Use of recycled plastic in concrete: A review

This paper presents a rhetorical discussion on the subject of fiber-reinforced concrete, FRC. It is intended as an overview of the types of commercially available FRCs and how they work. It discusses commonly applied terminology and models of mechanical behavior that form a basis for understanding material performance without presenting mathematical details. Historical review is intended to help build a background for what is currently understood about FRC rather than as historical reporting. References from both early and contemporary authors are included as a means of tying the subject together along a time line.

Use of plastic waste as aggregate in cement mortar and concrete preparation: A review

An experimental research investigation of the fresh and hardened material properties of the fibrillated polypropylene fiber reinforced concrete is reported. Fiber lengths were 1/2 and 1/4 inch, and volume fractions were 0.1, 0.3, and 0.5%. Fiber effects on concrete properties were assessed. Properties studied were slump, inverted slump cone time, air content, compressive and flexural behaviors, impact resistance and rapid chloride permeability, and volume percent of permeable voids. An innovative method of characterizing the flexural behavior of fibrillated polypropylene fiber concrete was proposed. The new method was dependent on the post-peak flexural resistance of concrete. For impact resistance and flexural behavior, it was concluded that 1/4-inch-long fibers were more effective than 1/2-inch-long fibers for volumes of 0.3% or less, while 1/2-inch-long fibers were more effective for 0.5% volume.

Properties of polypropylene fiber reinforced concrete

The paper reports the results of an experimental study on the relative effectiveness of different types of steel fiber in concrete. A constant fiber volume fraction of 2 % was used throughout this investigation. The fresh fibrous mixes were characterized by their slump, inverted slump-cone time, and subjective workability, and the hardened materials by their compressive and flexural load-deformation relationships. The overall workability of fresh fibrous mixes was found to be largely independent of the fiber type, with crimped fibers producing only slightly higher slumps. Hooked fibers were found to be more effective than straight and crimped ones in enhancing the flexural and compressive behavior of concrete. Under flexural loads, crimped fibers were slightly less effective than straight ones in improving the strength and energy absorption of concrete.

Effect of curing procedures on properties of silica fume concrete

The properties of silica fume concrete was studied. Various properties of silica fume cocnrete, including slump, air-content, compressive strength, flexural strength, permeability, and permeable void volume were investigated, and the effect of the silica fume replacement ratio of cement is described. The effects of aggregate content and graduation, water-binder (cement plus silica fume), and superplasticizer dosage rate also are discussed. In this investigation, silica fume-binder ratios ranged from 0.00 to 0.40, water binder ratios from 0.41 to 0.47, aggregate binder ratios from 1.0 to 4.0, and superplasticizer binder ratios from 0.01 to 0.05.
