Published: December 2022

Abstract
Sustainability is the goal pursued by societies worldwide. Existing buildings have had their share of those issues, specifically healthcare buildings, as most governments encourage green new construction and neglect existing buildings. Additionally, the benefits of existing buildings in preserving the environment, and its resources and reducing energy and global warming crises. The research objective is to achieve a high-level performance of existing healthcare buildings within a framework of evaluating the most important determinants affecting these buildings.
The paper will focus on presenting the different rating systems such as LEED and BREEAM, by dividing and analyzing these systems, given that each system has its own standards and how it scores evaluation points. As the rating systems help in improving the existing healthcare buildings and get low-negative environmental impacts; they will reduce pollution, reduce carbon emissions, choose non-polluting and sustainable materials, encourage the use of recycled materials, and control waste management.
The paper presents an approach to find out which rating system will evaluate green existing healthcare.

Authors: Alothman R A T , Abdin A R , Mahmoud A H 
Published: December 2022

Abstract
CO2 emissions are known as carbon emissions and they are increasing globally, so measures must be taken to reduce their emissions and find solutions that mitigate the effects of high rates of emissions. CO2 emissions are currently increasing, and the construction sector is the largest source of these emissions, accounting for 39% of total emissions; therefore, CO2 emissions must be reduced as much as possible. The research aim is to study the effect of applying vegetated façades, in multistory residential buildings on the CO2 emissions under two different climates, cold semiarid and hot arid. The tool which is used is a DesignBuilder to evaluate the CO2 emissions. Thermal insulation contributes to reducing the carbon footprint of the building and consider as an additional layer applied to the bare wall façade as the same as the vegetation layer therefore in this research the comparison will be between the use of insulation materials and green façade with a bare wall façade of residential buildings to determine the effectiveness of using vegetated facades in reducing CO2 emissions. The study found that vegetated facades reduce CO2 emissions from 36.2 to 51.4 in cold semiarid climates and from 18% to 37.6% in hot arid climates.

Published: December 2022

Abstract
The application of polymer in an asphalt concrete (AC) mixture has reached wide popularity lately to deal with the increasing demand for higher quality roads with heavier traffic loading. Ethylene-vinyl acetate (EVA), classified as a thermoplastic, is currently one of the most popular polymers employed. This research attempts to evaluate the effect of adding EVA by means of the dry method, namely by pouring the additive directly into the mixture, which produces both hot and warm Polymer-Modified Asphalt Concrete (PMAC) mix. FTIR result indicates the polymer as a thermoplastic material. Moreover, the volumetric and mechanical properties of the mixture were examined through the density and semi-circular bending (SCB) tests. The outcomes show that the inclusion of the polymer could slightly modify the density and VMA of the AC mix. Meanwhile, the tensile strength, fracture energy, crack resistance index (CRI), and flexibility index (FI) results describe substantial enhancement brought by the polymer, with a generally increasing trend up 200% of the control mix. Conclusively, the application of polymer could enhance the physical and mechanical properties of hot and warm AC mixes with the optimum dosages of 5 and 6%. Additionally, the properties of warm PMA are somewhat comparable to the regular hot AC mix.

Abstract
Fiber Reinforced Polymer (FRP) is commonly used in structural repair and strengthening due to its high tensile strength, non-corrosive and lightweight. On the other side FRP is relatively brittle compared to steel. This study used hybrid FRP consisting of GFRP and CFRP, by combining two type of FRP with different characteristic it is to be expected that the more brittle FRP will fail first followed by the more elastic one, therefore creating a sequential failure. However CFRP have a higher tensile strength in comparison to GFRP, therefore it’s necessary to reduce its tensile strength by reducing its volume. This study is divided into two topics, hybrid FRP tensile strength test and beam flexural test. For the hybrid FRP tensile strength test, a total of three variation of hybrid FRP will be compared (GC30, GC40, and GC50). The variation that shown a sequential failure behaviour, will then be applied to a reinforced concrete beam and tested under monotonic point load device. The test result shown that sequential failure occur on GC30 and GC40. However GC40 had a higher ultimate load at 24.86 kN. For the beam flexural test, there will be two variation, i.e. control beam (CB) and beam strengthened with hybrid FRP (BGC). When compared, BGC had a 40.0% increase in yield strength and 55.43% increase for ultimate load.

