History itself is the evident that from the years together the people moves to the region where they can satisfy their needs and wants with fewer efforts and more opportunities. This thought lead to accumulation of people in some areas resulting in urbanization. As this urban area contributes highly in nation’s economy even the government announce a far reaching program of investments in urban development. However, these urban agglomerations manifest generally unsustainable ecologies. The depletion of material resources, the accumulation of waste, and the over-expenditure of non-renewable energy are direct consequences of the predatory expansion of urbanization. Out of this the major contribution goes to construction industry as the data reveals that Construction is responsible for 40% of the total world flows of raw materials such as sand, gravel& clay. It takes one quarter of all virgin wood, 40% of energy use,16% of water withdrawals,& produces 17% of all waste generated. This problems can be tackle efficiently it the waste generated by industries can be reuse for the purpose of making construction material. With little logic and application of basic science the new material that can be made by mixing waste may prove energy efficient if its thermal resistivity is enhanced and utilized. The research over here is a paradigm of such two waste mix building component with high thermal resistive property. The paper is about the making and testing of waste mix tiles and filler blocks so as to find its efficiency in construction practices. The results obtained shows that by adopting such materials for construction purpose will reduce amount of operations energy consumption as well as reduce consumption of non – renewable resources and would help to utilize waste in fruitful way. The effort in this research are thus to find energy efficient construction material.

In current research, building modelling and energy simulation tools were used to analyse and estimate the energy use of dwellings in order to reduce the annual energy use in multifamily dwellings. A three-story residential building located in Kabul city was modelled in Revit and all required parameters for running energy simulation were set. A Total of 126 experiments were conducted to estimate annual energy loads of the building. Different combinations from various components such as walls, roofs, floors, doors, and windows were created and simulated. Ultimately, the most energy efficient option in the context of Afghan dwellings was figured out. The building components consist of different locally available construction materials currently used in buildings in Afghanistan. Furthermore, the best energy efficient option was simulated by varying, building orientation in 15-degree increments and glazing area from 10% to 60% to find the most energy efficient combination. It was found that combination No. 48 was best option from energy conservation point of view and 120-degree rotational angle from north to east, of the existing building was the most energy-efficient option. Also, it was observed that 60% glazing area model consumed 24549 kWh more electricity compared to the one with 10% glazing area.

Natural Aggregates

Construction is growing rapidly nowadays. Buildings, housing, industry/business centers and highways will require natural aggregates which are natural resources that cannot be renewed. Therefore, we need replacement materials able to replace these natural aggregate. The large amount of plastic waste in fields, based on existing data, causes environmental pollution through it can be reused and useful for building and road construction. Most of communities don’t even know the plastic waste processing technology that allow their use in the construction of house construction such as floors, walls, roofs, and hinges and also road construction with not heavy road loads. The purpose of this activity is to provide the knowledge to the people of RPTRA related to technology for the use of plastic waste for building materials and also road construction in the area in the RPTRA environment considering it is not a public road and hence, with not heavy vehicle. The method used is firstly observation and interview of several houses visited. Then activities about using different types of plastic waste as construction materials. Finally, evaluation of the progress of the project by conducting a survey to people who had met the criteria of being a member of the plastic waste program. The success of this program will be the people’s understanding and a significate growing of any highvalue plastic use as construction material. The benefit of this community service is to increase the knowledge and insight of the people of RPTRA, South Meruya, and West Jakarta City, related to environmentally friendly technologies such as plastic waste processing.

Treatment of municipal wastewater results worldwide in the production of large amounts of sewage sludge. The major part of the dry matter content of this sludge consists of nontoxic organic compounds, in general a combination of primary sludge and secondary (microbiological) sludge. The sludge also contains a substantial amount of inorganic material and a small amount of toxic components. The large volume of wastewater sludge generated requires enormous landfill space for disposal. Diverting the wastewater sludge from landfill would alleviate the shortage of landfill sites. Thus alternative applications have to be considered for the wastewater sludge diverted away from the landfills. The use of wastewater sludge for the production of construction materials is reviewed in this paper. Wastewater sludge can be used as raw materials for making bricks, concrete filler and concrete aggregates. The study reveals that the reuse of wastewater sludge as construction materials offers a technically feasible alternative for sludge disposal.

