Abstract
As of today, the development of energy efficient and recycling technologies seems to be urgent. This article considers the problem of recycling of wastes in roofing industry, which is a serious environmental contamination source and creates a significant fire hazard. We have made an attempt to create a new drainage material from roofing waste. This material has the appearance of fibrous board, which is made of trimmings of bitumen-impregnated roofing roll materials thermally bonded in contact points. The technological scheme of the producing of the material was developed. The material was tested to determine its physical and mechanical properties (tensile and compressive strength, water permeability and porosity) and to optimize its technological parameters. According to the results of the experiment it was founded that the material has sufficient physical and mechanical properties, meets the technical requirements for drainage materials and can be recommended for use in underground construction.
Highlights
During the construction and operation of residential buildings and industrial structures, underflooding of basements is often observed
More often drainage boards made of filtration materials are used as wall drainage: filtration concrete, filtration expanded polystyrene, etc. (Figure 1a)
We have made an attempt to develop a drainage board material, formed by the thermal bonding of trimmings of roofing waste products according to the following technological scheme
Summary
During the construction and operation of residential buildings and industrial structures, underflooding of basements is often observed. Filtration concrete has an open porous structure, due to the fact that the binder, enveloping the grains of aggregates, leaves space between them, providing filtration of water. Such boards have some drawbacks: a large mass, brittleness, laboriousness during installation. Plastic waterproofing membranes have some advantages over drainage boards, but they are quite rigid, which makes it difficult to perform overlap joints, because it requires using special mastics to better bond joints They have a high cost [9,10,11,12]. Around each plant that produces rolled roofing materials, huge mountains of waste are formed, which pollute the environment and create a significant fire hazard
