ISSN 1813-7822 Effect of Addition of Steel Fiber on the Compressive Strength of Composite Concrete Materials under High Temperatures (Experimental & Statistical Work) Asst. Lect. Sawsan Akram Hassan Civil Engineering Department‚ College of Engineering Al-Mustansiriya University‚ Baghdad‚ Iraq Abstract This study presents the benefit gained from using steel fiber reinforcement on concrete mixture. The effect of fire on compressive strength is investigated. Two different tests‚ one

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. Le Corbusier was interested in using the

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

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
