This research aims to study the application of kaolin with coconut meal plywood from corncobs and durian peel in concrete masonry unit wall for increasing effective heat protection and lightweight. The ratio of cement type 1: kaolin is equal to 1: 60 by weight. The kaolin is replaced by fiber include coconut meal fiber corn cob fiber durian peel fiber with 1.67% 3.33% and 5% by weight of kaolin. The kaolin concrete block mixed with fiber sample size is formed to 6.9 x 39 x 19 centimeter with the hydraulic compactor. The samples tested in physical and mechanical properties follow the TIS 58-2533 standard. Resulting their fibers can reduce the density thermal conductivity and compressive strength and increase the changing length and water absorption of kaolin concrete blocks. The kaolin concrete block without fiber has highest compressive strength followed by the kaolin concrete block mixed with corn cob fiber the kaolin concrete block mixed with coconut meal fiber and the kaolin concrete block mixed with durian peel fiber has lowest compressive strength respectively. However their fibers have possibility to be composite materials to reduce weight of kaolin concrete blocks.

This research aims to study the application of coconut meal corn cob and durian peel as wood-substituted biocomposites in medium density fiberboard. The fiber: urea formaldehyde glue: isocyanate glue with polymeric diphenymethane diisocyanate type (pMDI) ratio is equal to 1: 0.13: 0.003. The fibers are taken from coconut meal corn cob and durian peel that 7 ratios are used to all of fiber mixing. The fiberboard production use 130°C of temperature with 20 – 50 kg/sq.cm of compressive pressure with 8 minutes per piece of rate. Their fiberboards have 603 – 856 kg/m of density that was tested follow the TIS 876-2547 standard. Resulting the MM33 ratio (coconut meal fibers: corn cob fibers: durian peel fibers is equal to 0.33: 0.33: 0.33) and the CC50 ratio (coconut meal fibers: corn cob fibers: durian peel fibers is equal to 0.50: 0.25: 0.25) can pass the standard in physical properties and mechanical properties. Moreover their fiberboards have good thermal insulation.

งานวิจัยนี้มีวัตถุประสงค์เพื่อใช้ในงานวัดอัตราการเป็นสนิมของโครงสร้างคอนกรีตเสริมเหล็กโดยทั่วไป มักจะได้รับผลกระทบจากการเกิดสนิมของเหล็กเป็นส่วนมากเป็นผลให้กำลังของโครงสร้างคอนกรีตลดน้อยมีการพบการเสื่อมสภาพของโครงสร้างจากเหล็กเสริมเป็นสนิมอย่างแพร่หลายโดยเฉพาะโครงสร้างที่อยู่บริเวณชายฝั่งทะเล โดยสาเหตุสำคัญส่วนใหญ่ที่ทำให้เกิดสนิมมักเกิดจากคลอไรด์ซึมผ่านคอนกรีตเข้าไปถึงเหล็กเสริมและเมื่อคลอไรด์ซึมผ่านเข้าไปในคอนกรีตจนถึงระดับของเหล็กเสริม มีปริมาณมากเพียงพอก็จะทำลายฟิล์มที่ป้องกันที่ผิวเหล็กเสริม และทำให้โครงสร้างคอนกรีตเสริมเหล็กนั้นเกิดสนิมสะสมเพิ่มขึ้นเพียงพอที่จะทำให้เกิดหน่วยแรงและดันให้คอนกรีตเกิดความเสียหายเป็นผลทำให้กำลังของโครงสร้างลดน้อยลงจนไม่สามารถรับกำลังได้อีกและโครงสร้างจะเกิดการวิบัติในภายหลัง

This research has been object to development weaving machine design weave dye and Hyacinth paper and Instruct technology give community District Bangsai Amphur Province Ayutthaya which get instruct technology 20 persons. Research result to invention make up weaving machine. Fiber from Water Hyacinth dye Yarh Pa Per from water Hyacinth and product about 11 products. Evaluation from the participants were female aged 35-55. They were workers and earned 500-1000 Baht per month. Before training they had little knowledge. The training contents were correct and up-to-date. The trainers were excellent. The material equipment and documents were the most appropriate. The Participants had good attitude and the designing and developing of water Hyacinth’s was the most appropriate.
