Characteristics of polyester polymer concrete using spherical aggregates from industrial by‐products

Abstract

Despite its excellent physical and mechanical properties, polymer concrete has not been widely used owing to its much higher unit price than conventional portland cement concrete. To ensure the economic efficiency of polymer concrete, it is utmost important to reduce the use of polymer binder, which occupies most of the production cost of polymer concrete. Based on the experimental investigations, replacing filler (calcium carbonate) and fine aggregate (river sand) with fly ash and rapid-cooled steel slag (RCSS), which are spherical materials obtainable from industrial by-products, was found to be effective for improving the strength characteristics and durability as well as the cost efficiency of polymer concrete. The product developed in this study successfully reduced the demand for polymer binder by 21.3% compared to the conventional product, which in turn saved the total material costs by 18.5%. Although the use of RCSS showed performance degradation at an elevated temperature condition, considering typical temperature ranges that actual concrete infrastructures experience, it is expected that the polymer concrete using fly ash and RCSS will provide high-level performances as construction and repair materials.

A Review on Epoxy and Polyester Based Polymer Concrete and Exploration of Polyfurfuryl Alcohol as Polymer Concrete

“…The mechanical properties of polymer concrete were investigated and it was reported to be more than 18 MPa. Hwang et al replaced filler (calcium carbonate) and fine aggregate (river sand) with fly ash and rapid-cooled steel slag (RCSS), which were obtained from industrial by-products to fabricate polyester polymer concrete [61]. They were found to be effective for improving the strength characteristics and durability as well as the cost efficiency of polymer concrete.…”

Modeling Properties of Composite Materials Based on Aqueous Mixtures Cement with the Introduction of the Organoborane Amine Complex As Compatibilizers

“…1 (строка 2-5), влияние концентрации добавки ОАК незначительно как на морозостойкость, так и на водонепроницаемость. Анализ литературных данных показывает [1][2][3][4][5][6], что наиболее широко используются как компоненты в смесях при получении КМ -аналогов бетона виниловые мономеры, такие как метилметакрилат, стирол, акрилонитрил, трет-бутилстирол, винилацетат. В клеевых композициях с ОАК чаще используют акриловые мономеры [17][18][19][20][21][22].…”

“…В строительстве и для дорожных покрытий особенно важными являются такие показатели композиционных материалов, как морозостойкость и водонепроницаемость при хорошей прочности. В этом направлении проводятся исследования и испытания новых материалов с включением мономер-полимерных составляющих [1][2][3][4][5][6]. Сочетание свойств бетонов и полимеров позволяет использовать их полезные характеристики, получать композиты, характеризующиеся высокой прочностью, долговечностью, высокой экологичностью и относительно низкой стоимостью.…”

Mechanical and Physical Properties of Polyester Polymer Concrete Using Recycled Aggregates from Concrete Sleepers

“…These PC disadvantages may be: expensive cost of resins used as binder agents, suitable precautions that should be applied to achieve a proper curing of PC, and need to use the high quality aggregates to produce PC, when it is compared with cement-based concrete. In order to reduce the high costs of competitive PC, together with recent environmental concern about wastes that end up in landfills, several researches [ 9 , 10 ] have been conducted to analyze the properties of PC made with industrial byproducts and cement-based concrete residues acting as aggregates.…”

“…Somewhat similar to the resin replacement, aggregates and microfillers have also been replaced by solid wastes from various industrial fields. Demolition materials from concrete and masonry wastes [ 15 ], residual glass from blasting operations [ 16 ], industry development and electrical production wastes such as fly ash or silica fume [ 17 ], crushed polymer concrete and mortar [ 18 ], rapid-cooled slag from the steel production process [ 10 ], or residual sands from foundry industries [ 19 , 20 ] have been studied as mineral aggregates and microfillers in the production of recycled polymer concrete (RPC). These investigations concluded that it is feasible to produce high quality RPC based on recycled solid wastes and performances of resultant materials could be improved by optimizing different variables of the mixtures.…”
