Abstract

Developments in modern times have grown rapidly, this can be seen from the rapid development. Along with the increasing scale of development in the world of construction, more and more concrete is needed effectively, practically, and in the future. The strength of concrete is strongly influenced by the quality of the materials, admixtures, the working process, and the curing of the concrete. Concrete with the addition of an accelerator has higher compressive strength, this is due to the accelerator reaction which can accelerate the binding process and the development of the initial compressive strength of the concrete. Concrete with direct immersion treatment has large compressive strength. There are several methods of treating concrete, including watering and high temperature. This study used a fixed accelerator proportion of 3 % of the weight of cement with a test time of 7 and 28 days. The treatment method used is open space, immersion, high temperature at temperatures of 25 ºC, 30 ºC, 35 ºC, 40 ºC and 45 ºC. From the results of the research, there are differences in characteristics between normal concrete and concrete with the addition of an accelerator. Concrete with a high-temperature treatment method at a temperature of 45 ºC produces the highest strong pressure. This is caused by the higher the treatment temperature, the higher the rate of hydration process that affects the compressive strength of the concrete.

Abstract

The increasing production of cement as a basic material for making concrete is due to the increasing demand for concrete throughout the world. Innovative materials are needed as a substitute for cement to reduce the greenhouse effect, fly ash is pozzolanic which in fact has the potential to replace Portland cement as the main ingredient of concrete, and duck eggshell flour has good prospects to be used as an additional precursor material for geopolymer concrete. This study aims to determine further variations of the proportion of duck egg shells, the mechanical properties of the concrete produced using duck egg shell ash with fly ash. This study used an experimental method with the percentage of duck egg shell ash at 0%, 5%, 10%, and 15% of the total use of cement. Using Na₂SiO₃ and NaOH as activator with a concentration of 14M. At the age of 7 and 28 days with room temperature treatment. This study resulted in duck egg shell ash being able to increase the compressive strength of concrete at the age of 28 days with the percentage of substitution up to 5% with a value of 59.26 MPa, in the porosity test the minimum value was at the age of 28 days at a percentage of 5% 0.403%, and the value of the modulus of elasticity. experienced an increase in value at a percentage of 5% with the result 36071.43 MPa. Duck egg shell ash with a proportion of 5% is the optimum substitution where the compressive strength, porosity and modulus of elasticity tests on geopolymer concrete have linear values.

Abstract

One of the problems in the construction field, especially concrete, is to reduce cracking due to the brittle nature of the concrete itself and increase the strength of the concrete. One of the ingredients to minimize cracks in concrete is the addition of fiber in the concrete mixture. Therefore, additional innovation is needed in the manufacture of concrete. So, this research was carried out by discussing the use of bendrat wire on the mechanical properties of geopolymer concrete. This study aims to determine the results of compressive strength, split tensile strength, and flexural strength with variations in the addition of 0%, 6%, 12%, and 18% were using a 2% superplasticizer with a concrete age of 28 days. The addition of bendrat wire from 0%, 6%, 12%, and 18% of the test results has increased. For compressive strength, respectively, 40.34 MP, 40.552 Mpa, 40.977 Mpa, and 41.189 MPa. For the splitting tensile strength result, which is 2.07 MPa;, 2.123 MPa, 2.176 MPa, and 2.229 MPa. For flexural strength, 4.05 Mpa, 4.09 Mpa, 4.16 Mpa, and 4.25 MPa.
Evaluasi Tingkat Kerusakan dan Perencanaan Estimasi Biaya Perbaikan Bangunan Guna Sustainability Gedung di Universitas Jember (Studi Kasus : Gedung 1 Fakultas Keguruan dan Ilmu Pendidikan (FKIP)) Nanda, Wisnu Eka; Ratnaningsih, Anik; Nurtanto, Dwi

Abstract

Sustainability bangunan gedung sangat dipengaruhi oleh periode penggunaan atau keberfungsian dari bangunan. Agar supaya periode penggunaan sesuai dengan perencanaan, maka pemeliharaan bangunan perlu dilakukan secara berkala terhadap kerusakan dari komponen-komponen bangunan gedung sehingga dapat menjaga tingkat kenyamanan dari para pengguna bangunan gedung tersebut. Tujuan dari penelitian ini adalah untuk mendapatkan indeks kondisi bangunan berdasarkan tingkat kerusakannya, skala prioritas perbaikan, serta estimasi angaran biaya perbaikan bangunan. Evaluasi dilakukan pada Gedung 1 FKIP Universitas Jember. Metode untuk mendapatkan Indeks Kondisi Bangunan dilakukan melalui survey lapangan dengan cara pembobotan komponen dan sub-komponen bangunan menggunakan Analytical Hierarchy Process (AHP). Hasil analisis didapatkan Indeks Kondisi Bangunan Gedung 1 FKIP Universitas Jember sebesar 87,85% yang berarti gedung masih berada dalam kondisi sangat baik, dan tingkat kerusakan sebesar 12,15% yang membutuhkan perbaikan. Estimasi biaya perbaikan didapatkan berdasarkan volume kerusakan masing-masing komponen bangunan gedung dengan nilai sebesar Rp. 48.652.000,00 dengan skala prioritas perbaikan tertinggi pada komponen dinding sebesar 25,9%.
