Manufacture and Characterization of Polymer Concrete with Pumice Aggregate and Banana Stem Fiber and Styrofoam Waste as a Filler

Introduction

The construction industry has been facing significant challenges in recent years, including the need for sustainable and environmentally friendly materials. One potential solution is the use of polymer concrete, a composite material made from a mixture of cement, aggregate, and polymer. In this study, we explored the manufacture and characterization of polymer concrete using pumice aggregate, banana stem fiber, and styrofoam waste as a filler. The main purpose of this study was to examine the effect of reducing the number of pumice aggregates and the addition of banana stem fibers with various compositions.

Methodology and Composition

The composition under study includes the ratio of sand, pumice, and banana stem fiber with the following ratio: (25: 35: 0), (25: 33: 2), (25: 31: 4), (25: 29: 6), and (25: 27: 8) in units of weight percentage, using 40% epoxy resin. In addition, there are also other compositions namely (25: 25: 0), (25: 23: 2), (25: 21: 4), (25: 19: 6), and (25: 17: 8) Styrofoam solution 10% and 40% epoxy resin as a matrix. The hotpress method was used to manufacture the polymer concrete at 90 ºC for 20 minutes.

Testing Parameters

The researchers conducted a series of tests that include physical tests (density, porosity, and water absorption), mechanical tests (violence, flexural strength, and compressive strength), as well as microstructural analysis and elemental content using SEM-EDX techniques. The test results show that the best physical properties of this polymer concrete have a density of 1,400 g/cm³, porosity of 0.25%, and water absorption of 0.204%. In testing mechanical properties, the resulting polymer concrete shows optimal violence of 56,0166 HVN, flexural strength reaches 26,830 MPa, and compressive strength of 34,082 MPa.

Analysis and Implications

The use of pumice and banana stem fiber in this polymer concrete mixture brings positive implications in reducing environmental impacts, considering the two ingredients are more environmentally friendly resources than conventional materials. In addition, the addition of styrofoam waste as a filler has the potential to reduce plastic waste, while increasing the physical and mechanical properties of the concrete. The success of this study shows that alternative aggregate-based polymer concrete can be a decent solution in construction applications.

Characterization of Polymer Concrete

The characterization of polymer concrete was carried out using various techniques, including SEM-EDX, XRD, and FTIR. The results show that the polymer concrete has a uniform distribution of epoxy resin and a good bonding between the pumice aggregate and banana stem fiber. The SEM-EDX analysis reveals the presence of pores formed and the distribution of epoxy that are evenly distributed in polymer concrete samples.

Mechanical Properties of Polymer Concrete

The mechanical properties of polymer concrete were evaluated using various tests, including compressive strength, flexural strength, and impact resistance. The results show that the polymer concrete has a good compressive strength of 34,082 MPa, flexural strength of 26,830 MPa, and impact resistance of 56,0166 HVN.

Physical Properties of Polymer Concrete

The physical properties of polymer concrete were evaluated using various tests, including density, porosity, and water absorption. The results show that the polymer concrete has a good density of 1,400 g/cm³, porosity of 0.25%, and water absorption of 0.204%.
