 of an earthquake-resistant building [XIV]. However, the PA addition in concrete also has some detrimental effects on its mechanical behavior and workability [XXIII]. The partial replacement of PA with NA in concrete always lowers its strength and modulus of elasticity [II, XXVI]. The concrete compressive strength along with its density reduces with an increase in the volumetric replacement of plastic with sand [XVII]. This phenomenon is attributed to the weak bond between the plastic and surrounding metrics and excess in the water-cement ratio due to the hyperbolic plastic surface instigating an increase in voids [XXVIII]. All failure modes in concrete are a consequence of tensile failure [IX] and improving the tensile strength is a method to lessen the reduction in compressive strength. The steel fibers are used in concrete to improve its mechanical performance and limit crack propagation. Researchers [VIII, III] have recorded an improvement in concrete tensile strength, flexural strength, and relaxation, with the partial replacement of coarse aggregates with steel fibers.
The main objective of this research work is to retain the compressive strength of concrete with the use of steel fiber while efficiently disposing of recycled plastic as fine aggregates in concrete. The test results discussed in this research are concrete compressive, tensile strength, and toughness index.

II. Experimental work
In this research, the recycled plastic granules (RPG) manufactured by recycling of polythene bags by a local plastic recycling factory were used (Fig. 1). The type 1 Portland cement used had normal consistency of 28%, initial setting time of 75 min, final setting time of 196 min (ASTM C187), the specific gravity of 3.01 (ASTM C77)., fineness of 92% (ASTM C184), and compressive strength of 23± 0.4 MPa (ASTM C109). The particle size distribution of fine and coarse aggregates used is shown in Fig.  2. Its fineness modulus was 2.8 (ASTM C136/C136M-14). The coarse aggregates with a maximum size of 0.75 inches were used. The hooked shape steel fibers of 65mm length and 0.5mm diameter were used (Fig. 1). The material properties evaluated using ASTM standards procedures are listed in Table 1.   Table  2. Twelve 6" * 12" concrete cylinder specimens per each configuration were prepared. In total ninety-six concrete cylinder specimens were tested. All the specimens were cured for 28 days before testing. Six out of twelve concrete cylinders per each configuration were subjected to a uniaxial compression test (ASTM C39 standard) and the remaining six to splitting tensile test (ASTM C496 standard).

III. Results and Discussion
The concrete cylinders were first cured for 28 days and then subjected to the uniaxial compression test with a Universal Testing Machine of 2000 kN capacity at a constant loading of 0.2 MPa/sec till specimen failure. Unbonded capping pads and retainers were used during the test as an alternative method to the Sulphur capping and grinding machine. The test results are depicted in Table 3 and Fig. 3. The concrete compressive strength decreased with an increase in pet content in the concrete mix, as reported in numerous research studies [XXIII, XIII, XXVIII]. The concrete specimen compressive strength decreased up to 38% with 20 vol% replacement of pet aggregates with sand (PC20), as compared to normal concrete (NC). This decrease in strength is attributed to the weak bond of pet particles with texture [XXII], apart from its lesser strength as compared to natural aggregates. The pet particle due to its inherent weak adhesion hinders the bond between cement paste and natural aggregates. This leads to the formation of weak interfacial transition zones [XXVI], through which the cracks initiate in specimens under lesser induced loading. The 1.5 wt% replacement of steel fibers with coarse aggregates limited the compressive strength deterioration to a great extent, credited to the good mechanical properties of steel fibers. The increase in compressive strength recorded in steel fiber concrete (SC) compared to normal concrete (NC) was 19%. However, the same improvement rate was not observed in the case of concrete with pet particles. The improvement in compressive strength of SPC10, SPC15, and SPC20 as compared to PC10, PC15 and PC20 was 7%, 12%, and 18%, respectively (% compared to control specimen NC). Therefore, the influence of steel fibers in concrete was higher in one with a higher vol% replacement of plastic granules with sand.  Table 3 & Fig. 4. The specimen split tensile strength decreased with the increase of recycled plastic granules (RPG) and increased with the induction of steel fibers. The 20 vol% replacement of RPG with sand reduced the overall strength by 45% in comparison to the control specimen. The decrease in tensile strength is much higher than in the case of compressive strength. This behavior is attributed to the weak interfacial bonding between the plastic aggregate and cement paste. The steel fibers replacement with coarse aggregates in all mixes improved their performance by almost 22%. According to Kang J. [XVI], "The ratio between the tensile and compressive strength can give information on the toughness behavior of the concrete specimen". Concrete of higher toughness displays its higher ratio [XXIV]. The tensile/compressive strength ratios are presented in Table 4. The RPG induction reduced the specimen toughness index whereas steel fiber addition in concrete mix regained/improved the specimen toughness index compared to the control specimen (NC).

