Compressive and Impact Loads' Effects on The Behaviour of SIFCON Made of Plastic Waste Fibers

Abstract

SIFCON is a relatively new material and consists of slurry (cement or cement and sand), water, super plasticizers (water reducers) and fibers. In all previous research, steel fibers and other types of fibers were used, but in this study, waste plastic fibers Polyethylene Terephthalate (PET) created by cutting carbonated beverage bottles were used for the first time in the production of SIFCON.Three volume ratios (3%, 6% and 10%) of the total volume of the concrete mixture were used to add fibers in different volume ratios, and a reference concrete mixture was created for comparison. Tests of compressive strength, impact resistance, ultrasound transmission velocity check and other tests were performed on the constructed models. Compared with the reference concrete, according to the analysis of the results. The results showed an improvement in the compressive strength it increased by (18.5%), an increase in the impact resistance by (416.67%), and a decrease in the velocity of ultrasound by (19.42%).

Investigation of usability of recycled aggregate in SIFCON production

“…Similar studies are carried out in SIFCON production. Al-Hadithi and Al-Hadithi [17] examined the usability of waste plastic fibers in SIFCON production. Celikten and Canbaz [18] and Drdlova et al [19] investigated the properties of SIFCON composites produced using waste steel fibers obtained from waste automobile tires.…”

The Response of Ficus carica Seedlings to Foliar Spraying with α-Tocopherol and Organic Fertilization with SMC

“…Organic fertilization decrease the negative effects of environmental pollutants and the associated problems of chemical fertilization [10,11]. The shift towards using alternative fertilizers taken from natural organic sources instead of chemical fertilizers is one of the important and promising options as long as it leads to improving the nutritional status of the soil, moisture retention, and providing nutritious elements to plants, biofertilization can play a role in improving the leaves' content of elements, despite the superiority of chemical fertilization [12]. The study aimed to investigate the effect of organic fertilization with spent mushroom compost (SMC) and foliar spraying with α-Tocopherol on the growth and production of Black Diala fig variety.…”

Study on the structure and properties of non-water reacted polyurethane grouting materials

“…Statistics have shown that the leakage rate of construction projects in China exceeds 80%, and prolonged water leakage can lead to structural damage and compromise structural safety. Chemical grouting has become a common construction technique for repairing building leakage issues [1][2][3][4][5]. Among the various chemical grouting materials, polyurethane grouting material is the most widely applicable and extensively used.…”
