“…Perbandingan Larutan Aktivator dan Pozzolanic material (FA dan GP) atau AA/PM ratio yang digunakan pada benda uji adalah sebesar 0,5. Pada penelitian ini, pembuatan paving blok berdasarkan (Hussain et al, 2021) menggunakan perbandingan berat Fly Ash : agregat halus : agregat kasar = 1 : 2 : 4. Pengujian kuat tekan dan penyerapan air akan dilakukan untuk menentukan mutu dari paving blok.…”

Fly ash merupakan salah satu bahan pozzolan yang diperoleh dari limbah hasil pembakaran batu bara. fly ash pada dasarnya tidak memiliki kemampuan mengikat seperti semen portland. Dibutuhkan larutan aktivator agar fly ash dapat memiliki daya ikat seperti semen portland. Selain fly ash, limbah kaca dari industri maupun rumah tangga dapat diolah untuk dapat dimanfaatkan sebagai material yang dapat memperbaiki kinerja bahan geopolimer karena mengandung senyawa silica (SiO2) dan zat kapur (CaO) yang cukup signifikan. Penelitian berfokus pada glass powder yang digunakan sebagai subtitusi fly ash pada paving blok geopolimer dengan persentase 0%, 15%, 30%, 45% dan 60%. Kinerja paving blok diuji berdasarakan kuat tekan dan penyerapan air. Pengujian dilakukan pada saat sampel berumur 7 hari. Hasil penelitian menunjukan bahwa nilai kuat tekan optimum terdapat pada paving block geopolymer dengan variasi glass powder 15% dan fly ash 85% yaitu 30,67 MPa yang termasuk paving block mutu B. Penyerapan air terendah terdapat pada paving block geopolymer variasi glass powder 15%, paving block yang dihasilkan pada penelitian ini adalah paving block dengan mutu B.

“…Because traffic congestion lowers the wellbeing of both drivers and city dwellers, it is a serious concern (Schoeman, 2018). The sustainability of mobility in an urban environment is impacted by traffic congestion, which is closely linked to the frequency of traffic accidents (Hussain et al, 2021) (Malik & Shah Faisal Saleh Faisal Farooq Rather Malik Jasif Jabbar, 2017;Sambucci & Valente, 2021). This includes the high additional social costs associated with traffic accidents as well as public policies aimed IOP Publishing doi:10.1088/1755-1315/1321/1/012049 2 at reducing congestion, which is fundamental to today's cities.…”

Factors that cause accidents include traffic characteristics and road infrastructure, environmental conditions, vehicle design and specifications, and human factors. The object of this study is road infrastructure, namely the road structure at traffic light stops points because the accident hazard at crossroads is a determinant of traffic safety and driving comfort. In Coastal Area/Upstream Area, To overcome road infrastructure problems at traffic light points which are the cause of traffic safety and driving comfort, the design of Concrete block pavement is one of the solutions to overcome these problems. Concrete block pavement is often used for the construction of sidewalks, bicycle paths, residential driveways, parking lots, industrial areas as well as harbors and airports and other permeable areas. Concrete block pavement is used in Europe in extreme weather. Specially designed concrete block pavement innovations can withstand heavy static traffic loads such as rigid pavements, and these can be readjusted easily if a change in pavement layout is required. The method used in this study uses pure experimentation with the parameters of the variation of the pattern, the variation of the type, and the variation of the dimensions. This research uses the Autocad, PLAXIS and SAP2000 programs. This program finds moments and deformations that occur in the modeled paving blocks as well as soil deflections that occur due to deformation loads in various shapes (brick). The results obtained from the analysis of previous research show that there is the most optimum shape among the brick paving block shapes with a thickness of 6, 8 and 10 cm. The way to determine it is to make a paving block preparation simulation with the SketchUp, PLAXIS and SAP2000 programs. From the program calculations, the interlocking aspects, land subsidence and deformation aspects are produced.

“…Gao et al used super-thin-layer mortar smeared on both sides of sintered blocks, achieving 84% and 89% of a high-cost commercial mortar [26]. Different substitutions have also been studied in the manufacture of pavers such as low-calcium and granulated blast furnace slag [27], steel slag powder [28], rice husk ash [29], processed waste tea ash [30], steel fibers [31,32], crushed glass and granulated blast furnace slag [33], shredded plastic waste, powdered ceramic waste [34], olive wood waste [35], and fly ash and microsilica [36].…”

Among the construction products manufactured with Portland cement (PC) are (in addition to hydraulic concrete) construction blocks. These elements are used as masonry materials for the elaboration of walls in all types of construction. For the elaboration of these elements, large amounts of geomaterials such as sand are utilized. The aim of this investigation was to reduce the consumption of geomaterials using block manufacturing that incorporates construction and demolition waste as a substitute for gravel and tire flakes as a substitute for sand. These blocks were characterized by their resistance in a compression test, flexion, modulus of elasticity, electrical resistivity, moisture absorption, and MEB microscopy, as well as an analysis of the unit price for different mixtures. The results show that the addition of tire flakes severely decreased the blocks’ physical-mechanical performance and increased the production costs, while the incorporation of 50% construction and demolition waste achieved a performance very close to that of the control blocks and presented improvements in the modulus of elasticity, although the costs could be higher than those for the control blocks.