IV. Conclusions
This study investigated the behavior of normal concrete modified by partial replacement of sand with recycled plastic granule and coarse aggregates with steel fibers as an additive. The recycled plastic granules were obtained from the recycling of polythene bags. For this purpose, compressive and split tensile tests were performed on specimens cured for 28 days. In total eight concrete mixes were used to examine the effect of these variables on concrete mechanical properties. Based on the test specimen experimental data evaluation, the following conclusions are made: • The partial replacement of sand with plastic granules in a normal concrete mixture reduces it's split tensile and compressive strength. The deterioration increase with an increase in vol% partial replacement and is owed to the poor adhesion between the cement paste and plastic granules. • The partial replacement of coarse aggregates with steel fibers yields positive results. It increases concrete compressive and tensile strength. • The effectiveness of partial replacement steel fiber with coarse aggregate in concrete in terms of strength, was not prominent in concrete with recycled plastic granule as compared to normal concrete. The weak interfacial bonding between the plastic aggregate and the surrounding matrix also affected its efficiency.Keeping pace with governance and compliance efforts requires a concerted effort, especially as a company scales and expands its offerings. As these products, services and platforms grow with velocity, they need continuous internal governance and compliance to help monitor and protect this accelerated growth.
To keep up, companies need to develop and implement an automated internal controls platform that’s scalable and can reduce the time required for teams to onboard required controls. An automated platform can also help reduce the number of tasks brought to operations and engineering teams, while continuously monitoring potential deviations from these required controls.
It’s often easier said than done, but when companies start applying automation to their compliance efforts, the benefits are endless. Adobe’s security compliance team has been working to automate our compliance platform and learned several lessons along the way. Here’s a bit of what we learned and how your team can implement automation into the compliance platform to help scale and meet security requirements, improving the overall posture of the organization.
Companies often have a hard time getting started with automation, so start by identifying what makes sense to automated first. Manual processes are often subject to human error and unnecessary overhead. When automating a process, outputs are held to a certain degree of efficiency and accuracy. For instance, product operations and engineering teams could spend hours ingesting requirements, but with the assistance of automation, companies can turn tasks around faster and are more digestible for teams.
At Adobe, our security compliance team automated our Common Controls Framework (CCF). The CCF serves as the foundational framework and backbone of Adobe’s companywide security compliance strategy, enabling our cloud products, services, platforms, and operations to achieve compliance with various security certifications, standards, and regulations. The automated platform now performs checks at regular intervals for continuous monitoring, alerting teams when potential risks arise and remediation of those as quickly as possible. Without this near-real time monitoring dashboard, the team would need to manually check for deviations in the requirements, but now the team gets automatically alerted quickly and seamlessly to help resolve issues as fast as possible.
Figuring out what to automate in a compliance process is just the first step. It’s essential to build a layered foundation that will improve operational efficiency and scalability of compliance at the company. For instance, we built automation into our platform consisting of four core layers: visualization, application, services and data. Together, they provide a one-stop view for compliance for the security organization.
Depending on a company’s current compliance strategy, it’s key to identify the core areas that need to scale the most, which can ensure minimal overhead. Real-time insights into the operating effectiveness of your controls and automated checks are essential.
