Abstract

Modern materials are those materials that have less impact on the environment in their extraction, processing, use, recycling, and disposal. In addition, they must not be harmful to our health and should contribute to a better climate on the premises. Overall the environmental impact of materials depends on many factors and they may differ in different places around the world.

In their essence, the modern materials and manufacturing processes are found in many places worldwide and are used for the construction of various structures. In view of the popular environmental movement and the idea of an environmentally friendly lifestyle, more and more entrepreneurs decide to use modern materials in the construction of their buildings (Berge, 2008).

It is precisely for this reason that the actuality of this research is unmistakable, and its purpose and aims are the following:

A literature review of the most commonly used modern materials;

Ways of constructing a modern building out of modern materials;

Recommendations and conclusions for their better usage;

The research is built upon two main chapters. Chapter one introduces the modern materials and outlines the researcher’s motivation to carry out this particular study and the significance of the research. It poses several questions and concluding by outlining the aims of the research and providing an overview of the organization of the research. Chapter two uses a number of sources as evidence, as well as deep understanding of the different perspectives of the on-site construction.

CHAPTER ONE. MODERN MATERIALS IN THE CONSTRUCTION TECHNOLOGY

Modern materials can be used in various ways in the construction or they can replace old items during the repair. In this research, we talk about modern alternatives associated with the on-site construction.

1.1. Wooden material

Wood as a renewable resource has been used for centuries for construction and is once again to the attention of homeowners, architects, and engineers. The tree is easy to handle, can carry heavy loads, visually attractive is and can contribute to a pleasant indoor climate.

Wood is a carbon neutral product and its impact on the environment is determined by the energy used in forestry, processing, and transport. If treated properly, the wood can be very durable material and can also be used after its use as a building material. The wood produces very little waste, and only specially treated wood may not be reused or incinerated and should be deferred (Lyons, 2007).

The wood does not need chemical treatment if the structure is properly made and in compliance with certain rules for working with wood. Wood, treated with aggressive chemicals, should only be used if you are unable to use alternative building materials and should not be used inside the buildings. There are several types of wood products used in construction. Among them are: hardwood, plywood, laminated wood, chipboard, and OSB. The wooden boards that consist of multiple layers of wood or wood chips contain adhesives.

There are several types of adhesives used in the woodworking industry and most of them are based on formaldehyde. However, only some of these glues emit formaldehyde after gluing on the wooden board, especially urea-formaldehyde resins. Exposure to formaldehyde of wood-based products depends on the type of material used, how it was taped and how many items were found inside the building (Lyons, 2007).

Covered and sealed boards can reduce emissions, but their surface should not be hurting in the aftermath, eg. through drilling. In addition, wood products, which do not emit formaldehyde, have an eco-label in some countries.

1.2 Isolation

When it comes to isolation, there are several options for using more or less modern friendly materials. These environmentally friendly materials are an alternative to conventional, especially synthetic materials.

Despite the fact that the synthetic materials have good insulating properties, there are some concerns about their usage. First, the energy for the production of these substances is huge, typically more than twice the energy needed to produce environmentally friendly alternatives. Second, some of these products, such as polystyrene or polyurethane (PUR) are obtained from petroleum or natural gas that is limited resources (Lyons, 2007).

Third, some materials are produced based on the products which are not safe. For the production of a PUR foam, for example, are being used harmful isocyanates. And last but not least, synthetic materials have the same fire as many environmentally friendly materials but have a significant disadvantage in case of fire emits toxic fumes and thick smoke (Eyerer,Reinhardt, Hans-Wolf, 2000).

1.3 Mineral wool isolation

The most commonly used material is mineral wool (rock or glass wool). The mineral wool is made from natural resources, but because it is produced at a temperature above 1400 ° C, it is energy intensive. To save resources, up to 60% of the basic materials may be old glasses or production residues. Furthermore, it contains organic resins for shape retention and hydrophobic agents. Mineral wool can be partially recycled and composted. It may release small synthetic mineral fibers at work. These fibers may cause mechanical irritation of the skin. Mineral wool, which is sold in Europe nowadays contains biodegradable fibers and is generally defined as non-cancerous. However, there remain some doubts and preventive safety measures are recommended (gloves, etc.) (Eyerer,Reinhardt, Hans-Wolf, 2000).

Due to the very good insulating properties of the wool, we have relatively sustainable choices, especially if part of the product is obtained from recycled materials. Due to the high initial energy to produce it has a negative effect on the environment (Lyons, 2007).

1.4 Cellulose insulation

Cellulose insulation typically comes in two forms: as fibers or lanes. Both can be used for insulation of wood frame structures and roofs. The fibers are suitable for filling small cavities into which other less flexible insulation systems cannot reach.
