Influence of curing regime on strength development of grade C60 concrete
Journal Title: International Journal of Modern Engineering Research (IJMER) - Year 2013, Vol 3, Issue 2
Abstract
Abstract: Compressive strength of grade C60 concrete cubes cured in water and ambient air (uncured) were determined at 3, 7, 14, 28 and 90days. At 90 days, uncured specimens recorded strength reduction of 15.50% compared to control. Furthermore, cubes of the same grade of concrete were cured for limited durations in water and then removed and subsequently stored in air, and their compressive strength determined at 28 and 90 days. At test age of 28days, cubes that were water cured for only 3days recorded maximum compressive strength of 74.15N/mm 2. However at 90 days, cubes that were water cured for only 28 days recorded the maximum compressive strength of 77.58N/mm2. The sorptivity and coefficient of water absorption did show improved pore structures and reduced permeability as water curing days increased.

An Approach for Project Scheduling Using PERT/CPM and Petri Nets (PNs) Tools
The Petri Nets are more powerful models as compared to the PERT/CPM charts. The Petri Nets show the same type of scheduling constraints as the PERT/CPM charts does. We can easily convert a PERT/CPM networks to a Pe...
