Effect of Remixing & Intermittent Curing Sequences on Strength of Pavement Quality Concrete
The paper is concerned with determining the effect of remixing of two different grades of concrete proving blend ratio, time lag & intermittent curing sequence. Two mix designs (M40 & M50) selected and provide blend ratio (0 to infinity) at 0,30,60,90 & 120min time lag. In this research, the problem related to improper casting & curing sequence, which ultimate formation of the cold joint due to old and fresh concrete. Curing method applied with four sequences Air0 Water28, Air28 Water0, Air7 Water21, and Air21 Water7.Concrete samples were made and tested for their compressive strength, flexural strength, elastic modulus, and shrinkage properties in the laboratory. As compared to the strength of freshly prepared concretes to the hard in situ concrete tends to show a reduction in its various strengths due to improper curing & formation of cold joints. This reduction is further possible to be minimized to a certain extent on blending some quantity of a relatively fresh mix to the existing quantity of the hard in situ concrete.
