this leads to depletion of natural resources. This paper aims at finding an effective management method that contributes to the investment of the remnants of the components of destroyed buildings, including reinforcing steel, using the building information modelling (BIM) technique. The results showed that the amount of steel reinforcement that can be obtained from the destroyed buildings is enormous. Therefore, these quantities must be addressed through reusing or recycling. The sale of these quantities as recycling materials can provide a large income which can be added to the capital of the project.

Concrete is the most widely used building material and due to its use, water tightness is one of the factors essential for many constructions. Materials applied on concrete surface as secondary protection can have various forms. One of the material group with waterproofing ability, are materials on so called "crystalline technology base". As this material is cement-based its wide world production brings significant effect on environment. To bring on building materials market new materials should be considered its environmental friendlier production. One of the ways for this group of materials with crystalline abilities is replacing cement by other substituent, at best by secondary raw material. This would bring double advantage, lowering usage of cement and on the other hand use of already produced secondary raw material. This article deals with new developed materials based on "crystalline technology" with cement partly replaced by fly-ash substituent. At this article are presented results of new developed screed and coating modifications and its effectiveness on concrete waterproofing.

Annotation. At the present time, the issues of combating environmental pollution are especially acute in the world. At various scientific and public platforms, the sources of the negative impact on the environment and ways to restore the ecosystem are discussed. The purpose of this article is to consider one of the main sources of environmental pollution - construction waste. Having studied a number of works on this topic and summarizing the results obtained, the authors give a detailed description of environmentally hazardous construction waste. At the same time, the authors propose a solution to this problem, which consists in the recycling of waste, that is, in the reuse of unnecessary things for the purpose of subsequent use as raw materials, energy, materials and consumer products. The authors argue that recycling waste can be safe and profitable, with great returns. Thus, the recycling of environmentally hazardous, in this particular case, construction waste will contribute not only to solving environmental issues, but also to improve the economic situation of the state.

The alloy analysis of the building material of the copper hall from Taishan Mountain (TCH) is presented. First, the historical building structure of the TCH is investigated and introduced. Then the X-ray fluorescence (XRF) results are given. Analysis is done based on the units of building component. The results show that about one third of the components are made in brass, and two thirds are in bronze. Further, The XRF results are loaded into geographic information system (GIS) to analyze the relation between the building components and their materials. Most of the major structural components are made in bronze, or contains relative higher Sn. Finally, the reason why TCH use both bronze and brass as building materials is discussed.

 Many studies concerning innovation have been carried out on building contractors, but very few have studied innovation among the suppliers of building materials. In Sweden the cost of building materials is approximately 40% of the total building costs. Some products also need more handeling than others, therefore not only cost but also productivity is affectedby the suppliers of building materials. This article focuses on innovation among building material suppliers which is found to be low. The suppliers are compared to other lines of business to show the level of their innovation processes. The article is based upon slightly over 800 companies of various sizes. Important findings are:A smaller proportion of the Building Material suppliers than of the Other Manufacturers offer new products, invest in R&D, machinery and marketing the introduction of products.The Building Material Suppliers have a greater proportion of their sales from older products and have older equipment than Other Manufacturers.The Building Material Suppliers have poorer production processes and they are not as good at finding new ides as the Other ManufacturersThe study reveals barriers within the trade, where motivation seems to be of great importance.

The order and modalities of cross-member state redistribution as well as the net financial position of the member states are one of the most widely discussed aspects of European integration. The paper addresses selected issues in the current debate on the EU budget for the period 2007 to 2013 and introduces four scenarios. The first is identical to the European Commission's proposal; the second is based on reducing the budget to 1% of the EU's GNI, as proposed by the six net-payer countries, while maintaining the expenditure structure of the Commission's proposal. The next two scenarios represent radical reforms: one of them also features a '1% EU GNI'; however, the expenditures for providing 'EU-wide value-added' are left unchanged and it is envisaged that the requisite cuts will be made in the expenditures earmarked for cohesion. The other reform scenario is different from the former one in that the cohesion-related expenditures are left unchanged and the expenditures for providing 'EU-wide value-added' are reduced. After the comparison of the various scenarios, the allocation of transfers to the new member states in terms of the conditions prevailing in the different scenarios is analysed.

The automotive sector is one of the fastest growing sectors of economy. The increasing amount of cars both in Polish and world roads results in the immeasurable benefits associated with the goods and human transport. On the other hand, this phenomenon caused the contamination of the environment. During the fuel combustion in petrol or diesel engines, the harmful gases, for example CO2, NOx and SOx are emitted. Apart from the negative impact on the environment, the emission of the aforementioned gases results in the deterioration of human conditions, as well as, the development of civilization diseases. In order to minimalize the harmful influence of an automotive industry on the environment, new technologies which can reduce the consumption of fuel or limit the fumes emission are developed. The first part of paper presents new solutions in an automotive sector which influence on the decline of the negative impact of automobiles on the environment. Additionally, proposed solutions affect the development of a car industry, taking into consideration environmental aspects.

An investigation on the properties of Tenun Pahang fabric performances using alternative yarns was conducted. The studies were made in order to evaluate whether the Tenun Pahang fabric could be produced economically and at the same time maintain the fabric quality. Traditional Tenun Pahang fabric uses silk for both warp and weft. For this project, two alternative yarns were used which were bamboo and modal, which were a little lower in cost compared to silk. These yarns were woven with two variations, one with the yarns as weft only while maintaining the silk warp and the other with both warp and weft using the alternative yarns. Four (4) physical testings and three (3) mechanical testings conducted on the fabric samples. The fabric samples were evaluated including weight, thickness, thread density, crease recovery angle, stiffness and drapability. The results show that modal/silk and bamboo silk fabrics are comparable in terms of stiffness and drapability, hence they have the potential to replace 100% silk Tenun Pahang.

Payment in the Malaysian construction industry has generally been an issue of concern. Late and non-payment problem is endemic in construction and needs to be addressed. The aim of this study is to investigate the issues related to late and non-payment based on the building materials suppliers’ perspective. Questionnaires were distributed to suppliers of building materials in the Klang Valley. Findings from the study shows the main cause of late and non-payment is the paymaster’s poor financial management while the main effect of late and non-payment is problem with the cash flow.  The most recommended possible solution to cope with the issue is for the paymaster to conduct training on financial and cash flow management to the management team in the company.
