Abstract

Abstract: In construction projects in the field during the construction process and after construction, we oftenencounter various problems, one of which is damage to the concrete which can result in weakening of thestructure. We can find this damage in concrete structural elements such as columns, beams, plates, concrete walls. Therefore, it is necessary to prevent this damage by conducting case studies regarding the causes of damage to concrete so that the causes of damage can be identified and minimized. This research was carried out in collaboration with the applicator and observations in the field to obtain relevant data. This data will be analyzed for the causes of damage by comparing it with experts' theories, then results will be obtained as to the general causes of concrete damage and suggestions for prevention that can be taken. Based on the research results, it was found that the factors that cause concrete damage are casting height,formwork removal errors, ironing errors, vibrators, curing, casting dilatation, design failure, and additional loads. Incorrect use of vibrators turns out to be the most dominant factor causing damage to concrete. Keywords: concrete; damage trigger Abstrak Pada proyek konstruksi di lapangan pada saat proses konstruksi dan pasca dalam bidang konstruksi sering kita jumpai berbagai permasalahan, salah satunya adalah kerusakan beton yang dapat mengakibatkanmelemahnya struktur. Kerusakan ini dapat kita temukan pada elemen struktur beton seperti kolom, balok,pelat, dinding beton. Oleh karena itu, perlu dilakukan pencegahan kerusakan tersebut dengan melakukanstudi kasus mengenai penyebab kerusakan beton sehingga penyebab kerusakan dapat diidentifikasi dandiminimalkan. Penelitian ini dilakukan secara kolaborasi aplikator dan observasi di lapangan untuk memperoleh data yang relevan. Data Penyebab kerusakan akan dianalisis dengan membandingkannyadengan teori para ahli, kemudian memperoleh hasil penyebab umum kerusakan konkrit dan memberikansaran pencegahannya dapat dilakukan. Berdasarkan hasil penelitian diketahui bahwa faktor penyebab kerusakan beton adalah ketinggian jatuhpengecoran, kesalahan pelepasan bekisting, kesalahan pembesian, vibrator, pengawetan, dilatasi pengecoran, kegagalan desain, dan beban tambahan. Ternyata kesalahan menggunakan vibrator merupakan faktor yang paling dominan menyebabkan kerusakan pada beton. Kata kunci: beton; pemicu kerusakan

Abstract

ABSTRACTFiber concrete is a composite concrete consisting of ordinary concrete and fiber materials. The purposeof adding fiber is to increase the tensile strength of concrete, so that concrete is resistant to tensile forces due toweather, climate and temperature. In this research, the manufacture of mortar with banner fiber added materialwas carried out to determine the compressive strength, flexural strength, and tensile strength of fibrous mortar.The method used is an experimental method by adding synthetic fiber Polyvinyl Chloride in banner waste as anadded ingredient in the manufacture of fibrous mortar. The variation of banner waste fiber used is 0%, 1%, 2%and 3%. The fiber length used is 10 x 1 mm. From the test results, it was found that the compressive strengthand flexural strength of the mortar decreased and the tensile strength of the mortar increased at a percentage of1.51% by 1.66 MPa. The average yield of axial tensile strength at 1% is 1.70 MPa, 2% is 1.49 MPa, 3% is 1.42MPa which is higher than the average axial tensile strength at 0% mortar of 1. 35%.Keywords: banner fiber waste; fiber concrete; fiber mortar. ABSTRAK Beton berserat merupakan beton komposit yang terdiri dari beton biasa dan bahan serat. Tujuanditambahkan serat untuk meningkatkan kekuatan tarik beton, sehingga beton tahan terhadap gaya tarik akibatdari cuaca, iklim dan temperatur. Dalam penelitian ini dilakukan pembuatan mortar dengan bahan tambah seratbanner untuk mengetahui kuat tekan, kuat lentur, kuat tarik pada mortar berserat. Metode yang dilakukan adalahmetode eksperimen dengan menambahkan serat sintesis Polyvinil Chlorida yang ada pada limbah bannersebagai bahan tambah dalam pembuatan mortar berserat. Variasi serat limbah banner yang digunakan adalah0%, 1%, 2% dan 3%. Panjang serat yang digunakan berukuran 10 x 1 mm. Dari hasil pengujian didapatkan kuattekan dan kuat lentur mortar menurun dan kuat tarik mortar meningkat pada persentase 1,51% sebesar 1,66MPa. Hasil rata-rata kuat tarik aksial pada persentase 1% sebesar 1,70 MPa, 2% sebesar 1,49 MPa, 3% sebesar1,42 MPa yang lebih tinggi dibandingkan dengan rata-rata kuat tarik aksial pada mortar 0% sebesar 1,35%.Kata kunci: beton berserat, mortar berserat; serat limbah banner.

Abstract

Abstract This paper briefly introduces the recycling and regeneration preparation of waste concrete, as well as the crushing and screening process of waste concrete blocks. The properties of crushed aggregate and the physical and mechanical properties of recycled concrete were analyzed, and the research status of compressive strength and splitting tensile strength of waste concrete at home and abroad was summarized and analyzed. Factors such as water-glue ratio, water absorption, apparent density of recycled coarse aggregate, state of recycled coarse aggregate and strength of virgin concrete will affect the strength of recycled aggregate concrete. This paper also summarizes the relationship between the splitting tensile strength of recycled aggregate concrete and the compressive strength of the cube. Keywords: Recycled aggregate concrete; compressive strength; splitting tensile strength. Abstrak Makalah ini secara singkat memperkenalkan persiapan daur ulang dan regenerasi limbah beton, serta proses penghancuran dan penyaringan blok beton limbah. Sifat agregat hancur dan sifat fisik dan mekanik beton daur ulang dianalisis, dan status penelitian kuat tekan dan kuat tarik belah beton limbah di dalam dan luar negeri dirangkum dan dianalisis. Faktor-faktor seperti perbandingan water-glue, daya serap air, berat jenis agregat kasar daur ulang, keadaan agregat kasar daur ulang dan kekuatan beton perawan akan mempengaruhi kekuatan beton agregat daur ulang. Tulisan ini juga merangkum hubungan antara kuat tarik belah beton agregat daur ulang dengan kuat tekan kubus. Kata kunci: Beton agregat daur ulang; kekuatan tekan; kekuatan tarik belah.
