Delay Pattern Assessment in Concrete Casting

Abstract

Urlabari Construction management is mainly concerned with time, cost and quality of a project. Concrete is mostly used construction material and its quality characteristics is important. With poor knowledge in concrete mixing and placing activities though the structures are structurally designed will have a great impact on the compressive strength of the structural elements and the life of the structure as a whole. The main objective of this research was to analyze through Field based observation the delay pattern in concrete casting on selected construction sites of Jhapa district.During field observation on selected construction sites of Jhapa district, the casting delay was mainly observed in manual mixing and in case of ready mix concrete. Use of plasticizer was noted in case of ready mix concrete which helped to maintain workability even in case of delayed casting but in ordinary works of manual type, more time elapsed cases were observed which resulted in loss of workability and strength.
