Fundamentals of Building Construction The Concrete

What is concrete? Concrete is a composite material used widely in the construction industry. Concrete is basically a mixture of cement, water, aggregates and admixture (sometimes). Cement is a fine gray powder that consists of oxidizes calcium, silicon and aluminum. The aggregate used is normally gravel, crushed stone or sand. Admixture is a solid or liquid substance that gives a certain characteristics of the concrete. The cement reacts with water chemically and binds the aggregates together through a process called hydration during hardening or curing of concrete. It means that water helps in the hardening of the concrete while the cement bind the aggregate and also react with water to form a solid mass. Concrete is one of the most†¦show more content†¦Pre-stressed concrete is a solid structure whereby stretched reinforcement bars surrounded by concrete. The purpose is to increase the capability of the beam to carry a much greater load with the same amount of concrete and reinforced bars. Ready-mix concrete is a concrete that is manufactured in a factory. The quality of ready-mix concrete is ensured because the concrete has been graded. Precast concrete is a concrete structure that is manufactured in a factory. The precast concrete will be transported to a construction site. Precast concrete saves man power, therefore less workers are needed in the construction site. It also saves time and cost, thus the construction can be constructed in time. Precast concrete has also a better quality comparing to site cast concrete structure. Terrazzo is a flooring material made by grinding and polishing a concrete. The concrete consists of chips of marble or granite in different size and color. Terrazzo often used as decorative flooring patterns because it has various color and texture. Urbanite is used to refer to pieces of concrete from demolition sites. It can be used to create a walkway by recycling the concrete pieces. Reinforced Concrete Basically, reinforced concrete is a type of concrete in which metal bars or wire is embedded to increase itsShow MoreRelatedArchitecture And Modern Architecture749 Words   |  3 Pageshave homes and can survive. It is interesting to consider that architecture began in the Crude Ages. Within architecture, buildings must have to main types of structures. Modern architecture is a type of architecture that focuses more of aesthetics than on function. In order to understand this topic, it is first necessary to know about architecture’s history, the fundamentals of architecture, and the modern aspect of architecture. The first thing one must understand is the history of architectureRead Moreâ€Å"It is not in the stars to hold our destiny but in ourselves.† ― William Shakespeare My decision700 Words   |  3 Pagesmotivated to follow my ambition. I was always fascinated with buildings (residential and commercial). The thought that how they are made and what makes them strong enough to support huge weights kept me thinking.

Although some of their premature concepts were acquired from the ancient Greeks and Egyptians, Roman architects transformed the body of architecture for all time to come, offering buildings and structures that has never been before, along the side of public buildings and infrastructure that could be used by different civilizations globally. As shown in above figure, Roman architecture was at its pinnacle during the Pax Romana stage, a duration in which the Roman empireRead MoreStatement of Purpose for Education Leading to a Career as Construction Project Manager689 Words   |  3 Pagescertitude that will help bridge the gap between dreams and reality.

The vast, varied land and the culture in this abundant place has a deep and lasting impact to the architectural design traditions—Tectonic. Tectonic can be regarded as one distinctive characteristic which is relating to building or architectural construction. It also gives ability for people to read a structure, or see how a structure was put together. Among those architects who had used this tradition in their designs, Donovan Hill and Glenn Murcutt, as Australian architectures, haveRead More3d Concrete Printing With Sustainability1462 Words   |  6 Pages3d concrete printing with sustainability Abstract: 3D printing is unprecedented innovation that promises to be extremely valuable as manufacturing technology with a very various user. 3D concrete printing is an innovation of erection process that will provide significant progress in construction industry.

INTRODUCTION Concrete is a vital construction material having high compressive strength and comparatively low tensile strength. Based on fracture toughness values, steel is at least 100 times more resistant to crack growth than concrete. Concrete in service thus cracks easily, and this cracking creates easy access routes for deleterious agents resulting in early saturation, freeze-thaw damage, scaling, discoloration and steel corrosion. The concerns with the inferior fracture toughnessRead More3d Concrete Printing With Sustainability Essay1462 Words   |  6 Pages3d concrete printing with sustainability Abstract: 3D printing is unprecedented innovation that promises to be extremely valuable as manufacturing technology with a very various user. 3D concrete printing is an innovation of erection process that will provide significant progress in construction industry.
