Rubber concrete improved properties

However, one big implication of rubber in structural applications refers to the incorporation of waste tire rubber in concrete [156-161] this is also one of the most encountered applications of recycled rubber from tires to obtain building materials with improved properties, including high resistance to freeze-thaw, acid attack, and chloride ion penetration high strength and high resistance to sulfate, acid, and chloride environments [156],... 

MW 0/1mud Mica. Wei ground mica is used because of its unique properties, i.e.. luster, slip and sheen, and high aspect ratio. It is used in wallpaper and coated paper, nacreous pigments, as a coating for rubber, in ouidoor house paint, and in aluminum paints. Mica is used in all types of scalers for porous surfaces, such as vvallboard masonry, and concrete blocks, to reduce penetration and improve holdout and as a filler in plasties to improve its electrical and thermal resistance and its insulating qualities. See also Sealants. 

As mentioned earlier, the addition of rubber particles typically leads to the degradation of mechanical properties of the concrete due to a poor adhesion. However, it was shown that the adhesion of GRT of an average size of 120 ttm to cement was improved by applying surface plasma treatment to... 

In another study using crumb rubber (size 0/0.7 mm and quantity 15% and 18%), it was also found that the characteristic and rheological properties of the bitumen improved. However, the storage stability requirement of the rubberised modified bitumen (RmB) was not satisfied. When wet and dry processes were compared on extracted RmB from an asphalt concrete mixture (AC 8 mm), it was found that the effect of crumb rubber was more profound when the wet process was used (Lukac and Valant 2011). 

The term Filler indicates something used to fill gaps mainly fillers are particles added to material (plastics, composite material and concrete) to improve some properties of the mixture material. Worldwide more than 53 million tons of fillers are used every year in different application areas, such as paper, plastics, rubber, paints, coatings, adhesives and sealants. As such, fillers, produced by huge nmnber of companies, rank among the world s major raw materials and are a major constituent in a variety of goods for daily consmner needs. 

Fiber-reinforced plastics are the most successful composite materials. In spite of the poor load-bearing ability of polymeric materials, excellent mechanical properties are achieved by using fiber architectures of glass and carbon hbers in a manner similar to the reinforcement of concrete with steel rods and frames. For example, toughened polymeric materials with dispersed rubber particles in a polymer matrix exhibit high fracture energy. In composite materials, introduction of secondary materials into the matrix can improve the mechanical properties considerably. 

Thanks to all these properties, the dolocarbonate seems promising for different applications, first of all for all the applications of traditional low density mineral fillers. This material could for instance be used as a component in thermal insulating materials like panels or foams, as a filler in mortars or plasters or concretes to decrease their thermal conductivity, as a filler in polymer or rubber compositions to improve their fire and/or mechanical properties, as a filler in paints, papers, cosmetic compositions, as a rheology modifier (viscosifying agent) in mineral slurries, glues, bitumen or asphalts, polymer compositions, as an ad- or absorbant in different applications such as water or flue gas treatment or even in the field of catalysis, as e.g. a catalyst support, or as a carrier for perfumes, aromas, active substances, medicines...
