    use of High Performance Fiber Reinforced Autoclaved Aerated Concrete (HPFR/AAC) with a focus on architectural application. I am particularly interested in fiber reinforced concrete technology used to optimize some mechanical properties of final products. During my master’s degree, I applied this principle in my thesis research titled, “Behavior of Steel-Polypropylene Hybrid Fiber Reinforced Concrete”, which is focused on mechanical behavior of concrete elements based upon fiber types and volume percentage

    CHAPTER 3 Project Description 3.1 THEORITICAL CONCEPTS ABOUT FIBER REINFORCED CONCRETE Concrete being a brittle building material and having low tensile strength is unfit to resist tension until duly reinforced. The concept of using fibers to reinforce building materials is not a nascent concept this method has been old and been run by intuition. Hoarse hairs and straws had been used in old times to prevent plaster material from cracking. More recently when Portland cement started evolving, attempts

    736 Words  | 3 Pages

    Everyone has his or her goals in the lifetime. So do I; personally, I plan goals ahead so I would get the expectation of what I am living for at the present and in the future. First, I have to look further at my career. It is my dream to be an architect. I always love to design new and interesting-looking buildings that would appear futuristically modern and à la mode. It is, off course, easier said than done to merely say that I will be an architect in the future. It requires at least the professional

    This paper presents the results of an experimental study on the tension stiffening response of fusion bonded epoxy coated bars embedded in self compacting concrete (SCC). 18 numbers of direct tension specimens recommended by RILEM standards are used with modified specimen lengths of 40 and 50 times the diameter of the bar. From the study it is concluded that fusion bonded epoxy coating on bars has a negative effect on the tension stiffening of SCC. The reduction ranges from 9.4 % to 32% .The tension

  • Essay On Concrete Materials

    Concrete materials are still a dominant material for construction due to its advantages suchas workability, low cost and fire resistance as well as its low maintenance cost. It is formed from a hardened mixture of cement, fine aggregate, coarse aggregate, water and some admixture. Massive exploration of the natural resources for producing concrete affect to the environment condition and global warning. We have responsibility to reduce the effect of the application of concrete materials to environmental

  • Cantilever Disadvantages

    978 Words  | 4 Pages

    CANTILEVER: A cantilever is a rigid structural element, such as a beam or a plate, anchored at only one end to a (usually vertical) support from which it is extended. This could also be a perpendicular connection to a flat vertical surface such as a wall. Cantilevers can also be constructed with trusses or slabs. When a cantilever is subjected to a structural loading, it transfers the load to the support where it is forced against by a moment and shear stress.  Moment of force is the tendency of

  • Ovality In Pipe Bend

    916 Words  | 4 Pages

    Abstract Pipe bends are considered the critical components in a piping system. In the manufacturing process of pipe bends, it is difficult to avoid thickening on the inside radius and thinning on the outside radius. The cross section of the bend becomes non circular and the acceptability based on the induced level of shape imperfections. Considering those shape imperfections it is necessary to have an accurate estimate of pipe bend limit load under internal pressure. ovality is the shape imperfection

    Mortar is a workable paste of cement, sand and water which is used to fill the irregular gaps, voids and bind the masonry units together. The cement mortar is also used in plastering of wall structures in order to give a smooth finish and protect the structure. But cement plaster possesses low strength, absorbs more water and large number of pollutants from the atmosphere and deteriorate the structure which leads to surface cracks and damping. Thus in order to suppress these defects, cement plaster

    Truss engineering is the design and creation of trusses that are made of one or more potential materials. Trusses are crafted from a straight and slender pieces of material manufactured then connected at various joints to form a triangular shape. The common purpose of truss is to construct a large structure with the shape and design of truss adding strength and weather resistance to the overall structure(Šimi & Ilijaš, 2012). Truss can be designed as planar trusses, which are a two dimensional shape

    v) Cantilever Racks. This kind of storage rack is called due to the leverage technique used to support the load-bearing arms (Figure 7). Cantilever racks typically contain a row of single upright columns, spread out several feet apart, with arms spreading out from one or both sides of the upright to form foundations for goods storage. The columns rest on the warehouse floor, avoiding the structure from toppling backward or forward, and diagonal and horizontal bracing between uprights avoids the

    Concrete is an artificial stone-like material used for various structural purpos-es. The word concrete originates from the Latin word concretus which literally means compact or condensed. Concrete has been used for many amazing things throughout history, including architecture, infrastructure and more. The Egyptians were using early forms of concrete over 5000 years ago to build pyramids. They mixed mud and straw to form bricks and used gypsum and lime to make mortars. Joseph Aspdin of England is
