Manufacturing and Characterization Process of Polymer Concrete with Aggregate From Pumice Stone and Corn Husk Fiber as A Filler

Abstract

Research has been carried out regarding the manufacturing process of polymer concrete made from a mixture of pumice, sand (1: 1), corn husk fiber, epoxy and thinner resin. This research was conducted to determine the characterization of polymer concrete which will be tested physically and mechanically with the best composition mixture. The physical properties of polymer concrete which were analyzed namely density, porosity and water absorption; mechanical properties including impact strength, flexural strength and compressive strength, and polymer concrete microstructure analysis, namely SEM-EDX. The best results were obtained with a mixture of pumice, sand (1:1), corn husk fiber, epoxy and thinner resin. The result are as stated here, density: 1.84 g/cm3 with composition (49:49:2) 30 g epoxy resin, porosity : 0.44% with composition (50:50:0) 20 g epoxy resin, water absorption: 1.8% with composition (50:50:0) 25 g of epoxy resin. Whereas mechanical properties, on impact tests: 4.956 KJ/m2 with composition of (47:47:6) 25 g epoxy resin, flexural test: 22.22 MPa with composition of (45:45:0) 30 g epoxy resin, pressure test: 8.41 MPa with composition of (49:49:2) 30 g epoxy resin. XRD analysis shows that each of its constituents still have quartz, pumice, quartz, pumice-shaped hexagonal crystals, while corn husk fibers are amorphous crystals. The average sound absorption coefficient for the three samples (20%, 25%, and 30%) are 0.178; 0.152; and 0.234 at a frequency of 500 Hz - 6300 Hz, which meets the requirements of ISO 11654 and ASTM C.384.

Utilization Of Pahae Natural Zeolite In The Production Of Polymer Concrete Using Corn Shell Fiber And Polyurethane Resin As Adhesive

“…Compared to research (Maghfirah, 2019) on the manufacture and The highest flexural strength value of polymer concrete using pumice aggregate and corn husk fiber as filler is 22.22 MPa, indicating that this study has a good flexural strength value from previous research using corn husk fiber.…”

“…The chemical composition of the fiber determines the physical characteristics, thermal, and mechanical properties. In research (Maghfirah, 2019) which studies the Manufacturing Process and Characterization of Polymer Concrete with Aggregates from Pumice and Corn Husk Fiber as Filler demonstrates that the use of corn husk fiber improves the tensile and compressive strength of polymer concrete [5].…”
