Abstract

Mortar is an important binding matrix in construction, playing a role in protecting structures from damage and cracking. Handling seepage and corrosion in structures is a major concern. Research shows that the addition of Acrylic Binder to mortar mixes improves weathering, chemical, abrasion resistance and adhesive strength. This study aims to assess the characteristics of mechanical and physical properties of mortar with the addition of acrylic binder in polymer mortar. The results of the study with the addition of acrylic binder through treatment in normal water and normal conditions with a variation of 3 substitutions namely 40%, 30%, 20% and 0% which is needed as a control, showed an increase in the highest compressive strength value in the addition of 30% acrylic binder with the strength obtained of 26 Mpa at the age of 28 days. The lowest water absorption was 4.35% at 28 days, with a porosity of 9.3% and surface absorption of 0.14. These results show that the addition of acrylic binder increases the water tightness of the mortar, demonstrating the potential application of this polymer mortar in improving structural performance.

Abstract

Fakultas Teknik Universitas Riau sebagai pusat pendidikan tentunya telah menyediakan fasilitas parkir untuk para civitas akademika. FT-UNRI mengalami peningkatan jumlah civitas akademika yang dimulai sejak adanya penambahan jurusan dan prodi baru. Peningkatan jumlah tersebut menyebabkan fasilitas parkir yang ada tidak memadai, hal ini dibuktikan dengan terdapat masalah pada fasilitas parkir yang tersedia seperti kendaraan yang parkir di luar petak parkir yang tersedia dan kendaraan yang parkir tidak tertata. Penelitian ini bertujuan untuk melihat karakteristik lahan parkir yang tersedia untuk nantinya dapat dilakukan upaya optimasi serta mendapatkan pemodelan untuk menghitung kebutuhan parkir sepeda motor dan kendaraan roda empat di FT-UNRI. Hasil analisis karakteristik parkir mobil terdapat indeks parkir sebesar 130,59% hal ini menunjukkan bahwa kebutuhan parkir melebihi kapasitas normal, untuk sepeda motor indeks parkir maksimum sebesar 78,94% hal ini menunjukkan bahwa fasilitas parkir memadai, namun kenyataan dilapangan masih terdapatnya kendaraan yang parkir di luar tempat yang disediakan. Model kebutuhan parkir sepeda motor adalah Y1 = -29,730 + 0,593 X1 + 6,129 X8 dan untuk parkir mobil adalah Y2 = -9,128 + 0,068 X4 + 0,422 X8. Kebutuhan parkir tahun 2022 untuk sepeda motor sebanyak 2441 SRP (Satuan Ruang Parkir) dan untuk mobil adalah sebanyak 128 SRP.

Abstract

The objective of the study is to investigate the mechanical properties of concrete with different replacement levels of Ordinary Portland Cement (OPC) by Rice Husk Ash (RHA). Two RHA replacement levels were considered in the study which is 5% and 10% by the weight of cement. After the specified initial curing period (28 days), specimens were immersed directly in peat water canal for 28 days. The mechanical properties was evaluated by measuring the compressive strength and tensile strength of the concrete specimens. The result shows that the compressive strength of OPC concrete is higher than OPC concrete using RHA as cementitious materials. A replacement level of 10% RHA in OPC concrete performs and shows better tensile strength than other replacements.Keywords : Mechanical properties, OPC, Rice Husk Ash (RHA), peat water

Abstract

Casting concrete underwater is concrete used for structural work underwater. The main problem in underwater casting is the separation of concrete constituent materials. Casting underwater also does not involve compaction. This study will examine the effect of peat water on the physical properties of underwater cast concrete. The additive used in this study is in liquid form, with a mixture of anti-washout material 1.8% and self-compacting concrete 5% to the weight of cement. The obtained slump flow value is 470 mm. The results of volume weight testing on variations of clean water mixtures immersed in clean water for seven days are 2248,14 kg/m3 and 2258,96 kg/m3 for 28 days, variations of clean water mixtures immersed in peat water for seven days are 2224,49 kg/m3 and 2219,39 kg/m3 for 28 days, and variations of peat water mixtures immersed in peat water for seven days are 2202,50 kg/m3 and 2191,08 kg/m3 for 28 days. The decrease in volume weight occurs in variations immersed in peat water. The results of porosity testing on 7-day and 28-day concrete age variations of peat water mixtures immersed in peat water are 9,94% and 10,78%, variations of clean water mixtures immersed in peat water are 9,84% and 10,28%, and variations of clean water mixtures immersed in clean water are 9,73% and 8,70%. The SEM test results show the surface shape of concrete using a magnification of 1000x, more pores on variations of peat water mixtures immersed in peat water, and variations of clean water mixtures immersed in peat water have uneven surfaces and pores. In contrast, variations of clean water mixtures immersed in clean water have better surfaces. The additive used can work well with peat water and clean water.

Abstract

Anti-washout concrete (AWC) is a specialized cement-based material designed to be applied directly in underwater environments, maintain mix integrity, and prevent material washout. AWC can. This research aims to evaluate the performance of anti-washout concrete in seawater environments containing chemical compounds aggressive to concrete, by examining the ability of concrete to withstand loads, resistance to washout, and structural stability when exposed to seawater environments. The test methods used included aggregate characteristics, slump flow, compressive strength, split tensile strength, and flexural strength at 7, 14, 28, and 56 days of concrete age. The results showed that concrete with fresh water (AB) had higher compressive, split tensile, and flexural strengths than concrete using artificial seawater (AL), with a decrease in compressive strength in AL against AB of 7.29% at 14 days, 11.20% at 28 days, and 12.69% at 56 days. AWC met the minimum compressive strength requirement of 70% of the Japan Society of Civil Engineers (JSCE) standard, indicating that AWC with artificial seawater remains viable for underwater construction applications. This study's results are expected to guide the use of anti-washout concrete for various underwater applications, particularly to improve durability and reduce long-term maintenance costs for underwater infrastructure.

Abstract

Permasalahan drainase di Desa Aur Sati Kecamatan Tambang Kabupaten Kampar adalah timbulnya genangan air di beberapa titik lokasi dan juga munculnya bau yg tak sedap akibat pembuangan limbah rumah tangga yang semrawut. Untuk memecahkan masalah drainase yang ada di desa Aur sati, maka langkah awal yang dilakukan adalah melakukan identifikasi masalah genangan banjir. Identifikasi dilakukan melalui wawancara, pengamatan lapangan, dan pengolahan data citra Lansat dengan geographic information sistem (GIS). Hasil penelitian menunjukkan bahwa genangan banjir terjadi di 3 titik yaitu di Dusun 1, Dusun 2 dan Dusun 4. Penyebab genangan tersebut adalah drainase yang belum terpadu, kondisi saluran drainase juga tidak layak, elevasi yang rendah dibanding sekelilingnya dan pembuangan sampah di saluran drainase sehingga mengakibatkan sumbatan di saluran. Untuk memecahkan masalah genangan banjir yang ada, hasil identifikasi yang telah dilakukan perlu ditindaklanjuti dengan evaluasi dimensi saluran tiap segmen genangan di masing-masing Dusun terdampak. Kata kunci:identifikasi masalah genangan, drainase, desa Aur Sati, sebaran genangan
