In this paper‚ I attempt to look into their origins‚ their effect on Roman’s life and what was the most notable works result from these inventions. Concrete was considered one of the most innovative invention in architecture. It enabled building construction to a whole new level. Before concrete‚ buildings were constructed using brick and stone and other natural materials. Concrete was the first man-made material that can be created

Each panel was pelted with stones to give a speckled appearance. Also cast on the site were 700 concrete bleacher sections‚ weighing from one to three tons each. In all‚ 17‚000 cubic yards of concrete were used for the structure‚ including 300 cubic yards for the arena floor alone. The floor contains nearly 10 miles

Site establishment Planning One of the key successes to most projects is in the planning preparation. It is important to establish the key members of the site team as soon as possible and then establish them on to the site. As much time as possible should be allowed for planning and preparation with the team on site. Planning includes various parts such as the completion of the network diagram‚ cash flow and labour preparation. Preparation Before starting anything‚ the site has to be fully

Cement Rapid Hardening Portland Cement Rapid Hardening Portland Cement(RHPC) is a special purpose cement used in concrete to achieve a higher rate of early strength development‚ compared to using Normal Cement. The improved early performance of RHPC is achieved principally through increased product fineness. Typical applications of RHPC include precast concrete production‚ concrete masonry‚ urgent repair work and cold weather concreting. Extra Rapid Hardening Cement An extra rapid hardening
