Presenting a Selected Method for the Industrial Use of Roller Concrete through Pavement

Several methods have been proposed by organizations and concrete committees to determine the mixing ratios of RCCP. These methods are generally experimental, semi-experimental, and based on theoretical methods. Although, generally, in different methods of mixing ratio design, two approaches of soil density and psychological (efficiency) approach are used. These two approaches are respectively defined based on the optimization of the dry density of the sample by the optimal moisture content and the mixing plan by the absolute volume. In this article, the various methods presented to determine the mixing ratios of roller concrete have been investigated. These methods are experimental and are based on making several test mixtures to determine the optimal design. In recent years and with the development of the application of mathematical models in the concrete mixing design, the use of semi-empirical and theoretical methods instead of experimental methods to determine the mixing design resulted in a significant improvement in the properties of the fresh and hardened roller concrete mixture, as well as reducing the number of experimental mixtures. In this article, the different stages of two recent methods of pavement roller concrete mixing design, including the optimal volume model of the paste (semi-experimental method) and the compressible compression model (theoretical method), are presented, and the assumptions, considerations, and achievements of each are discussed

(*Review Article) Research on Privatization Reform of China's Loss-making Public Utilities

In this paper, an exposition of the background of China's privatization reform in public utilities, along with an analysis of the reform's content and effectiveness, is presented and organized based on relevant public administration theory and practice. Secondly, a thorough examination of the factors constituting the primary obstacle in China's privatization reform of public utilities is undertaken. Addressing issues arising from private companies pursuing profit while public utility entities seek to avoid losses, it is argued that the incomplete reform of government functions, the constraints of traditional ideology, and the lack of supervision in the privatization of public utilities contribute to these challenges. Finally, recommendations for loss-making public utilities in the privatization reform are put forth. These involve further reforms in the utilities' business model, the establishment of new operational and service paradigms, and the enhancement of government support,regulatory measures,and coordination during the reform process. These measures aim to address the existing challenges in China's loss-making public utilities during the privatization reform

Improving Tensile Strength and Strength and Resilience of Reinforced Concrete through Pozzolanic Materials

So far, there have been many definitions of concrete. According to these definitions, concrete consists of three main materials. These materials include cement materials, water with which cement materials react and become sticky; and fillers that make up a significant volume of concrete. Steel reinforcements reinforce concrete under tension, but they have almost no effect on the Turkish development process. In other words, when the end of the crack reaches the position of the tensile reinforcements, the rate of crack opening increases and also the crack propagation decreases, and then when the crack passes through the reinforcement, the crack development increases at a higher rate. In addition, the presence of reinforcement in certain tensile areas makes the concrete out of homogeneity and homogeneity, and the assumption of concrete homogeneity in analysis methods faces problems. The various advantages of using fibers in concrete, such as increasing bending strength, increasing shear strength, increasing tensile strength, increasing resistance to impact loads, increasing the amount of energy absorption, and increasing cross-sectional resistance against cracking, have caused the use of fibers in strengthening and repairing all kinds of structures. Concrete should be used. The results of the compressive strength test in samples reinforced with 1.5% and 2.5% glass fibers are as follows: The use of glass fibers in this research has reduced the effectiveness of concrete. According to these results, if glass fibers are used, the compressive strength of the samples is greatly reduced. The use of pozzolanic materials has significantly increased the compressive strength of concrete reinforced with glass fibers. Based on this, the highest compressive strength of 7 days and 28 days is related to samples reinforced with 2.5% glass fibers and containing metakaolin. In the samples reinforced with 2.5% glass fibers, with the increase in the amount of metakaolin used from 10% to 15%, the 28-day strength of the samples increased from 53.665 MPa to 56.16 MPa

(*Review Article) Urban Development and Architectural Manifestations of the Parthian Period of Iran (III BC-III AD centuries)

