| General note | ABSTRACT<br/><br/>Growing population and shifting from rural to urban areas have posed lest of<br/>problem. One among them is the accommodation particularly in areas Where space.<br/>problem is dominant's has construction of new building with more accommodation.<br/>space in place of old structures is necessary. This produce huge quantum of concrete<br/>waste this waste generally goes to landfill which need good resources to deal with the<br/>problem. An automotive of it is to make use of concrete waste in new construction.<br/>Therefore research to evaluate such possibilities started and is active these days.<br/>This research were conducted experimental evaluation of strength deflection and<br/>cracking behavior of reinforced of concrete slabs made with recycled aggregate from<br/>demolished concrete waste as partial replacement of natural coarse aggregate. The<br/>replacement is done in 50%, 60%, 70% and 80% proportion to compare the results<br/>one batch of slab is cost with 100% natural aggregate.<br/>Demolished concrete is collected from various location of Nawabshah. Bulky pieces<br/>of concrete are hammered down the maximum size of I " inch followed by evaluation<br/>of basic properties of aggregate. In addition to slabs, four cylinders from each batch<br/>of concrete are also prepared to evaluate compressive strength. For all batches of<br/>concrete 1:2:4 is used with 0.45-0.55 water cement ratio. Cylinders are tested for<br/>compressive strength and maximum reduction in strength is obtained as 12.6% for<br/>50% replacement of natural coarse aggregate with recycled concrete aggregate. All<br/>slabs are tested by applying central point load. Average reduction in load carrying<br/>capacity is recorded as 7.1% for 50% replacement of natural aggregates. Maximum<br/>deflection recorded is 4.4mm which is with in allowable limits of ACI 318. Cracking<br/>behavior of all slabs is also observed and it is found that cracking pattern remained<br/>almost same for all models how ever reduction in cracking load with increased<br/>percentages of recycled aggregate is recorded. Based on result it is concluded that<br/>coarse aggregates from demolished concrete can effectively be used in reinforced.<br/> |