Published: December 2022

Abstract
At the location of the Pamukkulu dam, it has engineering geological characteristics that are less supportive of the construction above it, especially for the foundation of the dam. By taking data directly in the field and by laboratory testing, information is needed regarding the characterization of mineralogy and the engineering properties of rocks. Mineralogical analysis was performed with petrography and X-Ray Diffraction (XRD) while the engineering properties of the rock were performed with Plate Bearing Tests (PBT), Standard Penetration Tests (SPT), and Rock Mass Rating (RMR). Based on mineralogical data, rocks have undergone weathering and converted the chemical-physical properties of minerals into porous, fine-grained minerals, forming mineral oxides as well as clay minerals. The carrying capacity of surface soils in the dam area based on the plate bearing test is relatively poor. As for subsurface rocks, the weight of the rock mass rating belongs to the class (II) Good to (III) Medium. Meanwhile, from the density value of hard soils, there are different depths from a depth of 1 meter to 6 meters. Weathering conditions of rocks affect the engineering value of soils and rocks where due to weathering minerals formed in the form of porous clay minerals, they are not well consolidated.

Abstract
In today’s world of construction, many use steel as reinforcement for reinforced concrete, where steel is one of the most widely produced materials to meet infrastructure needs. The use of steel is so rapid but has several drawbacks such as a less economical price and not environmentally friendly. In addition, the characteristics of bamboo plant materials that can be an alternative, where bamboo has a fiber that is good enough to withstand the same tensile strength as steel reinforcement that works in concrete construction. However, some things that must be considered are the air content which is quite influential on the tensile strength. This research focuses on the effect of water content in bamboo on the tensile strength of bamboo itself. The bamboo material used is Buluhpring bamboo from the Gowa Region, the bamboo is dried and tested for its characteristics. From the results of the water content test, the average water content was 34.44% on the bottom of bamboo, 25.89% on the middle bamboo and 14.89% on the upper bamboo where the Upper segment of bamboo have met ISO 22157 standards. -01-2004. The bamboo material was also tested for tensile strength of 277.54 Mpa at the bottom, 308.51 Mpa at the middle and 357.10 Mpa at the top. From the test results, it can be seen that the relationship between the water content of bamboo and the tensile strength of bamboo is that the smaller the water content contained in the bamboo, the higher the tensile strength of the bamboo material accepted by bamboo.

Published: December 2022

Abstract
Concrete is the most widely used construction material as building material because it has advantages such as easy workability, high compressive strength, and economical in terms of manufacturing and maintenance. However, there are some disadvantages obtained from the use of concrete, such as low tensile strength, easy cracking, and brittleness. Therefore, it is necessary to add fiber to the concrete to increase the ductility and use of SCC concrete to maintain workability after fiber substitution. The variation in the addition of nylon fiber is 0.5% and 1% to the weight of cement with a diameter of 0.35 mm and 0.65 mm, a length of 15 mm, and 20 mm. With the addition of 1% of 0.65 mm diameter and 15 mm length, the compressive strength of SCC concrete increased by 126%. The nylon fiber was also found to be evenly distributed in the concrete mixture and did not experience clumping and the volume weight of the concrete was reduced by 5-7% of the normal concrete. The SEM results show a clear interface between concrete and nylon fiber, and the slippery morphology of nylon fiber causes the bonding with concrete to become weak.

Abstract
The characteristics of peat soil with high organic and moisture content, also high compressibility can cause structural failure due to excessive settlement. Improvement of peat soil settlement parameters can be conducted using calcite precipitation method with soybean as bio-catalyst, namely Soybean Crude Urease-Calcite Precipitation (SCU-CP). SCU-CP is one of the grouting methods to improve soil consistency so that the bearing capacity of the soil increases. The purpose of this study was to analyze the increase in the parameters of the settlement parameter (R90) and the time at 90% degree of compression (t90). This study was conducted using a density of 90% Proctor standard compaction and the variation of untreated and treated samples. The optimum combination SCU-CP solution was used in the treated samples with a concentration of reagents (Urea and CaCl2) of 1 mol/L and soybean concentration of 20 g/L. The results proved that using the optimum combination of SCU-CP method, it could significantly improved soil settlement parameter of R90 and t90. The R90 values for untreated samples (UT) at each pressure of 2.0 kg/cm2, 4.0 kg/cm2, and 8.0 kg/cm2 obtained 39 mm, 86.7 mm, and 162 mm respectively. The improvement on R90 values of treated samples (TE) obtained 16.4 mm, 28.1 mm, and 57.5 mm respectively after being treated with the SCU-CP method. In the treated samples (TE) the t90 value is lower than untreated samples which indicates that the time to reach 90% consolidation is getting faster.