The presented article explores the urban development and architectural manifestations of the Parthian period in Iran, spanning from the III century BC to the III century AD. During this era, the Parthian Empire emerged as a formidable power, influencing art, culture, and urban planning across a vast territory. Key cities such as Nisa, Ctesiphon, Hecatompylos, and others serve as focal points for examining innovations in city design that integrate Persian and other regional influences (Greco-Hellenistic, Roman, etc.). Architectural features, including monumental arches, extensive use of vaults, and decorative brickwork, reflect a synthesis of regional styles and advancements in construction techniques. The examination of archaeological findings, such as the remains of the Tagh-e Kasra archway and the layout of urban centers, reveals insights into the socio-political structure, trade networks, and cultural exchanges of the time. This article highlights how the Parthians not only inherited architectural traditions (from the Achaemenids and others) but also adapted and transformed them, resulting in a unique urban landscape that laid the groundwork for subsequent Islamic architecture

Analysis and Determination of Factors Affecting Flexibility (UR) and Urban Sustainability (US)

Cities are increasingly becoming complex systems of social, economic, and ecological factors. When any of their subsystems are destroyed or unable to adapt to new challenges, they are highly vulnerable. Unknown factors such as natural disasters, climate change, energy crises, political instability, financial crises, food health, and terrorist attacks play an important role in threatening urban development. Three scales of urban, community, and urban facilities are outlined. To study and prepare the questionnaire in this study, two scales of community and urban facilities are considered. Accuracy was not possible. The results of the study showed that the indicators considered in the flexibility section are more important than urban sustainability, meaning that when flexibility is implemented in cities, the city will move towards sustainability. Other important results of the research are the implementation of poverty alleviation programs, the establishment of social poverty alleviation programs with the participation of the private sector, the number and value of small business loans, and the allocation of funds for poverty alleviation programs as influential factors in community management. There are two modes of flexibility and stability

Application of BIM in Energy Conservation in Low-Cost Housing in Case of Study in Dallas Independent School Residential District, Texas

Building Information Modeling is used to build and manage data throughout the project lifecycle from design, construction, and operations. In this technology, multi-threaded data is used to create detailed virtual views in a cloud platform, which allows project members to collaborate in real-time without wasting time. It can also operate and manage the building by using the data that the owners of the building or structure have access to. This data allows governments, municipalities, and property managers to make informed decisions based on information derived from the model, even after the building is constructed. This research, using quantitative methodology, aims to investigate the current state of BIM performance regarding the approaches of converting "affordable residential housing" to "green affordable housing" by reducing the cost of maintaining units and improving their quality with a focus on saving in energy through the implementation of construction details using BIM. In this regard, the Independent School Residential District in Dallas, Texas, and the residential complex built by the government for low-income groups were selected. The main question of the research is whether the behavioral modeling of the residents and the building together can act as an efficiency tool to increase the energy efficiency in the building. Finally, it was found that in low-cost housing such as social housing produced in Texas under the title of housing for low-income society, building information modeling along with user behavior modeling of these buildings together can be a powerful tool to increase building productivity and reducing current costs in the hands of designers and builders

Evaluation and Optimization of Building Greening Methods in Four Different Climates Using Building Information Modeling (BIM)

BIM, which stands for Building Information Modeling, is a methodology that allows architects to digitally simulate their design and manage all the information related to an architectural project. BIM systems include the fourth dimension (time dimension) and the fifth dimension (cost dimension). On the other hand, sustainable development is a complex concept that includes different aspects. In sustainability, the three economic, environmental, and social aspects are fully interacting with each other, and most researchers examine sustainability in these three main aspects (Triple Bottom Line) of environmental, social, and economic sustainability. Therefore, in this research, we have examined four objectives, which first evaluate the impact of building orientation on reducing energy consumption by using building information modeling (BIM) and determine the most optimal direction. Then we examine the effect of the placement of skylights and openings on reducing energy consumption by using building information modeling (BIM). Finally, we examine the effect of using green facades and building smartness on the energy consumption of the building. Finally, by comparing the results obtained from the Design-Builder software, the most optimal modes are determined
