The main objective of the present work is to study the present situation of the precast construction industry in India. Suggestions for improvement of the industry and study on cost effectiveness of precast concrete construction for single and multi-story residential buildings are to be given. A literature survey was carried out in order to obtain the comparison between the conventional buildin...

The Precast Concrete Industry (PCI) is one of the major contributors to the national economy and can be categorised as labor-intensive industry. It is currently experiencing shortcomings in terms of delivery products at a competitive cost and time. This is mainly due to the inefficiencies associate with planning and scheduling of skilled operators within crews configurations. This paper present...

Concrete is the second most utilized substance around world behind water. The aim of this paper to review environmental effect concrete industry. It has been found that impact industry severe in various categories as global warming, depletion ozone layer, and acidification soil water bodies. Moreover, affects ecosystems alters hydrogeological hydrological systems. Green become increasingly popu...

Elevated rail transit has been developed in some big cities in China in recent years. However, specialized codes for design of the bridges in the elevated rail transit system have not yet been established. Based on the prestressed concrete (PC) box girder bridges on Guangzhou metro line 4, some technical features of design principle and technology requisition, ensemble plan and design load of b...

the marble slurry wastes (msw) produced by marble industry is left unattended in theenvironment which causes serious environmental problems. in order to evaluate its potential usage in normal1:2:4 concrete, this study was designed, where the partial replacement of cement with msw was examined.replacement of cement with msw from 0 to 100%, and also its usage as an additive material 10% and 20% b...

Ground granulated blast furnace slag is widely used as a mineral admixture to replace partial Portland cement in the concrete industry. As the amount of slag increases, the late-age compressive strength of concrete mixtures increases. However, after an optimum point, any further increase in slag does not improve the late-age compressive strength. This optimum replacement ratio of slag is a cruc...

Concrete is an essential building material which is widely used in construction industry all over the world due to its compressible strength. Curing of concrete plays a vital role in durability and other performance necessities. Improper curing can affect the concrete performance and durability easily. When areas like scarcity of water, structures is not accessible by humans external curing can...
