Also, the increase in construction activities has led to the over exploitation of river beds for sand. In this present study, fine aggregates are replaced by iron ore tailings in M20 grade concrete at varying percentages of 20%,30%,40%,50%,60%. The cubes and cylinders were casted and their compressive strength and split tensile strength were evaluated for 7 days and 28 days. It is observed from the test results that the iron ore tailings aggregate concrete exhibited a good mechanical strength compared to the control mix. The compressive strength has increased with the increase in replacement of iron ore tailings in concrete, which has shown an improvement of 18.41% over conventional aggregate concrete. An incremental increase of 10.3 % was observed in the case of split tensile strength for 60 % replacement of fine aggregate with iron ore tailings.

When developing and building things, various disciplines must work closely together. Each discipline is responsible for providing a unique contribution to the overall design. The objects from other disciplines may, however, occupy the same position in space or the same orientation when the incomplete designs are merged known as 'clash'. A collision of this nature is frequently discovered during construction, necessitating a significant amount of extra time and price. To avoid clashes in the final design, early collaboration is essential. BIM automation techniques can do this and perhaps reduce clashes by coordination of 3D Models. A case study that comprised clash detection between architectural, structural, and MEP BIM models was used to conduct the inquiry. The current study used Autodesk Navisworks Manage and Autodesk Revit as BIM tools to design capabilities to streamline and automatically discover clashes. The analysis of the case study data showed that BIM is a useful tool for identifying conflicts between building components. And an investigative study was done to know the reason why these clashes are created during modeling based on the questioners answered by BIM Modelers. The findings emphasize the need for greater transparency in partnerships where designers from varied backgrounds can work on projects simultaneously. This open and inclusive approach may have an impact on how architects, engineers, and construction professionals are trained in the future.

Due to the increase in urbanisation and industrialization, a large quantity of industrial waste is produced in developing as well as developed countries, and the unscientific disposal of this industrial waste is creating huge environmental problems. In this study, an attempt is made to incorporate both the problems and to find an alternative for natural aggregates with industrial by-products fly ash and GGBS for manufacturing artificial aggregates by adopting the geo-polymerization technique. The characteristic strength, flexural strength, and split tensile strength of geopolymer aggregate (GPA) concrete for varying percentage replacements, such as 25%, 50%, 75%, and 100% for natural coarse aggregates, have been studied and compared with normal concrete. Based on the test results, geopolymer agg...

Several studies have been carried out in past decades to identify the use of supplementary cementitious material in concrete. To increase the durability along with strength of concrete leads to the use of high-strength concrete which is more beneficial for environmental attacks on the structure. Various studies are performed on HSC with respect to workability, strength and durability. The addition of different mineral and chemical admixtures increases the strength and durability of HSC. The effect of SCM on strength and durability of High Strength Concrete (HPC) using ground granulated blast-furnace slag (GGBS) with Alccofine and GGBS with silica fume is studied.

Construction Planning is the necessary warning to Scheduling and determining general sequence, defining labour tasks, construction methods and assigning responsibilities, inappropriate planning can lead to major delays in the project work. For the planning and scheduling work huge amount of paperwork, which makes the management very burdensome. These problems can be solved using a project management software which helps to give a planned approach to planning. Nowadays use of project management (PM) software as a tool for managing and organizing work has gained its importance in construction industry and continues to grow at a faster pace in all other industries also. In this study, an attempt is done to compare the project management software such as MS project, Primavera and BIM and their feasibility is studied.

A little thought reveals that the amount of time needed to accomplish the job is inversely related to the availability of labor. When the number of workers is raised, the project's completion time is shortened; conversely, when the number of workers is reduced, the project's completion time is lengthened. The present study deals with the manpower, planning, scheduling and resource optimization of "Construction of a Villa Project at Chaitanya Sharan, Bengaluru", a two storied (G+2) building of 26 units whose construction is complete at Gunjur, Bengaluru, Karnataka. This study uses Microsoft Project 2013 to schedule various building activities, allocating resources, and level those resources in order to examine project management strategies. In essence, it relates to finding a solution to the project's excessive resource allocation. This project illustrates how resource levelling may be accomplished with Microsoft Project and what impact it might have on overall project duration.

The aggregates were manufactured using cement in lesser quantities and fl yash in excess quantity various trail mixes were conducted and fi nally a suitable mix is selected for large quantity production. Cubes, beams and cylinders were casted by partial replacing natural coarse aggregate by 25%, 30%, 35%, 40%, 45% and 50% of manufactured fl y ash aggregate. The strength parameters such as compressive strength, fl exural strength and split tensile strength of the casted cubes, beams and cylinders were tested respectively.

The use of supplementary cementitious materials as partial replacements for the cement in concrete will play a significant role with respect to the environmental control of greenhouse effects and global temperature reduction. The development of geopolymer concrete (GPC), processing of geopolymer using fly ash, GGBS in combination with sodium hydroxide and sodium silicate solutions, offers a promising alternative to ordinary portland cement concrete. This study compares the different ratios of fly ash to GGBS where, 50:50,60:40,40:60 ratios and differing the molarities of alkaline solutions which are 8M,10M and 12M and comparing the strengths of the above ratios and conducting durability characteristics of fly ash and GGBS based geopolymer concrete by conducting test procedures like acid attack test

The aggregates were manufactured using cement in lesser quantities and fly ash in excess quantity various trail mixes were conducted and finally a suitable mix is selected for large quantity production. Mix design for fly ash aggregate concrete is done by calculating the specific gravity and water absorption of the manufactured fly ash aggregate and quarry dust since both have lower specific gravity nominal mix M20 mix design cannot be used hence design mix is done. Since the specific gravity of the fine aggregate and coarse aggregate is less the obtained concrete is lighter in weight.
