attain those achievements were the invention of concrete and arches. 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

Chapter II Review of Related Literature and Studies Related Literature Polystyrene Commonly known as ’Styrofoam’ that is one of the most widely used type of plastics. It is a strong plastic created from erethylene and benzine that can be injected‚ extruded‚ or blow molded; making it a very useful and versatile manufacturing material. It is also a rigid‚ transparent thermoplastic‚ which is present in solid or glassy state at normal temperature. But‚ when heated above its glass transition temperature

crusher g equipment is necessary. The raw materials mainly are granite‚ limestone‚ basalt‚ pebbles etc‚ through a series of crushing and screening equipment in order to reach required level. Artificial sand is widely used in road construction‚ concrete industry‚ etc. As the field of industry application gradually expanded‚ the gradual application of natural sand work more and failed to keep pace with the various sectors of modern world development needs. For the most part‚ artificial sand is produced

Figure 1 Strip Foundation (Chudley and Greeno 2005‚ p.63‚ figure 2.2.1) A strip foundation is a continuous‚ longitudinal strip of concrete‚ which is designed to spread the load of the building through the walls to the subsoil below. As shown in the figure above‚ the projection beyond the face of the wall should be at least the thickness of the foundation‚ to comply with the building

nature. The Unité is more than merely a summation of Le Corbusier’s earlier work; however‚ it’s different from the rest of his work‚ due to the sense of mass‚ texture and surface. The Unité exposes shuttering board marks versus the precast concrete. archidialog.com Le Corbusier set out to design a tower block that was a “magisterial work of architecture‚ nobility‚ community‚ elegance‚ and happiness‚” all qualities present in a Diaz2 steamship.

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

well-printed specimens was a little higher( little larger) at 2350 kg/m3. This was likely because the concrete hopper was gently vibrated before delivery of the fresh concrete‚ and the pipe and pump system also provided a small pressure during extrusion. A similar trend occurred in a previous study on wet-spayed mortars (Austin et al.‚ 2000; Goodier et al.‚ 2008). Although this high performance printing concrete has only a sand aggregate‚ the density is much higher( much larger ) than that of ordinary mortars
