Original Design Planning The Barclays Center lies on a 22 acres land area with the original design as shown in figure 2. The arena has a conspicuous canopy 85ft high and cantilevers right above the main entrance and supported by 135,000 steel structure which spans through the length the roof and below the roof (Barclays Center, 2016). Once complete, the indoor arena had a space of 675,000. The arena also has a steel oculus which reaches 80 foot high. The arena was also designed to have a green roof

Post tension concrete is an advanced technique in the construction industry. It promotes higher loading concentrations, longer spans, thinner slabs, lighter structures and rapid constructions. The seventh sense apartment project in Colombo 7 is one of the first ongoing post tension constructions in Sri Lanka at the moment. I wish to observe this technique and intend to identify the setbacks in the system to check the suitability of such a technology in this environment. Currently they are constructing

The use of tyre- derived aggregate (TDA) was also tested as an aggregate for light rail ballast tracks in the sub ballast layer due to its absorption of impact properties compared to soil. A study proved results revealed that TDA efficiency in terms of vibration reduction was in the range of 17–46 dB when the impact was applied to the ballast and it was in the ranges of 6–32 dB and 6–47 dB while impact locations were on the sleeper and rail, respectively. Overall, it was proven that TDA with the

For the past week, I have spent every waking hour trying to figure out an incident that occurred in my front yard: what had happened to a 400-pound cement flower planter, to be exact. On one relaxing Saturday evening in late November 2015, my sister came to visit and had noted our cement planter had been tipped over. With no account of who did this or when it had happened, I delved into the mystery of how this massive planter had tipped over. Before I get into this story, I’d like to point out

My concrete working experience I have learnt many skills helping me day with work pouring concrete and laboring for block layers. First let me give you a little background. My dad was worked as a bricklayer since he was sixteen. He has done the same type of work for most of his life, and that's where I come in. My first job was in the summer of 2012 My dad asked me if I wanted to go along and help him with a side job he had going. I said sure and we headed out around nine o'clock. Our first

Trying to decide which material to pave your driveway with can often be a confusing task when you consider that there are many different options available to you that can all prove to be very beneficial in their own ways. However, there are a few reasons to pave your driveway with concrete instead of those other options, such as the three listed below. The Concrete Can Be Customized One of the biggest advantages that concrete has over the other driveway paving options is that the concrete can be

hydration schemes and some feasible expansion mechanisms of the expansive additives are described. 1. Introduction In the hydration reaction of Portland cement, the absolute volume of hydration products formed is less than the total volume of the reacted cement and water. This volume reduction is called the chemical shrinkage. After setting of the cement paste, microstructure of the paste is developed as a result that the paste is not able to change its bulk volume freely; therefore, only a fraction of

naturally cementitious and is commonly used as a replacement for cement material in concrete. In this paper our study is mainly confined to a brief study of GGBFS, its production, composition and applications. It further focusses on examination of changes occurring in the properties of OPC concrete such as strength development, setting time, consistency, durability, sustainability, permeability and appearance on partial replacement of cement with different percentages of GGBFS. We conclude that in recent
