This test method is used to determine the time of setting of the cement by VICAT needle apparatus. The knowledge of the setting time of the cement is always helpful in deciding the time duration to mix, transport, place and compact the concrete effectively. We always prefer a larger initial setting time so that we can mix, transport and place the concrete easily. According to ASTM specifications, the initial setting time shall not be less than 45 min but in the field we prefer an initial setting time not less than 90 min. A smaller value of the final setting time is always preferred in order to avoid large expenditures on the formwork. According to most of the specifications, the final setting time shall not be greater than 10hrs and shall not be less than (90 + 1.2 x (initial setting time)) min.]]>

0 Lightning Related Casualties in Bangladesh. /slideshow/a-case-study-on-lightning/85921051 booksl-180109153551
Information on fatalities in Bangladesh as a result of lightning flashes has been extracted from a database on disastrous weather events of the Department of Disaster Management Bangladesh, records dating from 1990 to mid-2017 indicated that about 3056 persons have been killed by Lightning strikes in Bangladesh. The maximum number of Lightning fatalities is observed in the district of Chapai Nawabgonj is 140 which rate of fatalities is 3.57 per million per year. And for Sunamganj is 132 which rate of fatalities is 2.24 per million per year. The spatial variation shows that Lightning are higher over North side for Bangladesh. A significant number of males (74%) have been killed by Lightning flashes compared to females (9%), and children (17%) in Bangladesh, which is most likely due to the larger proportion of males working and moving outdoors in lonely conditions. The overall fatality rate is about 1.09 % per million populations per year in Bangladesh. The lightning fatalities are significantly more common in the pre monsoon season. Therefore, this study provides useful information on the risky lightning time in Bangladesh to indicate a public awareness and lightning safety. ]]>
