Abstract

AbstractIn the current construction development, concrete is the main material used because of its advantages in strength and durability. One of the innovations in the use of concrete is flow concrete, which allows use without compactors and has optimal viscosity. The use of glass powder as a partial substitution of cement is an attractive alternative because of its potential in improving concrete properties. Glass powder has a fairly large silica (SiO2) content of 75%. Silica has a strong relationship with the compressive strength of concrete. Proper silica in concrete mix can increase the compressive strength of concrete. This study aims to determine the effect of glass powder with variations of 0%, 6%, 8%, 10%, 12% on the compressive strength of flow concrete with a proportion of superplasticizer 1.5%. Compressive strength testing is carried out when concrete reaches the age of 7, 21, 28 days using cylindrical specimens measuring 15 × 30 cm. From the test results, the highest compressive strength value was obtained at 28 days concrete age, namely in an 8% glass powder mixture of 25.61 Mpa and the lowest compressive strength value in a 12% glass powder mixture of 21.26 Mpa. Based on the results of this study, it can be concluded that glass powder as a partial substitution of cement can increase the compressive strength of flow concrete with an optimal glass powder mixture of 8%. Keywords— Flowing Concrete, Glass Powder, Compressive Strength

Abstract

In the construction sector, there is the term BIM, which stands for Building Information Modeling. BIM is a system that forms a process in conveying information or digital references for more accurate physical and functional characteristics about a construction which includes AEC (Architecture, Engineering, and Construction). BIM includes sharing information related to a project/building, from the beginning of planning (pre-construction), implementation (construction), maintenance (maintenance) to demolition (demolition) of the building. The dimensional approach to BIM is known to have advantages, in contrast to conventional applications which are generally still limited to the 3D stage. It is known that BIM can be utilized up to the concepts of 4D (scheduling), 5D (estimating), 6D (sustainability), and 7D (facility management applications) approaches.In this final assignment proposal, we will discuss the use of the Building Information Modeling (BIM) concept by creating 3D modeling of structural work using Tekla Student Version software in working on bar bending schedules. Tekla software can produce iron calculations on beams and columns assisted by Microsoft Excel software. The calculation results from Tekla will be compared with conventional methods, comparisons will also be made regarding processing time, calculations, cost estimates and material waste in beam column reinforcing steel.It is hoped that this can provide an illustration that using computer software is more effective, efficient and can minimize material waste. So research is needed in implementing the BIM concept to see the differences in results between software and (conventional) project data. The building used as the research object is the Inkasa Office Project Construction, Kertajaya Office which is located in the city of Surabaya, East Java, has 5 floors + 1 roof, a land area of 33m long, 27m wide and a building area of 468m2. The function of the building is as an office.

Abstract

Concrete is a material that is commonly used when doing construction work today. Because concrete has several advantages when compared to other materials, such as being easy to form, resistant to weather changes, has high compressive strength, and is durable. In this study the use of Silica Fume as an additive to flow concrete has the function of improving the quality of flowing concrete. Silica Fume has an important role in affecting the chemical and mechanical properties of concrete. Judging from its chemical properties, Silica Fume geometrically fills the voids between cement materials, and causes the pore diameter to decrease and the total pore volume to decrease. Meanwhile, from its mechanical properties, Silica Fume has a pozzolanic reaction (a material containing silica/silica dioxide and alumina compounds) which reacts to the limestone released by the cement. The aim of the research is to increase the maximum compressive strength of flowing concrete by using Silica Fume added with varying percentages of 0%, 5%, 6%, 7.5%, 9%, 10.5% and 12% and using a superplasticizer of 1.5 %. From the results of the research conducted, it was found that flowing concrete with added silica fume on concrete compressive strength was able to reach 7.5% at 7 days of age of 25.91 MPa and at 28 days of concrete age was obtained at 26.19 MPa.

Abstract

Dengan wilayah kehutanan yang luas dan beragam, Indonesia menjadi penghasil berbagai jenis tanaman hutan, termasuk kayu jati yang produksinya mencapai 68,22 juta per tahunnya. jumlah limbah serbuk kayu hasil penggergajian di Indonesia diperkirakan mencapai 0,78 juta per tahun. Penelitian ini fokus pada limbah serbuk kayu yang pemanfaatannya masih belum optimal, namun memiliki potensi setelah melalui proses pembakaran menjadi abu. Material tersebut mengandung silika sebesar 61,10% yang merupakan salah satu bahan utama dalam pembuatan semen yang akan mengeras ketika bereaksi dengan air dan kalsium hidroksida hasil dari hidrasi semen. Penelitian ini menggunakan metode eksperimen laboratorium dengan variasi abu kayu jati (AKJ) sebanyak 0%, 5%, 7,5%, 10%, 12,5% yang telah lolos ayakan No.200. Pengujian dilakukan terhadap workability dan daya serap mortar. Namun dengan semakin banyak kadar abu membuat workability mortar semakin menurun dan resapan mortar semakin naik karena abu kayu cenderung memiliki sifat menyerap air. Hasil uji resapan menunjukkan bahwa variai 12,5% menghasilkan nilai resapan tertinggi, yaitu sebesar 9,672%.
