introduction of this research topic which is construction waste during the construction stage. This chapter also consists of background study, problem statement, aim and objectives regarding to the topic that have been studied. There are also brief elaborations on scope of research, significance of research, outline methodology and thesis structure included in this chapter. The purpose of this chapter is to introduce the research topic which is construction waste on the perspective of Malaysian Contractor
Reasons for the slow progress in recycling of construction and demolition waste in India are a. The lack of awareness amongst the general public about the problems associated with the uncontrolled disposal of waste over many generations, waste has been viewed as something that is not fit for further use and must be discarded or destroyed. The resulting environmental, health and economic problems are not usually well documented or publicized, so that public awareness of these problems is often
from the waste concrete plays a huge task in providing the strength to the fresh concrete. For the sustainable growth, Engineers should have to decrease the utilization and exploit of natural resources or materials like sand, aggregates etc or they can use the diverse material for making a structure with the equivalent strength. The alternate method for this problem is to use the recycled aggregate from the waste concrete as an alternative of using fresh aggregates in the construction relevance’s
Waste minimization provides financial benefits in terms of reduced transportation cost, less disposal cost, minimized purchase quantity and price of raw materials, reduced purchase price of new materials when considering reuse and recycling, increased returns achieved by selling waste materials etc. Environmental benefits consist of minimized amounts of waste disposed off at landfills, which therefore extend the lifespan of landfills, reduced environmental effects as a result of disposal, e.g. noise
Lean construction is a way to design production systems to minimize waste of materials, time and effort in order to generate the maximum possible amount of value .It is also a holistic design and delivery philosophy with an overarching aim of maximizing value to all stakeholders through systematic, synergistic and continuous improvements in the contractual arrangements, product design and method of selection, the supply chain and the workflow reliability of site operations. Lean construction much
INTRODUCTION Sawdust powder molding technology is an engineered development in construction of boards of varying shapes and thickness. It involves utilization of sawdust that is normally disposed from the saw mill, wood construction practices such as furniture construction or wood making plants. These fine particles from sawdust can be mixed with resins to make boards of economic value by cold-compression .These products can be utilized in making of furniture, cabinet doors, deckig, and ceiling
countless projects. The investors / owners naturally have a right and are interested in “best value for the money spent” The construction projects, there are numbers of constraints which effect output e.g. Labor, Environment, Location etc. So, Zero wastage is not possible for any type of project. The aim of this study work is to find reasons of material wastage on construction site of multi storied buildings and how it can be minimized. So, overall project cost can be reduced or profit maximized. The
Building Materials of S11 House (322) Based on Materials and Resources (MR) criteria as listed in Green Building Index (GBI) as one of the six key criteria to design a green building in Malaysia and also worldwide, this section promotes the use of eco-friendly materials sourced from sustainable sources and recycling. Implementation of proper construction waste management with storage, collection and re-use of recyclables and construction formwork and waste are emphasized here. Building materials are
component layers namely Sub-grade, Sub-base and base and surface courses which are made up of materials like natural soils, sand, morrum etc., are proved to be costly in terms of construction as well as maintenance. Performance of Flexible Pavement depends on the functions of the component layers especially Sub-grade. Sub-grade is compacted layer of soil, provides the lateral support to the pavement. Construction over soft Sub-grade affects the performance of pavement and results in shorter life of pavement
INTRODUCTION Concrete is the most widely used man-made construction material. It is primarily obtained by mixing cement with aggregate and water. There are many formulations of concrete, which provide different properties. It can be moulded into any shape and surface can be textured and coloured for aesthetic purposes. Concrete is widely used in construction of foundations, architectural structures, pavements, bridges/overpasses, and motorways/roads, runways, parking structures, dams, pools/reservoirs
