Comparative Adsorption Studies on Raw Rice Husk, Acid Leached Rice Husk and Base Leached Rice Husk by Using Methylene Blue as Dye
Abstract: Current methods for removing dyes from wastewaters are costly and cannot effectively be used to treat wide range of such wastewaters. This work describes the use of raw rice husk (RRH), acid-leached rice husk (ALRH) and base-leached rice husk (BLRH) as adsorbents for decolorization. Characterization of raw rice was done by powder X-ray diffraction (P-XRD) analysis, surface area analysis and scanning electron microscopy. Raw rice husk was collected directly from …

Performance of Polymer Modified Polypropylene Fiber Reinforced Concrete
Abstract: AbstractThe fiber reinforced concrete (FRC) is a composite material essentially consisting of conventional concrete reinforced by random dispersal of short, discontinuous and discrete fibers of specific geometry. The conventional plain concrete possesses high compressive strength, low tensile strength, poor impact strength, ductility, and little resistance to cracking and poor resistance to chemical attack. The presences of micro-cracks at the mortar aggregate interface are responsible for the inherent weakness of plain …

Ranking of Relative Importance of Productivity Factors in Indian Construction Projects
Abstract: Productivity remains an intriguing subject and a dominant issue in the construction sector. Best performance is unachievable with poor productivity resulting in time over-run and consequently cost escalation of projects. Hence, productivity is of critical importance to the profitability of most construction projects and it is essential that attempts to be made to improve productivity. Any improvement in productivity cannot be achieved without understanding the factors that adversely affect productivity. …

Liquidated Damages: The Perception of The Construction Industry
Abstract: There are several misconceptions about the term “liquidated damages” (LD) as many believe it is a penalty levied for delay or breach of contract. However, in a key judgement in a court it was presumed that LD is a sum payable upon breach and must be a genuine pre-estimate of the loss the innocent party would suffer in respect of the breach. If the intention of the LD is to …

Analysis of Cost and Schedule Performance of Residential Building Projects by EVM Technique
Abstract: Earned value management (EVM) is a project control technique which provides a quantitative measure of work performance by cost and schedule monitoring. It involves a crediting (earning) of budget as scheduled work is performed. The EVM technique is a proven method to evaluate work progress in order to identify schedule slippage and areas of budget overruns. Value earned for a given task is computed as budgeted cost of work performed …
