Fresh, Mechanical Properties and Impact Resistance Behavior of Eco-Friend Self-Compacted Concrete

Abstract

In this work, waste glass powder from broken windows and plastic fibers from waste polyethylene terephthalate bottles are utilized to produce an economical self-compact concrete. Fresh properties (slump flow diameter, slump Flow T50, V. Funnel, L-Box), mechanical properties (Compressive strength and Flexural strength) and impact resistance of self-compact concrete are investigated. 15% waste glass powder as a partial replacement of cement with five percentages of polyethylene terephthalate plastic waste were adopted: 0% (reference), 0.5%, 0.75%, 1%, 1.25% and 1.5% by volume. It seems that the flow ability of self-compact concrete decreases with the increasing of the amount of plastic fibers. The compressive strength was increased slightly with plastic fiber content up to (0.75%), about 4.6% For more than (0.75%) plastic fiber. The compressive strength began to decrease about 15.2%. The results showed an improvement in flexural strength and an impact on the resistance in all tested specimens' content of the plastic fibers, especially at (1.5%) fibers.

The Feasibility of Using Micro Silica Sand Powder as Partial Replacement of Cement in Production of Roller Compacted Concrete

“…However, for M4 mix with 20% of SSP the Max. γ dry has decreased while the OMC has increased, because of the increase in water content, and thus the w/cms ratio results in an increase of paste volume and porosity so, density will be decreased [29,32,33]. These results are in line with [31,32].…”

“…Figure 6 presents the f'c of control mix (M1), which has satisfied the specification requirement [50], in addition to the high quality (good density and lower voids) of the produced concrete as shown in Figures 7, 8 and 9. These results had obtained, although M-sand had used rather than conventional river sand [29,13,28,26,36]. The f'c results for all cubes that had tested in parallel // (as it had compacted) direction are higher than that of perpendicular (normal ꓕ) direction.…”

“…The density of RCC decreases when using crushed aggregate. Besides, Partial cement replacement by mineral admixture causes a reduction in f'c at an early age [29]. For the modified compaction test, the maximum density increases with increasing water content, which would continue to fill the voids of a material mass then the material would be very loose to withstand the compaction load [30,31,32,33].…”

Mechanical Properties of Sustainable Fiber-Reinforced Lightweight Aggregate Concret

“…Very few studies are found on the properties of chopped carbon fiber reinforced structural LWAC, including local pumice (Coarse and fine) as lightweight. Sheelan et al [8] explain the uses of chopped carbon fibers with different volume fractions (0.5%, 1%, 1,5%2%, and 2.5%) lengths of 6 mm to enhance the tensile strength of Porcelanite lightweight aggregate concrete. High-range water superplasticizers and silica fumes were used in the investigation.…”

Effect of adding depolymerized polyethylene terephthalate waste on the acoustic insulation and hardness properties of Iraqi cement mortar

“…Many studies have been investigated the qualities of the hardness and fresh concrete including plastic materials [8][9][10][11][12]. Sheelan M. Hama, et al, [13] studied using waste water bottles made from polyethylene terephthalate (PET) as fiber form, manufacturing by self-compact concrete. PET fiber was used with five different content of (0.5%, 0.75%, 1%, 1.25% and 1.5%) by cement weight.…”