In Islamic law, khamr is a common type of alcoholic beverage that is forbidden for consumption due to its elements that can intoxicate and lead to loss of self-control. The government of Indonesia also forbids people from consuming the intoxicating beverage in certain levels. Nevertheless, a community group in Batu Payuang Halaban, Lima Puluh Kota Regency, West Sumatra Province, Indonesia, wherein their daily lives can be found a type of traditional beverage as same as khamr that is a fermented juice of sugar palm bunches. The people call it “tuak”. This research aims to investigate how the people of Nagari Batu Payuang produce aia niro and tuak, their motives for buying, selling, and consuming the drink, and judging it from the perspective of Islamic law (hadd al-syurb). This type of research is field research with a qualitative approach. Data sources consisted of primary and secondary. The data collection was conducted by observing the process of producing aia niro, tuak, and the transaction, and in-depth interviews with owners of sugar palm plantation, tuak producers, buyers, sellers, consumers, and local ulama (Islamic scholars). The data were analyzed in descriptive by reduction, display, and verification. To examine this research, the theory used was the concept of hadd al-syurb in Islamic law and the regulation on alcoholic beverages in Indonesia. The results show that aia niro is produced by extracting the bunches of male sugar palm and it is the raw material to produce tuak by leaving the aia niro in jerry cans and adding agarwood bark for 3 days. The sellers have various reasons to sell tuak and its raw materials. Besides the price is higher than brown sugar, it is also motivated by personal and other economic reasons as well as easier processing. People who drink tuak realize that it is intoxicating in a certain amount but they drink it to warm their bodies and relieve their fatigues. In the concept of hadd al-syurb, consuming tuak as an intoxicating substance is haram (forbidden) and is condemned to those who drink it. However, they who trade it are not punished by hudud since the Sunna proposition only refers to the transaction as an act of curse.

Development of the infrastructure is favorable for the growth and economy for any country; however, the issues to manage construction waste due originating from development exercises is a noteworthy reason for concern. The waste from construction contributes to negative repercussions on time, cost, productivity, and environment. Therefore, to reduce these negative and undesirable effects, a detailed review of waste generation and management must be provided. The significant construction waste causes were identified and grouped into seven clusters: construction management, design, construction material procurement, construction material handling, construction site condition, and external factor. A total of 150 questionnaire survey forms were distributed to professionals working on the Riyadh metro project, and only 118 questionnaire forms were received. The collected data from the questionnaire is analyzed using the average index and factor analysis. Analysis identified that ‘Design errors; ‘Accidents; ‘Damage during handling’; ‘Communication problems; ‘Frequent variation orders’ ; ‘Congestion of the site’ and ‘Damage caused by workers’; are highest significant causes in each category respectively. Furthermore, factor analysis was conducted through Exploratory Factor Analysis (EFA) technique to the top fifteen (15) factors and found five factors responsible for the construction waste was identified such as management, workers issues, material related issues, improper handling, and design. The findings from this study are useful for policymakers to develop or/and enhance recommendations on construction waste generation to prevent problems in construction industries. The government or building industry should establish or strengthen regulations that regulates how construction materials should be disposed of.

The Impact

Concrete has been used in the construction industry since long times. It is probably the most widely used construction material in the world, largely due to the abundance of the raw materials for cement manufacture, low relative cost and the versatility and adaptability of concrete in forming various structural shapes. Massive production of concrete and the associated substantial manufacture of cement have however been observed to have a very negative impact. One of the biggest issues of growing concern at the moment faced by concrete industries is the impact of cement production on the environment. The production of cement not only depletes significant amount of natural resources, but also liberates a considerable amount of carbon dioxide (CO2) and other greenhouse gases into the atmosphere as a result of decarbonation of limestone and the combustion of fossil fuels. In addition, cement is among the most energy intensive construction materials, after aluminium and steel [1].

Investigation of the above is oriented on solution of such scientific problem as more deep understanding of structure and features of material. The results obtained also allow solution of some technological, technical and economical tasks. Greatly, it is actual when using of new types of raw materials as well as when synthesis of new composites. Concerning the construction material science field, the classic problem is the looking for ways to study the reactivity of raw components under different conditions, its control and, generally, its increasing to produce higher performance materials. Among the popular and widely-used construction materials are alkali-activated binders and relevant composites. In this study the results of granulometric analysis of suspension based on alkali-activated aluminosilicate with different crystallinity degree are presented. It was found, when treatment of aluminosilicate grain by alkali activator leads to the grain solubilizing (but differently depending on crystallinity degree of aluminosilicate) and formation of alkali-aluminosilicate gel that reacts with unreacted part of the grain according to structure affinity principle. It was also determined the crystallinity degree of aluminosilicate component is inversely proportional to its solubility in highly-alkali environment. The model of structure formation for geopolymer system under alkali effect is offered.

Due to increased construction practices there was a very high demand in consumption of raw materials that are to be used in concrete. In the raw materials, sand is one of the major construction materials that is consumed adequately. It’s presence will be vanished due to excessive digging .The effect will be to the nearby localities .As well the stability hydraulic structures nearby river banks will be affected with this. To reduce digging practices the fine aggregate was partially replaced with waste crushed glass in 0%,10%,20%,30% andv40% along with 0.25%Super plasticizer SP 430 to achieve workability. The crushed glass is non-biodegradable and cannot be disposed off, also causes several environmental effects. By utilizing this waste as a useful material in the form as replacing material of fine aggregate we can reduce the waste content and in the same way it can be used as a resource. In order to check the concrete strength and durability tests like Compressive strength test, Split tensile strength test, Flexural strength test for 7,14,28 days curing and acid attack test, rapid chloride permeability test, Abrasion tests were conducted. SEM tests are also conducted on concrete with replaced fine aggregate. The current research work describes the proper utilization of waste crushed glass as a useful construction material.
